【目的】本研究旨在探索麦红吸浆虫Sitodiplosis mosellana对线偏振光的趋光效果。【方法】在室内采用自行设计的Y-型管装置,测试了麦红吸浆虫成虫对线偏振光与非偏振光的选择差异,并利用线偏振光诱捕装置进行了田间对比试验。【结果】结果显示,麦红吸浆虫成虫对线偏振光与非偏振光的趋光选择率分别为47.23%和20.31%,且二者之间差异显著;田间设置线偏振光与非偏振光紫外灯对麦红吸浆虫成虫的诱集量分别为:水平线偏振光(60.20)>垂直线偏振光(37.60)>非偏振光(25.60),且水平线偏振光与非偏振光源对麦红吸浆虫的诱集量具有显著差异。【结论】麦红吸浆虫对线偏振光具有较强的偏好性;水平线偏振紫外光诱捕装置与非偏振相比,对麦红吸浆虫有较强的诱集效果。
【Objective】 The purpose of this study was to investigate the phototaxis effect of Sitodiplosis mosellana on linearly polarized light. 【Method】 The experiment was conducted to determine the difference of linear polarized light and unpolarized light between adults and adults using the Y-tube device designed by ourselves. The field experiments were carried out by using linear polarized light trapping device. 【Result】 The results showed that the phototrophic selectivity of adults and adults of the imazethapyr were 47.23% and 20.31% respectively, and there was a significant difference between them. In the field, linear and non-polarized ultraviolet lamps The amount of trapped adults of Myzus persicae were as follows: horizontal linearly polarized light (60.20)> vertical linearly polarized light (37.60)> unpolarized light (25.60) There are significant differences. 【Conclusion】 Midgut albopictus has a strong preference for linearly polarized light. Compared with unpolarized light, horizontal linearly polarized ultraviolet light trapping device has a stronger trapping effect on Midazolam.
