Trap Plants as a Tool Against Thrips parvispinus in Tropicals

Sweet alyssum (Lobularia) as a trap plant for T. parvispinus.

Thrips parvispinus has become a serious pest of tropical ornamental crops in North American since 2020. Due to the severity of the damage, IPM strategies are needed to complement chemical control until an effective and economical biocontrol program can be developed for this pest.
