摘　　要：为了了解吡虫啉，阿维菌素和高效氯氰菊酯不同亚致死剂量对绿色型豌豆蚜实验种群参数的影响，阐明绿色型豌豆蚜发育及繁殖与亚致死剂量的关系，并为豌豆蚜的综合防治提供理论依据。在22～24℃，光照周期L∶D＝16 h∶8 h，相对湿度（RH）70％～80％条件下，采用带虫浸叶法确定吡虫啉，阿维菌素和高效氯氰菊酯对绿色型豌豆蚜的亚致死剂量，通过叶碟饲养，记录其发育历期、产蚜量和寿命。结果表明，吡虫啉，阿维菌素和高效氯氰菊酯LC20、LC10分别处理成蚜后，成蚜平均寿命和平均产蚜量均显著低于对照（P＜0．05），其中阿维菌素LC20处理平均寿命最短为3．34 d，高效氯氰菊酯 LC20处理平均产蚜量最低为14．30头；F1代除3龄历期无显著差异外（P＞0．05），其余各龄期历期变化规律不明显，但成虫期、存活率、平均产蚜量、净增殖率及平均世代周期均表现为LC10大于LC20，在阿维菌素LC10下，F1代成蚜寿命、成蚜平均产蚜量、净增殖率及平均世代周期达到最大值且均大于对照，分别为9．76，77．76，65．32，12．41。表明吡虫啉，阿维菌素和高效氯氰菊酯不同亚致死剂量处理成蚜后，对其寿命和繁殖力均起到抑制作用，但对F1代影响表现为大部分生物学参数随亚致死剂量降低而升高。To understand the effects of sublethal dosage of imidacloprid,abamectin and beta-cypermethrin on the experimental population parameter of green morph of pea aphid [Acyrthosiphonpisum （Hemiptera：aphidi-ae）],and to investigate the relationship between the development,reproduction of A.pisum and sublethal dosage,which can provide a theoretical basis for comprehensive control of A.pisum.Sublethal dosage of imid-acloprid,abamectin and beta-cypermethrin on A.pisum were examined by leaf with insect dipping method and disc leaf dipped method respectively under constant temperature （22-24）℃,relative humidity （70%-80%） and a 16∶8 （L∶D）hours photoperiod.The results showed that mean longevity and fecundity of the adults treated by two concentrations （LC20 and LC10 ）of three kinds of insecticides were significantly lower than those of the control （P〈0.05）.Both the mean longevity and the fecundity of the adults treated by abamectin （LC20 ） and beta-cypermethrin （LC20 ）reached its minimum,which were 3.34 days and 14.30 heads,respectively. However,no significant regulations were found on the durations of different developmental stages of F1 genera-tion nymphs except that the third instar had no significant differences （P〉0.05）,while the adult stage,mean longevity,survival rate,mean fecundity,net reproductive rate （R0 ）and mean generation time （T）of F1 gener-ation treated by concentrations （LC10 ）were larger than concentrations （LC20 ）of three kinds of insecticides. Especially,the adult stage,mean fecundity of adults,net reproductive rate （R0 ）and mean generation time （T） of F1 generation treated by abamectin （LC10 ）reached its manimum value,which were 9.76,77.76,65.32, 12.41 respectively,were larger than those of the control.All these results showed that both of the mean lon-gevity and fecundity of adults were decreased,while most life table parameters of F1 generation improved with decrease of sublethal dosage after the adults were treated by different
