PHOTOS: Desert Locust warning

Swarms forming in the Sahel

Desert Locust swarms are present in Chad and should start forming shortly in Niger and Mali. The swarms are expected to move towards North-West Africa in the coming weeks. Although unusually favourable ecological conditions allowed two generations of breeding this summer, the rains have ended and vegetation is drying out. This will cause locusts to concentrate and group in those areas that are still green in the Sahel and form hopper bands and swarms during the remainder of October and in November. See pictures below taken in Niger in mid-October.
