摘要：

2016—2019年采用性信息素诱捕器监测昆明菜区甜菜夜蛾和斜纹夜蛾种群。结果表明,甜菜夜蛾和斜纹夜蛾全年都发生危害,全年发生1~2个高峰期,斜纹夜蛾诱集虫量是甜菜夜蛾虫量的7.09~14.89倍。2016—2017年甜菜夜蛾发生高峰期都在5月下旬—10月中下旬;2018年发生高峰期在5月10日—7月31日和8月31日—9月10日;2019年全年虫量最少,发生高峰期在4月下旬—9月下旬。2016年斜纹夜蛾发生高峰期在5月下旬—10月上旬;2017年发生高峰期在6月30日—8月31日和9月30日—11月30日;2018年发生高峰期在5月10日—7月31日、11月;2019年发生高峰期在4月30日—9月30日、11月。甜菜夜蛾和斜纹夜蛾发生高峰期在夏秋季,本研究可为昆明菜区甜菜夜蛾和斜纹夜蛾绿色防控提供数据参考。

Abstract:

From 2016 to 2019, populations of Spodoptera exigua adults and Spodoptera litura adults were monitored by using sex pheromone traps on vegetable areas in Kunming. The results showed that: S. exigua and S. litura were harmful all year round. There were one or two peak periods in the whole year, and the trapped number of S. litura was 7.09 to 14.89 times of that of S. exigua. From 2016 to 2017, the peak of S exigua was from late May to mid-to-late October. In 2018, the peak occurred from May 10 to July 31 and from August 31 to September 10. In 2019, the pest quantity was the lowest, and the peak occurred from late April to late September. In 2016, the peak of S. litura occurred from late May to early October. In 2017, the peak occurred from June 30 to August 31 and from September 30 to November 30. In 2018, the peak occurred from May 10 to July 31 and November. In 2019, the peak occurred from April 30 to September 30 and November. The peak period of S. exigua and S. litura occurred in summer and autumn. This study could provide data reference for the green prevention and control of S. exigua and S. litura in Kunming vegetable areas.

Key words: Kunming, vegetable, Spodoptera exigua, Spodoptera litura, occurrence regularity
