Abstract

Adults could only live and reproduce to their full capacity at temperatures between 20 degrees C and 30 degrees C. At 15 degrees C the females laid no eggs, the adult life span was relatively short and the reproductive capacity of females kept at 35 degrees C was low. The thermal histories of the flies had no apparent effect on their later reactions to temperature in any of the parameters tested. The viability rates of S. calcitrans eggs exposed to temperatures between 10 degrees C and 40 degrees C exceeded 84%, but 45 degrees C was lethal. The optimum temperatures for incubation of the eggs was 30 degrees C. Pupae of S. calcitrans seemed to tolerate temperatures between 20 degrees C and 30 degrees C, but their mortalities increased markedly outside this temperature range. Tests showed that pupal mortalities increased linearly with increasing periods of exposure to a temperature of 15 degrees C.
