青枣咖啡黑点蠹蛾生物学特性及其防治

Biological Properties and Control of Zeuzera Coffeae Nietner

近年来,义乌枣树咖啡黑点蠹蛾发生严重。经观察试验,此虫在义乌一年发生1代,以幼虫在被害枝内越冬,此虫的发生与环境因子关系密切。提出了以人工防治为主、化学防治为副的综合治理措施。

A note was given to severe attack of Zeuzera coffeae Nietner in Ziziphus jujubaMill in Yiwu city, Zhejiang Province. Observations and experiments showed one generation inthe year, larva overwinted in attacked branch. The incidence of the insect had close relations-hip with environment. Artificial control as the major method, chemical control as supplement-ary were proposed.
