Abstract: | A selective medium containing a combination of starch, milk proteins, and streptomycin was used as a reliable indicator for the presence of Bacillus sphaericus in soil samples collected from a mosquito habitat where this pathogen was previously applied. The medium can also be used as an indicator substrate to retrieve B. sphaericus from infected mosquito larvae. Results show that B. sphaericus remains viable and infective 9 months after application as a larvacidal agent of mosquitoes in a roadside ditch. |
