Abstract
The aim of this study was carried out to determine the efficacy of six insecticides, acetamiprid, imidacloprid, thiamethoxam, thiacloprid, etofenprox and pirimiphos methyl  for controlling some sucking pests; the sweet potato whitefly, Bemisia tabaci (Genn.) and the two spotted spider mite, Tetranychus urticae Koch on tomato and strawberry during 2012 and 2013 seasons. Data showed that the highest general mean reduction percentages of two seasons against B. tabaci adults and nymphs on tomato were obtained by pirimiphos methyl and thiamethoxam, while the lowest effects were obtained by thiacloprid and etofenprox. Concerning the effect of tested insecticides on strawberry, thiamethoxam recorded the highest effect against both B. tabaci adults and nymphs, whereas thiacloprid showed the lowest effect. On the other hand, there were significant differences in T. urticae population on tomato and strawberry between treatments and check after spraying. Data showed that the most effective compound of the experiment was pirimiphos methyl, while the lowest effect was obtained with thiacloprid on tomato. Acetamiprid recorded the highest effective compound of the experiment, whereas imidacloprid gave the lowest effect on strawberry in two seasons of the study.
