Emergency transboundary outbreak pest (ETOP) situation bulletin for September with a forecast through mid-November 2021.
The Desert Locust (Schistoseca gregaria - SGR1): In the central outbreak region (COR), locusts continued developing in eastern Ethiopia where more than 3,650 ha were treated against spring-bred immature swarms and hopper bands. There was also an indication that immature swarms began forming in the northeast (Afar and Amhara) and north (Tigray) regions where survey and control operations remained a challenge due to access. Swarms were reported in northern Somalia where 9,972 ha were controlled. Hopper bands formed in Djibouti. Swarms are forming in the interior of Yemen where control operations were limited to just 417 ha due to resistance from beekeepers. Small-scale breeding occurred in Sudan and 1,400 ha were treated against hoppers and adult groups. No locusts were reported in Eritrea or Oman and a few isolated adults were detected in southern Egypt. In the western outbreak region (WOR), local breeding formed scattered hoppers and adults in Mali and Chad. No locusts were reported in the eastern outbreak region (EOR) during this month.
