The Asian tiger mosquito, Aedes albopictus (Skuse), is perhaps the most successful invasive mosquito species in contemporary history. In the United States, Ae. albopictus has spread from its introduction point in southern Texas to as far north as New Jersey (i.e., a span of approximate to 14 degrees latitude). This species experiences seasonal constraints in activity because of cold temperatures in winter in the northern United States, but is active year-round in the south. We performed a laboratory experiment to examine how life-history traits of Ae. albopictus from four populations (New Jersey [39.4 degrees N], Virginia [38.6 degrees N], North …
Geographic Variation In Adult Survival And Reproductive Tactics Of The Mosquito Aedes Albopictus, Paul T. Leisnham, L M. Sala, Steven A. Juliano

Climate differences across latitude can result in seasonal constraints and selection on life history characters. Since Aedes albopictus (Skuse) invaded North America in the mid-1980s, it has spread across a range of approximate to 14 degrees latitude and populations in the north experience complete adult mortality due to cold winter temperatures that are absent in the south. Life table experiments were conducted to test for differences in the adult survival and reproductive schedules of Ae. albopictus females from two populations from the northern (Bloomington, IN [BL] and Manassas, VA [VA]; approximate to 39 degrees N) and southern (Tampa, FL and …

Feeding preferences of larval container-dwelling mosquitoes are not well understood. Primary production is often absent in container systems and external inputs of animal and plant detritus supply the energy base of container food webs by supporting microorganism prey for mosquitoes. We quantified the feeding preferences of Aedes albopictus (Skuse), a non-native invasive mosquito, and Ochlerotahts triseriatus (Say), a native mosquito, when given a choice of animal and plant detritus. We tested for interpopulational (Illinois versus Florida) differences in feeding preferences, and quantified each species' performance on these two detritus types. When given a choice, both species spent significantly more time …
Precipitation And Temperature Effects On Populations Of Aedes Albopictus (Diptera : Culicidae): Implications For Range Expansion, B W. Alto, Steven A. Juliano
Precipitation And Temperature Effects On Populations Of Aedes Albopictus (Diptera : Culicidae): Implications For Range Expansion, B W. Alto, Steven A. Juliano
Faculty Publications – Biological Sciences
We investigated how temperature and precipitation regime encountered over the life cycle of Aedes albopictus (Skuse) affects populations. Caged populations of A. albopictus were maintained at 22, 26, and 30 degreesC. Cages were equipped with containers that served as sites for oviposition and larval development. All cages were assigned to one of three simulated precipitation regimes: (1) low fluctuation regime - water within the containers was allowed to evaporate to 90% of its maximum before being refilled, (2) high fluctuation regime - water was allowed to evaporate to 25% of its maximum before being refilled, and (3) drying regime - …
Temperature Effects On The Dynamics Of Aedes Albopictus (Diptera : Culicidae) Populations In The Laboratory, Barry W. Alto, Steven A. Juliano
Temperature Effects On The Dynamics Of Aedes Albopictus (Diptera : Culicidae) Populations In The Laboratory, Barry W. Alto, Steven A. Juliano
Faculty Publications – Biological Sciences
We investigated how constant temperatures of 22, 24, and 26 degreesC experienced across the full life cycle affected the dynamics of caged populations of Aedes albopictus (Skuse). All cages were equipped with plastic beakers that served as sites for oviposition and larval development. We measured the per capita daily mortality and emergence rates of the adults and size of adult females, and estimated the intrinsic rate of increase (r) and asymptotic density (K) for each adult population. populations at 26 degreesC had greater intrinsic rates of increase and lower asymptotic densities than populations at 22 and 24 degreesC. Populations at …
