Peri-domestic ecology of dry-season populations of Aedes (Stegomyia) mosquitoes in Uyo, Cross River State, Nigeria
Environmental Entomology 10 (5), 592-599
Abstract: The adult insects were sampled by two collection methods: (1) crepuscular human bait and (2) sweep-netting from forest and village (outdoor and indoor) locations. Oviposition and breeding habits of the insects were assessed from CDC ovitrap collections and from a survey of larval presence in domestic and peri-domestic containers. In each case, insects were sampled in the months of November, January, March, and May, corresponding with the early, mid, and late dry season, and the early rainy season, respectively.
Fourteen species of Aedes mosquitoes, including four Aedes (Stegomyia) species, were found. Numbers and distribution of the species varied with the months and sampling methods. Adult Aedes (Stegomyia) were most numerous in indoor and outdoor crepuscular human bait collections and least in forest sweep-net collections. Aedes aegypti and A. africanus were the most collected species. Unlike most other Aedes spp., they were consistently well represented in all the dry-season samples. Larval indices owed predominant breeding of Aedes (Stegomyia) species in pendomestic locations throughout the dry season, as well as the ecological adjustment to a container breeding habit by some otherwise well-known tree hole and pool breeding forms.
Factors involved in the dry-season survival of the various Aedes spp. are discussed with reference to the possible implications of the insects' domesticity and year-round breeding activity.
