摘　　要：2019~2021年定点系统观察了绣线菊蚜的发生规律,结果显示:(1)科左中旗沙棘林绣线菊绣线菊蚜5月上中旬始见,6月上中旬为始盛期,7月上中旬为发生高峰期,8月为发生盛末期,9月下旬为终见期;平均温度15.8℃以上开台活动活跃,平均温度28℃以内时,温度越高,越有利于其发生。均匀适度的降雨结合适宜的温度,适宜绣线菊蚜大量繁殖、生长。(2)烯啶虫胺、噻虫嗪、吡虫啉等3种农药可作为防治绣线菊蚜的专用药剂,交替使用。10%烯啶虫胺可溶性液剂、25%噻虫嗪WDG、10%吡虫啉可湿性粉剂施药推荐浓度分别是4000~5000倍液、5000~10000倍液、3000~4000倍液。高效氯氰菊酯乳油对绣线菊蚜有一定的控制作用,可作为防治绣线菊蚜的兼治药剂,一般不推荐为专用杀蚜剂。After the test observation,the aphid of embroidery thread in the sea buckthorn forest of Kezuozhongqi was seen in the first half of May,the first half of June was the beginning of the blooming period,the first half of July was the peak of the occurrence,August was the end of the blooming period,and the second half of September was the end of the blooming period;the average temperature of 15.8℃above the open table activity is active,the higher the temperature when the average temperature is within 28℃,the more favorable to its occurrence.The average rainfall combined with the appropriate temperature,suitable for aphids to multiply and grow.The results of the drug screening test showed that three pesticides,such as oxytetracycline,thiamethoxam and imidacloprid,can be used alternately as a special agent to control the aphid.10%oxytetracycline soluble liquid,25%thiamethoxam WDG,10%imidacloprid wettable powder application recommended concentration is 4000~5000 times,5000~10000 times,respectively.The recommended concentrations of application are 4000~5000 times,5000~10000 times and 3000~4000 times respectively.Efficient cyhalothrin emulsifiable oil has a certain control effect on hydrangea aphid,and can be used as a part-time agent to control hydrangea aphid,but generally not recommended as a special aphicide.
