贵州省仁怀市昆虫资源调查

Investigation of Insect Resource in Renhuai City,Guizhou Province

通过对仁怀市的昆虫开展调查,明确仁怀市的昆虫多样性和种群分布,旨在为该地区昆虫资源的保护与利用提供理论依据。采用网捕法和灯诱法调查该地区昆虫的种类和数量,结果表明:(1)该调查区共鉴定出昆虫20目224科590属800种,其中3个目种类最多,分别为鞘翅目61科147属207种、鳞翅目38科150属191种和半翅目47科141属178种;(2)常见7个昆虫目中,Shannon-Wiener多样性指数、Pielou均匀度指数和Simpson优势度指数3个多样性指数无显著差异,Margalef丰富度指数存在显著差异,鳞翅目昆虫的丰富度指数高达184.4498;该研究为仁怀市的昆虫物种多样性提供了一定参考,也为昆虫资源的保护和利用奠定了科学资料。

In order to provide theoretical basis for the protection and utilization of insect resources in Renhuai City,the insect diversity and population distribution in this area were clarified through the field investigation The net-trap and light trap methods were used to survey the species and quantity of insects in the area.The results showed that:(1)A total of 800 species of insects belongling to 590 genera,224 families,20 orders were collected and identified from investigation area,including 61 families,147 genera and 207 species in Coleoptera,38 families,150 genera and 191 species in Lepidoptera,and 47 families,141 genera and 178 species in Hemiptera.(2)There was no significant difference among the 7 common insect orders in the Shannon-Wiener,Pielou and Simpson diversity index,but that was significant differences in Margalef index,and the richness index of Lepidoptera was as high as 184.4498.This study provided some references for the species diversity of insects in Renhuai City,and also laid a scientific foundation for the protection and utilization of insect resources.
