To maintain control over giant salvinia infestations, it is important to have local sources of good quality weevils that can be reared year-round, harvested and released in areas where they are needed.

This guide is intended to provide a basic understanding of salvinia weevil-rearing operations along with a practical set of guidelines that can be followed to construct and maintain weevil-rearing ponds in the southeastern United States. We hope this information may be applied to increase the number of local weevil nurseries and contribute toward greater control of giant salvinia. Pub 3551 pdf is 16 pages.
