| effect of environmental temperature on the vector competence of culex pipiens and cx. torrentium for ockelbo virus. | the effects of environmental temperature on ockelbo virus infection, dissemination, and transmission were studied in culex torrentium and in the uppsala and the el gabal strains of cx. pipiens. temperatures tested included 10 degrees c, 17 degrees c, 24 degrees c, and a cyclic (10-24 degrees c, mean = 17 degrees c) regimen designed to mimic typical hourly temperatures in an area endemic for ockelbo disease in sweden during the transmission season. the vector competence of both the uppsala and th ... | 1990 | 2173433 |
| swedish culex torrentium and cx. pipiens (diptera: culicidae) as experimental vectors of ockelbo virus. | the ability of the sibling species culex pipiens (l.) and culex torrentium (martini) from central sweden to transmit ockelbo (ock) virus was determined. both species became infected after ingesting ock virus from a viremic chicken; they transmitted this virus to chickens after 21-28 d of extrinsic incubation. in cx. torrentium, infection rates were 90% or higher, and all 10 refeeding mosquitoes transmitted virus after feeding on chickens with a viremia of at least 10(3.0) plaque-forming units (p ... | 1990 | 2167372 |
