Insect of Honeybee

This topic provides information about Insect of Honeybee.

The Greater wax moth (Galleria mellonella)

The greater wax moth is often reported to cause damage both to honeygreater wax bee colonies and to bee products in tropical and sub-tropical Asia. It is observed throughout the year but its occurrence is severe during July to October and November to December. Empty combs, rendered wax, comb foundation and bee collected pollen, if not properly stored and left unattended, almost always suffer considerable damage from wax-moth infestation.

According to many reports, the wax moth is a major pest of Apis cerana, often causing colonies to abscond. In wax-moth attacks on colonies, the adult female enters the hive at night, through the entrance or cracks in the walls, deposits her eggs directly onto the combs or in narrow crevices that permit ovipositor and offers protection against removal by worker bees. From 50 to 150 eggs are laid in each batch; they are glued together and adhere firmly to the surface on which they are laid.

The newly-hatched Galleria larvae feed on honey and pollen, and then burrow into pollen storage cells or the outer edge of cell walls, later extending their tunnels to the midrib of the comb as they grow. At this stage the developing larvae are quite safe from the worker bees. As they advance into the combs, they leave behind them a masses of web and debris; the complete destruction of unattended combs usually ensues within 10-15 days. mothIn addition to stored pollen and bees wax, larvae of the greater wax moth will also attack bee brood when short of food. The development time of Galleria larvae depends on two factors - food availability and temperature. Whereas in tropical climates the larvae require only 18-20 days before spinning cocoons and becoming pupae, in cooler climates this period may be extended. When weak colonies are infested, the symptom of ‘gallerias’ is frequently observed: the emerging adult worker and drone bees are unable to leave their cells because their bodies have been tied up by silken threads spun by the Galleria larvae.

The Greater Wax Moth - Management

Following management practices can be undertaken to avoid wax moth infestation in apiary and stores.

Apiary Management:

  • Weak colonies can be protected against wax moth by making them strong, for example by uniting two or three colonies. The moth usually enters a hive to her eggs when colony becomes weak.
  • The entrance of a weak colony should be reduced to avoid the entry of adult moths. Other holes or cracks or crevices which can serve as entrance to the hive will surely be used not only by the moth but by other hive predator as well. Such entrances should be sealed off as soon as they are discovered.
  • Regular cleaning of bottom board is necessary to remove debris that may harbour young larvae and eggs. Attention should be given to the joint of bottom board which serves as the safe sheltering and hiding places of the larvae.
  • The damaged infested combs should be exposed to sunlight for 15-20 minutes and debris be burnt and buried.

Storage Management:

  • A water soluble concentrate of spores of Bacillus thuringiensis Serotype 7 provides an excellent protection of stored combs without affecting the organoleptic properties of the honey.
  • Stack the empty combs in supers (up to 8-9 super) leaving some empty space in lower most super. Make it airtight by using mixture of mud and dung .
  • Avoid fumigation with naphthalene, ethylene die-bromide and PDB as they lead to their residues in honey.
  • Fumigate the empty combs with sulphur powder @ 230g/m3 and after that seal them properly. Store the empty combs at low temperature (0 to -10°C) either permanently or for 5 hours. All the stages of wax moth are destroyed at low temperature.

The Lesser wax moth (Achroia grisella)

The lesser wax moth is generally smaller than the greater wax moth, except when the latter is dwarfed owing to poor diet during its larval stage. Adult Achroia grisella are silver-grey in colour, with a distinct yellow head. The insect is quite small, with a slender body: normal body lengths of adult female and male are about 13 and 10 mm, respectively. The life-span of the adult female is about seven days, during which she can lay 250 to 300 eggs.

Infestation by the lesser wax moth usually occurs in weak honey bee colonies. The larvae prefer to feed on dark comb, with pollen or brood cells. They are often found on the bottom board among the wax debris. As larvae prefer to form small canals between the bottoms of the brood cells the brood is lifted. The bees continue constructing cells heading upward leading to the typical scratched comb surface.

Management : The methods employed in controlling Galleria mellonella are equally effective for the control of Achroia grisella.

