Abstract

•C. rufifacies’ length and weight over time was non-linear.•Rate of weight gain was statistically different between tissues.•Porcine reared flies emerged 44 and 78 h after equine and canine reared flies.•Within a temperature, each tissue had similar times to complete all stages.

The hairy maggot blow fly, Chrysomya rufifacies (Diptera: Calliphoridae), is a forensically important fly often encountered on human and other vertebrate remains in temperate and tropic regions throughout the world including Australia, Asia, Central America and North America. C. rufifacies was reared under controlled laboratory conditions on three muscle types (i.e., porcine, equine and canine) at three temperatures (i.e., 20.8, 24.8 and 28.3 °C). Rate of larval weight gain across time was statistically significant between muscle types (P ≤ 0.0001) and approaching significance across time between temperatures (P = 0.0511). This research represents the first development study for C. rufifacies from central Texas, USA and the first study to examine the impact of tissue type on its development. Furthermore, these data, when compared to those available in the literature, indicate developmental differences that could be due to genetic differences in populations or possibly methods employed during the studies. Caution should be emphasized when applying development data for this species from one region to forensic investigations in other ecoregions as such differences in development based on tissue fed upon by larvae, population genetics, and methodologies used in the studies could represent error in estimating the time of colonization.
