Abstract

The Laboratory study was administrated to evaluate the toxic and latent effect of, fenpyroximate, Lufenuron, Spinosad, and Mineral oil against egg and adult stages of, Tetranychus urticae. The results showed that fenpyroximate showed the very best toxicity, flowed by Lufenuron, Spinosad and kz-oil to egg and adult stages of Tetranychus urticae with LC50 0.86, 1.28, 4.41 and 218.79 ppm to eggs and 1.44, 2.42, 6.72 and 462.18 ppm to adult. The tested compounds reduced egg deposition and egg hatchability of Tetranychus urticae compared to control treatments. Lufenuron, fenpyroximate were the foremost effective compound against Tetranychus urticae with relevance to deposition and egg hatchability while Spinosad and Mineral oil was the smallest amount effective one.
