摘　　要：为书虱的抗性治理提供科学指导,本研究采用培养皿药膜法测定了4种储粮保护剂对5种书虱的触杀毒力,并采用广口瓶密闭熏蒸法测定了8种植物精油对嗜卷书虱的熏蒸活性。同时,评估了药剂复配及其与辣根素精油联用对嗜卷书虱的协同毒力。结果表明,书虱对马拉硫磷、甲基嘧啶磷、高效氯氰菊酯和溴氰菊酯均表现出较高敏感性,LD_(50)在0.041~0.977μg/cm^(2)之间,可作为敏感基线使用;辣根素精油对书虱的熏蒸活性最高。马拉硫磷和溴氰菊酯复配体积比为4∶5时,增效作用最佳;而甲基嘧啶磷和高效氯氰菊酯配比在2∶1时,增效作用最佳。此外,辣根素与甲基嘧啶磷或高效氯氰菊酯联用均具有增效作用。To scientifically guide the resistance management of booklice in storage,the contact toxicity of four types of grain protectants to five species of booklice was determined using petri dish film method.Additionally,we assessed the fumigation activity of eight plant essential oils against Liposcelis bostrychophila using the wide-mouth bottle fumigation method.Meanwhile,the synergistic effects of organophosphorus and pyrethroid insecticides,along with their combination with allyl isothiocyanate(AITC)essential oil,against booklice were evaluated.The results indicated that five species of booklice exhibited high sensitivity to malathion,pirimiphos-methyl,deltamethrin and beta-cypermethrin,with LD_(50) values ranging from 0.041μg/cm^(2) to 0.977μg/cm^(2),which could serve as the sensitive baseline.Fumigation test revealed that AITC exhibited excellent fumigant activity against booklice.The mixture of malathion and cypermethrin at a volume ratio of 4∶5 showed the optimal synergistic effect,while the combination of pirimiphos-methyl and beta-cypermethrin at a ratio of 2∶1 exhibited the optimal synergistic effect.In addition,AITC also exhibited a synergistic effect when combined with pirimiphos-methyl or beta-cypermethrin.
