济南市郊春末夏初直翅目(Orthopteren)昆虫生态研究

THE INVESTIGATION OF ORTHOPTEREN ECOLOGICAL CHARACTER IN THE SUBURBS OF JINAN

本文系作者于1992年春末夏初对济南市郊直翅目昆虫群落进行调查研究的结果。讨论了直翅目昆虫成体及幼体与其选栖生境、生态习性(湿度)之间的关系及各个种的相对数量级。结果表明:春末夏初济南市郊直翅目昆虫计26种,分隶于2亚目,5总科,11科。其中以成体越冬计3种,多数种类以卵越冬,计23种;不同生境中同种直翅目昆虫幼体发育速度不一致,在济南市郊内表现为不同龄期的同一种类可同时捕到,共计8种其数量级为“极多”或“多”,可视为济南市部优势种,对其中能够侵入农田的大中型植食性种应进行必要的预报和防治。

This paper is the result of the author's investigation for Orthopteren communities in the suburbs of Jinan during the late spring and early summer in 1992.The relation be- tween the adults and larvae of Orthoptera and the choice of their habitats are discussed; The relative meristic level of each species is also discussed.The result shows that:there are 26 species of Orthoptera in the suburbs of Jinan during the late spring and early summer,which belong to 2 suborders,5 superfamilies,11 families.In them 3 species over winter in the form of adults,but most of the species over winter in the form of eggs. Thedevelopment speeds of the same species in different habitats are different.So the same species in different larvae can be obtained at the same time;According to the meris- tic level.there are 8 species which can be regarded as the dominant species,To that phy- tophagaus species which invade the farmland we should make necessary forecast and prevention.
