摘　　要：为探究川东北地区柑橘大实蝇(Bactrocera minax)成虫发生规律及其防控技术,2022—2023年监测了田间柑橘大实蝇成虫羽化情况和发生动态,及室内成虫羽化情况,并进行诱杀效果试验,利用逻辑斯蒂模型拟合柑橘大实蝇成虫羽化和柑橘园成虫发生动态。结果表明:柑橘大实蝇成虫羽化时间为每年5月上旬至5月下旬,羽化高峰期在5月中旬;羽化结束后,田间诱集成虫时间为6月上旬至7月底,诱集高峰期为6月上中旬;室内置蛆柑与田间网罩法监测发现,柑橘大实蝇成虫羽化效果无显著差异。此外在5月下旬开始,在橘园与杂树林交界带连续喷施3次食物诱剂,对柑橘大实蝇的防治效果达92.26%,田间虫果率降低至1.06%,诱杀效果较好,可在柑橘生产中推广应用。In order to study the occurrence regularity of Bactrocera minax adult and its control in Northeastern Sichuan Basin,the emergence and occurrence dynamics of Bactrocera minax adult in the field and the emergence of adult insects indoors were monitored from 2022 to 2023,and the trapping and killing effect experiments were conducted.The logistic model was used to fit the emergence of Bactrocera minax adult and the occurrence dynamics of adult in citrus orchards.The results showed that the emergence of Bactrocera minax adult was occurred from early May to late May,with a peak in mid-May.After its emergence,the trapping adult population spanned from early June to the end of July,with peak trapping in early and mid-June.There was no significant difference between the maggot-infested citrus and the mesh caging method in monitoring the adult emergence.In addition,starting from late May,spraying food attractants at consecutively three times efficiently controlled 92.26% of Bactrocera minax,and reduced the field fruit pest rate to 1.06% at the junction of citrus orchards and mixed woodland.All results demonstrated a commendable trapping and killing effect can be widely promoted in citrus production.
