Abstract
Blood meal sources of Culex pipiens pallens collected in the field during the daytime were serologically identified by the Ouchterlony method. Mosquito collections were made at two stations in two areas 4km apart from each other in the suburbs of Kyoto in 1973 and 1974 by using a drop-net cage and sweeping. Blood removed from the engorged mosquito was tested against ten kinds of antisera. Eight different hosts identified were mammals to reptiles, i. e., bird, dog, cat, cow, pig, mouse, snake and human, showing that the blood meal sources of this mosquito were not restricted to a particular host, but covered a variety of animals. Feedings on birds and dogs made up the greater part of the total identified at the two stations, but the ratio of bird-feeding : dog-feeding differed between the stations suggesting that the host selectivity by this mosquito might vary depending on the availability of host animals.
