Bio efficacy of microbial, botanical and chemical pesticides on adult emergence of Trichogramma chilonis and contact toxicity on adult of larval parasitoid Bracon hebetor

Abstract: Indiscriminate use of non-selective pesticides in agriculture has several detrimental effects, of which the harm caused to natural enemies. The present experiment was carried out to find out the toxicity of some ecofriendly pesticides on Trichogramma chilonis and contact toxicity of Bracon hebetor under laboratory conditions. Contact toxicity of Bracon adult, after four days of exposure, spinosad 45% SC @ 0.01% caused lowest mortality (12.50%). The adult emergence T. chilonis ranged from 29.50 to 91.50 per cent with highest emergence in NSKE @ 5%, i.e 90.50%. Pesticide treated Corcyra eggs were parasitized by T. chilonis in the tune of 44.50 to 92.25% and maximum parasitisation 92.25% was observed in NSKE at 5%. From the findings it can be concluded that T. chilonis and B. hebetor may be successfully utilized for IPM programme in filed condition along with microbial pesticides such as B.t. and spinosad 45% SC and botanicals NSKE.
