杨尺蠖(Apocheina cinerariusErschoff)是我县杨树的主要食叶幼虫,发生较普遍,危害严重,尤其在我县寅寺乡南北王林场更为严重,当杨树发芽时,初孵幼虫危害嫩芽,将芽吃光,造成幼树衰弱,形成小老树。为进一步摸清该虫的生物学特性,寻求有效的防治措施,我们于1985—1987年对该虫作了生物学特性观察和防治试验,现将结果整理如下。
Apocynaceae (Apocheina cinerariusErschoff) is the main leaf-eating larvae of poplar in our county, occurs more commonly and endangered, especially in the forest farm north and south of Yinxian Township in our county. When young poplar germinates, , The buds eaten, resulting in young trees weak, the formation of small trees. In order to further understand the biological characteristics of the insect and seek effective control measures, we conducted a biological observation and control test of the insect in 1985-1987, the results are summarized as follows.
