Feeding patterns of Anopheles dirus, the major vector of forest malaria in north east India.

ABSTRACT

The feeding behavior of Anopheles dirus, the forest breeding, major malaria vector in northeast India was studied. The analysis of blood meals collected from this mosquito revealed that the species was highly anthropophilic in nature, the anthropophilic index being 90.5. The results of bait collection on human and cattle bait also confirmed its biting preference for human hosts. The species was observed to land on human bait throughout the night, showing prominent biting time at 20.00-21.00, 23.00-24.00 and 02.00-03.00 hours during the study period.
