How does biotechnology help in controlling agricultural pests?

Biotechnology plays a significant role in controlling agricultural pests through the development of genetically modified (GM) plants that are engineered to be resistant to specific pests. This approach involves incorporating genes into the plant's DNA that either produce compounds toxic to pests or enhance the plant's natural defense mechanisms. By conferring resistance, these genetically modified plants reduce the reliance on chemical pesticides, effectively minimizing pest damage while also decreasing potential environmental impacts associated with pesticide use.

The advantage of using GM plants over traditional chemical pesticides lies in their targeted nature. The genetic modifications can be precisely designed to address specific pests without adversely affecting non-target organisms or beneficial insects. This targeted pest control can lead to increased crop yields, reduced farming costs, and a more sustainable agricultural system.

In contrast, solely relying on chemical pesticides has its drawbacks, such as the potential development of resistant pest populations, negative effects on non-target species, and environmental contamination. Therefore, the development of pest-resistant GM plants represents a progressive strategy in pest control within agricultural biotechnology.
