pipiens and Culex quinquefasciatus), Culex tarsalis, Culex stigmatosoma, Culex salinarius, Culex nigripalpus, and Culex restuans
have been implicated as urban vectors of WNV (Hayes et al.
The surveillance of Culex pipiens, Culex restuans
, and Culex tarsalis mosquito species, the main vectors of WNV transmission in Minnesota, increased from 2002 onward.
The ability of Culex pipiens and Culex restuans
to locate small ovisites in the field.
The earliest species found positive for WNV were Aedes vexans, Culex pipiens, Culex restuans
, and Culex salinarius (Godsey et al.
rarely bite people, but by spreading the virus more widely through the bird population, the mosquito helps to spread it to other species that bite the infected birds and then bite people.
A recent batch of mosquitoes trapped at the Van Norman Reservoir near Granada Hills proved surprising - an ``inornata,'' a winter mosquito usually found later in the year and a culex restuans
, a mosquito species rare in California.
The larvae were identified and found to belong to five species, namely, Anopheles punctipennis, Culex restuans
, Culex territans, Ochlerotatus atlanticus, and Psorophora columbiae.
In the early part of the season, our field staff and county partners will be targeting a specific species, Culex restuans
, which we believe played a significant role in spreading the virus among birds early in the 2003 season," Secretary McGinty said.
A preliminary study of the seasonal geographic distribution and overwintering of Culex restuans
Theobald and Culex salinarius Coquillett (Diptera: Culicidae).
We hope by reducing the number of Culex restuans
early in the season, we can reduce the spread of the virus among birds, and then among humans.
Fourteen mosquito pools tested positive for WN virus: four pools of Culex restuans
, five pools of Cx.
In the early part of the season, our field staff will work with the counties to target a mosquito species, Culex restuans
, which we believe may have played a significant role in spreading the virus among birds early in the 2003 season," Secretary McGinty said.
