Q:Are there other biological control agents for TSA?

A: Yes, other insect herbivores are being studied or are going through regulatory process required before the release.  These insects include two additional defoliating leaf beetles Gratiana graminea and Metriona elatior, and the flower bud weevil, Anthonomus tenebrosus Boheman.  Additionally, scientists at UF/IFAS have developed a plant virus which is very effective in controlling TSA, and is applied much like an herbicide.  This product has the trade name SolviNix™ and is currently registered for experimental use.  It is anticipated that SolviNix ™ will be commercially available in the near future.
