Can patterned tapes significantly improve thrips catches?
You’ve likely noticed by now that thrips populations are especially high because of thehot, dry summer. Many growers are noticing their usual biocontrol programs can’t keep up, and further defenses are needed this year.
The use of mass trapping strategies may be the key to getting an edge over thrips. This post discusses the latest research on mass trapping of thrips in ornamentals, including patterned sticky tapes and the use of pheromones.
