What is a common result of effective pest management?

The correct answer highlights a key outcome of effective pest management. A well-implemented pest management strategy focuses on controlling and minimizing pest populations to sustainable levels rather than simply eradicating them. This is achieved through a combination of methods such as cultural practices, biological controls, and targeted pesticide use, which aim to maintain an ecological balance.

By reducing pest populations, effective pest management helps protect crops, structures, and public health without causing undue harm to beneficial organisms or the environment. This outcome is essential for long-term pest control success and emphasizes the importance of integrated pest management (IPM) practices that prioritize the health of the ecosystem while managing pests.

Other options illustrate ineffective or undesirable outcomes related to pest control practices. For instance, constant pesticide application can lead to resistance and environmental pollution, while increased insect diversity is typically a positive effect of habitat health, not a direct goal of pest management. Higher pest reproduction rates directly contradict the objectives of effective pest management, as the aim is to control and reduce those rates.
