摘要

摘要: 开展树干注射印楝素对柑橘全爪螨的控制作用研究。结果表明,每厘米胸径树干注射1~3mg印楝素在药后7d对柑橘全爪螨田间防治效果可达90%以上,持续至60d仍可达75%以上;测定内吸印楝素对各螨态柑橘全爪螨的亚致死剂量,发现其对柑橘全爪螨种群具有延长发育历期、降低繁殖力的长期控制效应。

Abstract: The control effect of azadirachtin with trunk injection at 1-3 mg per cm DBH(diameter at breast height) was above 90% on Panonychus citri(McGregor) 7 days after injection in the field,and remained above 75% in 60 days.The sublethal doses of azadirachtin on different developmental stages of P.citri were determined and their long-term effects on P.citri population were discovered to be the extension of developmental duration and reduced fecundity.
