Neochetina Species And Arthropod Communities In Water-Hyacinth Rafts In South Carolina, Benjamin Powell

All Theses

Arthropod communities inhabiting feral water-hyacinth rafts were surveyed monthly in South Carolina's Coastal Plain from March 2005 through February 2006. Special attention was given to the chevroned waterhyacinth weevil [Neochetina bruchi (Hustache)], the mottled waterhyacinth weevil [N. eichhorniae (Warner)] (both Coleoptera: Curculionidae), and the waterhyacinth moth [Niphograpta albiguttalis (Warren)] (Lepidoptera: Crambidae), which were imported into North America to control water-hyacinth. Communities of arthropods are compared among sites, flow regimes (lentic, lotic, and tidal), and months of the year. The arthropod communities in waterhyacinth rafts in South Carolina are more diverse than previously reported. Rafts in each of …
