摘要：

为阐明湘桂走廊白背飞虱早期虫源及大气背景在其北迁过程中的影响,利用HYSPLIT软件模拟白背飞虱灾变性迁入高峰期、始见期后向轨迹,分别从个性及共性角度,分析湘桂走廊白背飞虱主要虫源地及其灾变大气背景。结果表明：（1）1991—2014年湘桂走廊白背飞虱的迁入始见期、首次迁入高峰期分别为0.9 d/10 a、1.6 d/10 a;（2）西南路径是湘桂走廊白背飞虱初始虫源迁入的主要路径,永福站、兴安站和全州站虫源西南路径占比分别为54%、50%、72%;（3）中南半岛白背飞虱借助微弱上升气流完成起飞,850 hPa高度上的强劲的西南气流、丰富的水汽条件有利于其北迁,降水是白背飞虱降落的重要大气动力机制。研究结果为白背飞虱的异地监测及科学防治提供科学依据。

Abstract:

To clarify the influence of the early origin and atmospheric background of whitebacked planthopper (Nilaparvata lugens St?l) in Xiang-Gui corridor in the process of its northward immigration, the software HYSPLIT was applied to simulate the catastrophic immigration peak and backward trajectory of WBPH at the beginning occurrence stage, to analyze the main insect source and its catastrophic atmospheric background in terms of individuality and commonness, respectively. The results indicated that: (1) from 1991 to 2014, the beginning occurrence stage of immigration and the immigration peak for the first time of WBPH in Xiang-Gui corridor was 0.9 d/10 a and 1.6 d/10 a, respectively; (2) the southwestern path was the main path for the initial insect source of WBPH in Xiang-Gui corridor, and the southwest path of insect source accounted for 54%, 50%, 72% in Yongfu, Xing’an and Quanzhou station, respectively; (3) WBPH in the Indo-China Peninsula took off with a weak updraft, and the strong southwesterly flow at 850 hPa altitude with abundant water vapor conditions were conducive to its northward immigration; and precipitation was an important atmospheric dynamic mechanism for the landing of WBPH. The results provide a scientific basis for the off-site monitoring and scientific prevention and control of WBPH.

Key words: Xiang-Gui corridor, whitebacked planthopper (WBPH), simulate backward trajectory, space clustering, atmospheric background
