Bracon Cephi

Bracon Cephi is a natural enemy of the wheat stem sawfly

This is a natural enemy of the wheat stem sawfly – a pest that has a couple warm spots this year according to Scott Meers. The parasitoid is kind of timely given the cold snap these days. It has glycerol and can super-cool to very low temperatures. Farmers can conserve it by leaving stubble as tall as possible as the wasps over-winter in the stems in the lower third portion of the plant.

You can revew the 2017 Wheat Stem Sawfly Forecast  and watch the Alberta Insect Pest Monitoring Network for 2018 forecasts.
