Abstract: The surveys conducted for biological control agents of Hydrilla verticillata span an 8-year period. A total of 573 quantitative collections of hydrilla were made from 60 sites in costal Queensland and northern New South Wales. An additional 15 quantitative collections of hydrilla were made at 10 sites at Sydney, Mount Isa, and Darwin. Over 100 nonquantitative samples were also taken to supplement the quantitative surveys. This extensive sampling in Australia has led to the introduction into the United States of two insect biocontrol agents for hydrilla and the potential for other agents. These surveys have also assisted in the introduction of a biocontrol weevil for waterlettuce. NOTE: This file is large. Allow your browser several minutes to download the file.
