Emergency Transboundary Outbreak Pest (ETOP) Situation Update for September with a Forecast through Mid-November, 2014
The Desert Locust (SGR1 ) situation remained calm in September in summer breeding areas in the western outbreak region. Only a few adults and hoppers were reported in Mauritania, Niger and Chad. A similar situation may be present in northern Mali where surveys were not possible.
Algeria, Libya, Morocco and Tunisia remained calm during this month.
In northeastern Ethiopia where breeding continued in August, survey and control operations are in progress treated hoppers and mature swarms in 134 ha in September. In Sudan, scattered mature adults and hoppers were detected and controlled on some 2,430 ha in northeast during this period. A similar situation was present in summer breeding areas in the western lowlands in Eritrea.
Mixed instar hoppers were detected northeast of Hodeidah near Al Qutay in Yemen on 11 September.
The situation on the coastal areas along the Red Sea and Gulf of Aden where unusually early and good rains were reported from July through September were not clear due to lack of surveys. No locusts were reported in the summer breeding areas in Oman, Saudi Arabia or other countries in the region during this month.
The SGR situation remained calm in the eastern outbreak region and only few scattered adults were reported along the Indo-Pakistan borders.
Forecast: As a result of good rains that fell across west and east Sahel over the past months, breeding will occur in Mauritania, Mali, Niger, Chad and elsewhere in the region and increase locust numbers during the forecast period.
In the central outbreak region, small swarms will likely form in northern Ethiopia and migrate to the winter breeding areas in eastern part of the country and some may reach northern Somalia during the forecast period. Small-scale breeding will continue in western lowlands in Eritrea, but significant developments are not expected in the coming month. Swarms will form in northern and central Sudan and move to the northeastern part of the country and some will reach southeastern Egypt. Small-scale breeding is likely on the coastal areas in Yemen and Saudi Arabia where good rains fell during previous months (CDLCM/Yemen, DLCO-EA, FAO-DLIS, LCC/Oman, PPD/Sudan).
