Abstract
|
|
|
|
The oils of Acorus gramineus Cinnamomum sieboldii Eugenia aromatica and Inula helenium were tested for their acaricidal activity against Dermatophagoides farinae and D. pteronyssinus. Responses varied according to dose and mite species. As compared to the oils the oil most toxic to D. farinae and D. pteronyssinus was E. aromatica followed by C. sieboldii A. gramineus and I. helenium. On the basis of LD50 values of the oils in A. gramineus C. sieboldii and E. aromatica the compound most toxic against D. farinae and D. pteronyssinus was eugenol congeners (isoeugenol>eugenol> acetyleugenol) followed by benzyl benzoate salicylaldehyde safrol DEET cinnamyl alcohol and 3-carene. As a naturally occurring acaricide these oils and eugenol congeners could be useful as new acaricidal agents against Dermatophagoides spp.
