海南南湾自然保护区蝗虫多样性的研究

BIODIVERSITY OF ACRIDOIDEA AT NANWAN NATURE RESERVE, HAINAN

海南南湾自然保护区共记录蝗虫5科23属26种．以隆x小车蝗Oedaleusabruptus（Thunberg）、花胫绿纹蝗Aiolopustamulus（Fabricius）、疣蝗Trilophidaeannulata（Thunberg）、威廉剑角蝗AcridawillemseiDirsh为优势种。当地一年四季都有蝗虫在活动，以夏季的种类和数量最多，春季次之，冬季最少，南湾蝗虫可以分成三种主要群落类型，南湾蝗虫的Simpeon指数λ＝0.089，PIE指数PIE＝0.911，Shannon－Wiener指数H'＝2．595，Pielou指数J＝0．852，Whittaker指数Bws＝4．15。

In Nanwan Nature Reserve of Hainan province, 26 species of Aeridoidea were recorded,they belonged to 5 families and 23 genera. The numbers of genera and species of Catantopidaewere the largest (11 genera, 12 species ). Oedaleus abruptus (Thunberg ), Aiolopus tamulus(Fabricius), Trilophidae annulata (Thunberg) and Acrida willemsei Dirsh were superior in number.In the nature reserve the insects of Acridoidea could be found all the year round. The numbers ofspecies and individuals be found were: the largest in summer. the smallest in winter, and middlein spring. The insects could be distinguished into 3 types of community approximately. Severalbiediversity indexes were: Simpson index λ = 0. 089, PIE index PIE=0. 911, Shannon-Wienerindex H' = 2. 595, Pielou index J' = 0. 852, Whittaker index Bws= 4. 15.
