| 本研究旨在通过实地调查番茄潜叶蛾Tuta absoluta在我国西南、中部和华南地区的地理分布及扩散前沿，摸清其在我国西南地区的分布以及向周边省份扩散蔓延的情况。此次调查范围覆盖云南省、贵州省、四川省、重庆市、西藏自治区、湖北省、湖南省、广西壮族自治区和广东省等省（直辖市、自治区）的100个县192个乡镇。结果表明，在云南省10个县12个乡镇、贵州省13个县25个乡镇、重庆市11个县19个乡镇和广西壮族自治区3个县4个乡镇等地区均有番茄潜叶蛾的发生危害。在四川省的30个县47个乡镇中，有22个县33个乡镇发现番茄潜叶蛾危害；湖北省的7个县16个乡镇中，有5个县11个乡镇发现番茄潜叶蛾危害；湖南省的20个县53个乡镇中，有10个县24个乡镇发现番茄潜叶蛾危害。在西藏自治区的2县4乡镇和广东省4县12个乡镇的调查，都分别只有一个乡镇发现番茄潜叶蛾危害，分别是西藏自治区昌都市芒康县的纳西民族乡和广东省清远市连州市三水瑶族乡。本调查明确了番茄潜叶蛾在西南地区的分布范围以及向四周省份扩散的前沿，为番茄潜叶蛾的监测预警与科学防控提供了数据参考。 |

| he aim of this study was to investigate the geographical distribution and the spread front of Tuta absoluta in the southwest, central and southern parts of China through a field survey, and to find out the distribution of T. absoluta in southwest China and its spread to neighboring provinces. The survey covered 192 townships in 100 counties in the provinces of Yunnan, Guizhou, Sichuan, Chongqing, Xizang, Hubei, Hunan, Guangxi Zhuang Autonomous Region and Guangdong Provinces (municipalities directly under the central government and autonomous regions). The results showed that T. absoluta occurred in 12 townships in 10 counties of Yunnan Province, 25 townships in 13 counties of Guizhou Province, 19 townships in 11 counties of Chongqing Municipality and 4 townships in 3 counties of Guangxi Zhuang Autonomous Region. In Sichuan Province, 30 counties and 47 townships, 22 counties and 33 townships found T. absoluta distribution; in Hubei Province, 7 counties and 16 townships, 5 counties and 11 townships found T. absoluta distribution; in Hunan Province, 20 counties and 53 townships, 10 counties and 24 townships found T. absoluta distribution. In 2 counties and 4 townships in Tibet Autonomous Region and 4 counties and 12 townships in Guangdong Province, only one township was found to be affected by the T. absoluta, which was the Naxi ethnic township in Mangkang County, Chamdo City, Xizang Autonomous Region, and the Sanshui Yao Township in Lianzhou City, Qingyuan City, Guangdong Province, respectively. This survey clarified the distribution area of T. absoluta in the southwest region and the frontiers of its spread to the surrounding provinces, and provided data reference for the monitoring and early warning of T. absoluta as well as the scientific prevention and control of T. absoluta. |
