一、黑光灯的诱虫效果利用昆虫的趋光性诱杀害虫,全国各地均有使用。1973年我场在7个生产队共装置20瓦黑光灯23盏诱杀地老虎成虫,收到了良好的效果。农六队在26号地同时放置黑光灯2盏,糖浆诱杀器80个(放置黑光灯的120亩地未放置糖浆诱杀器)。从3月20日开始到5月25日结束,80个糖浆诱杀器共捕成虫11,285头,2盏黑光灯共捕虫17,000余头,其中地老虎成虫12,200头,金龟(虫甲)、蝼蛄4,800余头。从经济效益上看,2盏黑光灯的造价与电费在使用期间约合100元,80个糖浆诱杀器约合400余元;从苗期被幼虫危害的结果看,放置黑光灯的地块比放置诱杀器的地块突出的轻;从诱虫种类上看,糖浆诱杀只能对一些趋化性强的鳞翅目害虫有效,一些鞘翅目的害虫就很难被诱杀,而黑光灯则能诱杀种类繁多的害虫。从农五队的
First, black light trap effect Insect phototaxis traps pests, are used throughout the country. In 1973, a total of 23 traps of 20-watt black light bulbs were installed at seven production teams in the field and received good results. Six farmers at the same time on the 26th place to place two black lights, syrup trapping 80 (120 acres of black light not placed syrup trap). From March 20 to the end of May 25, 80 syrup traps killed 11,285 adult beetles and a total of more than 17,000 heads of black spotlights, including 12,200 adult tiger beetles, more than 4,800 beetles head. From the economic point of view, 2 black light lamp cost and electricity during the use of about 100 yuan, 80 syrup trapping about 400 yuan; from the seedling damage by the results of larvae, the placement of black light than the land Turtles placed plots of light; From the species point of view, syrup trapping can only be effective for some chemotaxis lepidopteran pests, some coleopteran pests is very difficult to be trapping, and black light can trapping A wide variety of pests. From the five teams of farmers
