Insect growth regulatory activities from oils of camphor and clove against Spilosoma obliqua
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 3
Abstract
The present study was conducted to evaluate the insecticidal and growth regulatory activities of clove oil, Syzygium aromaticum and camphor oil, Cinammomum camphora against Bihar hairy caterpillar, Spilosoma obliqua. The fourth instar larvae were subjected to topical application by microapplicator syringe with doses of 2.5, 2.0, 1.5, 1.0 and 0.5 μl/larva. Camphor oil was most effective at 2.5, 2.0 and 1.5μl dose causing death of larvae ranging from 76-90%. It showed a strong growth regulatory activity with no adult emergence at the highest concentration. Clove oil was effective in reducing adult moth population to 27% at highest dose of 2.5 μl. Only this dose could cause larval mortality of about 60%. The study shows potential of these oils to be utilized as insecticides or antibiosis mechanism to suppress the population of S. obliqua.
