A total of 53 plant essential oils were tested for their insecticidal activities against eggs, nymphs, and adults of Trialeurodes vaporariorum Westwood, using an impregnated filter paper bioassays without allowing direct contact. Responses varied according to oil type and dose, and developmental stage of the insect. Bay, caraway seed, clove leaf, lemon eucalyptus, lime dis 5 F, pennyroyal, peppermint, rosewood, spearmint, and tea tree oils were highly effective against T. vaporariorum adults, nymphs, and eggs at 0.0023, 0.0093, and 0.0047 microl/ml air, respectively. These results indicate that the mode of delivery of these essential oils was largely a result of action in the vapor phase. Significant correlations among adulticidal, nymphicidal, and ovicidal activities of the test oils were observed. The essential oils described herein merit further study as potential fumigants for T. vaporariorum control.
总共测试了53种植物精油对温室白粉虱若虫、成虫和卵的杀虫活性,采用浸渍滤纸生物测定法,不允许直接接触。反应因油的类型、剂量和昆虫的发育阶段而异。月桂、香菜籽、丁香叶、柠檬桉、酸橙dis 5 F、薄荷、薄荷、玫瑰木、留兰香和茶树油在空气中浓度分别为0.0023、0.0093和0.0047微升/毫升时,对温室白粉虱成虫、若虫和卵高效。这些结果表明,这些精油的作用方式主要是气相作用。观察到测试油的杀成虫、杀若虫和杀卵活性之间存在显著相关性。本文所述的精油作为控制温室白粉虱的潜在熏蒸剂值得进一步研究。
