Abstract

Carrageenan microcapsules of the mosquito pathogen Bacillus sphaericus 2362 were prepared and tested for larvicidal activity against Culex sp. larvae in the laboratory. The durability of the bacterium in response to pH change, temperature, UV irradiation and several chemicals that can simulate polluted water habitats, in carrageenan beads with different polymer concentrations (0.5-2.0% w/v) was investigated. The results show that, with the protection of larvicidal activity, increased sporal resistance against these effects was achieved as compared to the free bacterium.
