The crapemyrtle bark scale is an invasive insect pest that was first reported in the United States in 2004. The scale has since spread all across the USA. A group of entomologists, horticulturalists, and economists around the country have teamed together to tackle this pest.

Containerized Crapemyrtle Bark Scale Trial

Containerized Crapemyrtle Bark Scale Trial

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 ...

Gulf States Horticultural Expo – Crapemyrtle bark scale team

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 ...

$3.3 million grant to Texas A&M AgriLife Extension

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. See AgriLife Today press release for more information: http://isatexas.com/crape-myrtle-bark-scale-to-be-targeted-by-3-3-million-grant-to-texas-am-agrilife-extension/ ...
