Methods to protect forests from pathogens and insects include using integrated pest management (IPM). Identify one method of IPM that is used to control pests.

a) Biological control
b) Genetic modification
c) Chemical spraying
d) Habitat destruction

Answer :

Final answer:

The correct answer is A) Biological control. Biological control is an Integrated Pest Management (IPM) method used to control pests by utilizing natural predators, parasites, or pathogens.

Explanation:

The correct answer is A) Biological control. One method of Integrated Pest Management (IPM) that is used to control pests is biological control. Biological control involves the use of natural predators, parasites, or pathogens to manage pest populations and is a key component of IPM strategies. This approach seeks to reduce reliance on synthetic chemical pesticides by enhancing the roles of these natural enemies of pests.

In an IPM program, various control tactics are combined and may include cultural, mechanical, biological, and chemical methods, applied in such a way to minimize adverse effects on beneficial organisms, humans, and the environment. Chemical control is used as a last resort within IPM, and when pesticides are necessary, they are selected and applied to minimize negative impacts. By setting thresholds, monitoring pest populations, and developing targeted action plans, IPM aims to keep pest numbers below economically damaging levels while promoting environmental stewardship and sustainability.
