  1. Calculated monthly biting rates (MBR) of host-seeking blackflies by locality, season, trapping technique and species: aBosomase in the Dry season in 2011 for one day, V/C =2 S. sanctipauli =61bites/month/person; bGyankobaa in the Dry season in 2010 for 7 hrs, Cow-Tent =2 S. damnosum s.s./S. sirbanum =96flies/month/cow; cS. damnosum s.l. column equates to the total MBR for all species combined and is directly comparable with previous studies which have not split the data between species.
