摘要
The subterranean termite Odontotermes obesus is an important pest of the Indian subcontinent, causing extensive damage to major agricultural crops and forest plantation trees. Control of termites by strategies employing their parasites has limitations because they have evolved a complex social structure, immune responses, and adaptive behavior toward pathogen-infected individuals. Nonparasitic rhizobacteria that produce harmful metabolites might facilitate the biocontrol of termites. In the present investigation, three different species of hydrogen cyanide-producing rhizobacteria were tested for their potential to kill O. obesus. The three bacterial species were found to be effective in killing the termites under in vitro conditions.
