Resumo: | Antifeedant and growth regulating activities of PONNEEM, an oil formulation containing neem and pungam (karanj) oils were evaluated along with individual neem and karanj oils and Nimbicidine, a commercial neem-based pesticide against fourth instar larvae of Spodoptera litura (Fab.). Among all the treatments, PONNEEM recorded the maximum antifeedant activity (88.6%) at 0.6%. Neem and karanj individual treatments as well as PONNEEM extended larval duration compared to control. Pupal weight and fecundity were significantly reduced and pupal period was greatly increased by PONNEEM treatment compared to other treatments. The PONNEEM was found to be compatible with Trichogramma chilonis Ishii, an egg parasitoid of many lepidopteran pests, at 0.15, 0.3 and 0.5% concentrations. PONNEEM did not affect the parasitoid emergence significantly at 0.3% concentration compared to control. PONNEEM also showed growth disruption activity against fourth instar larvae.
