Abstract
This study investigated the antifeedant, insecticidal, and insect
growth regulatory (IGR) properties of solvent extracts from Crotalaria
paniculata and Holoptelea integrifolia against Spodoptera litura
under laboratory conditions. Extracts were prepared using solvents such as
acetone, ethyl acetate, and petroleum ether and tested at five concentrations:
1%, 3%, 5%, 7% and 9%. Acetone extracts of C. paniculata exhibited the
highest efficacy, providing 95.77% leaf area protection, 73.33% larval
mortality, and complete inhibition of adult emergence at 9% concentration.
Similarly, acetone extracts at 7% resulted in 93.56% leaf area protection,
66.67% larval mortality and complete suppression of normal adult emergence.
Ethyl acetate extracts of C. paniculata at 9% demonstrated strong
antifeedant activity (93.33% leaf area protection) and high larval mortality
(66.67%), along with complete suppression of adult emergence. For H.
integrifolia, petroleum ether extracts offered the highest antifeedant
activity (86.20% leaf area protection), while ethyl acetate extracts achieved
the highest larval mortality (53.33%) and complete adult suppression. These
results highlight the potential of C. paniculata as a sustainable
botanical insecticide, with H. integrifolia offering complementary pest
control benefits for integrated pest management (IPM) programs.
