Growth and development inhibitory activities of medicinal plant oils against lemon butterfly
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Present study was carried out to access the effect of 2% concentration of some medicinal plant oils on growth and development inhibitory activities of lemon butterfly, Papilio demoleus. The observations on mean weight gain/larva at two days after feeding (DAF) specified that minimum weight gain (0.018g/larva) or highest reduction in weight gain over control was reported in diet supplemented with Cymbopogan flexuosus- Chirharit (59.10%) and it was followed by Jatropha curcus (56.82%). All the plant oils except Geranium were found effective in reducing the larval weight significantly over control (0.0260g) at 4 days after feeding. The plant oils used in the present investigation revealed different level of toxicity against P. demoleus. Like weight gain, highest larval mortality (%) was reported from the C. flexuosus- Chirharit (53.33%). Further, a significant reduction in the pupal weight was also reported and among various tested oils. Maximum reduction (59.17%) in pupal weight was detected in C. flexuosus- Chirharit while minimum reduction (23.34%) was observed in Geranium essential oils. In the present investigation, C. flexuosus- Chirharit, C. flexuosus- Krishna, Mentha arvensis and J. curcus was effective in reducing growth and developmental parameters of 3 days old P. demoleus larvae.
