2016年4月12-18日调查了陕西省渭南市果园节肢动物多样性,结果显示,果园节肢动物504头,隶属4纲、12目、34科、54种.果园的Shannon-Wiener多样性指数(H′)为3.49、Shannon均匀度指数(J)为13.93、Berger-Parker(D)优势度指数为0.083.优势类群是鞘翅目、半翅目、膜翅目,这三个目占总捕获量的比例最大,物种数量比例分别为38.29%、18.65%和18.45%.植食性节肢动物28种,共343头;捕食性节肢动物18种,共120头;腐食性及中性节肢动物6种,共31头,它们的物种数量占总捕获量的比例依次为53.85%、34.62%和11.54%.调查结果可为开展关中经济地区果园节肢动物方面的研究提供基础资料.%An investigation on the arthropod diversity in orchard of Weinan was conducted on April 12-18,2016. The results showed that there were 504 orchard arthropods, belonging to 54 species,34 families,12 orders in 4 classes. The Shannon-Wiener diversity index (H′), Shannon evenness index (J), Berger-Parker dominance index (D) value of orchard were 3.49, 13.93,0.083 respectively. The dominant groups were Coleoptera,Hemiptera, Hymenoptera,they occupied the largest proportion of total capture and accounted for 38.29%,18.65% and 18.45% of species number respectively. There were 28 kinds of her-bivorous arthropods,18 kinds of predatory arthropods, and 6 kinds of saprophagous and neutral arthropods,amounting to 343,120,and 31 heads respectively. The proportion of their species accounted for 53.85%, 34.62% and 11.54% of total catch in turn. The results may provide basic information for the research on orchard arthropod in Guanzhong economic area.
