What is the main strategy of biological control methods?

  1. Using chemicals to eradicate pests

  2. Encouraging natural predators of pests

  3. Genetic breeding of resistant crops

  4. Physical barriers to deter pests

The correct answer is: Encouraging natural predators of pests

Biological control methods aim to manage pests and diseases by promoting the natural ecosystem balance. Option A, using chemicals, is not a favorable method as it can harm other beneficial organisms, while option C, genetic breeding, can be expensive and is not always effective. Option D, physical barriers, can also be costly and labor-intensive. As such, the main strategy of biological control methods is to encourage the natural predators of pests, which helps to control the pest population without causing harm to other organisms or requiring excessive resources.
