摘要:

玉兰大刺叶蜂Megabeleses crassitarsis Takeuchi是近几年发现的一种新害虫,中国新记录种。严重危害白玉兰Magnolia denudata Desr和紫玉兰Magnolia liliflora Desr,分布于安徽大别山区。1年发生1代,以预蛹在土壤内茧中越夏越冬。幼虫食叶危害,每年5月上、中旬为猖獗危害期。此虫发生与海拔、温度、湿度关系密切。以80 %敌敌畏乳油稀释1500倍喷射3龄前幼虫,可杀死幼虫95%以上。

Abstract:

The swafly, Megabeleses crassitiarsis Takeuchi, is a newly recorded insectpest in China.It occurred in Dabieshan Mountains, east China.Its host plants are yula magnolia, Magnolia denudata Desr.and lily magnolia, Magnolia liliflora Desr..It has one generation per year and overwinters as prepupa in cocoon in the topsoil.The larvae occur from early May to mid-May; the trees were seriously damaged in this period.The incidence of this pest is closely related to elevation, temperature and moisture.The larvae(before third instar) were >95 % controlled by 80% DDVp emulsion at 1500×dilation during mid-May in Huoshan County.
