Which of the following is a consequence of continued use of the same pesticide?

The choice regarding the development of pesticide resistance in pest populations is notable because it highlights a significant ecological and agricultural phenomenon. When a specific pesticide is applied repeatedly to control a pest, the pests that might have a natural resistance or those that acquire resistance mechanisms over time survive the application. This leads to a situation where the once-effective pesticide becomes less effective, as the surviving pests breed, resulting in a population that is increasingly resistant to that particular chemical compound.

This dynamic is concerning for pest management strategies, as it can lead to the need for higher doses of the pesticide or the introduction of new chemicals, which can escalate costs and potentially lead to environmental impacts. Sustainable pest management practices often recommend rotation of pesticides, using integrated pest management (IPM) strategies, and employing various control methods to mitigate this risk of resistance.

The other options relate to possible effects of pesticide use, but they do not accurately address the primary consequence of repeated application of the same pesticide. For instance, while one might hope that continuous use could enhance effectiveness or pest sensitivity, it often leads in the opposite direction, as resistant pests proliferate. Similarly, reduction in pesticide toxicity does not directly correlate with repeated use of the same product; instead, it can lead to environmental concerns and harm beneficial
