摘要
为了明确福建闽南地区草地贪夜蛾的种群发生规律以及不同药剂对草地贪夜蛾的防治效果,2021年在福建省龙海地区开展了草地贪夜蛾周年发生动态监测以及药剂防治试验。结果表明,福建闽南地区草地贪夜蛾危害期主要集中在4—11月,一年内共出现2个明显高峰,全年最高诱蛾量在10月上旬,草地贪夜蛾可周年繁殖。苗期、喇叭口期和灌浆期3个不同生育期药剂防控效果比较,化学农药防治区与化学农药+生物农药防治区对草地贪夜蛾的防效均在80%以上,化学农药+生物农药防治区比化学农药防治区产量提高5%,化学农药+生物农药全程防治方案可以在草地贪夜蛾防控上进行推广应用。
In order to clarify the populatiaon occurrence situation and the control effect of pesticides of Spodoptera frugiperda in the south of Fujian Province,the population dynamics of Spodoptera frugiperda in the whole year and the control effect of pesticides of Spodoptera frugiperda were investigated in Longhai District of Fujian Province.The results showed that the corn crop were damaged by Spodoptera frugiperda from A⁃pril to November in south of Fujian Province,and there were two obvious peaks on the adults of Spodoptera frugiperda in the whole year.The highest lure in the whole year was in the first ten days of October,and Spodoptera frugiperda could breed annualy.Comparison the control effect of pesticides of seedling stage,bell stage and filling stage of three different corn stages of Spodoptera frugiperda,the control effect of pesticides of Spodoptera frugiperda were reaching to more than 80%in chemical pesticide control area and chemical pesticide+biological pesticide area.The yield in chemical pesticide+biological pesticide area was more than 5%than in chemical pesticide control area.The technical scheme pes⁃ticides of chemical pesticides+biological pesticides can be used in the controlling of Spodoptera frugiperda.
