Abstract

The current study was conducted in 2016 at two locations; Sakha and El-Riad, Kafr El-Sheikh governorate. Okra plants were sown at rice borders, canals and dikes at Sakha Agricultural Research Station, and as a solid crop at El-Riad in an area of 1000 m2. At both locations, okra plants were naturally infested by the leafhopper, Jacobiasca lybica (Bergevin and Zanon) (Hemiptera: Cicadellidae). To determine the parasitoids associated with the leafhopper, okra leaves having the eggs and nymphs of the leafhopper were picked up. The eggs and nymphs were excluded and incubated into petri dishes to be monitored for the possible emergence of parasitoids. One leafhopper nymph, collected from okra in rice fields, was found to be parasitized by Aphelopus sp. (Dryinidae: Hymenoptera). The leafhopper eggs collected from okra in rice fields or solid okra, hatched for four egg parasitoids. Three species; Anagrus spp., Anagrus atomus L., Stethynium sp. are belong to Mymaridae, and one parasitoid, Oligosita sp. belong to Tricogrammatidae. Anagrus parasitoids were the most abundant, while other parasitoids were found in low populations. To study the population fluctuations of the leafhopper adults and associated parasitoid, Anagrus spp., yellow sticky traps were fixed close to okra plants at both locations. J. lybica exhibited three peaks of occurrence at each location, while the parasitoid exhibited three peaks on okra surrounding rice fields, and two peaks on solid okra. It was concluded that okra plants in rice fields received higher numbers of parasitoids than solid okra.
