摘　　要：为探明贵州省不同生态环境水稻3个主要生育期稻田寄生蜂物种组成的异同及多样性特点,采用田间调查的方法在具有不同代表性的4个区域(贵州省榕江县车江乡、绥阳县洋川镇、贵阳市花溪区石板镇和六枝特区平寨镇)进行了调查研究。结果表明:采集到水稻寄生蜂标本5 222号,隶属23科123属224种;各地稻田寄生蜂个体数和丰富度的最高时期出现在乳熟期,除榕江县车江乡稻田寄生蜂的优势度最高时期出现在乳熟期外,其余各地的多样性指数、优势度和均匀度的最高时期均出现在抽穗期-开花期。稻田寄生蜂的多样性取决于其物种数及物种个体数的分布情况。Studying on composition of paddy parasitic wasp species in four different rice areas（Chejiang Rongjiang,Yangchuan Suiyang,Shiban Guiyang and Pingzhai Liuzhi）in order to probe into the similarities and differences of wasp species diversity in three different rice growing stages.Results：Through two years of investigation,5 222 specimens were collected in three growth stages of rice in total.224 species,belonging to 123 genera,23families;Among the three rice growth stages,period of the highest individual number,highest index of richness,diversity,dominance and uniformity were milky stage,milky stage,heading-flowering stage,heading-flowering stage（milky stage in Chejiang Rongjiang）and heading-flowering stage.The diversity index of parasitic wasps in paddy field depends on individual quantity and the field distribution of species.
