The melon thrips (Thrips palmi) is a serious insect pest of vegetables and ornamental plants. To control and monitor this thrips, blue traps are widely used. We previously reported that irradiation of cucumber plants with red light-emitting diodes (660 nm) causes T. palmi to avoid the plants. Here, we evaluated the responses of T. palmi adults to a cucumber plant in an experimental arena with either a transparent sticky trap or a blue sticky trap, without or with illumination by a red LED panel. When T. palmi were introduced into the arena, the number of thrips attracted to the plant was lowest in treatments using the red light and blue trap. On the other hand, when T. palmi were inoculated on plants first, most thrips stayed put on the plants. Placing both red LEDs and blue sticky traps in greenhouses before the thrips invade the greenhouse from the outside might effectively control T. palmi.
瓜蓟马（Thrips palmi）是蔬菜和观赏植物的严重虫害。为了控制和监测这种蓟马，广泛使用蓝色诱虫板。我们之前报道过，用红色发光二极管（660nm）照射黄瓜植株会导致瓜蓟马躲避植株。在这里，我们评估了成虫在有透明粘性诱虫板或蓝色粘性诱虫板的实验场中对黄瓜植株的反应，有无红色 LED 板照明。当瓜蓟马被引入竞技场时，在使用红光和蓝色诱虫板的处理中，吸引蓟马的数量最低。另一方面，当瓜蓟马首先接种在植物上时，大多数蓟马留在植物上。在瓜蓟马从外部入侵温室之前，在温室中同时放置红色 LED 和蓝色粘性诱虫板可能可以有效控制瓜蓟马。
