Oystershell Scale in No. Arizona above 6000’ Elevations
The oystershell scale is a common armored scale insect on a variety of plants in the higher elevations of northern Arizona.The scales damage the plant by inserting their hairlike mouthparts into thin bark regions of the tree and sucking the sap out. Heavy infestations can kill plants. Aspen, lilac, ash, willow, and maple are vulnerable because the thin bark offers a good feeding site. Management can be with mechanical, biological or chemical methods.
