Abstract
The obtained results of soil treatments against Psammotermes hypostoms (Desn.), indicated that, the three tested insecticides in different groups; chlorpyrifos, fipronil and cypermethrin were highly toxic in sub-surface layers of treated soil contains particle size of >850µm more than other particle sizes 425 and 250µm, respectively, and the fine soil was more safety to the ground water. Fipronil showed the highly toxic effect, followed by cypermethrin and chlorpyrifos, respectively. In coarse soil cypermethrin showed more toxic than other tested insecticides. The results of chemical determination of insecticides residues, data indicated that chlorpyrifos was more save for water table at all particle sizes followed by cypermethrin, while fipronil was the lower safety one, especially in soil particle sizes of 850 and 425µm, respectively. Generally the data of statistical analysis showed significant variations between all tested factors, (insecticides, particle sizes and depths of soil). with the variable, (mortality%).
