Grasshopper infestations are reported on millet and sorghum in the sahelian
zone, notably in Dilly, Fallou, Mourdiah and Sébété
areas where some replantings have been necessary. Caterpillars attacked
young sorghum in Kirané area. Groups of Desert Locust adults
appeared in June in the Adrar des Iforas and west of Tombouctou near Lac
Faguibine and Lac Fate, where conditions were favourable for breeding.
Nomads reported a large swarm in the Tilemsi Valley and in the Timetrine
area but control operation teams could find only low densities of adults
during further surveys. Low numbers of solitary adults are expected to
persist in some parts of the Adrar des Iforas, Timetrine and Tilemsi as
well as further west near Tombouctou. Others are likely to be present or
appear near Gourma and Nioro. These are likely to breed on a small scale
in those areas where conditions are favourable.
