Heterorhabdilis indicus (RCR), AS A POTENTIAL BIOCONTROL AGENT OF GRAPE FLEA BEETLE, Sceledonta strigicollis M. (COLEOPTERA: CHRYSOMELIDAE)
Flea beetle, Sceierlonm srrfgicollis M. (Coleoptera: Chrysomelidae) is a serious pest in grape. Both adults and grubs are the damaging stages. Adults are small reddish brown in colour with six spots on the clytra. They often inﬂict serious damage to grapevine by feeding on leaves and tender buds. The female beetle oviposits on the bark or in the soil and eggs may be laid singly or in groups. The grubs hatch in four days and feed on roots. The grub pupates in an earthen shell and emerge as adult in about two weeks. The life cycle takes about two months (David and Kumaraswamy, 1991). It is often difﬁcult to control this pest with insecticides alone.
