Percentage of swallow bug pools positive for BCRV by RT-PCR in early April (end of the winter) at a cliff swallow colony site in relation to the percentage positive there the previous October (start of the winter). Circles denoted with “2” represent two sites with the same values. Percentage positive in April was significantly correlated with percentage positive in October (r = 0.63, p = 0.039, n = 13 sites). BCRV, Buggy Creek virus; RT-PCR, reverse transcription polymerase chain reaction.
