Unusually good rains may give rise to widespread locust infestations in the Sahel

The Desert Locust situation is currently calm. So far, only isolated adults have been detected in the summer breeding areas of Mauritania, Niger, Chad and Sudan. As unusually good rains fell in August throughout the Sahel, reaching further north than normal, there is potential for widespread breeding to occur that could cause locust numbers to increase substantially. This may not become evident until the seasonal rains end and vegetation starts to dry out, usually in October. At that point, locusts could concentrate and form numerous groups in many areas that could lead to outbreaks between Mauritania and Sudan. Therefore, countries should remain extremely vigilant and undertake regular surveys in all areas during the next few months. Elsewhere, breeding is likely to continue in northeast Ethiopia where hopper bands formed in August and were treated. The situation in Yemen remains unclear in the absence of surveys to confirm reports of adults on the Red Sea coast and swarms in the southern highlands. In Southwest Asia, a premature withdrawal of the monsoon is expected to bring summer breeding to an early end along the Indo-Pakistan border.
