SYMPTOMS 
Yellow spots form on leaves caused by the feeding activity of the aphids.
Leaves will often become cupped or distorted. Feeding activity may also
cause reduced flowering. Often, honeydew (a sticky substance) will be
found on the tree and on plants growing below. Sooty mold, a black fungus
that grows on the honeydew may also be present.
DESCRIPTION
OF PEST 
The Crapemyrtle Aphid is very small (approximately 1/8 inch) and yellowish-green.
Their soft bodies are sparsely covered with dark, stout hairs. They
have long antennae which sweep over their back. They may or may not
have wings. Wings are transparent with translucent brown veins, and
extend beyond the abdomen.
LIFE
CYCLE
Crapemyrtle
Aphids survive the winter as eggs which have been laid in cracks and
crevices in twigs or under bud scales. The eggs hatch in the spring
where the aphids begin feeding on the succulent new growth. After about
10 days, this first generation of aphids, which are all female, begin
giving birth to live young at the rate of up to one every 30 minutes.
All of these offspring are also female and will begin bearing after
approximately 10 more days. Multiple generations occur through the growing
season in this same fashion until fall when male aphids will be produced
for mating to form the overwintering eggs.
MANAGEMENT

The following
varieties have shown to be somewhat resistant to the Crapemyrtle
aphid: `Acoma,' `Apalache,' `Biloxi,' 'Caddo,' `Choctaw,' 'Comanche,'
`Fantasy,' `Hopi,' `Lipan,' `Miami,' `Muskogee,' `Natchez,' `Osage,'
`Pecos,' `Sioux,', 'Tuscarora,' `Tuskegee,' `Wichita,' `Yuma,' `Tonto,'
and Zuni.'
CHEMICAL
There are many insecticides labeled for control of aphids. Insecticidal
soaps are an environmentally friendly option. The key with using
the soap sprays is that it has to contact the aphids when you
spray so thorough coverage is essential. Dormant oil sprays can
be used to help kill the overwintering eggs; again, thorough coverage
is essential for control. When using any pesticide, always read,
understand and follow the label directions.
BIOLOGICAL
Aphids are the favorite food of many beneficial insects. Lady
beetles and their larvae, green lace wing larvae, parasitic wasps,
and serphid fly larvae are excellent aphid predators. Learn to
identify these beneficial insects and limit your pesticide use
when they are present. |
