Abstract
Powders and ashes from Vernonia amygdalina were evaluated for their potentials as contact insecticides on cowpea bruchid, Callosobruchus maculatus in the laboratory at ambient tropical conditions of temperature and relative humidity. The powders and ashes were applied at rates 0.0 (control), 2.00g/20g of cowpea seeds. The result indicated that the plant ashes and powders tested as contact insecticides significantly (P<0.05) reduced the number of tested insects. However, stem bark ash and powder was the most toxic to C. maculatus that evoked 100% mortality of adult cowpea bruchid after 72 h of exposure. There was no progeny development of the bruchid in samples treated with V. amygdalina. The survival of the bruchid from eggs to adults when treated with the plant part powders showed that there was significantly (P<0.05) more % progeny development in the control compared to others. This study showed that all the tested plant parts powders and ashes were toxic to cowpea bruchid and the powders can be mixed with cowpea seeds to prevent hatching of the eggs thereby aiding their control.
