Question

Quizplus · Accepted Answer

Selecting local enemies with narrow specificity for the pest in question is best from an ecological perspective as it minimizes the risk of introducing non-native species that may become invasive and cause harm to the local ecosystem. Additionally, if the natural enemies have a narrow specificity, they will not harm non-target species, and their population will not be affected by the presence of other predators, thus helping to maintain a stable ecosystem.
