About parasite infection by Ornithomya biloba of the Swallow (Hirundo rustica) in Wallonia.
Collette, P., Ponsen, R. & Tomasovic, G.
In 1988 and 1989 ectoparasite Diptera were detected on about 500 Swallow broods aged from 9 to 13 days. More than 700 Doptera were counted and 420 collected; all were Ornithomya biloba, a pupal hematophage ectoparasite. The pupae which had been laid at the end of the season, pass the winter in the nest and infect broods in the spring. Depending opn the year and the season between 20% and 60% of broods were contaminated. Certain broods were infected by dozens of Ornithomya but the majority of nests only contain three parasites, on average, i.e. less than one perjuvenile Swallow. In infected nests the distribution of the parasites can be very unequal.
