摘要
根据地理地貌、气候条件、农作物区划及农业昆虫的种类构成，发生危害特点，拟把广西农业昆虫的地理分布区划为三区：Ⅰ．桂南热带性种类发生危害区，Ⅱ．桂中南亚热带种类发生危害区，Ⅲ．桂东北中亚热带种类发生危害区。桂南区和桂中区又各分为东西亚区。根据农业昆虫的区系和发生危害特点，提出了各区域的害虫防治策略。
According to the diversity of geography,climate,crops and the faunal structure,geographic distribution, occurrence of agricultural insects, the Gangxi agricultural insect geographic division should be divided into 3 zones proposed.They are:Ⅰ.the tropical(south of Guangxi),Ⅱ.the south subtropical(central Guangxi) and,Ⅲ.the middle subtropical(nottheast of Guangxi)insect pests occurring zones.The first one and the second one can also be divided into west subregion and east subregion,respectively.The regional tactices for controlling the insect pests in Guangxi are suggested.
