摘　　要：为筛选防治赤松梢斑螟Dioryctria sylvestrella的新型绿色高效低成本药剂,探索无人机施药防治赤松梢斑螟的剂量,提高防治效果,分别用3.6%烟碱·苦参碱微囊悬浮剂(CS)、10%吡丙醚乳油(EC)、20%氯虫苯甲酰胺悬浮剂(SC)的3种剂量对赤松梢斑螟进行防治试验。结果表明:3种杀虫剂不同处理组的虫口减退率、被害率减退率和防治效果的差异较大。剂量为450 mL/hm;的20%氯虫苯甲酰胺SC防效最高,达到92.54%;其次是剂量为1500 mL/hm;的3.6%烟碱·苦参碱CS,达到89.71%;3500 mL/hm;的3.6%烟碱·苦参碱CS防效最低,为78.95%。In order to screen new green,high-efficiency,low-cost control agents against Dioryctria sylvestrella,explore the dosage used by drones to control D.sylvestrella to improve the control effect,three doses of nicotine·matrine 3.6%aqueous capsule suspension,pyriproxyfen 10%emulsifiable concentrate,and chlorantraniliprole suspension 20%aqueous suspension concentrate were selected.The results showed that different pesticides had different control effects,and the effects of different treatment groups on the population decline rate,decrease rate of damage rate and control effect on pine cones were different.Chlorantraniliprole suspension 20%aqueous suspension concentrate with a dose of 450 mL/hm;had the best control effect,reaching 92.54%,followed by nicotine·matrine 3.6%aqueous capsule suspension with a dose of 1500 mL/hm;,reaching 89.71%.The lowest control effect of nicotine·matrine 3.6%aqueous capsule suspension with a dose of 3500 mL/hm;was 78.95%.
