Does it pass the smell test? In an effort to protect wheat from one of its most virulent pests, researchers are gauging the reactions of the tiny insect to the scent of thousands of varieties.
Over the last several years, dry conditions have led to lower wheat midge levels in Western Canada, but spring rains in 2020 appear to have sparked a potential outbreak in various regions of the Prairies. Details and confirmation of these nascent flare-ups await release of data from the annual wheat midge survey. In the meantime, greater attention to midge management may well be required in the run-up to the incoming crop year.
