1. Western equine virus has been successfully transmitted in the laboratory by 3 species of mosquitoes from 2 genera not previously reported as laboratory vectors: Culex tarsalis, Culiseta inornata, and Culiseta incidens. 2. Though transmission was not demonstrated, survival of the virus for more than a few days was shown to occur in Culex stigmatosoma and Psorophora confinnis. Possibly transmi...

Larvae of Aedes aegypti, Ae. vexans and Culiseta inornata were used to study the pathogenicity of the hyphomycete fungus Tolypocladium cylindrosporum. Experiments consisted of continuous exposure of second-instar larvae to 5 concentrations of conidia at 10, 15, 20 and 25 degrees C. The 3 test species were susceptible at all temperatures tested. There was generally a direct relationship between ...

Mosquitoes, most often recognized for the microbial agents of disease they may carry, harbor diverse microbial communities that include viruses, bacteria, and fungi, collectively called the microbiota. The composition of the microbiota can directly and indirectly affect disease transmission through microbial interactions that could be revealed by its characterization in natural populations of m...

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...

there is very little information about the mosquito fauna of mahshahr district. the present study gives an overview of data on the species composition and distribution of mosquitoes in the mahshahr district, khuzestan province, southwest of iran. in order to study the mosquito fauna, the samples were collected from may to november 2012 using dipping and total catch methods from seven village...

Twenty resting shelters were set on the edge of a known Culiseta breeding habitat in four groups of five to support a 4 x 4 Latin square field experiment. Collection times were 0900, 1100, 1300, and 1500 hours and systematically rotated for the order by which each group of five boxes was collected. Mosquitoes were collected from resting shelters by chloroform anesthetization. Collections were i...

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...
