Abstract

Callosobrochus maculatus (F.) (Coleoptera: Bruchidae) is the most destructive pest of stored cowpea worldwide. The use of synthetic pesticides against C. maculatus have proven effective but with great concerns on its resulting effects such as pest resistance and residual toxicity threatening food security. The toxicity effect of Citrus sinensis and Citrus limon were evaluated against the adult C. maculatus. Four concentrations of C. sinensis (20%, 15%, 10%, and 5%) and C. limon (5%, 15%, 10%, and 20%) including a control of only acetone used as standard comparative to treat the pest. It was set up in completely randomized design. Results were recorded at 12 hourly intervals for 3 days. At highest concentration of 20% for Citrus sinensis, mortality recorded was 87% and at lowest concentration, it recorded 50%, while the LC50 and LC90 were 5.8% and 30.7% respectively, LT50 and LT90 were 27.2 and 45.3 hours respectively. Similarly, C. limon at highest concentration recorded 76% and at lowest concentration recorded 43% while the LC50 and LC90 were 8.4% and 57.7% respectively, LT50 and LT90 were 12.2 and 43.1 hours respectively. It was observed from the study that mortality was concentration and time dependent, therefore, C. sinensis and C. limon could be used as good alternatives to synthetic pesticides which has adverse effects on man and food crops.
