New alternative insecticides are necessary for the chemical control of head lice. In this study the fumigantknockdown time 50% (KT50) and repellency index (RI) of three aliphatic lactones was compared with two essentialoils and DDVP, against permethrin-resistance Pediculus humanus capitis from Argentina. In the fumigant assay,none of the lactones were effective compared to the highest activity of eucalyptus (KT50 15.53 m). In the repellencytest, the three lactones were equally or more effective (RI ranging from 60.50 to 76.68) than the positive control(piperonal). These lactones are promising as head lice repellents.
