The experiment was carried out at the pest management laboratory of the Department of Crop, Soil and Pest Management under ambient laboratory conditions of 27±2 0 C temperature and 70±5% relative humidity. Each treatment was infested with 5 pairs of C. maculatus. The experiment was laid out in Completely Randomized Design with each treatment replicated three times. Mortality of cowpea beetles were assessed at 24, 48 and 72hours post treatment. Thereafter data were collected on oviposition, adult emergence, weevil perforation index and
