“…We observed rapid WNV amplification in adult mosquitoes in late July 2006 and in early August 2007. This discrepancy in timing of nesting activity compared to arbovirus transmission was also highlighted for SLE transmission in Texas (Hayes et al 1967) and California (Mahmood et al 2004). Some passerine species, including American goldfinches ( Carduelis tristis ) and indigo buntings ( Passerina cyanea ), commonly nest in the Chicago area during July and August.…”

“…mosquitoes. Previous research suggests a role for nestling birds (Hayes et al 1967) in transmission of encephalitide diseases. Experimental evidence also indicates higher host competence of nestling passerines for SLE (Mahmood et al 2004), a closely related flavivirus to WNV.…”

“…Modeling studies have suggested that nesting birds and first-year birds are important for viral amplification of eastern equine encephalomyelitis (Unnasch et al 2006). Hayes et al (1967) have suggested that nestling house sparrows ( Passer domesticus ) played a basic role in transmission of western equine encephalomyelitis. Nestlings have also been found to be competent hosts for St. Louis encephalitis (SLE), since they displayed elevated viremia after experimental infection (Mahmood et al 2004).…”

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 infection rates during both years of the study near the locations where nestlings were sampled. Nevertheless, of 194 nestlings representing 12 species, only one 8-day-old house wren was positive for WNV RNA, and only one 10-day-old mourning dove was seropositive for antibodies to WNV, but at a low titer (1:20). The number of mosquitoes captured in nest box traps and control traps was not significantly different. These combined results suggest that nestling passerines play no evident role in WNV amplification and transmission in the Chicago area.

“…2,5 If nestling birds serve as amplifying hosts (in which viruses rapidly multiply, providing an important source of pathogens for vectors), then the nesting periods of avian reservoirs should slightly precede the annual peak in the minimum infection rate observed in vector mosquitoes. 6 Despite the potential importance of nestling birds in the ecology of arboviruses, whether nestling birds play a role in natural amplification cycles of arboviruses remains a matter of debate. Various experimental techniques have been devised to determine the attractiveness of nestling birds to questing mosquitoes and the rates at which nestlings are fed upon relative to adults.…”

The hypothesis that nestlings are a significant driver of arbovirus transmission and amplification is based upon findings that suggest nestlings are highly susceptible to being fed upon by vector mosquitoes and to viral infection and replication. Several previous studies have suggested that nestlings are preferentially fed upon relative to adults in the nest, and other studies have reported a preference for adults over nestlings. We directly tested the feeding preference of nestling and adult birds in a natural setting, introducing mosquitoes into nesting boxes containing eastern bluebirds (Sialia sialis), collecting blood-fed mosquitoes, and matching the source of mosquito blood meals to individual birds using microsatellite markers. Neither nestlings nor adults were fed upon to an extent significantly greater than would be predicted based upon their relative abundance in the nests, although feeding upon mothers decreased as the age of the nestlings increased.

“…If the shed and pen are made in prefabricated panels, two men can apparently assemble, or dismantle, a trap in about an hour (Rainey et al, 1962). Hayes et al (1967) found these traps useful in studying the ecology of arboviruses in Texas, while Shemanchuk (1969) in Canada used similar traps, but modified to include an entry trap to catch mosquitoes before they could feed on the birds, and an exit trap to collect those leaving the trap. In Malaysia a sentinel chicken shed trap collected a mean of 12·02 Culex vishnui and smaller numbers of Culex quinquefasciatus (6·15) and other Culex species per day (Wallace et al, 1977).…”
