Parts 1&2, written by Dr. Sarah Jandricic, covered why to trap and when , as well as ways to improve mass trapping by choosing the right colour and placement . This post covers my summer research project looking into the utility of thrips lures. What kinds of lures are there, and do they work on multiple thrips species? And are they worth the extra expense? This post helps answer these questions for 2 common pest thrips species – western flower thrips and onion thrips . Stay tuned for more work on lures for mass trapping Thrips parvispinus, another aspect of my research project. Inside This Post: Inside This Post: Different Types of Lures for Thrips Do Lures Work?
