摘要
采取室内观察和室外调查相结合的方法,研究了美国白蛾在湖北孝感市的生物学特性。结果表明:美国白蛾在湖北孝感市1年发生3代,以蛹越冬,以幼虫危害多种树木。在此基础上,提出了检疫措施、人工防治、物理防治、生物防治、化学防治等综合防治技术措施。
The biological characteristics of Fall webworm(Hyphantria cunea)in Xiaogan City,Hubei Province were studied through indoor observation and outdoor investigation.The results showed that:Hyphantria cunea occurred in Xiaogan City,Hubei Province for 3 generations in1 year,overwintered with pupa,and damaged various trees with larvae.On the basis of the above,comprehensive technical measures such as quarantine measures,manual control,physical control,biological control,and chemical control were proposed.
