Swarms move into eastern Ethiopia
At least ten immature and mature swarms have been reported appearing in eastern Ethiopia from adjacent areas of northwest Somalia on 5-10 April. The swarms were initially seen in Awbere District north of Jijiga and later spread to eight districts in the Somali region. The swarms varied in size from one to 20 sq. km. and are highly mobile. Some of the adults have become mature and nearly ready to lay eggs. Aerial and ground control operations treated six swarms.
In adjacent areas of northwest Somalia, there has been a decline in swarm reports compared to the last week of March. On 10 April, an immature swarm passed over Boroma and, two days later, a swarm was seen on the outskirts of the town.
Survey and control operations are continuing in eastern Ethiopia while new surveys are expected to be underway shortly in northwest Somalia to confirm the latest developments.
The adults will mature and lay eggs in the coming weeks in those areas where rains have recently fallen in eastern Ethiopia. Hatching, which is expected about two weeks later, will probably cause hopper bands to form.
