摘要: ABSTRACT The toxicity of 10 plant essential oils to adults acaricide-susceptible, chlorfenapyrresistant (CRT-53), fenpropathrin-resistant (FRT-53), pyridaben-resistant (PRT-53), and abamectinresistant (ART-53) strains Tetranychus urticae Koch (Acari: Tetranychidae) female Neoseiulus californicus McGregor Phytoseiidae) was examined using spray or vapor-phase mortality bioassays. In bioassay with the susceptible adults, lemon eucalyptus (19.3 µg/cm3) most toxic oil, followed by peppermint, citronella Java, thyme red, caraway seed, clove leaf, pennyroyal (LC50, 20.6–23.7 µg/cm3). these almost identical against from either resistant strains, even though CRT-53, FRT-53, PRT-53, ART-53 exhibited high levels resistance chlorfenapyr (resistance ratio [RR], >9,140), fenpropathrin (RR, 94), pyridaben >390), abamectin 85), respectively, Against N. californicus, 21...
