In Overton, Texas, we’re about done tying up crapemyrtles, getting them on drip irrigation, and starting pre-assessments. We have a total of 100 standard (Queen’s Lace) and 100 dwarf (Pocomoke) cultivars, all highly infested with crapemyrtle bark scale, for our research trial. Before deciding what insecticides and timing of applications we would try, we had to summarize some of our past results. All of our past work on crapemyrtle bark scale insecticide trials are available through Arthropod Management Tests (https://academic.oup.com/amt and search for “crapemyrtle bark scale”). If you’re feeling a bit intimidated by the papers in Arthropod Management Tests, I made a short video tutorial walking through some of the jargon used in insecticide efficacy work. The following table is based on data from our Overton Center: Table last update July 8, 2020. We’re going to be testing some of the products that were considered “inconclusive” in our past trials,…

General review of crapemyrtles and common pests, crapemyrtle bark scale life cycle, spread, population dynamics, insecticidal control, and naturally occurring predators.

The crapemyrtle bark scale team started 2019 off with an afternoon session at GSHE in Mobile, Alabama on January 30, 2019. Attendees included landscapers, growers, regulators and other researchers. Some of the topics covered included new crapemyrtle cultivars, common pests and pathogens of crapemyrtles, management of crapemyrtle bark scale in the landscape and nursery, and alternative plant hosts of crapemyrtle bark scale. The PDFs of the presentations can be downloaded from the Presentations page.

General review of crapemyrtle breeding, landscape use history, new crapemyrtle cultivars, other common insects and diseases of crapemyrtle bark scale, and an introduction to crapemyrtle bark scale.

How to prevent crapemyrtle bark scale, insecticidal control trials, non-target impacts on beneficial insects, naturally occurring predators, and currently confirmed alternative plant hosts in the landscape.

Dr. Mengmeng Gu and collaborators have recently been awarded a 4-year $3.3 M grant from the USDA to tackle the crapemyrtle bark scale. The research involved collaborators all across the USA. The project will determine the population cycles of crapemyrtle bark scale, best management practices, biological control options, and even insecticide residue testing.

Welcome to the crapemyrtle bark scale resource website. Here we will house information on research being conducted within the USA on the biology, population cycles, plant hosts, and management strategies as we learn about it. Subscribe to our RSS feed to get updates as they come along.
