Stable isotope analysis of larval mosquito diets in agricultural wetlands in the coastal plain of Georgia, U.S.A.

Previous studies have used C and N isotope ratios to investigate the use of different food resources such as plant and animal detritus by container-breeding mosquitoes. This study is the first to report on the potential food resources assimilated by larval mosquitoes in agricultural and reference wetlands. Larval mosquitoes (Diptera: Culcidae) were sampled, along with their potential food resources, from agricultural and reference wetland habitats throughout a seasonal hydroperiod.

Nutrient enrichment affects immature mosquito abundance and species composition in field-based mesocosms in the coastal plain of Georgia.

This study is the first to examine the relationship between nutrient enrichment and oviposition preference as measured by larval mosquito abundance using field-based mesocosms adjacent to wetlands in the Gulf Coastal Plain of Georgia. Agricultural wetlands in this region are known to have higher levels of nutrients and suspended sediments compared with forested wetlands, and previous studies have shown differences in mosquito communities in agricultural and forested wetlands. The purpose of this study was to determine whether nutrient enrichment contributes to the differences in mosquito oviposition preferences as reflected by larval mosquito presence and abundance in wetlands.

Weather and landscape factors associated with adult mosquito abundance in southwestern Georgia, U.S.A.

Mosquito community composition and population dynamics were compared to weather variables and land use/cover data during 2008 to determine which variables affected population dynamics at the J.W. Jones Ecological Research Center in southwestern Georgia.

West Nile virus epizootiology in the southeastern United States, 2001.

We investigated mosquito and bird involvement in West Nile virus (WNV) transmission in July 2001 in Jefferson County, FL, and Lowndes County, GA. We detected 16 WNV-infected pools from Culex quinquefasciatus, Cx. salinarius, Cx.

Field evaluation of a new surveillance trap in Sweden.

Field tests were conducted to assess the effectiveness of American Biophysics Counterflow 2000 (CF2000) traps compared to CO2-baited Centers for Disease Control (CDC) miniature traps at a site in central Sweden. Adult mosquitoes representing 17 species and 6 genera were collected in July and August 1998. Although the 2 trap types did not differ significantly in total number of adult female mosquitoes collected, CF2000 traps captured a greater diversity of mosquito species and significantly more adult males than did CDC traps.
