摘要
通过组建自然种群生命表来研究黄缘阿扁叶蜂的种群动态。研究结果表明,黄缘阿扁叶蜂的存活率达14.94%,种群趋势指数为1.152 2。在各虫态中,危害期幼虫期死亡率最高,达到45.97%,其中主要影响因素是气候因素和被捕食。其中捕食性天敌影响很大,黄缘阿扁叶蜂的防治关键时期也在危害期幼虫期。最后,根据这一结果,编制了黄缘阿扁叶蜂防治历。
Population dynamic of Acantholyda flavomarginata Maa was researched by establishing the natural population life table.The results showed that the survival rate of Acantholyda flavomarginata Maa reached 14.94%,and population trend index was 1.152 2.In all stages,mainly influenced by climate and prey factors,the death rate in harm larval stage was the highest,reached 45.97%.In the main factors,predaceous natural enemy has great influence.The key control period of Acantholyda flavomarginata Maa was in the harm larval stage.The control calendar was compiled according to the research.
