Ovicidal and Adulticidal Activity of Eucalyptus globulus Leaf Oil Terpenoids against Pediculus humanus capitis (Anoplura: Pediculidae)

摘要: The toxic effects of Eucalyptus globulus leaf oil-derived monoterpenoids [1,8-cineole, l-phellandrene, (−)-α-pinene, 2-β-pinene, trans-pinocarveol, γ-terpinene, and 1-α-terpineol] the known oil terpenoids (β-eudesmol geranyl acetate) on eggs females human head louse, Pediculus humanus capitis, were examined using direct contact fumigation bioassays compared with lethal activity δ-phenothrin pyrethrum, two commonly used pediculicides. In a filter paper bioassay female P. h. pediculicidal was more pronounced than either or pyrethrum basis LT50 values (0.125 vs 0.25 mg/cm2). 1,8-Cineole 2.2- 2.3-fold respectively. activities (E)-pinocarveol comparable to those pyrethrum. l-Phellandrene, 1-α-terpineol relatively less...
