Direct And Indirect Effects Of Animal Detritus On Growth, Survival, And Mass Of Invasive Container Mosquito Aedes Albopictus (Diptera : Culicidae, Donald A. Yee, Banugopan Kesavaraju, Steven A. Juliano Jul 2007

Direct And Indirect Effects Of Animal Detritus On Growth, Survival, And Mass Of Invasive Container Mosquito Aedes Albopictus (Diptera : Culicidae, Donald A. Yee, Banugopan Kesavaraju, Steven A. Juliano

Faculty Publications – Biological Sciences

Compared with plant detritus, animal detritus yields higher growth rates, survival, adult mass, and population growth of container-dwelling mosquitoes. It is unclear whether the benefit from animal detritus to larvae results from greater microorganism growth, direct ingestion of animal detritus by larvae, or some other mechanism. We tested alternative mechanisms by which animal detritus may benefit the invasive container-dwelling mosquito Aedes albopictus (Skuse) (Diptera: Culicidae). In the laboratory, larvae were reared under three conditions with access to 1) detritus, but where microorganisms in the water column were reduced through periodic flushing; 2) water column microorganisms, but larvae had no direct …


Taxonomy Of The Species Of Amphigerontia (Psocoptera : Psocidae) Of The Rocky Mountains Of The United States And Canada, Edward L. Mockford, Johannes E. Anonby Jul 2007

Taxonomy Of The Species Of Amphigerontia (Psocoptera : Psocidae) Of The Rocky Mountains Of The United States And Canada, Edward L. Mockford, Johannes E. Anonby

Faculty Publications – Biological Sciences

Five species of psocids of the genus Amphigerontia Kolbe 1880, are recorded from the Rocky Mountains of the United States and Canada. Amphigerontia longicauda, n. sp., is described. Amphigerontia petiolata (Banks) is recorded from the Rocky Mountains for the first time. The holotype of Amphigerontia infernicola (Chapman) is re-examined and described in detail. New characters for the separation of females of Amphigerontia bijasciata (Latreille) and Amphigerontia montivaga (Chapman) resulted in many new records of the latter species, previously known in the Rocky Mountains from only a single locality. Species-level characters are reviewed and several new ones are added. A key …

Interspecific And Intraspecific Differences In Foraging Preferences Of Container-Dwelling Mosquitoes, Kesavaraju Banugopan, Donald A. Yee, Steven A. Juliano Mar 2007

Interspecific And Intraspecific Differences In Foraging Preferences Of Container-Dwelling Mosquitoes, Kesavaraju Banugopan, Donald A. Yee, Steven A. Juliano

Faculty Publications – Biological Sciences

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 …
