Pheasants and chickens were compared as sentinels for monitoring the transmission of arboviruses of public health significance in Florida during 1991-93. Results suggest that pheasants are better sentinels for eastern equine encephalitis (EEE) virus. They detected virus transmission 3-6 weeks earlier in epizootic years, 2-4 times more frequently during the season, and twice as many birds within a flock seroconverted during a given week. Pheasants detected virus transmission at 2 sites during 2 interepizootic years when chickens failed. Although pheasants detected St. Louis encephalitis (SLE) virus activity somewhat later than did chickens, they had greater seroconversion rates than did chickens. Although both bird species can be used to monitor EEE and SLE viruses, pheasants are more sensitive than chickens as sentinels for EEE virus and as sensitive as chickens as sentinels for SLE virus.
1991 - 1993年期间，对雉鸡和家鸡作为哨兵监测佛罗里达州具有公共卫生意义的虫媒病毒传播情况进行了比较。结果表明，雉鸡是监测东部马脑炎（EEE）病毒的更佳哨兵。在流行年份，它们比家鸡早3 - 6周检测到病毒传播，在季节期间检测频率高2 - 4倍，且在给定周内，鸡群中发生血清转化的雉鸡数量是家鸡的两倍。在两次流行间期的两年里，家鸡未能检测到病毒传播的两个地点，雉鸡检测到了。虽然雉鸡检测到圣路易斯脑炎（SLE）病毒活动的时间比家鸡稍晚，但它们的血清转化率高于家鸡。虽然这两种禽类都可用于监测EEE和SLE病毒，但雉鸡作为EEE病毒的哨兵比家鸡更敏感，作为SLE病毒的哨兵与家鸡一样敏感。
