兼长角纹石蛾幼虫适宜生存于水质优良且流速较快的水体环境 .该石蛾每年在湖南柘溪水库大坝之下几km范围大量发生 .对于水流速度较快的主干河流来说 ,采用常规剧毒农用杀虫剂对石蛾幼虫进行防治是不可取的 ,采用其它长期污染水质的办法控制石蛾幼虫的发生也不符合环境保护原则 .侧重报道如何选用对环境极少污染的酸碱盐及敌百虫等药物 ,当电站关闸停机 ,河床断流后 ,迅速杀灭石蛾幼虫的化学防治方法
The larvae of Helicoverpa armigera are suitable for living in the water environment with good water quality and fast flow velocity.The caducous moths occur in large quantities in the range of a few km below the Suixi reservoir dam in Hunan each year.In the case of the main rivers whose water flow is faster, Conventional highly toxic agricultural insecticides on the prevention and treatment of caterpillar moth larvae is not desirable, the use of other long-term pollution of water quality control of the occurrence of caterpillar moth larvae also do not meet the principles of environmental protection, focusing on how to use the environment rarely contaminated acid Alkali salts and trichlorfon and other drugs, when the shut-off shut down the power plant, river bed cut-off, the rapid killing of the chemical control methods of caterpillar moth larvae
