Lowering the humidity of stored grains to reduce damage from mold is an example of which pest management method?

• A. Physical/environmental modification
• B. Chemical control
• C. Biological control
• D. Mechanical control

Answer: (A)

Lowering the humidity of stored grains to mitigate mold damage is a clear example of physical or environmental modification. This approach involves altering the environment in which pests thrive, thereby reducing their ability to cause harm. In this case, by decreasing humidity, the necessary conditions for mold growth are eliminated, thus protecting the grain from infestation.

This method is effective because it targets the underlying environmental factors that contribute to pest issues, offering a proactive strategy rather than reacting with chemical or physical interventions after problems arise. Maintaining optimal storage conditions is crucial in pest management, as it can significantly limit the presence of both mold and other pests that thrive in high humidity.
