   Blueberries
 Home>Crops & Livestock>Crops>Blueberries>

Blueberry producers in many southeastern states are increasing production at a rapid rate. This has been driven by increasing consumer demand for blueberries due to their anti-oxidant, anti-aging properties and superior nutritional quality.

Researchers and agents with the LSU AgCenter, Mississippi State University, Auburn University, the University of Georgia and North Carolina State University have joined to form the eXtension All About Blueberries Community of Practice (CoP). This CoP is using novel, diverse educational methods to help our Community of Interest (CoI) increase blueberry production efficiency and correspondingly increase consumption of blueberries in the southeastern United States.

The All About Blueberries CoI is broadly defined as producers (commercial and backyard), distributors, and consumers of blueberries (youth and adult).

Azalea Caterpillar
Azalea Caterpillar
The azalea caterpillar is found in Florida from July through October on azaleas. Often, the caterpillars completely defoliate much of the plant before they are detected. While the caterpillar appears hairy, it is harmless to humans and can be picked off the bushes by hand.
Adult Thrip
Thrips
Thrips are small, narrow insects with “fringe wings.” Adult thrips have two pairs (four) of wings that are “fringed” with hairs. Thrips are mostly plant pests.
Blueberry Stem Borer
Scarring and/or Tunneling of Blueberry Plant Stems by Insects
Information about how blueberry stem borers and thrips cause damage by scarring and/or tunneling through blueberry plant stems, as well as information on how to manage them.
Blueberry Stem Gall Wasp
Blueberry Stem Gall
The blueberry stem gall is caused by a small chalcid wasp, Hemadas nubilipennis, which belongs to the family Pteromalidae. In recent years, these galls have become a concern because they occasionally contaminate the finished blueberry product.

High populations of the blueberry mealy bug can lead to poor plant growth and decline.
Aphid
Yellowing of Blueberry Plant Leaves by Insects
Information about the yellowing of blueberry plant leaves by aphids and leafhoppers, as well as information on how to manage these insect pests.

Leafhoppers
These insects (family Cicadellidae) are small (under ¼ 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. Most are green or brown, but some are quite brightly marked with green and red. The young resemble the adults but are smaller and wingless. These insects do little damage by feeding on plants. They do some damage, however, when they make a slit in the stem in which to lay their eggs.

Yellownecked Caterpillars
Young larvae of yellownecked caterpillars skeletonize blueberry foliage. Adult yellownecked caterpillars are seldom seen because they are active at night.
Leafhopper on blueberry.
Drying of Blueberry Plant Leaves by Insects
Information about how blueberry tip borers and leafhoppers can damage blueberry plants by drying the leaves.
Blueberry flea beetle.
Defoliation of Blueberry Plant Leaves by Insects
Flea beetles and yellow-necked caterpillars are two insects that defoliate the leaves of blueberry plants. Read for information about how to determine if these insect pests are invading your blueberry plants and what steps to take to control them.
Grasshopper on blueberry.
Grasshoppers
Grasshoppers are generally elongated insects with narrow, leathery forewings; large, membranous flying wings; and chewing mouthparts.
Blueberry flea beetle
Chewing of Blueberry Plant Leaves by Insects
Information about insects that damage blueberry plants by chewing on the leaves, as well as information about how to manage these insects.
Blueberry Bud Mites are very small and cannot usually be seen with the naked eye.
Blueberry Bud Mite
Blueberry bud mites are microscopic and white, living on the inner bud scales of blueberries from fall to spring. The blueberry bud mite can be found in blueberry crops in the eastern United States from Canada to Florida and among blueberry plantings in the Midwest, including Michigan, Ohio and Indiana.
Aphid have soft pear-shaped bodies.
Aphids
Aphids can cause deformation, wilting and defoliation of new growth of blueberry plants. High infestations can reduce fruiting bud formation for the following year's crop. Aphids produce copious amounts of honeydew and can cause secondary pest outbreaks of sooty molds on foliage and fruit. Aphids also can transmit blueberry scorch virus.
Cranberry Weevil
Blueberry Blossom Weevil
There is typically one generation of the blueberry blossom weevil per year in blueberry fields. This pest is most common in eastern North America.

Blueberry Gall Midge
Blueberry gall midge occurs sporadically, but when present it can cause reductions of 20 percent to 80 percent flower buds/fruit.
Cranberry fruit worm on blueberry.
Cranberry Fruitworm
The cranberry fruitworm is one of the most serious pests of blueberries in the eastern United States. Some fields have suffered 50 percent to 75 percent losses of fruit. Infested berries may be harvested and packaged without detection, resulting in consumers finding larvae in packaged berries.
Stink bugs mating
Stink Bugs
The degree of damage by stink bugs depends, to some extent, on the developmental stage of the plant when it is injured by the bugs.
Frass (insect waste) on blueberries
Frass is insect debris (waste or poop). Two insects can be identified on blueberries by the frass they leave behind.
