The influence of climate on the resistance of Callosobruchus maculatus Fab. to pirimiphos methyl from three Geographical Zones in Nigeria was investigated in the laboratory at 32 ± 2 oC and 70 ± 5 % relative humidity. Samples of cowpea seeds infested with C. maculatus were obtained from twelve locations spread across savannah forest (northern boundary), rain forest and mangrove forest (southern boundary). Survival rates of 20 bruchids from each location were observed for two hours using 0.1 ml, 0.2 ml, 0.3 ml, 0.4 ml and 0.5 ml of pirimiphos methyl (Actellic ® 25EC). Two age groups of the bruchids (1-day old and 7-day old adults) were treated separately to study the age influence on their resistance and samples were replicated three times. ...
