Descriptions of larvae and biology of cyrtobagous coleoptera curculionidae agents for biological control of salvinia



Descriptions of larvae and biology of cyrtobagous coleoptera curculionidae agents for biological control of salvinia



Proceedings of the Entomological Society of Washington 88(2): 303-312



The larvae of Cyrtobagous singularis Hustache and C. salviniae Calder and Sands are described and figured. A key to the larvae of these and to the larvae of three other erirhinine weevils, Neochetina bruchi Hustache, N. eichhorniae Warner and Neohydronomus pulchellus Hustache, used for biological control of water weeds, is included. Differences are reported between the biology of C. singularis in Zimbabwe, southern Africa and C. salviniae in Queensland, Australia, where the species were introduced for biological control of the aquatic weed, Salvinia molesta Mitchell. Their potential as biological control agents is discussed.
