A method of killing mosquito larvae and particularly the species
comprising Culex tritaeniorhynchus, Cx. pseudovishnui, Cx. (Cx) sp., Cx.
(Lutzia) sp. and Anopheles hyrcanus group which comprises in allowing
Chilodonella uncinata as a ciliated protozoa to be present in said host
larvae, allowing the ciliated protozoa to form a hole in the wall of the
larvae and to enter into the haemocoelomic cavity of the larvae and to
thereby allow the ciliate to feed on the host larvae and simultaneously
allowing the host larvae to grow and allow a multiplication of the
ciliate, and whereby the multiplied ciliates kill the host larvae.
