BACKGROUND: Recent studies have focused on materials derived from plant extracts as mite control products against house dust and stored food mites because repeated use of synthetic acaricides had led to resistance and unwanted activities on non-target organisms. The aim of this study was to evaluate the acaricidal activity of materials derived from Lycopus lucidus against Dermatophagoides farinae, D. pteronyssinus and Tyrophagus putrescentiae. %26lt;br%26gt;RESULTS: TheLD50 valuesof L. lucidusoilwere2.19,2.25and8.45 mu g cm-2 againstD. farinae, D. pteronyssinusandT. putrescentiae. The acaricidal constituent of L. lucidus was isolated by chromatographic techniques and identified as 1-octen-3-ol. In a fumigant method against D. farinae, the acaricidal activity of 1-octen-3-ol (0.25 mu g cm-2) was more toxic than N, N-diethyl-m-toluamide (DEET) (36.84 mu g cm-2), followed by 3,7-dimethyl-1-octen-3-ol (0.29 mu g cm-2), 1-octen-3-yl butyrate (2.32 mu g cm-2), 1-octen-3yl acetate (2.42 mu g cm-2), 3,7-dimethyl-1-octene (9.34 mu g cm-2) and benzyl benzoate (10.02 mu g cm-2). In a filter paper bioassay against D. farinae, 1-octen-3-ol (0.63 mu g cm-2) was more effective than DEET (20.64 mu g cm-2), followedby 3,7-dimethyl-1-octen3- ol (1.09 mu g cm-2). %26lt;br%26gt;CONCLUSION: 1-Octen-3-ol and 3,7-dimethyl-1-octen-3-ol could be useful as natural agents for the management of three mite species.
