2021 Ontario Cereal Leaf Beetle Survey

We are gathering cereal leaf beetle (CLB) data again this year to help validate growing degree day models generated by AAFC-Saskatchewan. If you are out scouting cereal fields this growing season and come across CLB, we want you to let us know where you are finding this pest, what stage and how many you are finding. To enter your field information, please complete the CLB survey at the following link: Cereal Leaf Beetle Survey. The survey can be accessed from your smartphone, tablet or you can enter the field location information at your desktop computer.

As part of the CLB survey, we would also like 15 to 30 CLB larvae per field collected in vials of alcohol (or hand sanitizer) to send to AAFC-Lethbridge. There, Dr. Haley Catton will dissect the larvae to search for the very important parasitoid wasp, Tetrastichus julius. So if you find larvae, please contact Tracey Baute (519-360-7817) to coordinate these collections.
