Locusts may increase in Ethiopia, Saudi Arabia, and Oman
The Desert Locust situation continues to improve along both sides of the Red Sea due to control operations and drying conditions in Sudan, Eritrea, Saudi Arabia and Yemen.
During April, adult groups moved into the interior of Saudi Arabia where one generation of breeding is expected in May. Several swarms moved from northwest Somalia into eastern Ethiopia where, despite aerial and ground control operations, breeding is likely to occur and hopper bands could form this month. Smaller-scale breeding is in progress in northern Oman and southeast Iran, causing small hopper groups to form. Pre-monsoon rains fell along both sides of the Indo-Pakistan border where adults may appear and early breeding could occur in May.
Unusually dry conditions prevailed in spring breeding areas of Northwest Africa. Consequently, no significant developments are expected.
So far in May, there have been new reports of more hatching in northeast Oman near Ibri where hoppers are forming small groups. Hopper infestations persist in a few places on the northwest coast in Somalia. Control operations continue in eastern Ethiopia against swarms.
