Which option describes inundation as a biocontrol method?

• A. conservation or augmentation of native herbivores
• B. inundate: pathogens or insects introduced as predators
• C. classical/importation of host-specific organisms from plant's native ecosystem
• D. general feeders/non host-specific species

Answer: (B)

Inundative biocontrol means releasing large numbers of natural enemies into the pest habitat to achieve rapid suppression. This approach uses high-density releases of pathogens or predator organisms so the pest population is overwhelmed quickly, without relying on long-term establishment. The option describes exactly that idea: introducing pathogens or insects as predators in inundative quantities to control pests right away.

The other biocontrol strategies differ: conserving or augmenting native natural enemies focuses on supporting existing beneficials rather than mass releases; classical importation involves introducing host-specific enemies that establish over time and persist; and using generalist, non-host-specific species can lead to broader, less targeted effects and is not the same as inundative, high-density releases.
