| Research Abstract |
Pirate bugs, Orius spp. are promising natural enemies of thrips which have developed high resistance to many insecticides. In the present study, effects of pearl body secreted by okra on the survival and reproduction of Orius spp. adults and nymphs were examined. Early nymphs fed on pearl body could survive but not grown to adults. However, nymphs and adults survived at extremely lower prey density by feeding on the pearl body. Okra planting in eggplant fields enable Orius populations to persist sustainable, leading to a good and stable control of thrips in eggplant open-fields.
