摘要
为研究斜纹夜蛾、甜菜夜蛾、小菜蛾的田间种群消长规律,于2016—2017年连续2年在江西吉州区进行了性诱剂监测试验,通过性诱剂诱集的害虫数据分析表明:斜纹夜蛾3—11月份为主要为害时期,5月份开始诱蛾量急剧增多,发生高峰为10月份;甜菜夜蛾3—11月份为主要为害时期,5月份诱蛾量激增,发生高峰为8—9月份;小菜蛾3—6月份、8—11月份为主要为害时期,发生高峰为5月份、9—10月份。
To research the insect population dynamic regulation of Spodoptera litura(Fabricius),Spodoptera exigua Hübner and Plutella xylostella(Linnaeus),application of the sex pheromone trapping technology was used to systemically monitor the insect in Jizhou District from 2016 to 2017.The research showed that Spodoptera litura(Fabricius)occurred mainly from March to November,with the population increasing sharply from May and reaching the peak until October;Spodoptera exigua Hübner occurred mainly from March to November,with the population increasing sharply from May and reaching the peak until August to September;Plutella xylostella(Linnaeus)occurred mainly from March to June and from August to November,with the population reaching two peaks in May,and September to October,respectively.
