Abstrakt: The toxicity of some biopesticides evaluated against neonate larvae of Helicoverpa armigera (Hubn.) revealed that Melia SFE was the most effective (LC50 and LC90 values being 0.010 and 0.07%, respectively) followed by Eupatorium SFE (0.012, 0.009%, respectively), and Neemarin 300 (0.056, 0.296%, respectively). Neemarin 300 showed maximum antifeedant activity (85.46%) followed by Melia SFE (77.59%). Panchagavya showed maximum repellent activity (83.33%) followed by agneyastra (66.67%). HaNPV and Melia drupe extract in cow urine showed maximum mortality (80.00%) through stomach action followed by Eupatorium leaf extract in cow urine (76.67%). The persistent toxicity values revealed that the order of effectiveness was: Neemarin 300 > Melia SFE > Eupatorium SFE > HaNPV > Melia drupe extract in cow urine > Eupatorium leaf extract in cow urine > panchagavya > agneyastra > cow urine. There was no mortality of Chelonus blackburni adults in HaNPV and cow urine treatments. [ABSTRACT FROM AUTHOR]
