In order to elucidate the recent spread of mosquito species in the United States and Canada, a summary of new records for states and provinces has been prepared to include those reported mostly from 1981 to 1998, although some records before 1989 are also given. We are reporting 132 new records for 58 species of mosquitoes.
Mosquitoes were collected in Santa Fe and Rio Negro provinces, Argentina, in 1982-1983 during a western equine encephalitis (WEE) epizootic. Totals of 153,084 mosquitoes from Santa Fe Province and 484 from Rio Negro Province were tested for virus in 2,351 pools. Seventeen virus strains were isolated, all from Santa Fe collections, as follows: 4 WEE, 6(More)
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(More)
A checklist of 62 species of mosquitoes found in Pennsylvania is presented. In addition, new state records for 9 species are as follows: Aedes aegypti, Anopheles earlei, Culiseta minnesotae, Ochlerotatus atlanticus/Oc. tormentor, Oc. dupreei, Oc. infirmatus, Oc. thibaulti, Psorophora howardii.

An introduced, breeding population of Aedes albopictus has been established in Harris County, Texas, and several parishes in Louisiana. The problem of its identification and separation from the indigenous Nearctic mosquito fauna is addressed. Using the keys of Darsie and Ward (1981), the author offers suggested inserts which will accomplish the(More)

A revised list of the mosquito species known to occur in Mexico contains 20 genera, 37 subgenera, and 225 species. Several supraspecific categories have been described and species reassigned since the last list was published in 1956. Based on present knowledge, there are 29 species that are known only from Mexico. Eight species are deleted from the Mexican(More)
Tissue culture fluid NCTC 135 (Hank's base) was compared to water and to saline as incubation media for the detection of microfilariae of Onchocerca volvulus in skin snips. NCTC 135 allowed detection of significantly more positive persons than did water (P less than 0.001) or saline (P less than 0.05) when two snips per person were incubated for periods of(More)
We report the first finding of Culex coronator Dyar and Knab in Florida, based on multiple adult collections from several locations in the western panhandle of Florida. GPS coordinates and habitat descriptions are given and disease implications are discussed. These records extend the known distribution of Cx. coronator from six other states (Arizona,(More)
