黑光灯能诱杀大量农林害虫,已被普遍应用于害虫测报和防治。但是,黑光灯是“敌我不分”的,在它诱杀害虫的同时,也能杀伤一些益虫,因此有人担心广泛使用黑光灯,不利于保护和利用天敌,对开展生物防治起着破坏作用。近两年,随着国际上植保科学技术的发展,又有人觉得,以黑光灯作为害虫测报的工具,已很落后,不再继续推广使用的价值。为了澄清这些问题,对黑光灯的作用作出较正确的评价,并探明一些合理利用黑光灯的具体措施,我们以我校农场和石家庄市近郊部分黑光灯1971～1978年诱到的虫情资料为主,进行了
Black light can lure a large number of agricultural and forestry pests, has been widely used in pests and forecasting. However, the black light is “enemy-indifferent”. When it lures and kills the pests, it can also kill some beneficial insects. Some people are worried that the widespread use of black light is not conducive to the protection and utilization of natural enemies, which may have a detrimental effect on biological control. In the past two years, with the development of science and technology in the field of plant protection in the world, some people think that the use of black light as a tool for measuring pests is far behind and will no longer continue to promote the value of its use. In order to clarify these issues, make a more accurate assessment of the role of black light, and to identify some of the specific measures to make reasonable use of black light, we take our school farms and Shijiazhuang suburbs black light part of the lure from 1971 to 1978 Mainly carried out
