| west nile virus infection rates and avian serology in east-central illinois. | understanding the geographic role of different species of mosquito vectors and vertebrate hosts in west nile virus (wnv) transmission cycles can facilitate the development and implementation of targeted surveillance and control measures. this study examined the relationship between wnv-antibody rates in birds and mosquito infection rates and bloodfeeding patterns in east-central illinois. the earliest detection of wnv-rna by reverse transcription-polymerase chain reaction taqman was from culex r ... | 2013 | 23923325 |
| the culex pipiens complex in the mississippi river basin: identification, distribution, and bloodmeal hosts. | members of the culex pipiens complex are the primary vectors of st. louis encephalitis virus and west nile virus in the mississippi river basin (mrb). the cx. pipiens complex in the mrb is composed of 4 taxa: cx. p. pipiens form pipiens, cx. p. quinquefasciatus, hybrids between cx. p. pipiens f. pipiens and cx. p. quinquefasciatus, and cx. p. pipiens form molestus. three studies on bloodmeal hosts with large sample sizes have been conducted on members of the cx. pipiens complex in the mrb includ ... | 2012 | 23401948 |
| nestling passerines are not important hosts for amplification of west nile virus in chicago, illinois. | nestling birds have been hypothesized to be important hosts for mosquito-borne arboviruses, but the role of nestlings for west nile virus (wnv) amplification remains unclear. we sampled open-cup and cavity-nesting passerines in chicago, illinois, an area of intense wnv transmission, to determine infection rates in nestlings and mosquitoes, and to test whether mosquitoes are attracted to nesting birds. analysis of culex pipiens mosquito populations demonstrated wnv amplification to high mosquito ... | 2008 | 18759639 |
| effects of restoring oak savannas on bird communities and populations. | efforts to restore and maintain oak savannas in north america, with emphasis on the use of prescribed fire, have become common. little is known, however about how restoration affects animal populations, especially those of birds. i compared the breeding densities, community structure, and reproductive success of birds in oak savannas maintained by prescribed fire (12 sites) with those in closed-canopy forests (13 sites). all sampling was conducted in illinois (u.s.a.). of the 31 bird species ana ... | 2006 | 16903107 |
| vector-host interactions of culex pipiens complex in northeastern and southwestern usa. | studies on the vector-host interactions of culex pipiens complex mosquitoes by sequencing portions of mitochondrial cytochrome b gene indicate that cx. p. pipiens f. pipiens predominantly feed on avian hosts (93.1%), and focus feeding activity on several key bird species, in particular the american robin, the gray catbird, and the house sparrow in connecticut. however, cx. p. quinquefasciatus indiscriminately feed on both birds and mammals. culex p. quinquefasciatus in harris county - texas and ... | 2012 | 23401953 |

| avian host community structure and prevalence of west nile virus in chicago, illinois. | vertebrate host diversity has been postulated to mediate prevalence of zoonotic, vector-borne diseases, such that as diversity increases, transmission dampens. this "dilution effect" is thought to be caused by distribution of infective bites to incompetent reservoir hosts. we quantified avian species richness, avian seroprevalence for antibodies to west nile virus (wnv), and infection of wnv in culex mosquitoes, in the chicago metropolitan area, illinois, usa, a region of historically high wnv a ... | 2009 | 19034529 |
