We surveyed 792 larval and 12,400 adult Coquillettidia perturbans for mermithid nematodes in 1990. Collections were made from cattail marshes in the greater Boston area. No mermithids were found in the adult mosquitoes, nor in larvae collected in mid-season, but 3 were found in larvae collected during September and October. This is only the second recorded occurrence of mermithids in Cq. pertur...

Illustrated keys for the identification of fourth-instar larvae and adult females of seven genera of mosquitoes are presented, along with the geographic distribution of each species and the known immature habitats. Sixty-seven mosquito species belonging to genera Aedeomyia, Ficalbia, Mimomyia, Hodgesia, Coquillettidia, Mansonia, and Uranotaenia are recognized in Thailand. Hodgesia bailyi and Ur...

Mermithid parasites (Nematoda: Mermithidae) were observed in 11 mosquito species in 22 counties of Indiana, Michigan, Minnesota, Ohio and Wisconsin. Natural hosts included adult Aedes vexans, Ae. canadensis, Ae. cinereus, Ae. diantaeus, Ae. punctor, Anopheles punctipennis and Coquillettidia perturbans and larvae of Ae. abserratus, Ae. canadensis, Ae. cinereus, Ae. communis, Ae. diantaeus, Ae. p...

Putative epidemic/epizootic eastern equine encephalomyelitis virus (EEE) vector populations were compared at 15 recent (1982-90) human and horse case sites in Bristol and Plymouth counties in southeastern Massachusetts. Carbon dioxide-baited American Biophysics Corporation light traps were used for trapping adult mosquitoes to estimate biting risk in these foci of known transmission. Population...

The ecology of mosquitoes were studied (Diptera: Culicidae) in areas of Serra do Mar State Park, State of São Paulo, Brazil. Systematized monthly human bait collections were made three times a day, for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (January 1991 to December 1992). A total of 24, 943 specimens of adult mosquitoes belonging to 57 species were coll...

in the previous studies by foreign investigators on culicinae fauna of iran two culiseta, cs. longiareolata and cs. annulata; one coguillettidia, cog. richiardii, and one uranotaenia species, ur. unguiculata have been reported. in the comprehensive study of the culicinae fauna of iran, made by the school of public health, teheran university, since 1980, not only all named species, except one, w...

Entomological surveys were carried out in the rubber plantation belt of Kerala to record mosquito fauna. Samples were collected from 23 randomly selected localities using standard methods for a period of three years, from Feb- ruary 2008 to January 2011. Thirty-two species belonging to nine genera: Aedes, Anopheles, Armigeres, Coquillettidia, Culex, Heizmannia, Mansonia, Toxorhynchites, and Ura...

Coquillettidia perturbans (Walker) has been implicated as a bridge vector of eastern equine encephalomyelitis virus in North America. Eastern equine encephalomyelitis virus epizootics occur regularly in wild birds in New Jersey with little or no involvement of susceptible dead end hosts even though high populations of Cq. perturbans are present. Several factors may limit eastern equine encephal...

The response of Aedes albopictus to the BG-Sentinel, Omni-directional-Fay-Prince, and Mosquito MagnetX traps was evaluated in four suburban and four sylvatic habitats in north-central Florida to ascertain potential height preference of this species. These traps, which are primarily designed to attract diurnal mosquitoes, were set at 1 and 6 m and were evaluated during 40 trapping periods over 4...

The phylogenetic relationships of Culicidae native to the northeastern United States were investigated by analyzing small subunit ribosomal DNA (18S rDNA) sequences obtained from 39 species representing nine genera. Molecular phylogenies were consistent with traditional classifications based on morphological characters except for the placements of Psorophora Robineau-Desvoidy and Uranotaenia Ly...
