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 research on the key technologies of preventing and controlling citrus fruit fly, such as the stuffing and killing of plastic bag, the prediction and forecasting of adult eclosion stage and the adult trapping and killing, showed that the mortality rate of larvae was 100% Most of the parasites turned brown after 7 days, and the drug fumigation effect was 56%. Aluminum phosphide> 5% butadienstatin. Toxic tablet> 90% of trichlorfon crystals; The first grade was about 20-24 days, the second grade was 7-10 days, the third grade was 5-7 days, and the fourth grade was 2-3 days. The adults were killed and killed by the new prescription drug “Guo Feng” At present, the production application “Gurit ” point spray prevention and control effect increased by 23.02 percentage points, can be widely used in the prevention and control of citrus fruit fly.
