The City of Red Deer Parks department has identified the Cottony Ash Psyllid in Red Deer. This invasive pest feeds on Black and Manchurian Ash trees, consuming the sap, causing curling of the leaves, and ultimately killing them.
The Cottony Ash Psyllid has recently been introduced into Alberta, where it has no natural enemies. Damage to ash trees in Red Deer was noted last year, and it is escalating as populations of the pest increase. Ash trees in our community are endangered by this pest. Cottony Ash Psyllid
