Feeding patterns of Haemagogus janthinomys (Diptera: Culicidae) in different regions of Brazil.
Abstract: New data 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 identified, 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.

This study provides fresh insights into the feeding patterns of the Haemagogus janthinomys species of mosquito across various regions of Brazil. It reveals that the mosquito’s choice of host is quite varied and opportunistic, with diets centered around birds, rodents, humans, cattle, opossums, dogs, and horses.
Methodology
- The research involved studying the feeding patterns of Haemagogus janthinomys, a type of mosquito, in different parts of Brazil.
- The team identified the blood source of these mosquitoes using the precipitin test, which involves using specific antisera to initiate a reaction with the blood consumed by the mosquito.
- The antisera used in this study were derived from various potential hosts, including birds, dogs, humans, rodents, cattle, horses, and opossums.
Results
- The origins of 287 bloodmeals were identified out of 320 (287 identified, 33 were negative to all antiserums).
- 60.6% of the positive samples fed on only one source. The primary sources of blood meals were birds (35.1%), followed by rodents (19.5%), humans (12.6%), cattle and opossums (both 10.3%), dogs (7.5%), and horses (4.6%).
- 37% of the mosquitoes were found to have fed on two different sources, with the most common combinations being bird and rodent (16.0%), bird and human (10.4%), and horse and human (9.4%).
- A small fraction (2.4%) of mosquitoes were found to have fed on three different sources.
Conclusion
- Contrary to previous understanding, the study found the mosquito species to be more eclectic and opportunistic in terms of its feeding habits. This suggests a high level of adaptation to changing environments, both temporal and spatial.
- The wide range of hosts, especially including humans, may have implications in terms of disease transmission.
