What crops does the Variegated Grasshopper damage in Africa?

The Variegated Grasshopper is a significant agricultural pest in parts of Africa, where it can defoliate crops including cassava, maize, and various vegetables. Its ability to feed on toxic plants and sequester defensive chemicals makes it particularly difficult to control with conventional pesticides.
