Under phytosanitary regulations, what pests must be reported without delay?

The emphasis of phytosanitary regulations is to manage and mitigate the risk posed by pests that can significantly impact agricultural and environmental resources. Newly detected invasive species or outbreaks of regulated pests represent immediate threats that can cause extensive damage to crops, ecosystems, and even human health. Quick reporting allows for timely response actions, such as containment, eradication, or management strategies to prevent the further spread of these harmful pests.

In scenarios where invasive species or regulated pests are identified, swift action is vital to protect local agriculture and prevent larger-scale infestations that could be much more difficult and costly to manage later on. This urgency is not applicable to common garden pests, which are often not regulated in the same way, nor to pests already under control, as they do not present an immediate threat. While any pest observed in agricultural areas might warrant attention, it is primarily the newly identified threats that must be prioritized for immediate reporting to ensure effective phytosanitary measures.
