Laboratory study was conducted to determine the efficacy of insecticidal plant extracts Azadirachta indica A. (Juss), Lantana camara L. (Verbenaceae), Eupatorium odoratum (Asteraceae), Tephrosia vogelii Hook, Afromomum melegueta K.M. (Schumann) and Ocimum gratissimum (L) leaves against groundnut bruchid beetle (Caryedon serratus), a synthetic insecticide (Cypermethrin) (10EC)) under ambient condition temperature relative humidity (30°C 72%). One hundred grams shelled weighed into jute bags treated with powders plants. Both untreated were then infested newly emerged adult C. serratus (20 per bag) covered. The experiment laid out in Completely Randomized Design (CRD) replicated four times. Parameters assessed included number egg oviposited, eggs hatched (eclosion) adults that from each treatment, total developmental period (egg – adult), sex ratio finally percentage germination seeds. Data collected analyzed using analysis variance treatment means separated Duncan multiple range tests at P ≤ 0.05 level significance. Results showed indica, camara, T. vogelli, O. seeds significantly recorded lowest mean eggs, reduced damage by increased compared E. control. In conclusion, have potentials as alternatives insecticides management resource poor farmers.
