This post was written by Kendra van der Wier, Greenhouse Floriculture Summer Research Student for OMAFA.

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.

Effective Mass Trapping For Summer Thrips, Part 2: Colour, Placement and Duration

*Yellow or blue – that is the question. Photo by A. Summerfield.*

Part 1 last week covered WHY to trap and WHEN to it’s best to put up your cards. This post goes over trap colour and placement to optimize thrips catches while reducing effects on natural enemies.

Although I’ve talked about this in older posts, I’ve put this data in context of what we know now, in terms of the various thrips species that invade Niagara greenhouses. I’ll also be sharing some data on card duration.

If that isn’t exciting enough for you, next week’s Part 3 will discuss whether or not using lures is worth it to increase thrips catches.

Mass Trapping For Summer Thrips, Part 1: Why Trap and When to Start (Answer: This Week!)

Sometimes your thrips biocontrol program is working great. Other times, it seems to get completely overwhelmed. Thrips can get out of control in Summer, when fall crop production is ramping up. This is where mass trapping can really help.

This post will cover where thrips come from, which species we find on cards, and when the best time is to add mass trapping to your thrips IPM program.

And stay tuned for Part 2, which will cover ways to optimize your mass trapping!

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.

Mass trapping through traps, lures, or trap plants can be an effective strategy for thrips. We’ve already seen that mass trapping cards REALLY help with this pest (more on that, later). And, it seems that trap plants may also be an effective strategy when used properly in vegetative crops.

Read on for what we did and how to implement it on YOUR farm.
