茶藨子透翅蛾生物学及综合防治研究

茶藨子透翅蛾系鳞翅目、透翅蛾科害虫,成虫体青黑色,腹部有黄色窄带,外形似胡蜂.幼虫钻蛀危害茶藨子属灌木枝条,蛀道可达30～40cm;被害枝条髓心被蛀食一空、伤流严重、营养生长及花芽分化均受到抑制,并易引发病害侵染,越冬后大量造成死亡,至使严重减产.本文对该虫的形态特征、性引诱现象、性外激素有机提取物的性引诱活性等生物学特性及综合防治进行了研究.

Studies on Biology and Synthetically Preventive Treatment of Synanthedon tipliformis

Synanthedon tipliformis is a kind of harmful insect belonging to Aegeriidae of Lepidoptera. The adults seem like yeiiow-jeackets,its body blue-black, and its belly having yellow narrow girdles. The larvas bore shrub outgrow of Ribes. Length of bored holes sometimes is 30-40cm. Since pith of damaged outgrow becomes empty and sap flows outside the branches,the vegetative growth and differentiation of fruit buds are restrained,and the trees are infested disease easily and die in quantities. Fruit yield reduces greatly. The integrated managenent based on sex attraction is also studied in this paper.
