Abstract : Laboratory studies were conducted to determine the feeding potential of the cashew stem and root borer, Plocaederus ferrugineus, larvae on 5 different hosts, i.e. cashew, drumstick, silk cotton, mango and jackfruit. Results showed that cashew was the more preferred host than drumstick and silk cotton. The growth rate (GR) was highest (0.025) in drumstick, followed by silk cotton (0.019) and cashew (0.018). Likewise, the duration of larvae (fourth instar) was shorter in drumstick (58.0 days), followed by silk cotton (66.0 days) and cashew (72.0 days). Mango and jackfruit were not preferred as hosts.
