“…The insecticidal sprays are harmful to the environment and responsible for various human health problems. To overcome this problems the use of bio control agents play important role in such as birds stand supreme in control of insect pest due to their increased efficiency to capture and consume large number of insects (Sweetman,1958).The small wasps Trichogramma belonging to the family Trichogrammatidae, Trichogramma have great ability as bio-control agents (Bigler et al 2003) [10] . The wasp Habrobracon hebetor which is ecto parasitoid is effective against Helicoverpa armigera larval parasitoid (Noor-ul-Ane et al, 2018) [34] .…”

H. armigera is a major polyphagous pest for agricultural and horticultural crops. It has wide range of host plants. It is difficult to control due to its polyphagous nature, high fecundity, mobility and diapause. The control of Helicoverpa armigera mainly depend on chemicals, but heavy and continuous use of it lead to resistance to different group of insecticides like cyclodienes, pyrethoids, carbamates and organophosphates. To avoid this resistance we should focus on other methods of control like host plant resistance like non-preference, antibiosis and tolerance. Cultural operations like right time of sowing, ploughing, nutrient management, spacing, crop rotation and biological control by using egg parasitoids like Trichogramma chilonis, larval parasitoids like Compolestis chlorideae, bacteria like Bacillus thuringensis, fungi like Beauveria bassiana and virus like HaNPV.
