TEMPERATURE REQUIREMENTS OF CHRYSOMYA-ALBICEPS (WIEDEMANN, 1819) (DIPTERA, CALLIPHORIDAE) UNDER LABORATORY CONDITIONS

Chrysomya albiceps specimens were obtained from colonies established w ith larvae and adults collected at the Federal Rural University in Rio de Janeiro, Seropedica, State of Rio de Janeiro. The larval stage of C. albiceps was allowed to develop in climatic chambers at temperature s of 18, 22, 27 and 32 degrees C, and the pupal stage was allowed to d evelop at 22, 27 and 32 degrees C (60 +/- 10% RH and 14 hr photoperiod ). The duration and viability of the larval stage of C. albiceps at 18 , 22, 27 and 32 degrees C were 21.30, 10.61, 5.0 and 4.0 days and 76.5 , 88.5, 98.5 and 99.5%, respectively, with mean mature larval weights of 45.16, 81.86, 84.35 and 70.53 mg, respectively. Mean duration and v iability of the pupal stage at 22, 27 and 32 degrees C were 9.36, 4.7 and 3.0 days and 93.8, 100 and 100%, respectively. The basal temperatu re for the larval and pupal stage and for the larval and adult phase w ere 15.04, 17.39 and 15.38 degrees C, corresponding to 65.67, 44.15 an d 114.23 DD.
