Abstract
Powders and ashes from Vernonia amygdalina were evaluated for their efficacy as contact insecticides on cow pea bruchid,Callosobruchus maculatus in thelaboratory at ambient tropical conditions of temperature and relative humidity.The powders and ashes were applied at rates 0.0(control),2.00g/20g of cow pea seeds.The result indicated that the plant ashes and powders tested as contactinsecticides significantly(P<0.05)reduced the number of tested insects. However, stembark ash and powder were the most toxic to C. maculatus that evoked 100% mortality of adult cow pea 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.
