| 摘 要： | 2019年12月-2020年3月初调查结果显示,草地贪夜蛾在我国云南、广东、海南、四川、广西、福建、贵州7省(区)的47个市(州)183个县(市、区)发生,玉米是其冬季主要寄主作物,局部地区可见为害小麦和甘蔗;福建、广东、广西、贵州在幼虫冬繁区以外地区诱到成虫。浙江、湖南、江西、重庆等4省(市)的16个市27个县(市、区)在30个点查到活虫(蛹)。验证了我国草地贪夜蛾冬繁区即周年繁殖区位于28°N以南,即1月份平均温度10℃等温线以南区域;越冬区在28°N-31°N之间,即1月份平均温度6℃等温线到10℃等温线之间。

| Abstract: | According to field investigations during the winter from December 2019 to early March 2020,Spodoptera frugiperda was confirmed to occur in 183 counties of 47 cities in Yunnan,Guangdong,Hainan,Sichuan,Guangxi,Fujian and Guizhou,China.S.frugiperda populations surviving over the last winter primarily fed on maize,and partly lived on wheat and sugarcane.S.frugiperda adults were trapped in some regions outside the winter breeding area of Fujian,Guangdong,Guangxi and Guizhou provinces.Some larvae(or pupae)were found alive at 30 sites in 27 counties of 16 cities in Zhejiang,Hunan,Jiangxi and Chongqing.The results showed that the winter breeding area is located in the south of 28°N,which is nearly the south of the 10℃isotherm in January.The overwintering area is between 28°N-31°N,approximately the area between the 6℃isotherm and 10℃isotherm in January. |
