摘　　要：明确吸虫塔对作物蚜虫防控的指导意义,阐明河南省洛阳地区有翅蚜和中华通草蛉(成虫)的种群动态,为蚜虫防控提供预警信息。2016-2018年通过吸虫塔监测对洛阳地区有翅蚜及中华通草蛉动态开展调查。洛阳地区吸虫塔全年采集有翅蚜量为1.88万~2.43万头,具有2~4个高峰,主要高峰期持续时间约50 d,从4月中旬开始,到6月上旬结束。周有翅蚜量达400头预示着有翅蚜高峰期的到来,高峰期有翅蚜量可占年有翅蚜量的80%以上。吸虫塔全年采集中华通草蛉量约为1.38~1.64千头,具有3-5个高峰,主要高峰期持续约3周,从5月中旬开始,到6月上旬结束。中华通草蛉量过40头预示着中华通草蛉高峰期的到来,高峰期中华通草蛉量可占年中华通草蛉量的55%以上。结果显示,不同年份间有翅蚜和中华通草蛉的高峰期发生时间和发生量均存在着差异,其中,2017、2018年两者高峰期有交集,中华通草蛉高峰期滞后有翅蚜高峰期约3-4周左右。吸虫塔可以很好地反应有翅蚜和中华通草蛉的种群动态,可以进一步开展蚜虫和天敌发生高峰期及高峰点的预测,可为农作物蚜虫的防治提供预警信息。To clarify the effectiveness of suction traps in prevention and control of aphids,and to make clear the population dynamics of alate aphids and Chrysoperla sinica (mature)in Luoyang,Henan Province,so as to provide early warning for aphids control.From 2016 to 2018,a dynamic survey of alate aphids and Chrysoperla sinica was carried out in Luoyang area through suction trap monitoring.Alate aphids collected from the suction traps annually in Luoyang area were 18,800~24,300,there were 2~4 peaks from mid-April to early June,and the main peak lasted for about 50 days.When the weekly number of alate aphids was up to 400,the alate aphids would reach peak,which accounted for more than 80 of the annual number of alate aphids.The annual collection of Chrysoperla sinica from suction traps was about 13,800~16,400,with 3~5 peaks.The main peak period lasted for about 3 weeks from mid-May to early June.A weekly number of 40 Chrysoperla sinica indicated the coming of the peak periods,accounting for more than 55 of the annual amount.The results showed that there were differences in the occurrence time of peak and amount of alate aphids and Chrysoperla sinica in different years.Among them,the peak periods of the two overlapped ores in 2017 and 2018,and the peak period of Chrysoperla sinica lagged behind that of alate aphids for about 3-4 weeks.Suction traps can well reflect the population dynamics of alate aphids and Chrysoperla sinica, and can further predict the peak periods and peak points of aphids and natural enemies.This study can also provide early warning for the prevention and control of crop aphids.
