Answer :
Final answer:
Integrated Pest Management (IPM) uses biological control, such as introducing predator species, and may employ targeted chemical pesticides as a last resort to manage pests while minimizing environmental impact. Hence the correct option would be option b.
Explanation:
Integrated Pest Management (IPM) uses a variety of methods to control pests while limiting damage to the environment. One key aspect of IPM is biological control, which includes introducing species that prey upon and destroy pest species. This is a method of using organisms to control pests. Biological control ensures cost-effective, long-term, area-wide control of invasive species, with minimal impact on non-target organisms. Additionally, IPM may sometimes use highly targeted chemical pesticides, such as pheromones, to disrupt pest mating or targeted application of pesticides in the lowest effective concentration when nonchemical methods are insufficient. However, the indiscriminate use of chemical pesticides is considered a last resort in IPM strategies.
