Why is biodiversity considered important in Integrated Pest Management (IPM)?

Biodiversity is considered important in Integrated Pest Management (IPM) primarily because it supports ecosystem health. A diverse ecosystem is more resilient, meaning it can better withstand and recover from various stressors, including pest outbreaks. When multiple species coexist in an environment, they contribute to a balanced food web, which can help regulate pest populations naturally.

For instance, a variety of plants can attract beneficial insects that prey on or parasitize pest species, reducing the need for chemical interventions. Additionally, the presence of diverse microorganisms in the soil can enhance nutrient cycling and plant growth, further promoting healthy crops that are less susceptible to pests.

Overall, a rich biodiversity fosters a more stable and sustainable agricultural environment, which is a key principle in IPM. This contrasts with ideas like promoting pest population growth, increasing reliance on chemical pesticides, or simplifying farming practices, which do not align with the goals of IPM that focus on environmental balance and sustainable pest management.
