Effect of encapsulation on the persistence of Bacillus thuringiensis var. israelensis, serotype H-14

Encapsulation of Bacillus thuringiensis var. israelensis Serotype H-14 (B.t.i.) in polyethylene strongly increased its persistence against second stage Aedes aegypti larvae in laboratory conditions simulating natural field conditions. B.t.i. encapsulated in palmitic acid was less persistent. The reasons for the enhanced efficacy of encapsulated B.t.i. are discussed.
