摘要
为研究信阳地区灯下昆虫种群群落结构,采用高空探照灯诱集昆虫对其种类进行鉴定,并对其群落结构进行分析。结果表明,共诱集到11目29131头昆虫,其中鳞翅目昆虫数量最多,占调查总数的30.80%,其次是鞘翅目、半翅目和直翅目,分别占调查总数的22.46%、20.81%和20.24%。本年度昆虫的种群发生量有3个高峰,分别在8月22日、9月2日和9月9日。物种丰富度有两个高峰,分别在8月7日和8月29日。Simpson-Wiener多样性指数(H')和均匀度指数(J)在7月31日均出现了一个高峰,表明信阳地区的昆虫多样性在此时最为丰富。信阳地区灯下昆虫类群发生量主要在8月份和9月份。
In order to study the community structure of insect population in Xinyang area,species andcommunity structure of insect under Xinyang was investigated and analyzed under searchlight.The results showed that 11 orders,29131 species were collected,among which Lepidoptera accounted for 30.80%,following by Coleoptera,Hemiptera and Orthoptera,accounting for 22.46%,20.81%and 20.24%,respectively.There were three peaks of insect population in this year,which were on August 22nd,September 2nd and September 9th,respectively.There were two peaks in species richness,on August 7th and August 29th,respectively.Simpson-Wiener diversity index(H')and evenness index(J)both showed a peak on July 31st,which indicated that the insect diversity in Xinyang was the richest at this time.The occurrence of insect groups under lights in Xinyang area mainly occurred in August and September.
