摘要
近几年西藏飞蝗Locusta migratoriassp.tibetensis又进入了发生高峰期,从2003年以来逐年加重,2006年危害面积达到25万hm2。通过在西藏阿里、日喀则和四川甘孜、阿坝地区的实地调查,认为2006年是有详细记载以来西藏飞蝗危害面积最大的年份,分布范围也有所扩大,从金沙江沿岸东扩到大渡河沿岸;危害严重区域从雅鲁藏布江流域转移到噶尔河和金沙江流域。
The occurrence of Tibetan migratory locust （Locusta migratoria ssp. tibetensis） came into fastigium again in recent years. Damages caused by this locust increased year by year since 2003 and the disastrous area reached 250 000 hm^2 in 2006. From the result of field survey by author in Tibet and west Sichuan,2006 was the most severe time suffered from Tibetan migratory locust in history of particular recordation. Distribution of the pest was also extended. The most serious regions were displaced from Brahmaputra to Gaerjiang river and Jinshajiang river drainage area, which attracted most attention on research and managent of the pest.
