| Abstract | ||
| Population density of some pests were studied on winter plantation of cucumber plant Cucumis sativus L. of 2019& 2020 seasons under greenhouse condition at Giza governorate, Egypt. Showed that significant difference between the weekly mean number of the pests under investigation. Bemisia tabaci (Genn.) was the most pests found in cucumber plants in two seasons. Evaluating the efficacy of some chemical insecticides and botanical oils were sprayed against sap-sucking pest, the whitefly, B. tabaci, on Cucumber plantin the greenhouse.The results revealed that there were significant differences between using three systemic insecticides and three botanical oils on the population density of B. tabaci cucumber plants were received two sprays of each tested treatment during the experimental period. Statistically, the percentage of reduction in B. tabaci counts between mentioned treatments was significant, whereas F value = 7.00** and L.S.D. = 1.96 during first spray and F value = 5.97** and L.S.D. = 2.33 for the second spray. Also the general means of reduction of two sprays, it is clear that Mospilan 20 SP (96%) appeared as the high mortality one in reducing rate of B. tabaci members followed significantly by Rosemarie oil (94.67%), Confidor 20% SL (93%), Garlic oil (92%), Actara (86%) and the lowest one Lemon oil (81.33%), respectively. | ||
