  1. Effects of temperature on Chrysomya rufifacies (Diptera : Calliphoridae) development.

    Article - En anglais

    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, o°c and a constant temperature of 25.0°C. Development from egg to adult under all regimes ranged from 190 to 598 h. A constant temperature of 25°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°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.
