But how do you figure out if this invasive pest is in your facility in the first place? And, if so, what’s the best way to monitor their populations?
After working with this pest for the last 1-2 years, researchers like myself have figured out which monitoring methods are most effective. This can help you identify the problem early, begin a management plan, and monitor the efficacy of your controls.
Although the invasive pest Thrips parvispinus continues to threaten tropical ornamental crops, the good news is that the sky isn’t falling. Producing crops like mandevilla, schefflera and hoya is still possible, at least in a closed greenhouse setting.
Although developing a reliable biological control program for this pest is probably a few years off, a suite of pesticides is available in the U.S. and Canada to successfully manage T. parvispinus.
This post covers these pesticides, their relative efficacy and demonstrates outcomes when used in an 8 month on-farm trial in mandevilla.
Join us for a GrowON webinar tomorrow (Tuesday May 30th) on potential solutions for Thrips parvisipinus from “boots on the ground” folks. This includes technical reps, industry consultants, and extension specialists.
Webinars on Thrips parvispinus are coming fast and hard lately, as scientists and extension agents try to get you the very latest information on this serious pest of ornamentals and peppers.
Join us for a GrowON webinar next Tuesday on potential solutions for this pest from “boots on the ground” folks. This includes technical reps, industry consultants, an your friendly neighborhood extension specialist in Ontario.
Sorry for the short notice folks, but even sometimes I’m out of the loop! There are two upcoming webinars on Thrips parvispinus, the new invasive thrips that is a serious pest of tropical ornamentals and pepper crops.
The first is by the University of Florida Extension folks, and should be a great update on what’s happening at the source. That webinar is TOMORROW (May 4) at 10am-12pm ET, so hopefully you see this in time! Hopefully it will be recorded for those that miss it.
The next webinar is on May 10th, and is being put on jointly by the Horticultural Research Institute, AmericanHort, the Canadian Nursery & Landscape Association, and American Floral Endowment.

As Ontario sources much of its plant material from Florida, it’s a good idea to exercise caution, even on non-tropical plants. The known host range of this pest is evolving, and thrips have the potential to hitch-hike on less-preferred plant hosts and spread to more preferred hosts in your greenhouse.
Read on for information on the situation in Florida and what you can do to help protect your greenhouse from this pest.
The recent boom in tropical plant production over the past few years means growers are encountering different and more challenging pests in greenhouses. Please join me and Judy Colley (Biological Technical Rep for Plant Products) for an upcoming webinar with Michigan State University Extension, where we talk about how to manage the “usual suspects” on various tropicals, as well as some of the more unique problems!

Increases in global trade, along with decreased use of harsher broad-spectrum pesticides makes it easier for insect species to move around the world. Because of this, it is becoming more common to find unusual pests coming in on plant material. It’s important that we are prepared and know what to do when something like a new thrips species makes an appearance.
The tropical thrips species Thrips parvispinus has been popping up in various parts of the globe in recent years and was intercepted on plant material in two Ontario greenhouses in 2021/2022. Read on to learn what we know about this species and what you should do if you suspect you have them.
