| Abstract | ||||
| In the laboratory and field experiments carried out to investigate the efficiency of some acetone and methanol plant extracts, against Tetranychus urticae Koch on kidney bean and cucumber plants. The results were recorded after 3 days for laboratory treatment. The obtained data indicated that, the acetone Egyptian henbane extract was the high toxic to the females of T. urticae with mortality rate 91.21%, followed by methanol thorn apple extract with mortality rate 85.71%, acetone winter cherry extract with mortality rate 83.52%, and methanol neem extract with mortality rate 75.82%. While common milkweed and sweet clover extract gave a weak mortality rate when extracted by both solvents. However, in the field experiment the plant extracts which extracted by methanol at a concentration 4%, recorded a high reduction at rang of (67.95-79.47%) on kidney bean while, on cucumber was between (74.51-80.16%).These resultssuggest that plant extracts couldbe incorporatedin integrated pest management(IPM)programs of T. urticae on Kidney bean and cucumber plants. | ||||
