| 摘 要： | 2005-2006年在陕西黄土高原苹果优生区黄陵县对苹果园的草蛉资源调查的研究结果表明:该地区果园有9种草蛉,以中华草蛉、丽草蛉和大草蛉为优势种;不同生境类型的果园对草蛉群落多样性影响显著;果园周边天然草地上的草蛉群落多样性指数最高,周边菜地上的草蛉群落多样性指数最低;在夏季草蛉群落的多样性指数最高。

| Abstract: | Shannon-rWiener''s diversity index(H''),Pielou''s evenness(E),Sunpson''s domroance(C) and H urlbert''s PIE were calculated for the grnlac,wing communities in the orchards of loess plateau area in Shaanxi province.The results showed that the green lac,wing community consists of 9 sp,cies in all,dominant species are Chrysopa septempunc,C.forrno.sa and C.sinica; the diversity index of green lacewing communities in natural grassland is the highest; the diversity index of green lacewing communities gets the highest in summer,and then it begins to decline. |
