Abstract

The insecticidal activities of 13 Lamiaceae plant oils and their components against adult German cockroaches, Blattella germanica L. (Blattodea: Blattellidae), were evaluated using fumigant and contact bioassay. Among the tested oils, basil, pennyroyal, and spearmint showed the strongest insecticidal activities against adult B. germanica. Insecticidal activity of pennyroyal was 100% against male B. germanica at 1.25 mg concentration in fumigant bioassay. Basil and spearmint revealed 100% and 100% insecticidal activity against male B. germanica at 5 mg concentration, but their activities reduced to 80% and 25% at 2.5 mg concentration, respectively. In contact, toxicity bioassay, basil, pennyroyal, and spearmint oils exhibited 100%, 100%, and 98% mortality against female B. germanica at 1 mg/♀, respectively. Among the constituents identified in basil, pennyroyal, and spearmint oils, insecticidal activity of pulegone was the strongest against male and female B. germanica.

摘要

使用熏蒸法和接触法生物测定，评估了13种唇形科植物油及其成分对德国小蠊成虫（蜚蠊目：姬蠊科）的杀虫活性。在所测试的油中，罗勒、薄荷油和留兰香对德国小蠊成虫表现出最强的杀虫活性。在熏蒸法生物测定中，薄荷油在浓度为1.25毫克时对雄性德国小蠊的杀虫活性为100%。罗勒和留兰香在浓度为5毫克时对雄性德国小蠊的杀虫活性分别为100%和100%，但在浓度为2.5毫克时，它们的活性分别降至80%和25%。在接触毒性生物测定中，罗勒油、薄荷油和留兰香油在浓度为1毫克/♀时对雌性德国小蠊的死亡率分别为100%、100%和98%。在罗勒、薄荷油和留兰香油中鉴定出的成分中，长叶薄荷酮对雄性和雌性德国小蠊的杀虫活性最强。
