A survey of adult mosquitoes in the area Palmar dam, Uruguay, was conducted from October 1980 to March 1981, prior filling reservoir. The Culicidae fauna consisted 22 species 7 genera: Aedeomyia Theobald, Aedes Meigen, Anopheles Culex Linnaeus, Mansonia Blanchard, Psorophora Robineau-Desvoidy and Uranotaenia Lynch-Arribálzaga; most diverse genera being (subgenus Ochlerotatus Lynch-Arribálzaga),...

Breeding populations of Ochlerotatus japonicus japonicus, 1st detected in 1998, are now found in several states in the United States. To be able to identify this mosquito with the keys to the mosquitoes of North America north of Mexico, changes are proposed, especially dealing with the new genus Ochlerotatus. Also, a checklist of the genera Ochlerotatus and Aedes in the Nearctic Region is given.

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...

The effect of multiple immersions on Haemagogus janthinomys , Haemagogus leucocelaenus , Aedes albopictus and Ochlerotatus terrens eggs was studied. Eggs were collected in April, June, October and December of 2011 in Minas Gerais, Brazil. Most of the Aedes and Ochlerotatus eggs hatched upon the first immersion, while Haemagogus eggs showed a varied instalment hatching response. The number of im...

This study was conducted as part of a field ecology study of arboviral activity in the Amazon Basin, Peru, to determine the taxonomy, frequency, seasonal, and vertical distributions of potential mosquito vectors. In addition, the relative efficiency of human-landing collections and dry ice-baited Centers for Disease Control (CDC)-type light traps was determined for collecting mosquitoes. A tota...

We report the characterization of three novel flaviviruses isolated in Spain. Marisma Mosquito virus, a novel mosquito borne virus, was isolated from Ochlerotatus caspius mosquitoes; Spanish Ochlerotatus flavivirus and Spanish Culex flavivirus, two novel insect flaviviruses, were isolated from Oc. caspius and Culex pipiens, respectively. During this investigation, we designed a sensitive RT-nes...

To classify mosquito species based on common features of their habitats, samples were obtained fortnightly between June 2001-October 2003 in the subtropical province of Chaco, Argentina. Data on the type of larval habitat, nature of the habitat (artificial or natural), size, depth, location related to sunlight, distance to the neighbouring houses, type of substrate, organic material, vegetation...

Many species of Culicidae are of major medical, veterinary, and economic importance. To facilitate discussion among taxonomists, medical entomologists, ecologists, and vector control specialists, it is essential that culicidologists be able to readily recognize individual genera. Adult female mosquitoes, the stage most often encountered in surveys, should be identifiable to genus without dissec...

We explored how inter- and intra-specific competition among larvae of two temporary-pool mosquito species, Culiseta longiareolata and Ochlerotatus caspius, affect larval developmental strategy and life history traits. Given that their larvae have similar feeding habits, we expected negative reciprocal inter-specific interactions. In a microcosm experiment, we found sex-specific responses of lar...

Two hundred and ten isolations of West Nile virus (WNV) were obtained from 17 mosquito species in six genera in statewide surveillance conducted in Connecticut from June through October, 1999-2003. Culex pipiens (86), Culex salinarius (32), Culex restuans (26), Culiseta melanura (32), and Aedes vexans (12) were implicated as the most likely vectors of WNV in the region based on virus isolation ...
