RESUMEN
The classic episode of biological invasion: Cochliomyia macellaria (Fabricius, 1775) versus Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) - evaluation of the biotic potential. The biotic of the native fly Cochliomyia macellaria and the exotic Chrysomya megacephala was compared, through the reproductive capacity and longevity. The experiment took place in a climatized chamber, with four repetitions of 15 grouped couples of each species. The posture, egg mass weight, and death of individuals were observed daily. C. macellaria showed an average of longevity of 27.72 days while in C. megacephala the average was 41.96 days. The egg mass weight average per repetition was 0.58 g and 1.22 g, respectively. These results give a better understanding about the population dynamics of these species in nature.

Miíase é uma doença causada por larvas de dípteros que se alimentam de tecidos vivo ou necrosado de hospedeiros. Paciente ingresso em hospital público, em péssimo estado clínico geral, exibia três lesões na cabeça com miíases, das quais foram retiradas 518 larvas de C. hominivorax e duas de D. hominis. Após aretirada de larvas, o paciente foi submetido a enxerto de pele.
Myiasis is a disease caused by an infection due to invasion of tissues or cavities of the body by larvae of dipterans insects that feed on live or necrotic tissue of the hosts. A patient was admitted to a public hospital, with a very bad general clinic state, presenting three lesions in the head, from which 518 larvae of C. hominivorax and two larvae of D. hominis were removed. After the removal of the larvae, the patient was submitted to a skin graft.
