摘要:
Interspecific competition with native species during biological invasions can sometimes limit alien expansion.We aimed to determine the potential ecological effects ofLimatus durhamii Theobald 1901,a native Neotropical mosquito (Diptera:Culicidae)species,on the invasive species Aedes (Stegomyia) aegypti (Linnaeus 1762) that breeds in the same artificial water containers.Development time and adult dry mass were measured in 3 rearing conditions:control (a single larva),intraspecific competition (2 conspecific larvae),and interspecific competition (2 heterospecific larvae).Food was provided ad libitum to eliminate exploitative competition.For Ae.aegypti,development time was not affected by interspecific interference competition (nonsignificant differences with the control) and the adult dry mass was significantly higher,meaning that individual fitness likely increased.Yet,because previous studies showed longer development time and lighter adults during competition with other invasive mosquitoes,it is likely that Ae.aegypti can express a different phenotype depending on the competing species.The similar pattern found for Li.durhamii females and the nonsignificant difference with the control for males explain in part why this species can compete with Ae.aegypti.
