Temperature Effects on the Immature Development Time of Culex eduardoi Casal & García (Diptera: Culicidae)

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.
