Suppressive effect of Orius sp. (Hemiptera: Anthocoridae) on the population density of Thrips palmi Karny (Thysanoptera: Thripidae) in eggplant in an open field.

Abstract

Effect of predation by Orius sp. on the density of Thrips palmi KARNY on eggplant in an open field was estimated by the insecticidal check method. Orius sp. was controlled by application with fenthion (500ppm, emulsion). On eggplant untreated with fenthion, the population density of thrips reached high density levels in July and September.
