| Abstract | Abstract. Total developmental time of Chrysomya albiceps ( Wiedemann ) from egg to adult was 18.5, 14.1, 9.8 and 9.2 days when reared at 20, 25, 30 and 35 oC, respectively, at 15 oC all pupae did not develop to adult stage, and there were no significant differences between sexes (p>0.05). Estimates of the lower developmental threshold temperatures (tL) were 10.5, 7.7, - 11.0, 5.0, 6.7, and 5.9oC and the thermal constant (K) were 9.8, 99.8, 78.2, 159.8, 88.6 and 258.5 degree - days) ý(DD) for eggs, feeding larvae, wandering larvae, larvae (feeding+ wandering), pupae, and total developmental time, respectively. The lowest proportion of mortality was recorded at 25 and 30oC. Flies reached their maximum weight in pupal and adult stages at 25oC, whereas minimal weights were recorded at 35oC. Regardless of temperature, the mean weight of pupa and adult was smaller (p<0.001) in males than in females. The developmental rate, low mortality and greatest weight reached their optimal condition between 25 and 30oC. |
