一种毛翅目昆虫的生态治理研究

针对生活在水流速度较快的湖南省柘溪水电站一带河床大量发生的原双栖纹石蛾(Amphipsyche proluta)来说采用一般的防治措施都很难付诸实施，或者只能是治标，不能治本。经1997年至2000年的调查研究和试验分析得知人为去掉河底大型石块，加深河水深度，减缓流速，以破坏适宜于该石蛾幼虫生存的生态环境，引进生态致死因子，是从根本上杜绝该石蛾发生的较为理想的办法。

Studies on ecological management of a caddisfly (Trichoptera:Hydropsychidae)

In Zhexi power station of Hunan of China, a species of caddisfly named Amphipsyche proluta MacLachlan has arised in a great quantities (over 10 tons or 1000 millions individual) every year, and becomes a serious biological disaster. The ecological management of this insect are reported in this paper. Down from the dam of Zhexi reservoir, since the flowing speed of water on the river bed is faster, it is difficult to use common methods such as chemical, agricultural, physical and biological control methods to control this insect. Based on the investigation, experiments and analyses in 1997 to 2000, a better ecological measure was suggested to control the pest, which included digging the bigger stone on the river bed away, deepening the depth of water, and slowing down the flowing speed. It is expected that the environment in which the larvae live will be changed and this caddisfly will be controlled, ultimately a fundamental treatment to this insect will be given.
