Abstract:

An experiment was conducted in the Field & Laboratory, Department of Agricultural Entomology, (BCKV), Nadia on the varietal preference of Whitefly Bemisia tabaci (Genn.) and Jassid Amrasca biguttula biguttula (Ishida) on okra Abelmoschus esculentus (L.) during the Kharif season of the year 2017. Among the Fifteen varieties considered none of the variety was found completely free from the infestation of leaf hopper and whitefly, although they differed significantly in their degree of damage and pest number to harbour. The varieties OH0, 5308, 1601 and Japanija were found as least susceptible, while variety Samrat was found to be highly susceptible to Whitefly and Jassid. Maximum pest population was found during third week of June i.e. 20th standard week of the year. The morphological characters, viz., length of fruit of different varieties of okra had positive significant effect on the infestation of Whitefly (0.54*) and Jassid (0.52*). Hairiness (on shoot, leaf) had negative significant effect on the infestation of whitefly and Jassid. Yield has significantly negative effect upon Whitefly (-0.83**) and Jassid (-0.62*) population build up. The maximum yield was recorded in the variety, OH05 (265q/ha). The YMV % and mean curl leaf/plant has significantly effect upon Whitefly (0.58*) and Jassid (0.78*) population build up.
