Population control of small sucking insects has been challenging, and alternative control methods are constantly being sought. Visual traps have long been used to monitor and control pests. Colored sticky cards are widely used for diurnal pests, but their effects are influenced by environmental light conditions. Artificial light traps are mostly used for nocturnal pests. Here, we explored and evaluated light-emitting diode (LED) traps for the monitoring and control of small diurnal sucking insects using greenhouse tests targeting the greenhouse whitefly . We tested the trapping efficacy of the LED water pan trap, assessed the most attractive LED light and analyzed its efficacy under different weather conditions. The results showed that the LED water pan trap was too inefficient to be useful. Green LEDs were more attractive than yellow LEDs, UV LEDs and green-UV combinations. Regardless of sunny or cloudy conditions, the green LED trap caught more than twice the number of whiteflies than the yellow sticky card alone under summer shading conditions. Our study suggests that LED traps have a significant field application value in whitefly mass trapping and may also be efficient for other diurnal insects. The design of LED traps specific for diurnal insects is discussed.
对小型刺吸式昆虫进行种群控制一直具有挑战性，人们一直在不断寻找替代控制方法。视觉诱捕器长期以来一直用于监测和控制害虫。有色粘虫板广泛用于日间活动的害虫，但它们的效果会受到环境光照条件的影响。人工诱虫灯大多用于夜间活动的害虫。在此，我们通过以温室白粉虱为目标的温室试验，探索并评估了发光二极管（LED）诱捕器对小型日间刺吸式昆虫的监测和控制效果。我们测试了LED水盘诱捕器的诱捕效果，评估了最具吸引力的LED光，并分析了其在不同天气条件下的效果。结果表明，LED水盘诱捕器效率太低，没有实用价值。绿色LED比黄色LED、紫外LED以及绿色-紫外组合更具吸引力。在夏季遮荫条件下，无论晴天还是阴天，绿色LED诱捕器捕获的白粉虱数量比单独使用黄色粘虫板时多两倍以上。我们的研究表明，LED诱捕器在大规模诱捕白粉虱方面具有显著的田间应用价值，对其他日间活动的昆虫可能也有效。本文还讨论了针对日间活动昆虫的LED诱捕器的设计。
