利用趋光习性防治兼长角纹石蛾

为综合治理湖南省柘溪水电站夏秋季节大量发生的造成严重环境污染的毛翅目昆虫兼长角纹石蛾，于1997－1999年对该虫进行了防治研究。针对该石蛾成虫习惯在相对湿度较大的沿河两岸活动，且在夜晚有明显的趋光性，其成虫对蓝光最为敏感等特性，1999年采用5盏蓝光灯，沿河设置一定数量的抽风漏斗式诱蛾装置诱杀，共诱集到该石蛾成虫8960．5kg，从而有效控制了该石蛾的大量发生。

On Physical Control of Amphipsyche proluta MacLachlan

At Zhexi Reservoir of Hunan Province, a species of insects of Trichoptera that named Amphipsyche proluta MacLachlan arise in great quantities (over 10 tons or over 1 000 millions of individual) from May to October every year, and they pollute the power station's living and producing conditions seriously. Usually the adults of this insect obviously have the tendency towards light at night.The experiments show that the moth are most sensitive to blue light.