Ants, Wasps  and Hornets


All type of ants are among the most common predators of honey bees in tropical and subtropical areas. They are highly social insects and will attack the hives en masse, taking virtually everything in them: dead or alive adult bees, the brood and honey. In addition to this destruction, they can also be a nuisance to beekeepers and may sometimes cause pain from their bites. Apiaries of Apis mellifera under ant attack become aggressive and difficult to manage; weak colonies will sometimes abscond, which is also the defense of A. cerana against frequent ant invasions. Many ant genera and species are reported to cause problems to traditional beekeeping.

Control: The following management measure may be taken by beekeepers to control ants attack in beekeeping. Keep the apiary clean and place the hive stand post in bowls of tin or plastic or earthen pots filled with water. Clean the bowls regularly to avoid the formation of bridges or earth that can be crossed by ants. Replenish the liquid frequently.

Wasps and Hornets

These insects are dangerous against the honey bees in all Asian countries including India. Among the most frequently reported are social wasps of the genus Vespa, which are widely distributed throughout the world. Colonies of both A. cerana and A. mellifera are frequently attacked. Hornet invasion of A. cerana colonies generally causes the bees to abscond, and similar behavior is reported of weak colonies of A. mellifera. In addition to hornets of the genus Vespa, other wasp species have occasionally been reported to cause damage to apiaries.

Table 2 lists wasps and hornets that have been reported as major predators of the two honey bee species in Asia. Predation by Vespa spp. on commercial apiaries is generally a rainy season problem. Hornet’s attack on apiaries reach their peak of intensity during September-October, whereas in tropical countries the most serious wasp invasions take place during the monsoon season, particularly from late June to August. Apiaries situated near the foothills and tropical forests suffer more acutely than those on the plains.

Managements of Wasps and Hornets

To manage the wasps and hornets problem in beekeeping, beekeepers are advised to adopt methods such as bait-trapping, trapping at the hive entrance and using protective screens. Locating hornet nests by following flight passes of individual wasps back to their nests and then destroying the nests may be very time consuming and, if too many of these nests are in the area, not very efficient. Where labor costs are not prohibitive, beekeepers have resorted to capturing and killing individual hornets foraging in the vicinity of their apiaries. In some areas, this approach has proved to be quite effective, largely because the period of most intense hornet attacks is only two to three months. It has been seen that the real damage inflicted by hornet attacks on honey bee colonies occurs during the slaughter and occupation phases. Killing hornets in the early stage of predation has the effect of disrupting the hunting phase and preventing the predation process from reaching the more destructive phases. Mass destruction of the colonies is thus prevented or, at the least, minimized.

Preventive measures

  • Keep bee colonies strong in the apiary and ensure proper food availability in the colonies. Provide artificial feeding if required. Reduce the hive entrance to give passage to only one or two bees at a time.
  • Killing the wasp or hornets by flapping at early stage of predation is more effective in disrupting the hunting phase and preventing the predation process from reaching the more destructive phase. Thus losses can be minimized.
  • Beekeepers are also advised to migrate the bee colonies to safer place or search out the wasp nests in vicinity of the apiary and destroy them.

Honey Bee Mites

Parasitic mites are among the most serious enemies of honey bees with which beekeepers have to cope. The success or failure of beekeeping operations with Apis mellifera depends largely on mite management. Several major factors exacerbate bee mite problems on the continent. First, all known major species of parasitic honey bee mites are currently present in Asia, most being native to the continent. Second, the complete eradication of the mites from an apiary is impossible, because the feral nests of native bees infested by the parasites serve as reservoirs of mite reinfestation of domesticated honey bee colonies. Moreover, some mite species are able to survive, or even thrive, on more than a single species of host bee. Several species of mites have been reported as causing devastation to both A. mellifera and A. cerana beekeeping operations throughout country, though not all mite species found within the hives or in association with the bees are true parasites. Several species of pollen-feeding mites are occasionally found in hives or attached to foragers. These phoretic mites are not harmful to beekeeping. Table 1 contains a list of parasitic and phoretic mites reportedly found in association with honey bees in the country.

Varroa Mite (Varroasis)

This mite is a native parasite of A. cerana throughout Asia. Since the initiation of beekeeping development projects with A. mellifera on the continent, it has been reported as causing damage in both temperate and tropical Asia. The overall effect of varroa infestation is to weaken the honey bee colonies and thus decrease honey production, often seriously. Occasionally in A. mellifera, and more frequently in A. cerana, heavy infestation may cause absconding. Today this mite is found throughout the world, except for Australia and New Zealand of South Island.


