title: [Competition between Aedes aegypti and Aedes albopictus larvae in the laboratory].
abstract: This study had the aim of evaluating the effects of intra and interspecies larval competition between Aedes aegypti and Aedes albopictus, survival of larvae time taken to develop and wing length. The experiment was carried out with three densities and five proportions of the species. Aedes aegypti survival was greater than Aedes albopictus survival at intermediate density, while it was lower at high density. Only the time taken for Aedes albopictus to develop was affected. The differences found in comparing the species combinations demonstrated that the mean wing length of Aedes aegypti was generally greater than that of Aedes albopictus. For both species, competition had greater effect on wing length and survival than on the time taken to develop. Aedes aegypti seems to present better competitive capacity than does Aedes albopictus, at intermediate density.
