Which of the following would be considered a regulated pest?

The selection of an invasive species that threatens local ecosystems as a regulated pest is based on the significant ecological, agricultural, and economic impacts these pests can have. Regulated pests are typically identified by their potential to spread, cause damage, or disrupt both local flora and fauna. Invasive species often outcompete native species, alter habitats, and introduce new diseases, which can result in loss of biodiversity and greater management costs.

Regulatory agencies prioritize such pests for monitoring and control to protect native species and maintain ecosystem integrity. Their regulation is critical because they can cause widespread harm that often extends beyond local boundaries, affecting agriculture, forestry, and even human health.

In contrast, common pests in gardens or native insect species may not necessarily pose substantial risks to ecosystems, and pests deemed not typically harmful are less likely to be classified as regulated since they do not significantly threaten other species or economic interests. This distinction emphasizes the importance of biological invasions in phytosanitary practices, highlighting why the invasive species is an appropriate choice for a regulated pest.
