茶园LED诱虫灯的研发和应用现状

LED Lamps for Insect Trapping at Tea Plantations

诱虫灯是一项较传统但不断创新的田间物理防治农业害虫技术。频振式诱虫灯曾因其诱虫效率高而广泛应用,但也造成天敌昆虫的无差别诱杀。而LED诱虫灯却是一种可调控光波长的新型灯诱技术,现已在茶园中广泛使用,可显著减少化学杀虫剂的施用,进而提升茶叶品质。本文总结了茶园中LED诱虫灯的研发和应用现状,展望了该技术的优化方向,如调节光源波长以提高靶向性,调节光源强度以提高引诱力,科学设置工作模式以提高利用率,应对环境因素以提高效益等,以期为茶园LED诱虫灯的改进提供参考。

As an effective physical pest-control means,the use of lamps to trap pest insects in the field or greenhouses that grow crops has been a common practice for a long time.It continues to evolve as new technologies become available.Lamps that deliver light of fixed wavelength are widely applied.However,they tend to cause collateral casualties to natural predators while catching pests.Consequently,when light-emitting diode(LED)lamps of varied wavelengths came on the market,tea plantations began to be interested in the application as well.For the apparent advantages of reduction on chemical insecticide use and improvement on tea quality,this article summarizes the current status as well as future direction of development and applications of LED devices for our colleagues in the industry.The presentation was designed with an emphasized focus on the technical advances and method optimization in areas such as wavelength for precision targeted trapping,light intensity for attracting pest insects,lamp locations for effective trapping,and environmental design to maximize catches on pests with minimal number of predators.
