为了明确南靖县草地贪夜蛾种群发生情况和规律,2019年10—12月南靖县进行了草地贪夜蛾发生情况监测,其中对靖城镇、金山镇、和溪镇、船场镇、梅林镇的草地贪夜蛾发生情况进行了调查。结果表明:草地贪夜蛾出现2个发生高峰,最高诱蛾量出现在11月11日,以玉米上草地贪夜蛾成虫发生数量最多,茄子和辣椒上草地贪夜蛾成虫发生数量次之;草地贪夜蛾幼虫只危害玉米,在10月21日左右出现高峰,其他作物上没有发现草地贪夜蛾幼虫危害,其中玉米苗期、小喇叭口期和大喇叭口期危害较重,抽雄后危害较轻。
In order to clarify the population occurrence situation and rule of Spodoptera frugiperda in Nanjing County,the occurrence situation of Spodoptera frugiperda was monitored from October 2019 to December 2019 in Nanjing County,including the occurrence of Spodoptera frugiperda in Jingcheng Town,Jinshan Town,Hexi Town,Chuanchang Town and Meilin Town.The results showed that there were two occurrence peaks on the adults of Spodoptera frugiperda,and the highest induced trapping number appeared on November 11.The number of Spodoptera frugiperda adults in corn planting areas was the highest,followed by eggplant planting areas and pepper plant planting areas.Only corn was harmed by larvae of Spodoptera frugiperda,the peak appeared around October 21,the other corps were not harmed by larvae of Spodoptera frugiperda.The harm to corn was serious in seedling stage,small bell stage and big bell stage,and was lighter after anthesis stage.
