摘　　要：为深入分析广西不同烟区主要害虫的发生动态,提供防控相应害虫的理论依据,2021—2023年在广西贺州市和靖西市对主要害虫的发生情况进行田间普查和系统调查。田间普查结果表明,贺州烟蚜和斜纹夜蛾各年份间无显著性差异,烟青虫发生量2022年显著高于2023年;靖西烟蚜发生量2022年显著高于其他年份,斜纹夜蛾和烟青虫2021年显著高于其他年份,广西烟区3种害虫的发生量并未呈现逐年增加或减少的趋势。系统调查表明,贺州烟蚜、烟青虫和斜纹夜蛾的集中发生时间分别在5月上旬和5月下旬、5月上旬至6月中旬、5月上旬至6月中旬;靖西在3月下旬至5月上旬、5月上旬和5月下旬、5月上旬至6月上旬,靖西3种害虫的集中发生时间均早于贺州。研究结果揭示了广西不同生态烟区烟蚜、烟青虫和斜纹夜蛾的发生动态,对指导以上3种害虫的测报调查和精准防控具有重要意义。To gain a deeper understanding of the occurrence dynamics of main pests in different tobacco-producing areas in Guangxi and to provide a theoretical basis for the prevention and control of corresponding pests,a filed census and systematic survey of the occurrence of major pests were carried out in Hezhou and Jingxi from 2021 to 2023.The results of the field census showed that there was no significant difference in the occurrence of Myzus persicae and Spodoptera litura between years in Hezhou,and the incidence of Helicoverpa assulta was significantly higher in 2022 than that in 2023.The prevaience of M.percicae in Jingxi was significantly elevated in 2022 in comparison to other years.The occurrence of S.litura and H.assulta in 2021 was significantly higher than that in other years.The occurrence of the three pests in the Guangxi tobacco-producing area did not show a discernible trend of increase or decrease on an annual basis.The systematic survey showed that the concentrated occurrence of M.percicae,H.assulta,and S.litura was observed in Hezhou during the period of early May and late May,early May to mid-June,and early May to mid-June,respectively.The concentrated occurrence of the three pests in Jingxi was earlier than that in Hezhou,occurring from late March to early May,early May and late May,and early May to early June,respectively.The results of this study clarified the occurrence dynamics of M.percicae,H.assulta,and S.litura in different ecological tobacco-producing areas of Guangxi,offering important theoretical significance for guiding future forecasting investigation and precise control for these three pests.
