Comparative larval anatomy of the digestive system of three Calliphoridae (Diptera) species that cause different types of myiasis

The Calliphoridae are one of the main Diptera families that include agents of the parasitic disease condition known as myiasis. Parasitism seems to have evolved multiple independent times within the Calliphoridae; consequently, this family includes a diversity of myiasis-causing species, varying in...

description The Calliphoridae are one of the main Diptera families that include agents of the parasitic disease condition known as myiasis. Parasitism seems to have evolved multiple independent times within the Calliphoridae; consequently, this family includes a diversity of myiasis-causing species, varying in their obligate or facultative habits and in their specific location in the host. Larval morphological studies can provide novel and relevant insights into the biology of those species, as well as on the pathogenesis and evolution of myiasis; however, the anatomy of internal organs and structures — particularly those within the digestive system— has generally been overlooked, despite potentially reflecting parasitic adaptations.
