The desert locust, Schistocerca gregaria, is now raging across East Africa, the Arabian Peninsula and the Indian-Pakistan border, causing serious damage to crops and serious food crisis. This locust affects almost 10% of the world's population and 20% of the earth’s surface and annual damage of more than 40 billion yen in West Africa alone. Currently, it is feared that the new coronavirus epidemic will greatly hinder support activities in affected countries. JIRCAS is utilizing its vast experience in research collaboration with overseas partners in order to understand the ecology of desert locust in the field and to develop a sustainable management and control system that promotes environmental conservation.
