Abstract
Management of the whitefly, Bemisia tabaci (Gennadius) is considered one of the challenges to worldwide scientists and famers for achieving agricultural and environmental sustainability. In this work, we studied the effect of plant spacing, different combination of chemical fertilizers, treatment with potassium silicate, diurnal activity and some of chemical insecticides on the population density of B. tabaci on tomato plants under field conditions. The results showed that minimum population of whitefly nymphs were recorded to be per tomato leaves from those plots where maximum plant spacing (50 cm) was maintained. The results of effect of different rates of chemical fertilizers revealed that the treatment with nitrogen fertilizer was the most important factor affecting the population density of B. tabaci followed by potassium fertilizers and finally phosphorus fertilizers. The results also confirm that there are positive correlations between population densities of B. tabaci and levels of nitrogen fertilizer on tomato plants. The results concerning the diurnal activity of adults of B. tabaci clearly shown that there are significantly greater numbers of adults of B. tabaci were collected at 10:00 am and 11:00 am in summer and nili plantations, respectively compared with the other different times of the day. The tested insecticides against B. tabaci nymphs can be arranged as follows sulfoxaflor, thiamethoxam, acetamiprid, pyriproxphene, buprofezin and finally dinotefuran.
