瓜蓟马（Thrips palmiKarny）是一种危害严重的农业害虫。以前的研究表明，红光减少了温室中棕榈蓟马的数量。为了了解红光如何影响T。帕尔米，我们研究了在自然光或荧光（正常白光）光的环境中用红色发光二极管面板（660 nm）照射的宿主植物的行为反应。当T。在实验竞技场中，我们发现红光照射的植物比正常光照下的植物吸引较少的个体。然后，我们使用一个绿色的粘性陷阱，以排除嗅觉和视觉刺激与宿主植物，以测试二元选择行为在T.帕尔米。用红光照射的绿色粘性陷阱吸引的蓟马数量约为没有红光照射的一半。这是第一项研究表明，增加红光可以改变昆虫的行为，导致在正常照明环境中避免绿色目标。
The melon thrips,Thrips palmiKarny (Thysanoptera: Thripidae), is a serious agricultural pest of many crops. Previous studies have shown that red light decreases the number ofThrips palmiin greenhouses. In order to understand how red light affectsT. palmi, we examined the behavioral responses to host plants that were irradiated with a red light-emitting diode panel (660 nm) in an environment with natural or fluorescent (normal-white) light. WhenT. palmiwere allowed to move freely around in the experimental arena, we found that fewer individuals were attracted to plants irradiated by red light than to plants under normal light illumination. We then used a sticky trap of green coloration to exclude olfactory and visual stimuli associated with the host plants in order to test binary choice behavior inT. palmi. The number of thrips attracted to the green sticky trap irradiated with red light was approximately half of that without red light irradiation. This is the first study to show that an addition of red light can change the behavior of insects, leading to an avoidance of green targets in an environment of normal illumination.
