| blood feeding and autogeny in the peridomestic mosquito aedes bahamensis (diptera: culicidae). | under laboratory conditions, most colony and field-collected aedes bahamensis berlin females developed eggs autogenously when they had access to sugar. however, significantly fewer starved females were autogenous, and they produced smaller egg clutches. autogenous fecundity covaried with wing length, and smaller females generally failed to express autogeny. mating had no effect on the maturation of the initial egg clutch. most starved, nulliparous females blood fed from a restrained host. at a s ... | 1993 | 8459415 |
| ecology of invasive mosquitoes: effects on resident species and on human health. | investigations of biological invasions focus on patterns and processes that are related to introduction, establishment, spread and impacts of introduced species. this review focuses on the ecological interactions operating during invasions by the most prominent group of insect vectors of disease, mosquitoes. first, we review characteristics of non-native mosquito species that have established viable populations, and those invasive species that have spread widely and had major impacts, testing wh ... | 2005 | 17637849 |

| aedes bahamensis: its invasion of south florida and association with aedes aegypti. | the exotic mosquito, aedes bahamensis, is now well-established in south florida, where it is widely distributed throughout dade and southern broward counties in both urban and rural areas east of the everglades. when discarded automobile tires were sampled in areas near human habitation, larvae and pupae of ae. bahamensis were frequently found in association with immature ae. aegypti. elsewhere, however, ae. bahamensis generally occurred in the absence of ae. aegypti. the persistence of ae. baha ... | 1989 | 2708981 |
| preliminary studies of aedes bahamensis as a host and potential vector of st. louis encephalitis virus. | aedes bahamensis, a recent introduction to the state of florida, was studied to determine its capability to serve as a host or vector of st. louis encephalitis (sle) virus. females were readily infected by inoculation, and had whole body virus titers as high as 10(9.4) mosquito infectious doses 50. sixty percent of females that had been infected by inoculation were capable of orally transmitting virus. nearly half of the females feeding on viremic chickens became infected, but not all of these i ... | 1991 | 2045810 |
| key characters for identifying aedes bahamensis and aedes albopictus in north america, north of mexico. | aedes bahamensis, a species recently introduced into southern florida represents the first member of the subgenus howardina to be found in the united states. its separation from all other nearctic aedes is the subject of this work, integrating it into the north american mosquito keys (darsie and ward 1981). the key revisions presented are expanded to include the other exotic species now found in the united states, aedes albopictus. | 1992 | 1402873 |
| differential survivorship of invasive mosquito species in south florida cemeteries: do site-specific microclimates explain patterns of coexistence and exclusion? | within 2 yr of the arrival of the invasive container mosquito aedes albopictus (skuse), the previously dominant invasive mosquito aedes aegypti (l.) disappeared from many florida cemeteries. at some cemeteries, however, ae. aegypti populations seem stable despite ae. albopictus invasion. we sought to understand this variation in the outcome (exclusion, coexistence) of this invasion, given that previous experiments show that ae. albopictus is the superior larval competitor. we tested experimental ... | 0 | 20852732 |
| environmental and genetic factors determine whether the mosquito aedes aegypti lays eggs without a blood meal. | some mosquito strains or species are able to lay eggs without taking a blood meal, a trait named autogeny. this may allow populations to persist through times or places where vertebrate hosts are scarce. autogenous egg production is highly dependent on the environment in some species, but the ideal conditions for its expression in aedes aegypti mosquitoes are unknown. we found that 3.2% of females in a population of ae. aegypti from kenya were autogenous. autogeny was strongly influenced by temp ... | 2015 | 25646251 |
| larval competition between aedes japonicus and aedes atropalpus (diptera: culicidae) in simulated rock pools. | the success of an invasive species becoming established in a new region often depends on its interactions with ecologically similar resident species. the propensity of the newly-established mosquito aedes japonicus to inhabit rock pools throughout the eastern united states provides a natural setting for interspecific larval competition with the native aedes atropalpus. a laboratory experiment conducted in simulated rock pools to evaluate larval interactions between and within these two species s ... | 0 | 19263842 |
| sensory aspects of host location in mosquitoes. | visual, thermal and olfactory stimuli all contribute to blood meal host location in mosquitoes but olfaction is probably the dominant sensory modality used for this purpose. much attention has been devoted to the l-lactic acid receptor because it is well characterized and because its sensitivity is a major determinant of host responsiveness in the anautogenous species aedes aegypti. studies employing statistical analysis of close to 500 single unit recordings and the scanning electron microscope ... | 1996 | 8894299 |
