    摘要:

    2005和2006年,在云南西部瑞丽、潞江坝、六库、保山、大理5个地区,采用信息素引诱法及被害瓜果内实蝇收集法对5个地区实蝇多样性进行分析。结果表明,5个地区实蝇丰富度的发生模式明显分为2种类型:瑞丽和潞江坝实蝇全年发生;六库、保山和大理实蝇季节性发生;瑞丽的实蝇种类丰富度最高,有20种,其次是潞江坝,11种,而保山、大理的实蝇种类丰富度低,分别为4种和3种;该区域实蝇优势种为桔小实蝇(Bactrocera dorsalis)和南亚果实蝇(B. tau);2年实蝇多样性指数均以六库最低,以潞江坝最高。各地实蝇种类相似性变化较大, 相似性系数在0.15~1.00 之间。结果为了解云南西部实蝇种类分布以及预防实蝇危害提供了基础数据。

    Abstract:

    Fruit fly species were collected through methyl eugenol-baited and cue-baited traps and from attacked fruits and melons in 2005 and 2006 at Ruili, Lujiangba, Liuku, Baoshan, and Dali in the western Yunnan. The species composition and diversity of fruit flies, and species similarity were studied, and cluster analysis was conducted. There were two occurrence patterns of the fruit fly species. One was year around occurrence at Ruili and Lujiangba, the other was seasonal occurrence at Liuku, Baoshan and Dali. The dominant species were Bactrocera dorsalis and B. tau in the five regions. The highest species richness of fruit flies was found at Ruili with 20 species, following at Lujiangba with 11 species. The lowest species richness was found at Dali with only 3 species. The lowest diversity index was found at Liuku, and the highest at Lujiangba. The similarity index of species ranged from 0.15 to 1.00. The results provided fundamental data for understanding distributions and diversity of fruit fly species and preventing from damage of the fruit flies in the western Yunnan, China.
