Permits Approved for Weevil Release

The USDA Animal and Plant Health Inspection Service has authorized permits to release the weevil Bagous nodulosus in the continental United States to help control invasive flowering rush. Flowering rush is now naturalized in wetlands, lakes, ditches, and slow-moving rivers in 23 States and is reported to damage fishing, hunting, boating, and other recreational sectors. APHIS issued a Finding of No Significant Impact, so no environmental impact statement will be prepared.

Weevil Shown To Be Host-Specific

Host-specificity testing in the agency's analysis indicates Bagous nodulosus is unlikely to attack non-target species. APHIS notes adults are active from April onwards and larvae feed from April to September, and the final environmental assessment led to a Finding of No Significant Impact for field releases.
