摘　　要：为了掌握柑桔小实蝇在赣南地区脐橙园中消长规律和防治方法,2020—2022年监测了柑桔小实蝇在失管、半失管、正常管理和网棚栽培等不同类型脐橙园中的发生情况,开展了柑桔小实蝇为害调查及不同措施防治效果比较试验。结果表明,柑桔小实蝇在果实膨大期的虫口发生较严重,超过全年发生量的69.9%,土壤湿度长期低于13.3%或处于单一生境(网棚栽培)时不利于其发生;成虫在9月前主要为害裂果,9月中旬后陆续为害健康果;将普通Steiner式塑料诱捕器颈部(伞盖和瓶体相连部分)柠檬黄色重新漆成桔红色,可提高诱集成虫的效果;8月中旬至11月每120 m^(2)面积挂一个红颈诱捕器,柑桔小实蝇为害率为1.1%,优于阿维菌素、溴氰虫酰胺饵剂的效果。In order to master the dynamic changes of Bactrocera dorsalis(Hendel)and its integrated control in Gannan navel orange orchards,from 2020 to 2022,the occurrence of B.dorsalis in different types of navel orange gardens under normal management,out of control,partial out of control,and net shed were monitored,and the damage of B.dorsalis was investigated and the control effects of different measures were compared.The results showed that the outbreak of B.dorsalis was more serious in the fruit expansion stage,which accounted for more than 69.9%of the annual occurrence.When the soil moisture was below 13.3%for a long time or in monotogenous habitat(net-shed cultivation),it was unfavorable for occurrence of B.dorsalis.The adults B.dorsalis mainly damage the cracked navel orange fruits before September and gradually damage the healthy fruits after mid-September.Painting the Steiner-type plastic trap(the connecting part of the umbrella cap and bottle body)from lemon yellow to orange red could improve the trapping effect on adults.In mid-August,hanging a red-necked trap every 120 m^(2) of navel orange orchard,the annual damage rate of B.dorsalis was 1.1%,which was superior to that of Avermectin and Ambroxol.
