摘　　要：【目的】研究取食农田残膜对大蜡螟种群延续的影响。【方法】以麦麸(MF)和新疆农田残膜(NTCM)不同配比作饲料(即MF,50%NTCM,100%NTCM 3个处理),在恒温30℃、60%±10%RH(相对湿度)条件下饲养大蜡螟2个世代。【结果】(1)大蜡螟幼虫取食麦麸量随残膜添加量的增加而减少(P<0.05),取食残膜量随添加残膜量的增加而增加,各处理第二代取食麦麸量较第一代减少,而取食残膜量增加;对农田残膜和麦麸的总取食量随残膜添加量的增加而减小,MF处理总取食量第二代较第一代减少,50%NTCM和100%NTCM处理总取食量第二代较第一代增加。(2)大蜡螟蛹重、蛹长均随残膜量的增加而减小,3个处理第二代蛹重及蛹长均低于第一代(P>0.05);不同处理对大蜡螟雌雄蛾体重影响不显著,且各处理第二代雌雄蛾体重均低于第一代(P>0.05),而不同处理大蜡螟雌雄蛾体长无明显变化规律。(3)大蜡螟雌蛾产卵量随残膜量增加而减小,100%NTCM处理第二代产卵量大于第一代(P>0.05),MF和50%NTCM处理第二代产卵量小于第一代(P<0.05);大蜡螟卵孵化率随农田残膜添加量增加而减小(P>0.05),第二代孵化率小于第一代(P>0.05)。【结论】以新疆农田残膜和麦麸不同配比为饲料,大蜡螟幼虫取食残膜量随麦麸添加量增加而减小,各处理第二代取食麦麸量较第一代减少,而取食残膜量增加;大蜡螟蛹重、蛹长均随残膜量的增加而减小,3个处理第二代蛹重及蛹长均低于第一代;不同处理对大蜡螟雌雄蛾体重影响不显著,且各处理第二代雌雄蛾体重均低于第一代,而不同处理大蜡螟雌雄蛾体长无明显变化规律;大蜡螟产卵量、卵孵化率均随残膜量增加而减小,第二代孵化率均小于第一代,但100%NTCM处理第二代产卵量大于第一代。【Objective】In order to study the effects on population continuation of Galleria mellonella fed with farmland residual film.【Methods】Two generations of Galleria mellonella were reared at constant temperature of 30℃and 60%±10%RH(relative humidity)with wheat bran and Xinjiang farmland residual film as feed(MF,50%NTCM,100%NTCM).【Results】The results showed that:(1)The feeding amount of wheat bran decreased with the increase of residual film addition(P<0.05).The feeding amount of residual film increased with the increase of residual film addition.The second generation of each treatment consumed less wheat bran than the first generation,while the amount of residual film consumed increased.The total feeding amount of farmland residual film and wheat bran decreased with the increase of residual film addition.The total feeding amount of MF treatment was lower than that of the first generation,and that of 50%NTCM and 100%NTCM treatment was higher than that of the second generation.(2)The pupal weight and pupal length decreased with the increase of residual film addition,and the pupal weight and pupal length of the second generation were lower than those of the first generation(P>0.05).Different treatments had no significant effect on the body weight of male and female moths,and the body weight of the second generation of male and female moths in each treatment was lower than that of the first generation(P>0.05).There were no significant change rules in the body length of male and female moths in different treatments.(3)The egg-production of female moths decreased with the increase of residual film.The egg-production of the second generation of 100%NTCM treatment was greater than that of the first generation(P>0.05).The egg-production of the second generation of MF and 50%NTCM treatment was less than that of the first generation(P<0.05).The hatching rate decreased with the increase of residual film addition(P>0.05),and the hatching rate of the second generation was less than that of the first generation(P>0.05
