What is the types of ecological backlash?

Ecological backlash

Ecological backlash involves the counter-responses of pest populations or other biotic factors in the environment that diminish the effectiveness of pest management tactics. Many of these counter responses result from heavy mortality burdens imposed by the pest management tactics. Other responses arise from disruption of ecological processes or changes in resource levels of the biotic community. Ecological backlash mainly manifests in the form of resistance, resurgence, and replacement- the three "R" s of pest management awareness.
