What does physical/environmental modification typically involve?

• A. Changing pest genetics
• B. Altering habitat conditions to control pests
• C. Applying inherited plant traits
• D. Using traps and barriers

Answer: (B)

Physical or environmental modification typically involves altering habitat conditions to control pests. This approach focuses on changing the physical surroundings in which pests live, which can disrupt their life cycles or reduce their numbers. For instance, improving drainage to prevent standing water can reduce mosquito populations, or modifying plant placement can create barriers against specific pests. By making these environmental changes, the conditions no longer support pest proliferation, thus reducing the need for chemical interventions. This method emphasizes a preventative approach to pest management, promoting a healthier ecosystem while effectively managing pest populations.
