[Acaricidal activity of clove bud oil against Dermatophagoides farinae (Acari: Pyroglyphidae)].
Volatile oil from the clove bud was extracted by petroleum ether using Soxhlet Extractor. The acaricidal activity was examined using direct contact and vapour phase toxicity bioassays. In a filter paper contact toxicity bio-assay, at 2.5 h after treatment, clove bud oil at a dose of 12.20 microg/cm2 killed all dust mites. As judged by 24-h LD50 values, potent fumigant action was observed with clove bud oil (12.20 microg/cm2), showing an adequate acaricidal activity against indoor Dermatophagoides farinae.
