Forwarding this Action Alert that was shared with the Mid-Atlantic
Invasive Plant Council by Marc Imlay, invasive plant expert and member
of the Board of Directors of the Maryland Native Plant Society.
Giant Salvinia has been reported in Virginia. If it becomes invasive,
use of weevil biocontrol has been approved:

Introducing a weevil. The salvinia weevil, Cyrtobagous salviniae, is a
tiny black beetle from Brazil that specializes on salvinia species.
The weevil has been used successfully to combat giant salvinia
infestations since as early as 1980 in Queensland, Australia. The
first weevils were brought to the United States 2001.
Request for additional support to researchers to find safe and
effective biological controls for these non-native invasive species.
Current ongoing research projects include Chinese Privet, Japanese
Stiltgrass, Common Reed, Hydrilla, Oxeye Daisy, Common Tansy, Field
Bindweed, Giant Reed, Giant Salvinia, Beefsteak Plant, Small Carpet
Grass, Russian Olive, Russian Thistle, Scotch Broom, Water Hyacinth,
