【 摘 要 】

In 3,178 nits of Pediculus capitis attached in different cut hair and collected from floors of bar-bershops samples in Belo Horizonte, Minas Gerais State, observations were made on the point of attaehement of these nits in relation to the cut hair segments - if in the base, middle or extremity - as well as on the state ofdevelopment of them (nits developed or empty). The direction of the operculum was assumed as a criteriumfor determining of this place. Another 66 cut hairs segments presented 140 nits in double or multiple infestations. These data can help us to estimate, roughly, the relative age of the infestation at the time of the haircut (7-10 days, in average), the time spent among consecutive reinfestations'(21-25 days, at least), as well as in that proportion the haircuts were made as a control measure for the breaking ofthe infestation (28.8%), or after the pediculosis has already been overcame (71.2%).
