FARIA, Lucas Del Bianco  and  GODOY, Wesley Augusto Conde. Prey choice by facultative predator larvae of Chrysomya albiceps (Diptera: Calliphoridae). Mem. Inst. Oswaldo Cruz [online]. 2001, vol.96, n.6, pp.875-878. ISSN 1678-8060.

In this study we investigated predation rates on third instar larvae of Chrysomya putoria and C. megacephala by third instar larvae of C. albiceps in a two-choice situation. The highest predation rate occurred on C. putoria larvae and this result is compared to previous experiments, in which C. macellaria larvae were present. Our results suggest that, when C. macellaria is absent C. albiceps larvae attack more C. putoria than C. megacephala larvae. Prey choice decisions and its implications for introduced and native blowflies are discussed.

Keywords : Chrysomya albiceps; prey choice; larval predation; interspecific interaction; Diptera; Calliphoridae.
