Leafhoppers are insects of importance to highbush blueberry growers in North Carolina. Species in the genus Scaphytopius, namely the sharp-nosed (Scaphytopius acutus) and blueberry leafhopper (Scaphytopius magdalensis), can contribute to economic losses in blueberry production. While these leafhoppers cause very little harm to blueberry plants directly, they can transmit a destructive disease called “blueberry stunt” through their feeding. Blueberry stunt is a microorganism that inhabits the sapwood of blueberry plants and infects its host for life. It causes severe stunting, with infected plants achieving only half the size of healthy plants, and once infected, disposal of the plant is necessary to avoid further spread. Therefore, it is important to monitor, identify, and manage associated insects as soon as they are observed in the field.
Whiteflies (Hemiptera: Aleyrodidae) are small (< 0.12 inch) and highly diverse insects that feed on the underside of leaves of many food crops and ornamental plants. They are a large group, with 1,550+ described species. The whitefly species most commonly found on North Carolina blueberries is Tetraleurodes ursorum, also known as the bearberry whitefly. Little is known about the biology and economic impact of this pest, and this fact sheet includes a summary and some points on its management in blueberries.
