The effect of plant distances on the Aleuroclava jasmini whitefly in the urban green area

Mulberry whitefly Aleuroclava jasmini sensu lato is the most important pest of trees in recent years in Tehran. Many plants have physiological and behavioral effects, such as repellency and deterioration of pests. Their effects were first evaluated with direct planting of plants Rosmarinus officinalis, Lavandula angustifolia and Pelargonum hortorum, and the method of establishment of Mulberry whitefly on them. In this research, with the release of Mulberry whitefly in wooden cages under controlled conditions for three days, the number of adult and egg whitefly laying on the leaves of the plants listed in a completely randomized design with four replications was investigated. Based on the results, the level of pest deposition on the tested plants was lower than the control. Also no egg was observed on any of the treatments. Therefore, these plants, in addition to preventing the laying of pests, have a good repellency and deterrent effect and can be used as a control solution in urban green space.
