Abstract: Ten plant powders were tested at 2% on five legume seeds for their entomocidal effects against Callosobruchus maculatus. A completely randomized design (CRD) with five pairs of freshly emerged adult bruchids was used to treat 40g of disinfected legume seed types with 2g of the selected plant powders. An analysis of variance was performed on the data on the percentage of oviposition deterrence, hatchability, pest tolerance, and weight loss. Zanthoxylum zanthoxyloides (87.02%) P. guineense (77.36%) and E. aromatica (73%) significantly deterred oviposition. The maximum percentage egg hatched was recorded in G. max (94.71%) and significantly lower on C. cajan with P. guineense (2.33). Ife Brown (20.83%) recorded significantly lowest tolerance compared to M. pruriens (99.17%). Percentage weight loss was significantly reduced in G. max irrespective of treatment and M. pruriens suffer no weight loss. Incorporation of Z. zanthoxyloides, P. guineense and E. aromatica powder proved to be promising biopestici.
