为了探讨黑光灯对天敌昆虫的诱集情况,一九七五年我们在与汉阳县病虫测报站的紧密合作下,对水稻区进行了黑光灯下天敌昆虫的种类与数量的分析。试验所用黑光灯为20瓦交流灯管。黑光灯设置在稻田的开阔地带。点灯时间从五月十一日起到九月二十三日止,每天天黑前开灯,天亮后关灯。灯下诱到益虫十五科,共255种,总计虫数2,115,874头。详见表一。
In order to investigate the entrapment of natural enemies by black light, we conducted an analysis of the types and quantities of natural enemy insects under black light in the rice area in 1975, in close cooperation with the Hanyang County Pest and Disease Report Station. The black light used in the experiment was a 20 watt AC lamp. Black light set in the open area of rice fields. Turn on the lights from May 11 to September 23, turn on the lights every day before dark and turn off the lights after dawn. Fifty-five families of beneficial insects were induced under the light, a total of 255 species, a total of 2,115,874 insects. See Table 1 for details.
