Abstract

Colisa fasciata consumed significantly more Chironomus ramosus larvae as compared to Culex
quinquefasciatus larvae and pupae when those were offered separately. In paired experiment it consumed
significantly more C. ramosus larvae than C. quinquefasciatus larvae. When habitat was modified by
incorporating sand and gravels on the floor of the aquarium, C. fasciata consumed significantly more C.
quinquefasciatus larvae as compared to C. ramosus larvae. Chesson’s food preference index also confirmed
these findings. The larvicidal efficiency therefore not only depends on the availability of alternative prey but
also on the micro-habitat condition.
