摘  要：
采用田间系统调查和灯光诱捕的方法研究了2011年广西兴安地区白背飞虱田间种群发生动态,并运用轨迹分析软件HYSPLIT4.8和气象图形处理软件GrADS对2011年广西兴安地区白背飞虱迁飞高峰期进行轨迹分析和气象背景分析。结果表明:(1)2011年,白背飞虱始见期为5月6日,共有8个迁飞高峰,迁入峰为5月7-10日、6月4-18日、6月27日-7月11日、8月9-11日,8月27日-9月7日,迁出峰为7月17-18日,8月3-5日,10月8日。(2)白背飞虱在双季早稻、单季中稻和双季晚稻混合发生,单季中稻的发生量明显高于双季早稻和双季晚稻。(3)2011年5月上旬白背飞虱迁入虫源主要来自广西西南部稻区,6月上旬大规模迁入虫源来自广西西南部和越南北部稻区。西南气流为白背飞虱的迁入提供了运载气流,降水是迫使白背飞虱降落的主要原因。8月初从本地迁出的白背飞虱随西南气流北上到达湖南西部和北部稻区,10月份迁出的白背飞虱随东北气流南下到达广西的柳州市。

摘  要：
The occurrence dynamics of the white-backed planthopper(WBPH),Sogatella furcifera(Horváth),was studied by using light traps and systematic field surveys in Xing'an of Guangxi Municipality in 2011.The spatiotemporal distribution of the source areas of WBPH migration peaks was analyzed using HYSPLIT4.8(Hybrid Single-Particle Lagrangian Integrated Trajectory),a software package that simulates migration trajectories,and GrADS(Grid Analysis and Display System),a program for analyzing and displaying the synoptic meteorology background during the migration periods.The results showed that:(1) the initial immigration period of WBPH was the 6th of May in Xing'an of Guangxi Municipality in 2011.There were 8 migration peaks.The immigration peaks were the 5-7th of May,the 4-18th of June,the 27th of June-11th of July,the 9-11th of August,the 27th of August-7th of September,and the emigration peaks were 17-18th of July,3-5th of August and 8th of October;(2) WBPH occurred on each of the three annual rice crops(early double-crop,middle-season single-crop,and late double-crop),with some overlapping planthopper generations on more than one crop.The population density of WBPH in the middle-season single-crop rice field was significantly higher than in other two rice fields;(3) the main source areas of the early immigration of WBPH in early May were located in southwestern Guangxi Municipality.A massive immigration in early June probably came from southwestern Guangxi Municipality and northern Vietnam.Analysis of weather conditions during the migration peaks showed that southwest wind carried massive numbers of WBPH into Xing'an,while heavy rainfall caused mass descent.Local WBPH carried by northeast air currents may arrive at Liuzhou of Guangxi Municipality in early October.
