They can cause serious damage to the crops of Sesamum indicum (Pedaliaceae) and to Calotropis gigantea and Calotropis procera (Apocynaceae). It can also attack sorghum crops (Sorghum bicolor), Eleusine coracana, Pennisetum americanum, Phaseolus mungo, Arachis hypogaea, Lycopersicum esculentum, tobacco, sunflowers etc.[5]
