The aim of study to evaluate the effects of three different compounds including; Bensultap, Pirimophos- methyl, and Abamectin against major piercing sucking insect pests (Bemisia tabaci,Aphis craccicvora, Thrips tabaci, and Empoasca lypica) attacking kidney bean plants. Besides Assessment of the persistence of pesticide residues against the cotton leafworm Spodoptera littoralis Moreover, the side effects of pesticidal applications on morphological characters and chemical constituents of phaseolus vulgaris plants were also involved in the present study. The results showed that, the efficiency of the tested materials against sucking insects attacking kidney bean plants could be arranged in descending order as follows: Bensultap, Pirimiphos-methyl, and Abamectin.According to the obtained LT50 values, Bensultap had the longest residual effect followed by Pirimiphos-methyl and then ending with Abamectin at the two experimental periods, respectively
