摘　　要：为明确亚致死浓度的氯虫苯甲酰胺连续处理对第4代桃小食心虫生物学特性的影响,本研究用LC_(10)、LC_(30)和LC_(50)的氯虫苯甲酰胺处理的苹果分别继代饲养桃小食心虫(简称LC_(10)、LC_(30)和LC_(50)种群)。以第4代初孵幼虫为起点记录其各阶段发育历期、存活率和繁殖力等数据,研究氯虫苯甲酰胺对桃小食心虫的亚致死效应。结果表明,LC_(30)和LC_(50)种群桃小食心虫的卵期与对照(CK)种群相比明显延长;LC_(50)种群桃小食心虫的蛀果率、脱果率、幼虫存活率、世代存活率以及单雌平均产卵量均显著低于CK种群;CK、LC_(10)、LC_(30)和LC_(50)种群单雌平均产卵量分别为(183.67±10.39)、(177.66±14.81)、(147.83±14.54)粒和(126.33±11.29)粒。桃小食心虫LC_(30)和LC_(50)种群与CK种群相比,内禀增长率、净生殖率和周限增长率显著降低,平均世代周期和种群加倍时间延长,相对适合度降低。This study aimed to clarify the sublethal effect of continuous treatment with chlorantraniliprole on the biological characteristics of the fourth generation peach fruit moth Carposina sasakii.Apples treated with LC_(10),LC_(30)and LC_(50)of chlorantraniliprole were continuously provided to C.sasakii(referred to as LC_(10),LC_(30)and LC_(50)populations).The developmental period,survival rate and fecundity of the fourth generation larvae were recorded to determine the sublethal effect of chlorantraniliprole on C.sasakii.The results showed that the egg duration of LC_(30)and LC_(50)populations was significantly longer than that of CK population.The boring rate,exiting rate,larval survival rate,generation survival rate and average eggs laid per female of LC_(50)populations were significantly lower than those of the CK population,and the average eggs laid per female of CK,LC_(10),LC_(30)and LC_(50)populations were(183.67±10.39),(177.66±14.81),(147.83±14.54)eggs and(126.33±11.29)eggs,respectively.Compared with CK population,the intrinsic growth rate,net reproduction rate and finite rate of increase of LC_(30)and LC_(50)populations were significantly reduced,and the average generation period and population doubling time were prolonged,and the relative fitness was reduced.
