Swarms appear in SW Saudi Arabia from Yemen Several immature swarms arrived on the Red Sea coast and Asir Mountains in southwest Saudi Arabia during the past week. These swarms are likely to have originated from adjacent coastal and highland areas in northern Yemen that cannot be accessed safely. Substantial control operations are in progress against early and mid-instar hopper groups and bands on the Red Sea coast in Saudi Arabia from Jizan to Al Wajh. In Yemen, scattered adults are present on the Red Sea and Gulf of Aden coasts that have not required control so far.
