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
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

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
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 …

Background. Within genus Drosophila, the endemic Hawaiian species offer some of the most dramatic examples of morphological and behavioral evolution. The advent of the Drosophila grimshawi genome sequence permits genes of interest to be readily cloned from any of the hundreds of species of Hawaiian Drosophila, offering a powerful comparative approach to defining molecular mechanisms of species evolution. A key step in this process is to survey the Hawaiian flies for characters whose variation can be associated with specific candidate genes. The wings provide an attractive target for such studies: Wings are essentially two dimensional, and genes controlling wing shape, …

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 …
