Crapemyrtle bark scale (CMBS; Acanthococcus lagerstroemiae) is an exotic pest species that is causing aesthetic and economic damages to crapemyrtles and posing potential threats to other horticultural crops.

Feeding preference trials of CMBS were conducted on forty-nine plant species and cultivars in 2016 and 2019. The infestations of CMBS were confirmed on Malus domestica (apple), Chaenomeles speciosa (flowering quince), Diospyros rhombifolia (diamond-leaf persimmon), Heimia salicifolia (sinicuichi), Lagerstroemia ‘Spiced Plum’ (crapemyrtle), M. angustifolia (southern crabapple), and twelve out of thirty-five pomegranate cultivars.
