Abstract

The Desert Locust (Schistoseca gregaria - SGR1): In the Central Outbreak Region (COR) the SGR numbers continued progressively declining in Ethiopia and Kenya and Somalia due to intensive control operations and delays in the seasonal rains although swarms continued forming in the NE and NW parts of Somalia during March. Control operations treated 13,366 ha in Ethiopia, 1,184 ha in Kenya, and 12,396 ha in Somalia during this month. Hopper bands formed from remnant swarms in northeast Tanzania where control operations treated 236 ha (plus 1200 ha). In Sudan, control operations treated 7,487 ha and egg laying, hatching and band formations continued on the Red Sea coast. In Eritrea, the situation remained relatively calm and hoppers were treated on just 100 ha in the central coastal areas. Egg laying, hatching and band formations continued in the interior of Saudi Arabia and control operations treated 50,120 ha. A few mature swarms crossed over to Kuwait and southwestern Iran. Scattered adults were reported in Egypt and Yemen. Low numbers of solitary adults were reported in Algeria and Morocco in the western break region (WOR). The eastern outbreak region (EOR) remained calm and only a few mature swarms that arrived from Saudi Arabia reached southwestern part of Iran and controlled on 1,521 ha.
