黑光灯诱杀农林害虫,是利用这些害虫具有“趋光性”的道理试验成功的。多数昆虫对3,300—4,000埃波长的紫外光敏感。因这部分紫外光对人是不可见的,所以称为“黑”光。我国目前使用的黑光灯的波长在3,600埃左右。试验证明,这种波长的光波对农林主要害虫的诱 Black light trapping agroforestry pests, is the use of these pests have “phototaxis ” the truth test success. Most insects are sensitive to UV light at 3,300-4,000 angstroms. Because this part of the UV is not visible to people, so called “black ” light. The black light currently used in our country has a wavelength of about 3,600 angstroms. Experiments show that this wavelength of light waves on the main pests of agriculture and forestry
