The scientific community working in the field of insect pathology is experiencing an increasing academic and industrial interest in the discovery and development of new bioinsecticides as environmentally friendly pest control tools to be integrated, in combination or rotation, with chemicals in pest management programmes. In this scientific context, market data report a 15% annual growth of the...

Bacteria active against dipteran larvae (mosquitoes and black flies) include a wide variety of Bacillus thuringiensis and B. sphaericus strains, as well as isolates of Brevibacillus laterosporus and Clostridium bifermentans. All display different spectra and levels of activity correlated with the nature of the toxins, mainly produced during the sporulation process. This paper describes the stru...

The objective of this work was to characterize reference bacteria strains, belonging the genus Bacillus and species correlated genera, by simplified morphological biochemical methods. characterization is based on aspects colonies, as well cytomorphology species, optical scanning microscopy. For characterization, sensitivity test antimicrobials disk-diffusion performed. Moreover, strains were ch...

Brevibacillus laterosporus (Bl) is a Gram-positive and spore-forming bacterium belonging to the brevis phylogenetic cluster. Globally, insect pathogenic strains of have been isolated, characterised, some activities patented. Two isolates, Bl 1821L 1951, exhibiting pathogenicity against diamondback moth mosquitoes, are under development as biopesticide in New Zealand. However, due suspected acti...
