A mark-recapture technique was used to estimate daily populations of host-seeking Tabanus abactor Philip. Daily population estimates were calculated for 31 and 37 d for areas of 2.1 km2 and 4.6 km2 for 1982 and 1983, respectively. In 1982, population estimates ranged from 22,767 to 2,125,322 flies/2.1 km2 per d with a mean of 467,277 flies/d. In 1983, population estimates ranged from 48,962 to 2,794,389 flies/4.6 km2 per d with a mean of 759,616 flies/d. The estimated average number of host-seeking females per hectare was 2,225 (0.22 flies/m2) and 1,651 (0.17 flies/m2) for 1982 and 1983, respectively. Although daily population estimates fluctuated greatly, primarily because of fluctuation in recapture rates, seasonal trends during both years were similar. The estimates calculated in this study appear to be representative of the population of T. abactor in northcentral Oklahoma based on previous studies determining seasonal abundance.
采用标记重捕技术估算寻找宿主的菲利普虻（Tabanus abactor Philip）的日种群数量。分别于1982年和1983年对面积为2.1平方千米和4.6平方千米的区域进行了31天和37天的日种群数量估算。1982年，每2.1平方千米每日的种群数量估算值在22,767只至2,125,322只苍蝇之间，平均为467,277只苍蝇/天。1983年，每4.6平方千米每日的种群数量估算值在48,962只至2,794,389只苍蝇之间，平均为759,616只苍蝇/天。1982年和1983年，每公顷寻找宿主的雌蝇估计平均数分别为2,225只（0.22只/平方米）和1,651只（0.17只/平方米）。尽管日种群数量估算值波动很大，主要是由于重捕率的波动，但这两年的季节趋势相似。基于以往确定季节性丰度的研究，本研究计算出的估算值似乎代表了俄克拉荷马州中北部菲利普虻的种群数量。
