摘要：The current study was performed to assess the relative acaricidal toxicity of three miticides (abamectin, fenpyroximate, pyridaben). one insecticide (lambda-cyhalotluin), one mineral oil and one plant extract {Allium sativum) with different mode of actions against Tetranychus urticae under laboratory and field experiments. The results revealed that abamectin was the highest toxic compound followed by lambda-cyhalothrin with LC50 values of 0.15 and 16.48 ppm. respectively, while Allium sativum extract was the lowest one with LC50 value of 2869.49 ppm. All tested compounds reduced oviposition and hatchability of T. urticae compared to control. Abamcctin and X-cyhalothrin were the most effective compounds in reducing oviposition and hatcha-bility process of T. urticae, while Allium sativum extract had the least influence. Regarding the field experiment, abamcctin had the highest reduction per-ccnt (95%) again the T. urticae motile stages population. X-cyhalothrin exhibited remarkable acaricidal activity (88.58%) despite being an insecticide also Allium sativum extract achieved satisfied reduction percent (77.23%). Therefore, the role of Allium sativum extract should be considered in an integrated pest management program in order to reduce pesticide risks and costs. Further work is required to prepare Allium sativum extract in an appropriate formu-lation to enhance its activity.