Varroa destructor is quite large, as compared with other mite species, and can be seen with the unaided eye. The shape of the adult female is distinctive: observed from above, the width of the body is clearly seen to be greater than the length, i.e. about 1.6 x 1.1 mm. The mite is reddish brown in colour and shiny and the body is dorsoventrally flattened covered with short hairs (setae). Adult females of V. destructor are found inside brood cells or walking rapidly on comb surfaces. Individual mites are often seen clinging tightly to the body of adult bees, mostly on the abdomen, where the segments overlap, between the thorax and the abdomen and at the ventral entry. Adult males, and the immature stages of both sexes (egg, protonymph and deuteronymph), are not commonly seen outside the brood cells. All immature stages of the parasite live inside the brood cells. They can be observed when infested cells are opened and the brood is carefully removed. The immaturecausesmites are bright white and the adult females are brown, while male mites are smaller than females and are rarely seen since they are only found inside brood cells.


Varroa causes injuries to honey bees by direct feeding. The adult female pierces the bees’ soft intersegmental membrane with their pointed chelicerae and sucks the bees` haemolymph (‘blood’). The adult bee, however, is only damaged if the infestation is severe. The condition of a honeybee colony being infested with Varroa mites is called varroasis. If more than one parasitic female mite infests the brood cell the brood decays or deformations occur including shortened abdomen or deformed wings. If only one mite infests a cell symptoms may not be visible, although the bees’ life-span is considerably shortened. Moreover, the bee’s behavior may be disturbed, e.g. in orientation or gathering food. Infested bees often have a reduced fat body that hampers the functioning of their glands or increases their susceptibility to pesticides. The semen production of drones may be considerably reduced. Varroosis is a multifactorial disease. Virus diseases that may have caused little damage before infestation by varroa mites often accompany it. Normally, the exoskeleton protects the bees from many virus infections. However, the mite penetrates this natural barrier transferring viruses or stimulating the multiplication of viruses with its saliva. In turn viruses seem to speed the development of varroasis enhancing the parasite’s virulence. Other diseases such as nosema and sac brood have similar effects.

Moreover, unfavorable climatic conditions or insufficient stocks of pollen and nectar can increase the process of disintegration. Without treatment the colonies normally die after two to three years, management errors may also cause the collapse of colonies. Colonies destroyed by the varroa mite are often left with only a handful of bees and the queen, the other bees having died during foraging or having drifted to neighboring colonies, where the mite population can increase before killing these colonies also. In this way mites may cause colonies to die, as in some kind of domino effect, over wide areas.

The presence of adult bees with deformed wings, crawling on comb surfaces or near the hive entrance, usually indicates a late stage of heavy mite infestation. Several other methods may be used to detect mites. The most reliable, perhaps the most time consuming, is direct sampling by the random opening of brood cells, particularly drone cells. The older the larvae/pupae the easier this procedure becomes. The brood is removed from the cell with a fine forceps and the cell is inspected for the presence of the mites. Between 100 and 200 cells must be opened before an assessment of the level of mite infestation can be made. To inspect adult bees, the bees are captured from the brood combs and placed in jars, into which chloroform, ether or alcohol is introduced on a piece of cotton wool. The bees are intoxicated and the mites crawl on the glass wall. Returning foragers may also be captured by hand at the hive entrance and held up against the sunlight; any mites attached to the bees’ abdomens may be seen. Another method is to use specially constructed zinc, plastic or wood trays, built to the size of the bottom board, with a white or light-colored floor. The trays, equipped with a screen of a mesh less than 2 mm fixed at about 1 cm above the tray floor, are placed on the bottom boards of the hives and are inspected one to three days later for the presence of dead mites. The screen prevents the bees from removing the dead parasites from the hive.

The control of V. destructor is one of the most difficult tasks facing apiculturists and beekeepers throughout the world. The mite is a highly successful parasite, whose life history is well synchronized with that of its host. Two principal approaches to its control are currently available:

Control methods and hive manipulation techniques

Chemical control is by far not a common method of varroa control. The organic acids: formic acid, the ethereal oil thymol may be chosen to treat colonies with brood.

