苏芸金杆菌防治果树害虫试验

EXPERIMENT OF CONTROLLING FRIUT INSECTS WITH SPOREINE

苏芸金杆菌防治果树害虫较好,不杀伤天敌,不污染环境,无残毒,是理想的无公害农药,通过室内试验,60A、HD-73防治核桃缀叶螟、1013防治苹掌舟蛾、HD-73防治舞毒蛾、1013 HD-73防治中国绿剌蛾,杀虫效果均达93.33～100％。对蚕有药害,HD-1、对4龄蚕杀伤88-90％,HD-73、60A、1013杀伤18-50％。故不能应用于蚕区桑树害虫防治。

For no damage to native predator and without residual toxicity and pollution to enviroment, sporeine was a no public nuisance farm insecticide in controlling fruit insects. Tested in labory, insecticidal effecience was 93.33-100％ with 60A, HD-73 to control Locastra muscosalis walker, 1013 to black-marked prominent (Phalera Havescens) HD-73 to Chinese cochlid (Parpsa sinica Moore) and 1013 HD-73 to gypsy moth (Lymantria dispar). But sporeine can't be applied to control mulberry insects for it is damageful to silkworm.
