Effect of Abiotic Factors on the Incidence of Major Pests of Okra (Abelmoschus esculentus) and Natural Enemies


                                The present research was aimed to study the seasonal incidence of major sucking pests and the natural enemies on okra Abelmoschus esculentus under field condition at the Department of Agricultural Entomology, Agricultural College and Research Institute, Killikulam. The crop had revealed the incidence of sucking pests viz., aphid, jassid, whitefly, mites along with natural enemies like spiders and coccinellids. The incidence of jassid first commenced in 43rd SMW (0.30/3 leaves), aphids and whitefly in 44th SMW (0.10 and 0.35/3 leaves), mite was found in first SMW (25.53/cm2/leaf area). Earias infestation was found during 49th SMW (7.29 per cent). Natural enemies such coccinellids and spiders were observed during 45th (0.05/ plant) and 43rd SMW (0.05/plant) respectively.

Key words : Aphids, Jassids, Whitefly, Mites, Coccinellids, Spiders.
