Abstract

A strain of Bacillus sphaericus isolated from coconut husk pits in Sri Lanka proved to be rapidly larvicidal to Culex quinquefasciatus, the local vector of Bancroftian filariasis at a dilution of 103 organisms per ml. A distinctive feature of this organism was that it contained a parasporal inclusion attached to the spore and was of a serotype hitherto unrecorded.
