SIMPSON, Ill. – Releasing insects into high tunnels filled with fresh produce may seem counterproductive, but that’s exactly what is being done through a research study with Extension Specialist and University of Illinois Specialty Crops Entomologist Kacie Athey. The project was highlighted at a recent twilight meeting at the Dixon Springs Agricultural Center.
Spider mites, aphids, and thrips are some of the most common pests that can attack high tunnel plants. For most growers, infestations are treated through insecticides or other chemical control methods. Through the study, predatory insects like lady beetles, Orius, or predatory mites are released into the high tunnels as biological controls. The beneficial insects act as natural enemies that feed upon harmful pests that infest high tunnels. Sticky traps are also placed throughout the high tunnel to capture and assess the insect communities within high tunnels. The study is made possible through an Extension Collaboration grant, and it is also being conducted at the Student Sustainable Student Farm near the University of Illinois campus in Urbana. The preliminary data will help determine if biological controls help to control the pests within high tunnel systems.
Over the course of the evening, Local Foods and Small Farms Educator Bronwyn Aly also shared information on a tomato fertility trial that is being conducted within the high tunnels. The twilight series continues throughout the summer, with the next meeting scheduled for July 12 at Baebler Educational Farm in Waterloo on no-till tomato and pepper production.
