Tree Pest: Cottony Ash Psyllid aka Jumping Tree Lice

Another Ash insect that has moved into the Winnipeg area in the last several years is the Cotton Ash Psyllid (CAP). This tiny insect is similar to an aphid. It attacks Black and Manchurian Ash trees (not Green Ash) by sucking sap from the underside of leaves and at the same time injecting a toxin into the tree. This toxin can kill the tree quite quickly (1-2 years). There is no effective treatment for this pest. As a result, whole streets planted with Black ash have died within the City of Winnipeg. This pest is found in Winnipeg and in many rural areas of Manitoba. When attacked the leaves of the Ash tree start to curl, shrivel and turn brown, at one point in mid-summer a white cottony like substance spreads across the underside of the leaves. Since there is no effective treatment the only solution is tree removal. Parkland Tree Care Arborists can help you identify the pest and affected trees.
