Desert Locust Bulletin No. 546, Apr 2024
Hopper Bands Decline
In March, the Desert Locust outbreaks decreased along the Red Sea and Gulf of Aden coast in the Central Region. Egypt, Eritrea, Saudi Arabia, and Sudan had second-generation hoppers, groups, bands, and immature adult groups, but annual vegetation was drying up and control operations decreased by 50% since January. Biopesticides controlled a few small bands on the southeast coast of Yemen. During the forecast, locust populations are expected to decrease along the coasts of the Red Sea and Gulf of Aden. Adult groups in Saudi Arabia will move east towards the interior, while any from Egypt and Sudan will move west to the irrigated areas of the Nile River. Good rain fell in Saudi Arabia during March and is likely to continue there as well as in Yemen during parts of April and May. As a result, one generation of spring breeding will occur with laying, hatching, and hoppers starting in April. Limited breeding is expected due to above-normal rainfall in late April and early May in southeast Iran and southwest Pakistan. Heightened cyclone activity is anticipated in May and June for the Gulf of Aden and the Arabian Sea. No significant developments are likely in the Western Region
