桉蝙蛾Endoclyta signifier是严重危害速生桉主干的钻蛀性害虫,可导致林木衰弱、风折、甚至造成幼林报废,是当前影响桉树生产的主要虫害。查明桉蝙蛾原是博白乡土害虫,由于桉树的发展而转移危害速生桉。查明它在林区的发生和分布情况,是做好害虫防治工作的前提。在博白县调查的基础上,本文对桉蝙蛾的分布范围、速生桉品种与害虫发生关系、害虫自身生物学特点等讨论了发生和危害的特点,为防治桉蝙蛾提供依据。
Endoclyta signifier is a major pest that seriously damages the trunk of fast-growing eucalyptus. It can lead to the weakening, wind-breaking and even the abandonment of young forests. It is currently the main pest affecting eucalyptus production. Eucalyptus moths were identified as native pests, due to the development of eucalyptus and the transfer of fast-growing eucalyptus. Identification of its occurrence and distribution in the forest area is a prerequisite for pest control. Based on the investigation in Bobai County, this paper discusses the occurrence and the harm characteristics of eucalyptus moth, the relationship between fast-growing eucalyptus varieties and pests, the biological characteristics of pests and so on, and provides the basis for the prevention and control of eucalyptus moth.
