Effects of temperature on Chrysomya rufifacies (Diptera:Calliphoridae) development.
Growth curves were studied for the egg, larva, and pupa of Chrysomya rufifacies (Macquart) under mean cyclic temperatures of 15.6, 21.1, 26.7, and 35.0 degrees C and a constant temperature of 25.0 degrees C. Development from egg to adult under all regimes ranged from 190 to 598 h. A constant temperature of 25 degrees C produced a range of pupation times from 134 to 162 h, with adult emergence ranging from 237 to 289 h. The maximal preferential temperature of 35.1 degrees C was determined for maggots using a gradient system. Highly predictable developmental time, minimal larval length variation, and low cohort variation emphasize the utility of this species in entomological-based postmortem interval determinations. Therefore, C. rufifacies should be of primary forensic importance when recovered alone or in conjunction with other species of Calliphoridae.
