摘　　要：蚜茧蜂是烟蚜的重要天敌类群,广西烟区烟蚜的蚜茧蜂种类及优势种的发生规律尚不明确。本研究通过2021—2023年连续三年对广西烟区烟蚜蚜茧蜂进行田间普查和系统调查,结果表明:广西烟区烟蚜蚜茧蜂主要有烟蚜茧蜂和菜蚜茧蜂,其中,烟蚜茧蜂占94.47%,菜蚜茧蜂占0.72%,非蚜茧蜂占4.81%,说明广西烟区优势蚜茧蜂为烟蚜茧蜂。烟蚜茧蜂发生规律主要呈单峰型,3月下旬至4月上旬是僵蚜和烟蚜茧蜂的始发期,4月底至5月下旬是高峰期,6月上旬为发生末期,6月下旬直至烟叶采烤结束,烟田基本无烟蚜茧蜂发生,各烟区的僵蚜和蚜茧蜂发生情况也符合这一规律。该研究结果可为在广西烟区的合理利用蚜茧蜂防治烟蚜提供参考。Aphidius parasitoids are vital natural enemies of Myzus persicae and play a crucial role in its biological control.However,the species composition and dominant occurrence patterns of Aphidius parasitoids in the tobacco-growing regions of Guangxi remain unclear.This study conducted systematic field surveys from 2021 to 2023 across Guangxi's tobacco-growing areas.Results revealed that the primary aphid parasitoids included Aphidius gifuensis and Diaeretiella rapae.Among them,A.gifuensis accounted for 94.47% of the total parasitic wasps targeting M.persicae,while D.rapae represented 0.72%,and other non-Aphidius parasitoids constituted 4.81%.The occurrence pattern of A.gifuensis was characterized by a single peak:late March to early April marked the initial emergence of mummified aphids and A.gifuensis adults,with the peak occurring from late April to late May.The population declined significantly by early June,and no A.gifuensis was observed in tobacco fields after late June,coinciding with the completion of tobacco leaf harvesting.This occurrence pattern was consistent across all surveyed tobacco-growing regions.These findings provide valuable insights for the effective utilization of A.gifuensis in managing M.persicae populations in Guangxi's tobacco fields.
