Abstract
Spotted pod borer, Maruca vitrata (Geyer) is a serious pest of legumes grains in tropics and subtropics, because of its extensive host range, destructiveness and distribution on pigeonpea, cowpea, mungbean, urdbean and field bean in southern zone of A.P. Maruca larvae feed on buds, flowers and pods by webbing them. This type of typical concealed feeding protects the larvae from natural enemies, human interventions and other adverse factors like insecticides (Sharma, 1998). In the present investigations, some newer insecticides were evaluated for their efficacy against M. vitrata in greengram. Lambda cyhalothrin in combination with Dichlorvos was found effective with 4.97% pod damage followed by Novaluron and Spinosad.
