The hosts that registered positive for myiasis were cattle (46.4%), dogs (15.3%), humans (14.7%), birds (12%), pigs (6%), horses (4%), and sheep (1%). Six fly species caused myiasis: Dermato- bia hominis (58%), Phaenicia spp. (20%), Cochliomyia macellaria (19%), Chrysomya rufifacies (0.4%), and mag- gots of unidentified species belonging to the Sarcophagidae (3%) and Muscidae (0.3%). With the Dubois index, was no evidence that the absence of C. hominivorax allowed an increase in the cases of facultative myiasis. Keys words: myiasis - Calliphoridae - Sarcophagidae - Oestridae - Panama The term myiasis refers to the infestation by larvae Given present factors, such as world-wide commerce of certain families of Diptera on alive vertebrates, that and climate change, it is very important to carry out sur- use these hosts for their development and cause various veys in regions around the world to determine species pathologies depending on the species that induce them diversity in families whose members can cause myiasis.
