摘　　要：瓜实蝇Zelugodacus cucurbitae和南亚果实蝇Zelugodacus tau是两种主要以葫芦科植物为寄主的瓜类实蝇,主要分布于我国南部和中部地区。在实际研究中发现南亚果实蝇和瓜实蝇分类地位、寄主范围和生活史相近,但分布区域可能存在差异。因此,采用性诱剂诱集法在全国14个省(自治区)对这两种实蝇的分布进行调查,结果显示南亚果实蝇在我国整个南部地区均有分布,瓜实蝇在我国的分布范围较小,主要分布于北纬25°以南。结合气候数据发现两种实蝇的分布范围基本上和各地年平均气温一致,瓜实蝇主要在年平均温度20℃以上的区域分布,南亚果实蝇则在年平均温度为15℃以上的区域均有分布。这种地理分布的差异可能是两种实蝇对气候环境和寄主植物适应能力不同所致。Zelugodacus cucurbitae and Zelugodacus tau are both cucurbit fruit flies, cucrbitaceous plants are mainly their hosts and distribute in southern and central China. In the actual study, we found that although the categorical position, host range and life history of the two flies are similar, the distribution areas may be different. In this study, the distribution of the two flies was investigated by sex attractant trapping in 14 provinces or autonomous regions in China, the results showed that Z. tau had distributed in the entire southern part of China while Z.cucurbitae only distributed in the south of 25°N. Combined with climate data, the distribution areas of the two flies was consistent with the average annual temperature and the Z. cucurbitaeis mainly distributed in an annual average temperature of 20℃ or above while the Z.tau was distributed over annual average temperature of 15℃ or above. This difference in latitudinal distribution was probably due to the different adaptation of the two flies to climate environment and host plants.
