Morphological differentiation of eggs and comparative efficacy of oviposition and gravid traps for Aedes vectors at different habitats
… japonicus. To better understand the efficacy of gravid traps and oviposition traps as surveillance methods for these mosquitoes, field studies were conducted in three different habitat types. Ae. triseriatus, Ae. albopictus, Ae. japonicus, and Aedes aegypti eggs were described with the aid of …

A comparison study of gravid and under house CO2 mosquito traps in Harris County, Texas
… population. Data describing the efficacy of Gravid (GV) and Underhouse (UH) CO2 traps were analyzed to determine if there is a significant difference between these two trap types with respect to the number of mosquitoes and the variety of mosquito species caught. This study was conducted …

Detection of the bloodmeal origin of mosquitoes collected at alligator farms, and West Nile Virus activity in mosquitoes collected from alligator farms, sentinel chicken surveillance sites, and larval habitats
… we also compared the effectiveness of CDC light traps, gravid traps, and sentinel chicken box traps for collecting WNV positive mosquitoes. In all three years, we detected WNV activity in mosquito collections from sentinel chicken box traps prior to the onset of human cases, while there were no …

Ecology and Management of Riceland Mosquitoes in Africa With Special Reference to Culex Quinquefasciatus
… other rice-land mosquitoes. CO2-baited CDC light traps were superior to non-baited CDC light traps in collection of Cx. quinquefasciatus and Culex annulioris. More Cx. quinquefasciatus females were collected in grass infusion-baited gravid traps than egg rafts of this species in oviposition traps …

Oviposition Preferences for Infusion-Baited Traps and Seasonal Abundance of Culex Mosquitoes in Southwestern Virginia
… Theobald and Culex pipiens Linnaeus using ovitraps and gravid traps. Both species have been implicated as enzootic and epizootic vectors of West Nile virus (WNV) and these studies provide information on the relative abundance of gravid mosquitoes. Ovitraps were used in the summers of 2002 and …

La Crosse virus and Dirofilaria immitis: Abundance of Potential Vectors in Southwestern Virginia and the Effects of Dual Infection on Aedes albopictus and Ochlerotatus triseriatus
… species were examined in 2003 and 2004 using gravid traps. An unexpected finding was the significant increase in the abundance of Ochlerotatus japonicus. In 2003, collections were made over 192 trap nights from June to August yielding 5,879 mosquitoes of which only 24 were Oc. japonicus. In …

Forest disturbance, mosquito vector ecology and La Crosse virus dynamics in southwestern Virginia
… and high-leave shelterwood (SW)). Using gravid traps, I found that the mosquito community was resilient to logging with no significant difference in diversity or community composition across treatments. Mean number of female mosquitoes caught per trap-night declined with disturbance. FCD …
