【摘要】 广西已定名的昆虫计有５９０１种，分别隶属２９目３３１科２８０６属。本文系从昆虫生态地理角度，论述了广西昆虫的区系结构、分布特点和规律，探讨了广西昆虫地理区划。在昆虫种类组成方面，鞘翅目、鳞翅目、膜翅目、半翅目、双翅目、同翅目、直翅目、等翅目等８个目的昆虫种数约占广西昆虫总种数的９４．３％。在区系结构方面，广西地处东洋区的北部，各区系成分的排序为：东洋区系种＞东洋—古北兼有种＞本区特有种＞世界广布种＞古北区系种。在东洋区系内，以中—缅亚区种明显大于马—菲亚区种。本文在详细论述昆虫生态地理分布特点及其规律的基础上，探讨了广西昆虫地理区划，大致将广西划分为５个昆虫治理开发区：Ⅰ桂东北区；Ⅱ桂西北区；Ⅲ桂东南区；Ⅳ桂西南区；Ⅴ桂南区。并对各区害虫发生与发展的预报、控制和有计划合理开发利用益虫提出了建议。更多还原

【Abstract】 The named insects in Guangxi total5901species which belong to29orders,331 families,2806genera.The faunal structure,characters of distribution and geographic division in Guangxi are discussed from the viewpoint of insect ecogeography.The species of8ciders which are Coleoptera,Leoidoptera,Hymenoptera,Hemiptera,Diptera,Homoptera,Orthoptera,Isoptera with great economic and healthful significane make up 94.3%of the total insects of Guangxi.Faunally,Guangxi is located on the north of the oriental region,in which the faunal elements from each region are in sequence as oriental region>oriental-palearctic region>local endemic> world-wide distribution>palearctic region.In the oriental region the elements of China-Burma area are obviously more than that of Malaya-Philppines area. Based on the characters of insect ecogeographical distribution and good for the control of pests and the utilization of benifical insects, the divition of Guangxi insects can be divided into 5 zones:ⅠGuangxi east-north zone,Ⅱ.Guangxi west-north zone,Ⅲ.Guangxi east-south zone,Ⅳ.Guangxi west -south znoe,Ⅴ Guangxi south zone.Some suggestions for controlling the happening and spreed of pests and reasonably utilizing the resources of benefical insects for each zone are given out.更多还原
