Abstract
In room acclimatized in Experimental Frog-Farm of Fundacao Universidade Federal of Rio Grande (REURG) four flies cages were prepared, being put in each one about 5000 pupas of Musca domestica. After the birth of the flies, each flie cage received, above the trays with food (sugar and milk), a tray with substratum for posture, constituted of humidified wheat flour. Daily the substratum for posture were homogenized and distributed among 15 small trays, conditioned in acclimatized stoves and submitted to a combination of five temperatures (20, 23, 26, 29 and 32deg. C) and three substratum for the production of larvae (flours of rice, wheat and soy). The temperatures of 20, 23 and 26deg. C provided the best results of production of larvae, that decreased as temperature increased, indicating to be unnecessary the heating use in the larvae cages in places where the minimum temperature is not lower than 20deg. C. The wheat flour went the best substratum to the production of larvae of M. domestica. The largest productivity of larvae was verified in the 7th and 8th postures.
