Testing Predictions of Displacement of Native Aedes by the Invasive Asian Tiger Mosquito Aedes Albopictus in Florida, USA

摘要: The Asian Tiger Mosquito Aedes albopictus arrived in the USA 1985 used automobile tires from Japan and became established Texas. This species has since spread to become most abundant container-inhabiting mosquito southeastern USA, including Florida, where it reduced range of another non-indigenous mosquito, aegypti. To assess accuracy predictions that A. would competitively exclude native Eastern Treehole triseriatus but not treeholes (Livdahl Willey (1991) Science 253: 189–191), we extensively monitored abundances immatures before after invaded these habitats south Florida. These field data failed demonstrate exclusion following establishment this microhabitat 1991. However, had significantly higher metamorphic success showed a significant increase mean crowding on 1991 1999. In urban suburban sites, was uncommon abandoned even arrival albopictus. some wooded there is evidence for decline numbers cemetery vases, been excluded habitats. Overall, negative effect less severe than Experiments outdoors surrogate more successful survival emergence presence predatory larvae Toxorhynchites rutilus when first instar predators encountered both prey shortly their hatch. Eggs also hatched rapidly those triseriatus, giving invasive an initial developmental advantage escape predation. Biological traits may favor are offset partly by greater treehole occupancy infrequency undisturbed woodlands, which mitigates against displacement
