摘要: 【目的】研究监测广西东北部稻区白背飞虱早期迁入的峰期,分析其虫源,为白背飞虱的早期预警和有效防治提供依据。【方法】2007—2010年在广西兴安县设置一盏佳多自动虫情测报灯,分析灯诱数据确定迁入高峰期,并运用Hysplit_4软件对其迁入高峰期进行轨迹分析确定虫源地。【结果】广西兴安县白背飞虱一般在5月中旬至6月下旬大量迁入,2007年和2010年白背飞虱早期迁入量远远大于2008和2009年,4年来的最大迁入峰期随着时间推移。轨迹分析显示,虫源地主要位于越南北部、海南、广西南部和广东西南部稻区。【结论】西南低空急流为白背飞虱的大规模北迁提供了运载气流,降雨使得白背飞虱在本地大量降落。

Abstract: 【Objective】The objective of this study is to research on the immigratory peak periods and the source areas of the white-backed planthopper (WBP), Sogatella furcifera (Homoptera: Delphacidae), in the northeast Guangxi of China and to provide a basis for early warning and effective control. 【Method】 The Jiaduo light trap was used to monitor the immigratory peak periods of the WBP in Xing’an country, Guangxi from 2007 to 2010. And the Hysplit_4, a software system was used to analyze their migratory trajectory for ascertaining source areas of the WBP. 【Result】 The immigratory peak periods of the WBP in Xing’an country lasted mainly from the mid-May to the end of June. Immigratory abundance of the WBP population in 2007 and 2010 was higher than that in 2008 and 2009. The highest immigratory peak period went back with time from 2007 to 2010. The trajectory analysis showed that the source areas of the WBP were mainly in the north of the Vietnam, and the part of Hainai Island, the south of Guangxi, the southwest of Guangdong. 【Conclusion】 The low level airflow carried large-scale immigration of the WBP from the source areas to the northeast of Guangxi, while heavy rainfall caused mass descent of the migratory population into the areas.
