The ticks were tested at intervals, until after the onset of oviposition, in choice chambers providing two humidities. Between tests they were kept at 100, 33, or 0 % R.H. In chambers offering 100/33 % R.H. the ticks initially showed dry-preference; from three days after collection until the sixth (last) day those kept at high humidity and 25�C showed wet-preference, those kept at the lower humidities also showed wet-preference except on the fifth day.
