Sentinel pigeons, Columba livia, were installed in lard-can traps at heights of 1.5 m and 7.6-9.1 m within differing canopy cover classes in New York City. Adult mosquitoes were collected weekly from July to October 2002, as were serum samples from each pigeon. Culex pipiens L. and Culex restuans Theobald comprised 97% of mosquitoes collected and were most numerous in canopy-level, forested traps. The West Nile virus (family Flaviviridae, genus Flavivirus, WNV) seroconversion rate was significantly greater for pigeons in canopy-level traps, although seroconversions occurred concurrently with human cases in the city and were of little prognostic value to public health agencies. Our results indicate that sentinel pigeons were most effective for monitoring enzootic transmission of WNV when placed in single-sentinel caging 7.6-9.1 m above ground level.
在纽约市不同树冠覆盖等级区域，将信鸽（家鸽）放置在高度为1.5米以及7.6 - 9.1米的猪油罐诱捕器中。2002年7月至10月期间，每周收集成年蚊子，同时也采集每只鸽子的血清样本。尖音库蚊和致倦库蚊占所收集蚊子的97%，且在树冠层、树木繁茂区域的诱捕器中数量最多。树冠层诱捕器中的鸽子西尼罗河病毒（黄病毒科黄病毒属，WNV）血清转化率显著更高，尽管血清转化与该市人类病例同时发生，对公共卫生机构而言预后价值不大。我们的结果表明，将信鸽放置在离地面7.6 - 9.1米的单只哨兵笼中时，对监测西尼罗河病毒的动物间传播最为有效。
