Yellowing of blueberry plant leaves can be indicators of certain insect pests that may be attacking blueberry plants. Insects that cause yellowing of blueberry plant leaves include aphids and leafhoppers. Click on the links below to find information on how to detect and manage these insect pests.

Aphids generally are less than 1/8-inch long. The adults have pear shaped bodies and their color varies according to species. Common aphids are green, yellow or black. Damages caused by aphids include deformation, wilting and defoliation of new growth of blueberry plants, as well as causing the leaves to curl or crinkle and flower buds to become hardened.

Leafhoppers are small (under 1/4 inch), mobile insects often found on the stems or undersides of leaves, where they feed by piercing the surface of the plant and sucking plant juices. Damage they can cause includes tip burn or drying of leaves, transmitting curly top and aster yellows viruses to some vegetables and transmitting blueberry stunt mycoplasma.
