Abstract

Laboratory experiments evaluated the latent effects of lufenuron and rice bran extract on the newly hatched nymphs of Schistocerca gregaria produced from females who were treated as fifth nymphal instar with LC50 of each lufenuron and rice bran extract. Semithin sections of the newly hatchling showed great histological malformations in the structure of the brain, compound eyes, midgut, and hind leg muscles compared with control, these organs lost their normal structures, shapes, and functions. The tested compounds had serious extended histopathological effects, so they can be used to control S. gregaria as safe alternative agents to toxic synthetic pesticides.
