  abstract: Blow flies (Diptera: Calliphoridae) are carrion feeding insects that perform a critical ecological service by recycling nutrients throughout temperate and tropic regions of the world. Some members of this guild are parasites of vertebrates and important to medical and veterinary research. Given their relatively predictable life cycles and close association with carrion, estimating blow fly age from human and animal remains can also be informative in legal investigations. In the southern United States, the blow fly Cochliomyia macellaria (Fabricius), known as the secondary screwworm, is a common primary colonizer of carrion, can parasitize mammals, and often is used as evidence in forensic investigations. Accordingly, studies of this organism can contribute to our basic knowledge of decomposition ecology. Life history traits are important to the evolutionary fitness of any organism and yet, there are very few studies on genetic variation of these phenotypes in blow flies even though knowledge of that variation would aid in medical, agricultural, and forensic endeavors. Natural genetic variation in development time and body size has been observed in C. macellaria. To further evaluate genetic variation in immature development rates of this species, an artificial selection experiment was performed on three Texas populations. After 23 generations of selection at 25°C, all experimental populations selected for faster development exhibited approximately a 1.5 days decrease in mean development times as compared to the founding generation, while those bred for slow development required another 3.5 days of development. The six selected lines were subsequently reared in different thermal environments (20°C, 25°C, and 30°C), to evaluate their phenotypic plasticity in development time, pupal mass, and immature viability. Under different thermal exposures, C. macellaria developed slower at cooler temperatures and faster at warmer temperatures with a difference between selection g…
