| Abstract |
Total developmental time of Sarcophaga dux Thomson from first -instar larvae to adult emergence was 51.8, 33.0, 25.0, 16.4, 13.6 and 15.1 days when reared at temperatures of 16, 20, 24, 28, 32 and 36 oC, respectively. There were no significant differences in developmental time between the two sexes (p>0.05). Estimates of the lower developmental threshold temperatures (tL) were 5.9, 12.9 and 11.0 oC and the thermal constants (K) were 163.2, 143.0 and 289.1 degree-days (DD) for larvae, pupae and total developmental time, respectively. The highest proportion of total mortality for larvae and pupae was recorded at 16 and 36 oC. The flies reached their maximum weights in pupal and adult stages at 20 and 24 oC, whereas minimal weights were recorded at 16 and 36 oC. At all temperatures, the mean adult weight, was smaller in females than in males. The optimal temperature in terms of rapid development, low mortality, and greatest weight ranged between 20 and 28 oC. |
