EFFICACY OF SOME COMMON AQUARIUM FISHES AS BIOCONTROL AGENT OF PREADULT MOSQUITOES

Abstract


Predation experiment using Betta splendens, Pseudotropheus tropheops, Osphronemus gorami and Pterophyllum scalare   were conducted against IVth instar Anopheline larvae and pupae with varying prey and predator densities. Ranking of individual predatory efficacy showed the sequence: P. tropheops > B. splendens > O. gorami > P. scalare against larva/form and B. splendens > O. gorami > P. tropheops > P. scalare against pupal form of Anopheles stephensi during 24 hours experiment in laboratory condition. Predation under co-existence in interspecific and intraspecific combinations revealed the significance of predatory efficacy with reference to prey density and water volume (search area).
