Molecular Characterization of Whitefly Bemisia Tabaci (genn.) and Development of IPM Module Against Chili Leaf Curl Complex

Molecular identification/characterization of Bemisia tabaci (Genn.) collected across five agroecological zones of West Bengal, India revealed that it resembles genetic group Q. Seed treatment with thiamethoxam 70WS 3 g/kg seed incorporated with seedling treatment with acetamiprid 20SP @ 1g/l, seedling rising under insect proof net and border netting with insect proof net showed efficacy with reducing the occurrence and dispersal of thrips Scirtothrips dorsalis Hood, mite Polyphagotersonemus latus and whiteflies B. tabaci; while their least incidence was observed with IPM module (integration of seed treatment, seedling treatment, seedling raising under insect proof net, border netting technology, installation of yellow sticky trap and need based spot application of spiromesifen and diafenthiuron), with 92.97, 82.68 and 72.97% reduction, respectively; and 98.56% reduction of chilli leaf curl virus (CLCV) incidence could be obtained through IPM with maximum yield of green chili (1.66 t/ha). Panchagavya, dasaparni and bhramvastra appeared as potent biopesticides in reducing the CLCV causative agents.
