摘要
本文测定了5种植物油及其混剂对嗜卷书虱成虫和卵的熏蒸活性。熏蒸24 h后,5种植物油对嗜卷书虱成虫的熏蒸活性由强到弱依次为大蒜油、桉树油、芫荽油、山苍子油和丁香油,其LC50分别为0.89、8.31、9.93、19.05和36.80μL/L空气。嗜卷书虱不同虫态(龄)对植物油熏蒸的敏感性由低到高依次为2日龄卵、4日龄卵、6日龄卵和成虫。桉树油和芫荽油,桉树油和山苍子油的二元混配对嗜卷书虱成虫表现出明显的熏蒸增效作用,其协同毒力指数分别为126.76和135.24。桉树油和芫荽油混合体积比为56:44时,其毒性比率(1.77)和共毒系数最高(160.15)。桉树油和山苍子油混合体积比为50:50时,其毒性比率(1.74)和共毒系数最高(227.35)。
Fumigant activities of five plant oils and their binary mixtures were tested against adults and eggs of Liposcelis bostrychophila Badonnel. After 24 h of exposure, garlic oil exhibited the highest fumigant toxicity against adults of L. bostrychophi[a, followed by eucalyptus, coriander, attarasa and clove oils, with LCs0 values of 0.89, 8.31, 9.93, 19.05 and 36.80 μL/L air, respectively. The highest susceptibility of L. bostrychophila to plant oils was found in adults, followed by 6-, 4- and 2-day eggs. Binary mixtures of eucalyptus/coriander oil and eucalyptus/attarasa oil showed significant synergism with the co-toxicity factor of 126.76 and 135.24, respectively. When mixed at the ratio of 56：44 （v：v）, the synergistic combination of eucalyptus/coriander oil possessed the highest toxicity index of 1.77 and the highest co-toxicity coefficient of 160.15. When mixed at the ratio of 50：50 （v：v）, the synergistic combination of eucalyptus/attarasa oil possessed.the highest toxicity index of 1.74 and the highest co-toxicity coefficient of 227.35.
