"In Sudan, groups of gregarious late instar hoppers are forming in North Kordofan and hopper bands formed northwest of Khartoum in the Baiyuda Desert. Groups of hoppers and immature adults were also seen further east near Kassala. Control operations are in progress and have treated at least 500 ha so far. As vegetation dries out, more groups, bands and perhaps a few small swarms are expected to form and move to the winter breeding areas." (http://www.fao.org/ag/locusts/en/info/info/index.html)
