摘　　要：为了摸清厚朴藤壶蚧生物学特性和发生规律,并寻找简便、经济、安全、有效的防治方法.采用标准株观察法和室内饲养法,研究其生物学特性和主要天敌的控害效果.采用标准地法研究不同栽培模式下藤壶蚧的危害程度.结果表明,藤壶蚧在恩施1 a发生1代,以受精雌成虫在枝干上越冬.主要天敌昆虫为寄生蜂类,该类寄生性天敌对藤壶蚧的发生有一定的控制作用.藤壶蚧的发生量与林分构成和自然环境有着密切的关系,厚朴与其它林木混交栽培的有虫株率远低于纯林、林作套种和林药套种等栽培模式.The purpose of this paper lies in finding out Asterococcus muratae Kuwana′s biological characteristics and its occuring laws,and looking for simple,economical,and effective control methods.By means of type strain observation method and indoor breeding method,its biological characteristics and main natural enemy′s control effect have been studied.What′s more,by way of simple plot method,Asterococcus muratae Kuwana′s hazard rating under different planting model has been researched.The results show that Asterococcus muratae Kuwana in Enshi occurs one generation per year and its mated adult females live through the winter on the limb.Parasitic wasps are the main natural enemy insects of Asterococcus muratae Kuwana,which have some controlling effect on the occurrence of it.The occurrence of Asterococcus muratae Kuwana is closely related to the structure of forest and environment.The strain rate of insects in Magnolia officinalis Rehd.et Wils and other trees mixed cultivation model is much lower than that of the pure forest model,relay cropping model of trees and crops,and relay cropping model of trees and medicine.
