河南省蚧虫物种多样性及区系分布

Study on Species Diversity and Flora of Scale Insects in Henan Province

为了明确河南省蚧虫种群发生分布情况,2015—2017年对河南省蚧虫资源进行了调查研究。发现蚧虫10科71属145种;河南新记录属2个,为华粉蚧属(Sinococcus Wu)和蜡粉蚧属(Nipaecoccus Sulc);新记录种7个,分别为榆华粉蚧(Sinococcus ulmi Wu)、洛阳灰粉蚧(Dysmicoccus luoyangensis Li&Wu)、东亚灰粉蚧(Dysmicoccus dengwuensis Ferris)、广布安粉蚧(Antonina socialis Newstesd)、堆蜡粉蚧[Nipaecoccus vastalor(Maskell)]、樟白轮盾蚧(Aulacaspis yabunikkei Kuwana)、橙褐圆盾蚧(Chrysomphalus ficus Ashmead);优势种有12个。应用多样性指数对蚧虫种群进行分析,结果表明,Simpson指数(1-λ)介于0.693 9~0.892 1,Shannon-Wiener指数(H')介于0.764 6~1.039 0,均匀度(J)介于0.801 3~0.997 5,说明河南省蚧虫物种多样性丰富。区系组成分析结果显示,河南省蚧虫以东亚成分为主体,在地理区划上属古北界和东洋界交汇处。

To identify the population occurrence and distribution of scale insects in Henan province,from 2015 to 2017,a comprehensive and systematic investigation of the scale insects resources in Henan was carried out.145 species,71 genera and 10 families of scale insects were recorded.Two new genera records were Sinococcus Wu and Nipaecoccus Sulc,and seven new species records were Sinococcus ulmi Wu,Dysmicoccus luoyangensis Li&Wu,Dysmicoccus dengwuensis Ferris,Antonina socialis Newstesd,Nipaecoccus vastalor(Maskell),Aulacaspis yabunikkei Kuwana,Chrysomphalus ficus Ashmead in Henan province.Twelve dominant species were discovered.Diversity index was applied to analyze the diversity of scale insects species,and the results showed that the Simpson index(1-λ)was between 0.693 9 and 0.892 1,the Shannon-Wiener index(H′)was between 0.764 6 and 1.039 0,and the uniformity(J)was between 0.801 3 and 0.997 5,indicating that the species diversity of scale insects in Henan was abundant.The floristic analysis showed that the main part of scale insects in Henan was the East Asian component.The geographical division belonged to the confluence of the Palaearctic and the Oriental realms.
