Sex pheromones (Septa) are insect specific produced artificially in laboratories and used seperately.
American boll worm, spotted boll worm, pink boll worm, dimond back moth, white grubs.
Cut the polythene sheets into required size (2ft. length X 4 inch wide) and make polythene arm. Close the bottom end of the arm with rubber band to prevent the escaping of trapped insects and to flush out them. Wrap and fit the other end of polythene arm with wider end of the funnel with the help of rubber band/wire. Keep the lid of funnel one inch above mouth of the funnel. Make a small hole to place septa/ lure. Fix the trap containing lure in the field with the help of bamboo sticks keeping the lure nearly one foot above the crop canopy.
Lures containing sex pheromones are placed into insect trap and erected in the field at a recommended spacing. The lure will release the sex pheromone at a constant rate over a period of 2-4 weeks. Male moths are attracted and while attempting for mating, fall into a container having pesticide. Thus the female moths in the field are deprived of successful mates and fail to reproduce or lay viable eggs.
