Invasive exotic insects are rapidly increasing and spreading in a short period of time, threatening the ecosystem. Now, we need technology to monitor the dispersal of exotic insects and to strengthen the ecosystem risk assessment. The United States, Europe, and other countries are fully equipped with a biological control system for threats to biodiversity through systematic investigation and database construction, but Korea is not. Risk assessment and development of a dispersal/change prediction model are essential to maintain a safe ecosystem from invasive exotic species. This research group is carrying out a study to minimize the ecological damage by developing a prediction model of dispersal/change for invading alien insect species, a risk assessment technology and a response manual for management. I would like to look into the current state of exotic insect invasion through this small group meeting, and look for directions to study in the future.
