摘　　要：为烤烟夜蛾科害虫的精准防控提供参考,在施秉县不同海拔烟区利用性诱剂对斜纹夜蛾、小地老虎、棉铃虫和烟青虫的田间发生规律进行监测。结果表明:不同海拔烟区烤烟夜蛾科害虫发生均以斜纹夜蛾为主,小地老虎次之,棉铃虫和烟青虫发生量均较少;斜纹夜蛾发生高峰期主要在4月下旬至5月中旬、9月下旬至12月上旬,6-8月诱蛾数量相对少而稳定;小地老虎的发生期主要在3-6月,诱蛾高峰主要在3月中旬至4月下旬,5-6月诱蛾量均较低;棉铃虫主要发生在4月中旬至5月中旬;烟青虫主要发生在5月上旬至6月中旬;斜纹夜蛾、小地老虎、棉铃虫和烟青虫平均诱蛾量均随着海拔的升高呈下降趋势,不同海拔烟区小地老虎和烟青虫7d平均诱蛾量无显著差异,而斜纹夜蛾和棉铃虫存在显著性差异。In order to provide references for the precise prevention and control of flue-cured tobacco Noctuidae pests,sex attractants were employed in tobacco areas at different altitudes in Shibing County to monitor the occurrence of Spodoptera litura,Agrotis ypsilon,Helicoverpa armgera,and Heliothis assulta.Results:Noctuidae pest S.litura occurred the most in tobacco areas at different altitudes,followed by A.ypsilon,H.armigeraand H.assulta were less found;The peak occurrence period of S.litura was mainly from late April to mid-May,late September to early December,the number of trapped Noctuidae pests was relatively small and stable from June to August;The occurrence period of A.ypsilon was mainly from March to June,and the peak time of Noctuidae pests trapped was mainly from mid-March to late April.The quantity of Noctuidae pests trapped was low from May to June;H.armigera mainly occurred from mid-April to mid-May;H.assulta mainly occurred from early May to mid-June;The quantity of trapped S.litura,A.ypsilon,H.armgera,and H.assulta decreased with altitude.There was no significant difference in the 7 dtrapped number of A.ypsilon and H.assulta,while significant difference was observed between S.lituraand H.armgera.
