Developing effective phytosanitary measures to prevent the introduction of invasive insect pests

This chapter aims to provide a definition of phytosanitary measures, why they are needed, how standards for phytosanitary measures developed through international cooperation and how they relate to international agreements. It aims to explain how policy decision making and the management of invasive insect pests using phytosanitary measures is supported by the structured framework of pest risk analysis which follows international standards. Outlines of some of the more commonly used phytosanitary measures used to manage pest risk are provided. Case studies are used to illustrate the impact of phytosanitary measures. The chapter closes by identifying some of the key challenges we face to inhibit the introduction and spread of invasive insect pests with the aim of stimulating future research.
