Abstract

Host-seeking activity of anthropophilic black flies at 4 localities in Guatemala with different prevalence rates of onchocerciasis was assessed using human attractants and semimonthly catches over one year. Density of host-seeking was greatest at the locality with the highest incidence of onchocerciasis and very reduced at the 2 localities with low levels of human infection. The overall percentage of parous host-seeking at the 4 localities ranged from 41%–49%. Host-seeking activity appeared to be concentrated near streams containing immature stages, and few females dispersed as far as 3 km away. was the second most frequently captured species; however, at the locality with the highest prevalence of onchocerciasis, its host-seeking density was much less than that of . For , the overall percentage of parous females ranged from 28%–34% at the 4 localities. were consistently taken in much greater numbers in coffee cultivation areas than in housing areas. Host-seeking and also were captured.
