General Situation during September 2013
Forecast until mid-November 2013

The Desert Locust situation remained worrisome in Yemen where hopper and adult groups, bands and swarms formed in the interior during September. Only limited control operations could be carried out due to insecurity and beekeeping. Small swarms will form during the forecast period in there areas and move to the Red Sea and Gulf of Aden coasts where adults have already arrived and laid eggs that hatched and hoppers formed groups and bands. Early breeding has also occurred on the central Red Sea coast in Saudi Arabia. Continued breeding caused locust numbers to increase in the northern Sahel between Mauritania and Chad. Small groups could form in some areas as vegetation dries out. A further increase is expected in western Mauritania where breeding will continue during the forecast period.
