摘要
为研究贺州市八步区林区灯下趋光性昆虫群落多样性,2015年5月至2016年5月,采用频振式杀虫灯进行了定点调查。结果表明,共诱捕到昆虫8目55科464种20 929头,其中鳞翅目(Lepidoptera)种类最多,占调查总种类数的75.87%。在鳞翅目中,诱捕的夜蛾科(Noctuidae)昆虫种类最多,相对多度为3.182。此外,发现Simpson指数(D)和Shannon指数(H')评价的贺州市八步区林区灯下趋光性昆虫种群发生量和物种丰富度的时间动态变化基本一致。
The ultraviolet light trap was used to investigate the community diversity of phototactic insects in Babu forest district of Hezhou city from May 2015 to May 2016. Results showed that total of 20 929 individuals,which belonged to 8 orders,55 families and 464 species,were captured. The order with the highest number was Lepidoptera, which accounted for 75.87%. The highest number of species was Noctuidae in Lepidoptera,which relative abundance was 3.182. Furthermore,no obvious changes of temporal dynamics of phototactic insects occurrence quantity and species richness were detected in Babu forest district of Hezhou city,which were evaluated by the Simpson(D) and Shannon Index(H').
