摘　　要：为了提高化学药剂对草地贪夜蛾的生物活性,分别采用了浸虫法、浸饲料法和浸虫、饲料法比较了不同橙皮油助剂添加量下草地贪夜蛾对阿维菌素的敏感性,同时借助表面张力仪测定了不同橙皮油助剂添加量下药液的表面张力。结果表明,3种方法获得阿维菌素对草地贪夜蛾的LC_(50)值以浸虫法最高,浸饲料法其次,浸虫、饲料法最低。随着橙皮油助剂含量的增加,阿维菌素对草地贪夜蛾的LC_(50)值先减小后增加,这一变化趋势和橙皮油助剂溶液的表面张力相一致。当橙皮油助剂添加量为0.10%时,阿维菌素对草地贪夜蛾活性最好。本研究结果可为喷雾助剂的科学使用和草地贪夜蛾的化学防治提供依据。In order to improve the activity of pesticides against fall armyworm(Spodoptera frugiperda),susceptibilitiy of fall armyworm to abamectin with orange oil adjuvant was compared by means of insect immersion method,feed immersion method,insect and feed immersion method.At the same time,the surface tension of the liquid with different amount of orange oil adjuvant was measured with the surface tensiometer.The results showed that the LC_(50) value of abamectin to fall armyworm by the insect immersion method was the highest,followed by the feed immersion method,and the insect and feed immersion method being the lowest.With the increase of the content of orange oil adjuvant,the LC_(50) value of abamectin to fall armyworm was decreased initially,and increased afterwards,which was related to the surface tension of orange oil adjuvant solution to some extent.The activity of abamectin to fall armyworm was the best when the amount of orange oil adjuvant was 0.10%.The results of this study could provide a basis for the scientific use of spray adjuvant and the chemical control of fall armyworm.
