“This is a great opportunity to get direct answers about the scale of crap myrtle, an exotic pest that affects our favorite crepe myrtle, from the country’s leading researchers,” said project manager Manmen Gu, Ph.D. Texas A&M AgriLife Extension Service ornamental gardener and professor Department of Horticultural Sciences y College of Agriculture and Life Sciences at Texas A&M University, Brian College Station.

Gu is the group’s lead researcher on the crapemirt scale, which has been recognized for its national influence through webinars, videos and publications on YouTube.

She said the timing of the event is approaching how people typically see large-scale populations erupt on their crap myrtle plants.

Educational videos, information

Gu invites participants to visit on the eve of the meeting. The site offers information, publications and videos.

She said the following Video with crap myrtle bark will be especially helpful in preparing for the event.

What is crap myrtle bark?

First discovered in the United States in Dallas in 2004, crap myrtle bark is a sucking insect that feeds on phloem, or plant sap. It secretes a sugar solution known as “honeydew”, similar to that secreted by aphids, whiteflies and other sucking insects.

When a plant is heavily infested, the insects produce enough honeydew to cover the leaves, stems and bark of the tree. This honeydew will then eventually turn black if it is inhabited by fungi called sooty mold.

Crepe myrtle is the most popular summer flowering tree in the United States Although rarely fatal to trees, sticky leaves and black trunks greatly reduce the attractive appearance of trees and reduce the price consumers pay for the tree.

Exotic crepe myrtle bark scales have now been found on a wide range of plant species, including American beauty, spirea and St. John’s wort.
