Which of the following is a common problem associated with the use of insecticides?

The development of pest resistance is a well-documented issue associated with the use of insecticides. When insecticides are applied to control pest populations, some individuals may possess natural resistance to the chemicals. These resistant pests survive and reproduce, leading to a population that is increasingly tolerant of the insecticide. Over time, this can require the use of stronger or more toxic chemicals to achieve the same level of control, leading to a cycle of escalating resistance.

The implications of pest resistance are significant for Integrated Pest Management (IPM) practices. It can result in higher costs for farmers, as they may need to invest in more potent insecticides or alternative pest control methods. Moreover, pest resistance can disrupt ecosystem balance, as natural pest predators may also be affected by widespread insecticide use, potentially leading to further pest outbreaks.

In contrast, the other options do not accurately reflect common problems associated with insecticide use. Improved soil fertility and increased agricultural diversity are generally considered benefits of sustainable farming practices rather than problems. While the use of insecticides may sometimes lead to reduced crop yield if not managed carefully, it is not as direct a consequence as the development of pest resistance. This crucial understanding underscores the need for careful monitoring and management of pest populations within an IPM framework
