Cultural controls of IPM include which of the following?

• A. Conservation, augmentation, importation
• B. Barriers, traps, handpicking
• C. Pesticide application
• D. Biological introductions

Answer: (A)

Cultural controls in IPM are actions that change the environment to reduce pest pressure without using pesticides. Conserving natural enemies means keeping habitats and resources that beneficial insects need, so they can attack pests—this includes avoiding broad-spectrum sprays that kill them and providing nectar or pollen sources, shelter, or floral diversity to support their populations. Augmentation involves releasing additional beneficial organisms to bolster their numbers when pest pressure is high. Importation, or classical biological control, means introducing new natural enemies from other regions after careful risk assessment to target a pest that local enemies can’t control. Taken together, these practices aim to manage pests by shaping the environment and biological community to favor natural control rather than relying on chemicals. The other options describe mechanical methods (barriers, traps, handpicking) or chemical control, or general concepts that aren’t the same approach as cultural controls.
