摘要
对楚雄市紫溪山林场华山松种子园华山松球果螟进行防治试验研究。结果表明,人工清除华山松受害球果,利用纱网罩住,保护释放天敌的防治方法,操作简便,防治效果显著,且不污染环境,对人畜安全;在成虫羽化盛期喷洒印楝灭虫剂对降低华山松球果螟的种群密度具一定作用;4种农药对华山松球果螟的杀灭效果均较好,以1∶1000倍液的80%敌敌畏乳油防治效果最佳。
The control test of Dioryctria rubella Hampson was conducted in the seed orchard of Pinus armandi in Zixishan Forest Farm of Chuxiong City.The results showed that the method of manual removal of damaged cones,covering with gauze and releasing natural enemies,was not only simple and effective,but also not polluting the environment and safe for human and livestock;in the peak period of adult emergence,Azadirachtin insecticide had a certain effect on reducing the population density of Dioryctria rubella;the killing effect of four kinds of pesticides was significant,but the control effect of 80%dichlorvos EC with 1∶1000 times solution was the best.
