Investigation of Host Preference for Ten Leguminous Plants and Selection of a Trap Plant for Control of Tetranychus urticae (Acari: Tetranychidae)
Abstract
The two-spotted spider mite, Tetranychus urticae Koch, is a major pest of greenhouse strawberry. T. urticae rapidly develops resistance to acaricides due to its short life cycle and continuous exposure to these chemicals. Therefore, new pest management strategies, such as trap plants, are needed for sustainable control of T. urticae. In this study, we evaluated the host acceptance and preference of T. urticae for ten leguminous plant species to select trap plants in the laboratory. As a result, nine leguminous plant species as adzuki bean, black soybean, brown soybean, fava bean, kidney bean, mung bean, pea, peanut, and sword bean, except chickpea, were highly accepted by T. urticae compared to the control (acrylic board) in two-choice tests. Among the nine plant species, kidney bean, black soybean, and adzuki bean showed higher preference by T. urticae than the other plant species in multiple-choice tests. These three selected plants also showed preference under dark conditions, and particularly kidney bean was 3 times more effective in attracting T. urticae and inducing oviposition than strawberry. Additionally, kidney bean seedlings with a height of 300 mm showed a higher preference of T. urticae than those with a height of 150 mm. The results of this study indicate that kidney bean seedlings have the potential to serve as trap plants for T. urticae.
