Crape myrtles are being routinely treated to manage crape myrtle bark scale. Honeydew produced on trees from CMBS increases visitation by hymenopterans and dipterans. Systemic neonicotinoids translocate into pollen placing flower visiting insects at risk. Pollen analyses and surveys of trees in urban and rural landscapes reveal which groups of flower visiting insect may be most at risk from use of systemic insecticides.
