Study on Injurious Insects Strage Grain Species Composition Hierarchy Autoeciousness Relationship

分析了害虫和天敌种群的动态趋势,表明寄生蜂复合种群数量消长与谷蠹和赤拟谷盗相近;分析了小麦散装粮堆储粮昆虫群落结构及演替特点,表明该群落由鞘翅目的玉米象、谷蠹、锯谷盗、赤拟谷盗、扁谷盗,膜翅目的米象小蜂、谷象小峰、谷虫小蜂,啮虫目的书虱,蜱螨目,鳞翅目的麦蛾组成。该群落在4-7月份昆虫种类和数量逐渐增加,7-9月份昆虫种类和数量达到最大,10-12月份昆虫种类和数量逐渐减少;2006年5、6间群落系数为0.6441,9、10月间群落系数为0.5910,2006年冬季和2007年春季群落系数为0.4516,月份、季节之间物种组成和数量相近。

This paper analysis pests and natural enemy species group moving tendency, make clear： parsitic bee complex species group anount growth and decline similar to Gu and chi Ni gu dan;analysis wheat bulk piles inseces community structure and successin feature, make clear that community make up of Qiao Chi mu（Yu Mi xiang Gu Ju Gu dan Chi Ni gu daoBian Gu dan）. Mo Chi mu（ Mi Xiag xiao feng Gu Xiang xiao feng Gu Chong xiao feng）, Nie Chong mu （Shu Sai）, pi Man mu , Lin Chi mu （MaiE）, Insects in that community were gradually increasing in April to July . Insect＇ s kinds and quan -tity reach to largest , in July toSeptenber, that gradually reduce ; community coefficient＇ C＇ was 0. 644in May to june 2006, community coefficient ＇ C＇ was 0. 5910in September to October 2006, Community coefficient＇ C＇ Was 0. 4561 in winter 2006 and in srping 2007. species hart and 1uantity is similar in months and seasons.
