The effects of endosulfan and deltamethrin, chemicals used to control Glossina morsitans Westwood (tsetse fly), were tested against Cyrtobagous salviniae Calder & Sands (Curculionidae), a biological control agent for the floating fern Salvinia molesta. The weevil was very susceptible to deltamethrin and less susceptible to endosulfan. The use of these chemicals for control of G. morsitans in Botswana, where the biological control agent is active, is discussed.
