INSECT PATHOGENIC BACTERIA ASSOCIATED WITH MILLIPEDE
Abstract
Millipedes, often overlooked in microbial ecology, may serve as reservoirs for entomopathogenic bacteria with potential for biocontrol of insect pests. This is due to their chitinous exoskeleton which provides an ideal condition for the growth of entomopathogens. This study explores the diversity and biocontrol efficacy of insect-pathogenic bacteria associated with millipedes collected from the environment. Using microbiological culturing and identification, bacterial isolates from the cadavers of millipedes were identified and tested against worker termites (Macrotermes bellicosus). Results revealed a rich microbial community, with several isolates out of which Pseudomonas aeruginosa demonstrated high pathogenicity against the target insect. These findings indicate that millipede-associated bacteria could serve as novel biocontrol agents, offering an eco-friendly alternative to chemical pesticides. The study underscores the potential of millipedes as vectors for entomopathogenic bacteria and their role in advancing sustainable pest management strategies.
