In 1983, the application of pheromone fan method to control cotton bollworm, achieved the desired results. In 1984 continue to verify in North Harbor.

The dosage forms still contain a sandwich pouch containing pheromone 1.33 g / pound, and dispense 150 pouches per mu for every 4.5 square feet. 1-3 generations co-cast 5. 2. Experimental area of 293.1 acres, to release the main capsule type, supplemented by chemical pesticides. Control area is still located about 2 km away from the experimental site of the Red Lake four teams, covering an area of 42.1 acres, the control of a single application of chemical pesticides. 3. Experimental area and control area were set to catch the water catch basin for moth monitoring indicator (unified with 2 mg /
