| attraction of culex pipiens/restuans (diptera: culicidae) mosquitoes to bird uropygial gland odors at two elevations in the niagara region of ontario. | in an effort to determine whether female culex pipiens l. and culex restuans theobald mosquitoes (diptera: culicidae) are attracted to crow, corvus brachyrhynchus, uropygial gland secretions, cdc miniature light traps (baited with co2 but with the lights removed) were placed at approximately 1.5- and 5-m elevations, in 10 trees in awoodlot near niagara falls, canada. these traps were assigned either a bird odor or a blank control. bird odors were created by attaching cotton swabs coated with cro ... | 2005 | 15962778 |
| the impact of weather conditions on culex pipiens and culex restuans (diptera: culicidae) abundance: a case study in peel region. | mosquito populations are sensitive to long-term variations in climate and short-term variations in weather. mosquito abundance is a key determinant of outbreaks of mosquito-borne diseases, such as west nile virus (wnv). in this work, the short-term impact of weather conditions (temperature and precipitation) on culex pipiens l.-culex restuans theobald mosquito abundance in peel region, ontario, canada, was investigated using the 2002-2009 mosquito data collected from the wnv surveillance program ... | 2011 | 21485391 |
| west nile virus infection rates in pooled and individual mosquito samples. | the detection of west nile virus (wnv) in mosquitoes by real-time rt-pcr provides valuable information on the epidemiology of the virus and identifies mosquito species that are potential vectors. testing sets of pooled mosquitoes of the same species is logistically the easiest and most cost-effective approach for wnv testing; however, little information is available on how the results of small pooled sets relate to those of testing individual mosquitoes. during the 2002 outbreak, we compared poo ... | 2004 | 15631063 |

| virus isolations from mosquitoes in southern ontario, 1976 and 1977. | following the 1975 epidemic of st. louis encephalitis (sle) in ontario, programs were instituted to monitor virus activity in mosquito populations during 1976 and 1977. mosquitoes were trapped with cdc light traps and co2 cone traps, pooled by species, and tested for virus by intracerebral inoculation of suckling mice. in 1976, 51 175 mosquitoes were tested. sle virus was isolated from two mixed pools of culex pipiens--c. restuans mosquitoes. five isolations of california serogroup viruses were ... | 1980 | 6103747 |
| ultrastructural features of cystic and merogonic stages of hepatozoon sipedon (apicomplexa: adeleorina) in northern leopard frogs (rana pipiens) and northern water snakes (nerodia sipedon) from ontario, canada. | the cystic and merogonic stages of the haemogregarine hepatozoon sipedon, infecting northern water snakes (nerodia sipedon sipedon) and northern leopard frogs (rana pipiens), respectively, in ontario, canada, were investigated by transmission electron microscopy. cysts, which were observed in the liver of northern leopard frogs (rana pipiens) after these anurans ingested mosquitoes (culex pipiens) containing oocysts of the parasite, harboured two cystozoites, each of which contained a large crys ... | 1998 | 9703677 |
