Abstract

The Desert Locust (Schistoseca gregaria - SGR1): SGR continued developing in the central outbreak region (COR) where increased numbers of swarms were reported in eastern Ethiopia and central Somalia and many migrated northeastern Ethiopia and reached Eritrea. Some swarms also reach southern Red Sea coast in Eritrea. Mature swarms, hatching and band formations were reported in northern the central region migrated to adjacent areas in Ethiopia and reached northern and northeastern Kenya. Numerous immature swarms persist in Ethiopia and Kenya. No additional swarms arrived in Kenya the last few days suggesting that the peak of allochthonous invasion in Kenya has declined. Hopper bands and adult groups were reported in winter breeding areas on the Red Sea coasts in Sudan and Eritrea and the southeastern coast of Egypt. Swarms moved from northern Yemen and continued breeding in southern Red Sea coasts of Saudi Arabia. Control operations treated 316,414 ha largely in COR during January, showing a slight decrease from December 2020 control (336,900 ha). In the western outbreak region (WOR), the situation remained calm and control was carried out on just 42 ha in Mauritania and Algeria. The eastern outbreak region (EOR) remained calm.