  • Formic acid: Formic acid can kill some of the mites in the sealed brood cells. It is recommended that the formic acid be allowed to evaporate in colonies with sealed brood for at least two to three weeks. In this way, mites emerging from the brood will also be killed. The external temperature should not be less than 12°C (54°F) and not more than 25°C (77°F). The formic acid should be introduced into the colony only in the late afternoon to avoid damage to bees and brood. In addition, physiological tolerance is improved if the entrance hole is wide open. An easier way to introduce formic acid is to use a sponge or a similarly absorbent material. A solution of 50 ml of 60 percent formic acid is applied onto the sponge tissue per comb (Langstroh size). The quantity must be reduced accordingly for smaller comb sizes. A grid fixed above the tissues on the bottom of the hive, will prevent the bees from burning themselves with the acid. The grid should be as far away from the brood as possible. The application can be repeated two times at intervals of ten days.
  • Oxalic acid: Contrary to formic acid oxalic acid does not act via evaporation but through contact with the bees. Thirty two grams of crystal oxalic acid (dehydrate) is thinned in one litre of sugar water (1:1). When handling crystal acid special precautions must be taken because of the health risks. Protective spectacles and acid-proof gloves must be work together with an adequate mouth protector. Depending on the size of the colony 20 to 30 ml of the suspension per chamber are dropped into the bee-ways. A repetition of the treatment can lead to damage to the bees. Applicators are available by which the acid can be evaporated.
  • Lactic acid: Lactic acid is clearly better tolerated by bees and does not cause problems in warmer climatic zones. The disadvantage is that every single comb must be extracted to spray the bees with the acid. The dosage applied per comb side is 8 ml of 15 percent acid. This treatment can be repeated two times at intervals of seven days.
  • Etheric oils: The only etheric oil that is sufficiently affective against varroa mites is thymol. Thymol can be applied as a commercially available ready-made preparation or in crystal form. For this purpose, put 5g of thymol crystal into a gauze bag and keep on the top bars for two weeks. In this way mites emerging from the brood will be covered.
  • Control by hive manipulation: The varroa mite depends on bee brood to complete its development cycle. Since the mite prefers drone brood to worker brood, empty frames are given to the colonies, which will rear drone brood in them. When the cells are sealed, the frames, containing the mites trapped inside the cells, can be removed and destroyed.

Tropilaelaps Mite

Modern beekeeping with Apis mellifera in tropical and sub-tropical part of the Country frequently encounters problems caused by infestation with Tropilaelaps spp. This mite is a native parasite of the giant honey bee A. dorsata, widely distributed throughout tropical part of the country, and whenever A. mellifera is kept within the range of distribution of A. dorsata, mite infestation of the colonies cannot be avoided. Thus, beekeepers consider Tropilaelaps to be a more serious pest than varroa-mites, even though it may be easy to control. Dual parasitism of A. mellifera colonies by both parasites sometimes occurs, the population of Tropilaelaps often being greater than that of varroa, as the Tropilaelaps mite can almost completely prevent multiplication of the varroa mite.

Cause: Tropilaelaps mites are much smaller than varroa mites, although the trained unaided eye can still see them. The adult female mite is light reddish-brown in colour, with an oval-shaped body about 0.96 mm in length and 0.55 mm in width. The mite’s entire body is covered with short setae. A red streak running longitudinally on the ventral surface of the adult female may be perceived through a strong magnifying glass. When the mites are present in a honey bee colony in large numbers, they can be observed walking rapidly on the surface of the comb. They are rarely found on adult bees. In all its immature stages, the mite lives within the brood cells of the bees, feeding on the brood’s haemolymph.

Fertilized adult females enter the cells before they are capped to lay their eggs. The stages of development of the mite are as follows: egg, six-legged larva, protonymph, deutonymph, adult. Adult males of Tropilaelaps do not feed, their chelicerae (the organs originally used for piercing the bees’ integument) having been modified to transfer sperm as with the varroa mite. The life cycle of the mite is well synchronized with that of the host bee.


