Population dynamics of Lutzomyia shannoni were monitored from April 1986 through December 1987 on Ossabaw Island, Ga. Most (99%) of the 19,788 adult sand flies were collected in light traps supplemented with dry ice; less than or equal to 1% were aspirated from diurnal resting sites. Adult sand flies first appeared in April and were followed by peaks of abundance during May 1986, and May and July 1987. Numbers of adults captured fell rapidly in October and November 1986 and in September and October 1987. No specimens were collected in December 1986 or in March, November, and December 1987. Light trap catch was affected positively by mean nightly air temperature and negatively by rainfall 14 d before collection, but not by wind speed or moon phase. Vesicular stomatitis viral activity, as measured by antibodies in feral and domestic swine, roughly corresponded to the seasonal appearance of adult L. shannoni during 1986 and 1987. Significantly more adults (72%) were collected in light traps at ground level (0.5m) than at heights of 4 and 8m. Most resting adults were collected from dark, moist tree holes and cavities of various hardwoods.
1986年4月至1987年12月期间，在佐治亚州的奥萨巴岛对香农白蛉的种群动态进行了监测。19788只成年白蛉中，大部分（99%）是在补充了干冰的诱虫灯中捕获的；从日间栖息场所吸出的不到或等于1%。成年白蛉于4月首次出现，随后在1986年5月以及1987年5月和7月出现数量高峰。1986年10月和11月以及1987年9月和10月捕获的成虫数量迅速下降。1986年12月以及1987年3月、11月和12月未采集到标本。诱虫灯捕获量受夜间平均气温的正向影响，受采集前14天降雨量的负向影响，但不受风速或月相的影响。通过野生和家养猪的抗体测量的水疱性口炎病毒活性，大致与1986年和1987年成年香农白蛉的季节性出现情况相符。在地面（0.5米）高度的诱虫灯中捕获的成虫（72%）明显多于4米和8米高度的诱虫灯。大多数静止的成虫是从各种硬木的黑暗、潮湿树洞和空洞中采集到的。
