Mass-rearing Cyrtobagous salviniae for biological control of giant salvinia: field release implications. Julie G. Nachtrieb

摘要

Giant salvinia (Salvinia molesta Mitchell), a free-floating aquatic fern native to South America, is considered one of the world’s worst weeds (Harley and Mitchell 1981). Infestations across the globe typically form dense mats, which clog waterways and impact recreational activities, irrigation, drainage, flood mitigation, hydroelectric production, and mosquito control, alter water quality, and displace native vegetation (Tipping 2004). In the United States, infestations have been noted in Louisiana, Texas, Alabama, Arizona, California, Florida, Georgia, Hawaii, Virginia, Mississippi, South Carolina, and North Carolina (USGS 2005)..
