| 摘 要： | INTRODUCTION Among several species of the family Pyro- glyphidae, Dermatophagoides pteronyssinus and D. farinae, have been found to be the predominant mites of household dust accounting for about 80%~90% of the total mite populations and are important sources of allergens worldwide inside homes in humid geo- graphic areas (Hallas, 1991; Arlian et al., 1992). Both house dust mites are found in homes in various areas of Egypt (Rezk, 2004; Rezk et al., 1996). They are a major cause of res…

| Abstract: | The acaricidal activities of fourteen essential oils and fourteen of their major monoterpenoids were tested against house dust mites Dermatophagoides pteronyssinus. Five concentrations were used over two different time intervals 24 and 48 h under laboratory conditions. In general, it was noticed that the acaricidal effect based on LC50 of either essential oils or monoterpenoids against the mite was time dependant. The LCso values were decreased by increasing of exposure time. Clove, matrecary, chenopodium, rosemary, eucalyptus and caraway oils were shown to have high activity. As for the monoterpenoids, cinnamaldehyde and chlorothymol were found to be the most effective followed by citronellol. This study suggests the use of the essential oils and their major constituents as ecofriendly biodegradable agents for the control of house dust mite, D. pteronyssinus. |
