（南京农业大学植物保护学院昆虫学系 农作物生物灾害综合治理教育部和农业部重点实验室南京210095）摘要通过灯诱和田间系统调查以及长翅型雌虫卵巢解剖，研究了山东济宁灰飞虱Laodelphax striatellus (Fallén)在灯下、麦田和秧田的种群消长动态及虫源性质。运用GrADS和ArcGIS 分析了2009年6月7日迁入峰和2010年6月15日迁出峰的天气学背景，并运用HYSPLIT轨迹分析平台模拟了这2个时期灰飞虱的迁飞路径。结果表明：（1）2009年6月7日、8日，2010年6月3日至7日为济宁灰飞虱的迁入高峰期; 2009年6月2日至4日、9日，2010年6月8日，6月15日至18日为济宁灰飞虱的迁出高峰期。（2）回推轨迹分析显示2009年6月7日迁入济宁的灰飞虱的虫源地主要为江苏省宿迁市沭阳县和泗洪县及丹阳市，而顺推轨迹分析显示2010年6月15日济宁灰飞虱迁出可能降落于辽宁省朝阳市喀喇沁左翼蒙古族自治县、大连市与丹东市交界及朝鲜江原道。（3）降雨是导致灰飞虱迁入或迁出降落的最主要因子,灰飞虱降落于降水区的边缘。

AbstractThe population dynamics and generation structure of the small brown planthopper (SBPH) in wheat and rice seedling fields in Jining, southwest Shandong Province, China, were studied through systematic field survey and the dissection of the ovaries of macropterous females. Grads and ArcGIS were used to analyze weather conditions during the immigration peak detected on the 7th of June 2009 and the emigration peak detected on 15th of June 2010. The migration pathways of SBPH were simulated in the above two periods by HYSPLIT, trajectory analysis software for the simulation of migration trajectories. The main results are as follows: (1) Peak immigration of SBPH in Jining was concentrated on the 7th and 8th June 2009, and the 3rd to 7th of June 2010 whereas the emigration peak was concentrated on the 2nd to 4th and 9th of June 2009 and the 8th and 15th to 18th June 2010. (2) Backward trajectory analysis showed that the source regions of the immigrant populations observed on the 7th of June 2009 were mainly in Shuyang and Sihong County, in Suqian, northern Jiangsu, and Danyang in southern Jiangsu, while forward trajectory analysis showed that SBPH may emigrate from Jining to the Mongolian Autonomous County of Harqin Left Wing, Zhaoyang, western Liaoning, the junction of Dalian and Dandong and Gangwondo in North Korea on the 15th of June, 2010. (3) Heavy precipitation appear to be the main factors affecting SBPH settlement during immigration or emigration; settlement areas were on the edge of the main rainfall zones.
