What is a method used to prevent insects from developing resistance to pesticide products in bioengineered crops?

Rotating bioengineered crops with non-engineered ones is an effective method to prevent insects from developing resistance to pesticide products. This approach disrupts the life cycle of pests that may target specific bioengineered crops. When crops with different genetic makeups are grown in succession, it creates an environment where pests cannot adapt and develop resistance as quickly, since they are exposed to varied plant characteristics, including differences in the way plants interact with specific pesticides. This rotational strategy introduces a level of ecological variability that can maintain the effectiveness of pest control measures over time.

Incorporating organic fertilizers does not directly address pest resistance and typically focuses on improving soil health rather than managing pest populations effectively. Increasing pesticide dosage can lead to greater selection pressure on pests, potentially accelerating resistance development rather than preventing it. Using a single crop variety can simplify management practices, but it also creates a monotypic environment that can lead to rapid pest adaptation and resistance, as pests become accustomed to the particular traits of that single variety. Thus, rotating bioengineered crops with non-engineered ones stands out as a proactive strategy for pest resistance management.
