Comparative Toxicant Efficacy of Some Novel Insecticides against Metamorphosis of Papilio demoleus (L.) Larvae

The Papilio demoleus is a key pest of citrus orchards found throughout the year. Their infestation causes defoliation, retards growth, and yields reduction. five insecticides namely; Emamectin Benzoate 1.9 EC, Belt 480g/L SC (Flubendiamide), Helmet 40 EC (Chlorpyrifos), Coragen (Chlorantraniliprole 18.5% SC), Regent 5% (Fipronil) were tested on C. limon orchard leaves against larvae population lemon butterfly under laboratory conditions during, 2020. maximum cumulative effect all treatments was observed in three replications. mortality efficacy recorded after 24, 48, 72, 120, 168 hours post-sprays. result revealed that pesticide proved with larval (66.64±8.16%) followed by (60.26±0.76), (59.66±7.72), (57.14±7.65), (56.18±7.50), respectively. It concluded insecticide provided better % population. one-way ANOVA showed significant difference among at p<0.05 level. After application reduced movement, skin became wrinkled, thin, yellow-brown pigmentation visibly appeared loose muscle concentration releasing hyper-salivation semi-liquid frass. Thus; it recommended to be applied time interval basis suppress butterflies
