Abstract
Newdata on the feeding patterns of Haemagogus (Haemagogus) janthinomys Dyar from
different geographical regions of Brazil, by using the precipitin test as the bloodmeal-identifying tool,
are presented. The following antisera were used: bird, dog, human, rodent, cattle, horse, and opossum.
The origins of 287 bloodmeals were identiÞed, whereas 33 specimens were negative to the antiserums
tested. Among the reactive specimens, 174 (60.6%) fed on only one food source, of which 35.1%
originated from birds, 19.5% from rodents, 12.6% from humans, 10.3% from cattle, 10.3% from opossums,
7.5% from dogs, and 4.6% from horses. One hundred six (37.0%) mosquitoes fed on two sources, of
which the most common combinations were bird rodent (16.0%), bird human (10.4%), and horse
human (9.4%). Seven (2.4%) mosquitoes fed on three different hosts. Our results suggest that Hg.
janthinomys is more eclectic and opportunist than previously known in relation to its hosts and that
such patterns are probably highly adaptive to a temporally and spatially variable environment.
