杨树草履蚧发生特点及综合防治措施

Occurrence Characteristics and Control Measures of Drosicha corpulenta of the Poplar

草履蚧是鄂北襄州区杨树的主要害虫,自2009年首次在该区鄂西北防护林带发现以来,成自北向南初步蔓延趋势,该虫以刺吸树木的汁液为食,造成树木的衰弱甚至大片枯死,给林业生产带来不可估量的损失。本研究通过近几年实地观察、探索与实践,对草履蚧的形态特征、生活习性、危害特点进行了初步研究。通过提出加强虫害动态预报或预警,结合抚育管理,深翻林地,以破坏虫卵越夏和越冬场所,降低虫口密度,并采用阻隔带的绑贴物理防治方法配合化学防治等措施,取得了较好的防治效果。

Drosicha corpulenta is the main pests poplar in XiangZhou area northern of hubei for the first time found since 2009 in the region in north western of hubei selter belt, over the past few years, into a prelimi- nary spread trend from north to south, the insect feeds on sucking juice of trees, cause trees weak large die, even bring immeasurable losses to the production of forestry. Field observation, the exploration and practice by the study in recent years, the fulfillment of Drosicha corpulenta of morphological characteristics, life habit and damage characteristics is studied by strengthening the insect pests dynamic forecast and early warn- ing, combined with tending management, the commune of woodland, to destroy the eggs, the summer and winter, reducing population base; And adopt the barrier strip to stick the measures such as physical method with chemical control, good control effects have been achieved.
