Abstract:
Blackgram (Vigna mungo (L) Hepper) important pulse crop grown in Andhra Pradesh during rabi season. During the crop growth period various insect pests were observed among these insectpests Maruca vitrata caused more damage to the crop. This pest occurred on blackgram flowering stage to pod maturing stage during these crop M. vitrata causes more vulnerable damage to the crop. To know the intensity of incidence of M. vitrata survey was conducted during 15-10-2019 to 16-11-2019 in major blackgram growing areas of Andhra Pradesh. Incidence of M. vitrata varied from 29.09 to 71.52 per cent during rabi 2019-20. Majority of the farmers preferred PU-31, TBG-104, LBG-752 and TAU-1 varieties of blackgram for cultivation. Major blackgram growing areas of Andhra Pradesh farmers used chlorpyrifos, dichlorvos, thiodicarb, spinosad and chlorantraniliprole insecticides were used to managing the M. vitrata. Therophilus marucae larval parasitoid and Phanerotoma philippinensis egg-larval parasitoid of M. vitrata also observed during survey.
