What is a key requirement for the sustainability of biological control organisms in turf systems?

• A. They must be able to move to or be placed in contact with the target pest.
• B. They must persist from season to season.
• C. They must be able to tolerate site conditions.
• D. They must reproduce rapidly regardless of environment.

Answer: (B)

Sustainability of biological control in turf systems depends on the organism’s ability to persist from season to season. When a beneficial predator, parasite, or microbe can survive and maintain enough population across changing conditions, it can provide ongoing pest suppression without needing constant reintroductions. This persistence means the biocontrol agent is present and active when pests rebound, helping keep pest levels in check over time. Initial contact with the pest matters for starting control, but lasting impact comes from staying in the system year after year. Being able to tolerate site conditions is helpful for survival, yet by itself it doesn’t guarantee long-term populations. Reproducing rapidly regardless of environment ignores ecological limits and can lead to instability or failure if conditions don’t support such growth. So the key requirement for sustained biological control in turf is that the organism persists across seasons.
