摘要
对栗链蚧在年周期中的发生发展与危害进行了调查研究。结果表明，栗链蚧在板栗树上扩散定殖的习性及分布与栗树枝条的分枝级次、皮层厚度、皮厚差和枝皮率等因素有不同程度的联系，从而为抗链蚧育种及栽培提供了一定的理论依据。
Occurrence, development and damage of Asterolecanium castaneae Russell on the Chinese chestnut in its yearly period were studied. The results showed that the habits of spread and propagation and distribution were related to the level of branch, the cortex thickness, drop of the thickness of each level and branch-cortex ratio. A theoretical foundation for breeding and cultivation of resistance chestnut was provided.
