What can be a consequence of pesticide use on beneficial insects?

The consequence of pesticide use on beneficial insects is that it can lead to a decline in their populations. Pesticides are designed to target pests, but they often do not discriminate between beneficial insects and harmful ones. Many beneficial insects, such as pollinators and natural pest controllers, can be adversely affected by the same chemicals that are meant to control agricultural pests. This decline can disrupt the ecological balance and lead to problems like decreased pollination and increased pest populations, since there are fewer natural predators to keep them in check.

While some practices may aim to minimize pesticide impact, the inherent nature of many pesticides poses a significant risk to beneficial insects and their populations, making this answer the most accurate reflection of the impacts of pesticide use in forestry and agriculture.
