| 摘 要： | 为阐明金沙江流域蝗区西藏飞蝗(Locusta migratoria tibetensis Chen)发生规律,2007年夏季依据不同植物群落中西藏飞蝗年生活史和种群动态数据分析其发生规律。结果表明:西藏飞蝗在金沙江流域一年发生一代,4月中下旬开始孵化,7月上中旬开始羽化为成虫,8月中旬起进入产卵期。在样地1、样地2和样地3内西藏飞蝗以群居型个体为主,前期虫口密度高,到6月下旬至7月上旬逐渐降低;在样地4内虫口密度低,以散居型个体为主。生境对西藏飞蝗生长发育和消长动态有一定的影响。

| Abstract: | In order to clarify the occurrence of Locusta migratoria tibetensis Chen in Jin Sha Jiang River Valley,we analyzed the life history and population dynamics of L.m.tibetensis Chen based on field data in 2007.Result showed that L.m.tibetensis Chen has one generation per year.Its eggs began hatching in mid-late of April with emergence as adults in mid July starting oviposition in mid August.Swarm of gregarious individuals in plot 1,plot 2 and plot 3,had large population density,then gradually decreased from end of June to first week of July.The population has small density in Plot 4.Growth and dynamics of L.m.tibetensis Chen have different characteristics in different habitat. |
