为了解贵州果蔬有害实蝇的种类及其多样性,2010—2011年在贵州德江、铜仁、凯里、都匀、贵阳和兴义共6个地区,采用性诱剂和食物引诱剂对有害果蔬实蝇进行系统监测和多样性分析。结果显示,6个地区2年共诱捕到果蔬有害实蝇14种,其中果实蝇属Bactrocera有11种,寡鬃实蝇属Dacus有3种;各监测地诱捕到实蝇种类数分别为德江3种、铜仁4种、凯里7种、都匀7种、贵阳11种、兴义12种;6地区共同优势种为桔小实蝇Bactrocera dorsalis、南亚果实蝇Bactrocera tau和具条实蝇Bactrocera scutellata,2010、2011年各监测点的相似性系数和多样性指数均存在差异,相似性系数、Simpson指数、Shannon指数和均匀性指数分别在0.25~0.80、0.11~0.68、0.28~1.25和0.18~0.62之间。研究表明,贵州实蝇种类丰富,不同地区优势种存在差异,不同种类为害差别大;各监测地区实蝇种群数量、丰富度、相似性系数和多样性指数整体上从东北向西南逐渐递增。
In order to understand the species and diversity of fruits and vegetables harmful to fruits and vegetables in Guizhou, 2010-2011 in the six districts of Guizhou Province, including Dejiang, Tongren, Carey, Duyun, Guiyang and Xingyi, using sex attractants and food attractants on harmful fruits and vegetables Fruit fly for system monitoring and diversity analysis. The results showed that there were 14 tragedy fruit flies in both regions in 2 years, of which 11 were Bactrocera and 3 were Dacus. The number of trapping fruit flies in each monitoring area was respectively Dejiang 3 7 species of Carey, 7 species of Duyun, 11 species of Guiyang and 12 species of Xingyi. The common dominant species in the 6 regions were Bactrocera dorsalis, Bactrocera tau and Bactrocera scutellata The similarity coefficient and diversity index of monitoring points in 2010 and 2011 are all different. The similarity coefficient, Simpson index, Shannon index and evenness index are respectively 0.25-0.80, 0.11-0.68, 0.28-1.25 and 0.18-0.62 between. The results showed that the species of fruit flies in Guizhou were rich, and the dominant species in different regions differed. The differences in the types of fruit flies were quite different. The population, abundance, similarity coefficient and diversity index of fruit flies in each monitoring area increased gradually from northeast to southwest.
