A means to fight locust invasions ecologically has just been developed in Senegal. The prototype of the “locust harvester” was presented on October 17th, 2020 in the capital Dakar during a virtual conference.

Senegalese researcher Sanoussy Diakité has just presented his new machine, called the "locust harvester". This invention helps farmers to fight against locusts by sucking in the insects in flight. The inventor talks about an ecological solution as opposed to chemicals.
