Malumphy, C.P. 2005 Eulecanium excrescens (Ferris) (Hemiptera: Coccidae), an Asian pest of woody ornamentals and fruit trees, new to Britain.. British Journal of Entomology and Natural History 18(1): 45-49.

Notes: Eulecanium excrescens (Ferris) is reported causing serious damage to ornamental Wisteria plants in Greater London, England. This is the first record of this polyphagous Asian pest in Europe. In China, it is a pest of apple, pear and peach trees although in the USA it does not cause economic damage. The host range, biology, geographical distribution and economic importance of E. excrescens are reviewed. Coccophagus obscurus Westwood (Hymenoptera: Aphelinidae) is recorded parasitising the scale for the first time.
