根据吉林省美国白蛾的发生状况及疫区冬季的实际温度条件,分析了美国白蛾越冬的安全性与扩散的可能性,结果表明:美国白蛾在吉林省未感染区域的冬季气温条件下可以安全越冬,冬季低温不能阻止美国白蛾在吉林境内的进一步扩散;提出了疫区以根除为主、边界区以监控为主、非感染区以保护预防为主的阻止美国白蛾扩散对策。
根據吉林省美國白蛾的髮生狀況及疫區鼕季的實際溫度條件,分析瞭美國白蛾越鼕的安全性與擴散的可能性,結果錶明:美國白蛾在吉林省未感染區域的鼕季氣溫條件下可以安全越鼕,鼕季低溫不能阻止美國白蛾在吉林境內的進一步擴散;提齣瞭疫區以根除為主、邊界區以鑑控為主、非感染區以保護預防為主的阻止美國白蛾擴散對策。

The overwintering security and diffusion possibility of Hyphantria cunea was analyzed according to the occurrence and actual temperature condition of epidemic area in winter of Hyphantria cunea in Jilin province.The result showed that Hyphantria cunea can live through the winter safely in the condition of winter temperature of uninfected areas of Jilin prov-ince.The further diffusion of Hyphantria cunea in Jilin province can be inhibited by winter low temperature.The strategy of taking the eradication, monitoring and prevention as the principal thing in epidemic, boundary area and uninfected areas was raised for preventing Hyphantria cunea diffusion.
