Experimental area was carried out at faculty of Moshothor Agricultural, Banha University, Qalubiya Governorate, under open field conditions during April 2015 and 2016, respectively. This study aim to evaluating the efficacy of some plant extracts and chemical insecticides against sucking pests encompass (the whitefly, Bemisia tabaci, the thrips, Thrips tabaci, the aphid, Aphis gossypii in addition to the spider mite, Tetranychus urticae on Cucumber (Cucumis sativus L) and Economic feasibility to pests control under field condition. The results revealed that there are significant differences between using three systemic insecticides and five botanical oils on population density of whitefly, thrips and spider mite without aphid, wherever the tested compounds cause reduction to these pests. It is clear from the previous view that each of the treatment Final oil and garlic Oil extraction economically feasible compared to experiments either (thiamethoxam, imidacloprid , acetamiprid, rosemarie oil, sesame oil, lemon oil and control) as each pound investor in them achieves profit of each of them, respectively approximately 3.7, 2.9 pounds. Recommendation: the paper recommendation by using five botanical oils to reduce population of whitefly, thrips, aphid and red mite without any pesticides.
