How is biological control different from chemical control in managing vectors?

Biological control is fundamentally centered around the use of natural enemies of pests to manage vector populations, which distinguishes it from chemical control methods. This approach leverages organisms such as predators, parasitoids, or pathogens that naturally prey on or otherwise suppress pest populations. By introducing or enhancing these natural enemies within an ecosystem, biological control aims to establish a balanced environment where pest numbers are kept in check without relying on synthetic chemicals.

This method is beneficial as it often leads to sustainable pest management by minimizing environmental impact and reducing the potential for the development of resistance that frequently occurs with chemical pesticides. In contrast, chemical control typically involves synthetic pesticides to directly kill or repel pests, which may not address the underlying ecological balance and can lead to negative consequences such as chemical residues in the environment.

Thus, the emphasis on utilizing natural enemies to specifically target vectors is what makes biological control a unique and effective strategy in vector management.
