Screening different varieties of okra [Abelmoschus esculentus (L.) Moench] against sucking insect pests

Author(s): Jitendra Nagar, SK Khinchi, KC Kumawat and Anita Sharma
Abstract: Out of nine varieties of okra, Abelmoschus esculentus (L.) Moench screened against the sucking insect pests [leaf hopper, Amrasca biguttula biguttula (Ishida); whitefly, Bemisia tabaci (Genn.)], 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 IIVR-11and IIVR-10 were found as least susceptible, varieties Hisar Unnat, Pusa A-4, Versa Uphar, Pusa Sawani, Aparajita and Ankur-40 as moderately susceptible; and variety Anika as highly susceptible to the leaf hopper. The varieties IIVR-11 and IIVR-10 were found as least susceptible, varieties Hisar Unnat, Pusa A-4, Versa Uphar, Pusa Sawani and Aparajita as moderately susceptible; and varieties Ankur-40 and Anika as highly susceptible to the whitefly infestation. The morphological characters, viz., plant height and days to initiation of flowering of different varieties of okra had positive significant effect on the infestation of leaf hopper and whitefly. Length and width of fruits had significant positive effect on infestation of leaf hopper while non-significant effect on infestation of whitefly. Hairiness (on shoot, leaf and fruit) and number of fruits per plant had negative significant effect on the infestation of leaf hopper and whitefly.