The damage caused to colonies by Tropilaelaps infestation is similar to that brought about by varroa and the injuries inflicted on bee brood are same. The abdomen of bees surviving mite attacks is reduced in size, and they have a shorter life-span than healthy bees In heavily infested colonies, bees with deformed wings can be observed crawling about the vicinity of the hive entrance and on the comb surfaces, while piece of dead bee brood evacuated from the hive by the house bees can be seen in front of the entrance. Inspection of hives severely infested by Tropilaelaps reveals an irregular pattern of sealed and unsealed brood as found with all brood diseases. Since this symptom can be taken as a sign of a poor-laying queen, the position must be verified. The best means is to open sealed cells gently and inspect them for the presence of the mite. If mites are present, adult females will be seen walking rapidly out of the cells. To obtain a reasonably accurate estimate of the level of infestation, 100-200 cells should be opened and the brood removed with forceps for close inspection.

Control: The chemotherapeutic measures described above for the control of varroa are also effective in the control of Tropilaelaps. Formic acid is effective in its treatment.

Colony manipulation techniques:

Many beekeepers prefer not to use chemicals to control Tropilaelaps, but to manipulate the brood rearing cycle of their infested colonies in such a way that the mites are deprived of sealed and unsealed brood (broodlessness) , their food, for at least two weeks. During this period, a large proportion of the mite population will starve to death. There are several means of creating this brood less situation in infested colonies. In smaller apiaries, the beekeeper can simply remove the brood-comb frames -- both sealed and unsealed-- from the infested colonies and put them in new hives. Before the new larvae hatch, the hives manipulated in this way will be short of brood for two to three days, time enough to starve most of the mites. The new hives with the removed brood frames are given mated queens, which are caged for 14 days, a period that allows most of the brood to emerge, while no new brood has been reared because the queen has been confined. The best time of year to carry out these colony-manipulation techniques is during a heavy pollen-flow season, enabling the colonies to rear brood after the period of brood deprivation. In some Asian regions, this season coincides with the monsoon months, when there is no nectar flow but when pollen is abundant. This is also the season in which beekeepers feed sugar syrup to their bees, rear new queens and propagate colonies. While colony manipulation to control Tropilaelaps is time-consuming, it causes no noticeable harm to the colonies, nor does it affect productivity. The availability of pollen, coupled with the feeding of sugar, enables both the treated and the newly-formed colonies to regain their full strength before the nectar flow begins.

Tracheal Mite (Acarine disese)

This mite, Acarapis woodi, infests the tracheal system of adult bees, queens, workers and drones, which are all equally susceptible to its attack. Since it was first reported in Apis mellifera colonies in Europe in 1921, opinions regarding the extent of the damage it can cause to honey bee colonies have varied. Reports from India and Pakistan indicate that the tracheal mite caused severe loss of Apis cerana colonies.

Cause: A. woodi is a very small mite (0.1 mm) species that lives and breeds within the thoracic tracheae of adult bees . The mite penetrates through the spiracles into the first tracheal pair of the thorax of 10-day old honey bees. There it lays eggs at intervals of a few days. After the deutonymph stage, male offspring emerge after around 12 days and females after 13 to 16 days.


Typical visible symptoms of infestation are presence of crawlers bees around the hive and ‘K’ type wing condition. Indeed, it has been demonstrated that bees severely infested with the mite can forage normally. Nevertheless, some differences exist with regard to the over-wintering capability of infested and healthy colonies. Infestation shortens the lifespan of the individual bees, so that severe infestation of colonies causes them to loose strength and thus increases a colony’s susceptibility to winter losses. The most reliable diagnostic method is laboratory dissection. Samples of 20 or more bees found crawling near the hive and unable to fly are killed, their heads and legs removed and their thoraxes dissected for microscopic examination. If present, the mites are usually found at the end of the first pair of trachea in the thorax.

Control : Chemotherapeutic measures are widely adopted for mite control. Best results could be achieved with evaporating substances such as formic acid and ethereal oils.

Formic acid: Formic acid produces good results by applying by the method as described in varroa control.

Bee Scorpion

This insect usually clings to the legs of the bees and accompanies them to the nest. It is usually observed in the comb of Indian honey bee A. cerana.



Most commonly reptiles are found in tropical forests, woods, grasslands and urban areas. Among the reptile species that are regularly recorded as present in commercial apiaries are, Calotes spp., Acanthosaura spp., Sphenomorphus spp. Arboreal reptiles such as many geckos and skinks can attack bees either near the hive entrance or on the limbs of flowering trees visited by forager bees. Smaller lizards, such as the gecko Hemidactylus frenatus, often hide in the empty space between the outer and inner covers of the hive.

