Abstract
White grubs <i>Adoretus</i><i> </i><i>emarginatus</i> Ohaus and <i>Heteronychus licas</i> Klug are beetles belonging to (Coleoptera: Scarabaeidae) sited among the serious subterranean pests of sugarcane <i>Succharum</i> <i>officinarum</i> L. (Graminae) in The Kenana Sugar Farm in Sudan. In this study, previous work on chemical control and population dynamic of the pest is reviewed. Field experiments and surveys were maintained for the two consecutive seasons ( ), in Kenana sugar farm targeting the white grubs as pests of the cane crop. Two concentrations from each of the three chemicals insecticides namely Dursban, Regent and Tafaban Chlorpyriphos, were tested for their efficacy against the white grubs. Tafaban 1L. /fed gave the best efficacy against the white grubs with average number of dead grubs (17.467± 1.4430).
