摘　　要：对虫果塑料袋闷杀处理、成虫羽化期预测预报和成虫诱杀等柑橘大实蝇防控关键技术进行了研究,结果表明：虫果塑料袋闷杀处理4 d后,幼虫死亡率100%,7 d后大部分虫体变棕褐色,药剂熏蒸效果56%磷化铝〉5%丁硫克百威.毒死碑〉90%敌百虫晶体;各级蛹至羽化高峰的期距为：一级约20~24 d,二级7~10 d,三级5~7 d,四级2~3 d;成虫诱杀采用新配方药剂＂果丰＂进行橘园地面草喷施,比目前生产上应用的＂果瑞特＂点喷防治效果提高23.02个百分点,可以广泛应用于柑橘大实蝇的防治。The key control technologies for Tetradacus citri Chen, such as bagging treatment on sick fruit, adult emergence forecast and adult trapping and killing, were investigated respectively. The results indicated that four days after bagging treatment on sick fruit, the mortality of larvae was evidenced 100%; seven days after bagging treatment on sick fruit, the majority of larvae turned brown. The effects of bagging treatments with different pesticides were ordered as 56% aluminium phosphide 〉5% carbosulfan ~ chlorpyrifos 〉90% dipterex. The intervals from different levels of pupae to the peak period of adult emergence were as follows： about 20-24 days from the first-level, about 7-10 days from the second-level, about 5-7 days from the third-level, and about 2-3 days from the forth-level. The new pesticide ＂ Guofeng＂ were used in adult trapping and killing, which increased the control efficacy by 23.02% in comparison with the control efficacy of spraying commonly used pesticide ＂great＂. Combined application of the above three key control technologies could control Tetradacus cirri Chen effectively.
