The preference was determined through acute preferred temperature. Maximum critical temperature and mean lethal temperature allowed to estimate thermal tolerance. The results show that acclimation temperatures higher than 14 degrees C increase both thermal preference and tolerance. However, individuals acclimatized to 22 degrees C preferred temperatures lower than their acclimation. In addition, thermal tolerance was identical between individuals acclimatized at 17 degrees C and 22 degrees C. The optimum temperature of juvenile A. scapularis was 18.7 +/- 2 degrees C and its upper and lower tolerance limit was 32.6 and 10.1 degrees C, respectively. Based on the results, we concluded that a temperature of 18.7 +/- 2 degrees C would optimize the physiological processes in juvenile A. scapularis and that temperature higher than 32.6 degrees C and lower than 10.1 degrees C would cause the immediate death of the organism.
