The effect of constant temperatures on the development time from first instar to adult emergence was studied in Culex eduardoi Casal & García reared at 7, 10, 15, 20, 25, 30 or 33°C. Data were adjusted to the linear degree-day model and the nonlinear Briére model. According to the linear model, the development time was inversely related to the rearing temperatures between 7°C and 25°C. Maximum mortality (100%) was recorded at temperatures > 30°C. According to the linear model, the development threshold temperature and thermal constant were 5.7°C and 188.8 degree days, respectively. The lower and upper threshold temperatures and the optimum temperature for the nonlinear model were -2.3, 30.0 and 28.1°C, respectively. |

Data are presented on the on diet, thermal biology, microhabitat use, reproduction and helminth infection parameters of a population of Mabuya macrorhyncha hoge, 1946 inhabiting the small island of Queimada Grande, on the southern coast of São Paulo State. The lizards were collected on November 1997 (spring) and on July 1998 (winter). Most lizards were perched above ground, mainly on herbaceous vegetation. Mean lizard body temperatures were significantly higher in spring (32.6 ± 1.9ºC) than in winter (28.5 ± 2.4ºC), as were air temperatures. Mean litter size of females was 2.7 (range 2-3). The diet was composed of a diverse array of arthropods and some small fruits. Of the 19 lizards examined, 16 (84.2%) harboured helminths. Three species of helminth (one... |
