CSⅡ不育剂对光肩星天牛的小面积林间喷雾防治试验

Adopting Chemosterilant CSⅡ in Field Control Against the Longicorn, Anoplophora glabripennis

在不育剂室内筛选试验已获成功的基础上 ,为弄清野外应用的效果 ,采用 CS 不育剂(可湿性粉剂 )对光肩星天牛 Anoplophora glabripennis(Motschulsky)进行了小面积林间喷雾防治试验。结果表明 ,采用此不育剂 2 0倍液在天牛成虫羽化盛期进行林间喷雾可得到理想的不育效果 ,天牛卵及初孵幼虫的校正总不育率达 72 .0 8%。

Based on the success of the filtration indoor experiment on some chemosterilants,it was carried out to control the Longicorn, Anoplyophora glabripennis (Motschulsky),by spraying wettable powder,chemosterilant CSⅡ,during the greatly period of eclosion,in order to know the effect of it in the field.The field experiment obtained clear sterile efficiency to the pest.The compensation of total sterile mortality of egg and just hatching larva was 72.08%.
