| Abstract | Introduction: This study evaluated whether different strains of Brevibacillus laterosporus could be used to control larvae
of the blowfl y Chrysomya megacephala, a pest that affects both human and animal health. Methods: Mortality rates were
recorded after 1-mL suspensions of sporulated cells of 14 different strains of B. laterosporus were added to 2.5g of premixed
diet consisting of rotting ground beef fed to fi rst instar larvae of C. megacephala. All bioassays were performed using 10
larvae per strain, with a minimum of three replicates for each bioassay. Larval mortality was recorded daily up to seven days.
Results: Strains Bon 707, IGM 16-92, and Shi 3 showed the highest toxicity toward the larvae producing 70.5%, 64.5%, and
51.6% of larval mortality, respectively, which was signifi cantly higher than that in the control group (p < 0.05). In contrast,
strains NRS 1642, NRS 661, NRS 590 BL 856, NRS 342, ATCC 6457, Bon 712, and NRS 1247 showed limited or no
pathogenic activity against the target larvae. Conclusions: Our preliminary data indicated that B. laterosporus could be used
to develop bioinsecticides against C. megacephala. | pt_BR |
