Abstract: Management of insect pests of cotton depends on the application of chemical insecticides in Pakistan. Use of chemical insecticides induce resistance in insects and destroy the natural pest control agents. Therefore, alternatives to insecticides are receiving much attention. Studies to manage the insect pest through augmentative releases of egg parasitoid, Trichogramma chilonis and predator, Chrysoperla carnea, indicated that biocontrol technology suppressed the infestation of insect pests of cotton to sub-economic levels. Low establishment of egg parasitoids was recorded in the early crop growing months and gradually increased to peak during the month of October. Whereas, maximum field establishment of C. carnea was recorded in the month of August.
