Bruchidius atrolineatus (Pic) is the main pest of cowpea in cultivation and at the start of storage. In this study, the effect of mint leaf persistence was investigated on adult mortality of B. atrolineatus. To do this, a variable number of after glow is tested on adults with a negative control for each experiment. Analysis of the results shows over 80% of adults die using only 3g of afterglow compared to only 5% in the control. By varying the amount of afterglow, all results showed that afterglow seemed to be more effective than during the first three days of the experiment. For the shelf life and when the same amount of the number of persistence is renewed every two days, the mortality of adults of B. atrolineatus seems to be greater and spread over time. These results are necessary indicators for the technical services with a view to implementing alternative control strategies.
