Studies were conducted to evaluate the biological activity of seed oil extract of C. colocynthis at rate of 10 , 15 , 20 % against Tetranychus urticae ( Koch ) , Bemisia tabaci and Myzus persicae Suiz. Result showed that all concentrations were effectiveness in controlling Tetranychus urticae , Bemisia tabaci and Myzus persicae in the laboratory . Mortality percents were 30 , 100 , 100 and 62.5 , 71.2 , 89.5 and 91 , 93.4 , 100 % for the pests at three rates respectively . Field studies indicated that the rate 15 % was effectiveness in controlling T. urticae with mortality of 99.7 % after three days of application . The realability of using the extract in the management practices against the intended pests was discussed.
