What is a common non-chemical method for controlling insect pests?

Crop rotation is the process of changing the type of crops planted in a specific area from season to season. This technique disrupts the reproductive cycles of insect pests, making it difficult for them to thrive and spread. B is incorrect because heavy pesticide applications can harm beneficial insects and create resistance in pest populations. C is incorrect because introducing more predators can disrupt the natural balance of an ecosystem and may not effectively control all insect pests. D is incorrect because using treated seeds only protects the crops during the germination and seedling stages, leaving the plants vulnerable to insect pests once they mature. Overall, crop rotation is a safer and more sustainable method for controlling insect pests.