Management: The beekeeper can do little to prevent the loss of foragers to the highly mobile arboreal reptiles, usually well hidden in the trees. Hives placed on stands that are about 40-60 cm high are reasonably safe from reptiles attacking from the ground, coating the legs of the stands with used engine oil or grease may deter the reptiles from climbing up to the hive entrance. A well-kept bee yard that is frequently mowed, without dense bushes, shrubs and tall grass, that provide safe hiding places to the predators, has less chance of suffering losses from reptiles than an untended one.

Honey Bee Eater Birds

In agriculture sector various species of birds may be useful because they are reducing insect pest population from cropping field. Many Birds prey upon many insect species and honey bees are no exception. Once airborne, the bees are virtually defenseless against birds, several species of which can tolerate their venomous stinging defense. The heavy traffic of bees flying in and out of the hives of commercial apiaries provides an exceptional opportunity for insectivorous birds, large numbers of which may be attracted by this situation. The level of damage caused by honey bee eater birds varies. An attack by a single bird or by a few together rarely constitutes a serious problem, but when a large flock descends upon a few colonies or an apiary, a substantial decline in the worker population in some or all the hives may be observed. Whereas the degree of damage to commercial apiaries caused by predatory birds depends largely on the number of the predators and the intensity of the attack, the mere presence of a few predators in apiaries engaged in queen rearing can inflict serious losses.

Management: While beekeepers regard insectivorous birds as pests, sometimes serious, other branches of agriculture generally do not consider them as problematic. In fact, birds that prey on insects are mostly considered to be beneficial to farming, in that they help in the control of insect pests. Where heavy predation by birds on apiary bees tends to occur at fixed periods (e.g. during the migration season of swifts), the most practical means of solving the problem is usually to avoid the birds, through careful site selection and by temporary relocation of the apiaries, at least until the migration period is over. The following management measurement are recommended to beekeepers/farmers for controlling birds problems in beekeeping.

  • Making noise by beating drum and scaring away the predatory birds by slingshots.
  • By using red reflective ribbons around the apiary.
  • Management should also be taken to choose the apiary site away from the bird perching object such as telephone wires, electric poles and other wires, building, trees etc.


Different groups of mammals may be considered as enemies of the honey bee. In general, they prey on colonies for honey and/or brood; some attacks are purely accidental. Such cases usually occur when apiaries are placed in or near forests and are not properly protected.

Pine Martins: The pine marten is tree dwelling member of the weasel family. Pine martens destroy the combs of domesticated as well as wild bee for honey in mostly hill areas. Fencing of apiary may reduce the attack of pine marten.

Raccoons: Raccoons harm the apiary by pulling the farmers from the hive and build a nest to raise their young ones. They will even remove top or inner covers from stacked supers. The honey containers are taken away from the hives and they drink the honey. Raccoons can be trapped by using red reflective ribbons around the apiary.

Bears: Once a bear has tasted honey and brood, it is almost impossible to keep it away from apiaries. Protecting colonies from bear attack is usually difficult, particularly when the animals are large and strong. Bear damage is rather easy to see. Hives are shattered to bits by the bears to get the brood comb and honey. They scatter the equipments around the yard.

Placing the apiary in location out of the bear’s path reduces its attack. Electrified barbed wire fences are often used where bears represent a common problem. Moving hives closer to human habitation is also effective.

Skunks: Skunks scratch the bottom board or the front of hive body to get the bees coming out of the hive and eat the bees. Skunks visit the apiary in the evening time and dark hours. Raising the hive 15 to 18 inches above the ground and use of wire netting around the hive is effective to prevent the skunks.

Rodents: Rodents such as mice and rats are common pest to the beekeeping. They build nest in hive boxes, destroy comb in the frames, and make hole in equipments. In addition, they leave dropping all over the place. Rats can be serious problems in storage areas where bee equipments are kept. To keep mice out of hives, a mouse trap can be placed on the entrance of the hive. Reducing the entrance of the hive to ¼ of an inch, bees will be able to come and go, but mice will not be able to enter. Bait traps can be used for both rats and mice.
