Abstract

There were three patterns of dispersal of postfeeding larvae in 8.1-m-long channels in the laboratory. Phaenicia sericata (Meigen) and Calliphora vicina (Robineau-Desvoidy) were the most mobile, with >99 and 84.5%, respectively, moving 3–8.1 m from the food. Larvae of Phormia regina (Meigen), Chrysomya rufifacies (Macquart), and the muscid Muscina stabulans (Fall;én) dispersed the least. Only 2% of Phormia regina, 10% of M. stabulans, and 16% of C. rufifacies moved away from the food. Larvae of Cochliomyia macellaria (F.) were intermediate; 40% remained at the food, about 50% dispersed up to 2.4 m, and none went beyond 5.1 m. Evidence is presented and evaluated that suggests that postfeeding larvae of Calliphorinae move farther from the food source, pupariate underground, and produce a thinner puparium followed by a longer pupation period, than larvae of Chrysomyinae.
