摘要: The two-spotted spider mite, Tetranychus urticae Koch (Tetranychidae), is a pest of agricultural crops that could potentially be controlled by the predatory mite Neoseiulus pseudolongispinosus (Xin, Liang and Ke) (Phytoseiidae). This study investigated the development, fecundity and population density of these two mite species on three different species of bean (Phaseolus lunatus L., Lablab purpureus [L.] and Phaseolus vulgaris L. [Papilionaceae: Leguminosae]). The morphological characteristics of the host plants, including leaf area, thickness and hairiness, main stem diameter and plant height affected development rate, fecundity and population density of T. urticae and also the searching success and abundance of the predatory species, N. pseudolongispinosus. L. purpureus was found to be a superior host plant for both predator and prey species. These findings emphasize the importance of host plant characteristics on the performance of species used for biological control.
