The fumigant and contact toxicities of 16 Asteraceae plant essential oils and their constituents against adult male and female Blattella germanica were examined. In a fumigant toxicity test, tarragon oil exhibited 100% and 90% fumigant toxicity against adult male German cockroaches at 5 and 2.5 mg/filter paper, respectively. Fumigant toxicities of Artemisia arborescens and santolina oils against adult male German cockroaches were 100% at 20 mg/filter paper, but were reduced to 60% and 22.5% at 10 mg/filter paper, respectively. In contact toxicity tests, tarragon and santolina oils showed potent insecticidal activity against adult male German cockroaches. Components of active oils were analyzed using gas chromatography, gas chromatography-mass spectrometry, or nuclear magnetic resonance spectrometer. Among the identified compounds from active essential oils, estragole demonstrated potent fumigant and contact toxicity against adult German cockroaches. β-Phellandrene exhibited inhibition of male and female German cockroach acetylcholinesterase activity with IC50 values of 0.30 and 0.28 mg/mL, respectively.
测定了 16 种菊科植物精油及其成分对成年雄性和雌性德国蟑螂的熏杀和接触毒性。在熏杀毒性试验中,龙蒿油对成年雄性德国蟑螂的熏杀毒性分别为 100%和 90%,在 5 和 2.5 mg/滤纸时。迷迭香和圣塔琳娜油对成年雄性德国蟑螂的熏杀毒性均为 100%,在 20 mg/滤纸时,但分别降低至 60%和 22.5%。在接触毒性试验中,龙蒿和圣塔琳娜油对成年雄性德国蟑螂表现出很强的杀虫活性。使用气相色谱、气相色谱-质谱或核磁共振谱仪分析活性油的成分。从活性精油中鉴定出的化合物中,莪术烯对成年德国蟑螂具有很强的熏杀和接触毒性。β-蒎烯对雄性和雌性德国蟑螂乙酰胆碱酯酶活性的抑制作用的 IC50 值分别为 0.30 和 0.28 mg/mL。
