涂白剂组合物对油茶蛀干天牛的防控效果

Control Effect of Whitening Agent Composition on Camellia Longicorn Borer

为解决油茶蛀干天牛防治困难的难题,筛选了一种油茶蛀干天牛的物理阻隔防治药剂组合物,对蛀干天牛成虫的趋避率可达100%,对幼虫的毒杀效果在70%以上。在传统涂白剂基础上,白乳胶、桐油、甲维盐·高效氯氟氰菊酯、透翠各成分的加入可产生增效作用,白乳胶可延长涂白剂保护时间,桐油可有效趋避成虫产卵,透翠作为渗透剂载体有助于携带甲维盐·高效氯氟氰菊酯进入木质部杀死天牛等蛀干害虫幼虫。

In order to solve the difficult problem of control Camellia longicorn borer,a kind of composition was screened,the avoidance rate to the adults of longicorn beetles was 100%,the toxic effect on larvae was more than 70%.On the basis of traditional whitening agent,the addition of white latex,tung oil,methotrexate,beta cypermethrin and Turquoise can produce synergistic effect respectively,white latex can prolong the protection time of whitening agent,tung oil can effectively avoid adult spawning,turquoise as a penetrant carrier helped to carry tretinoin and beta cypermethrin into xylem and killed borer larvae.
