Book Description
Excerpt from A Classification of the Scale Insect Genus Asterolecanium Although species of Asterolecaniwm, have been found on at least 37 plant families ranging from the Gramineae to the Compositae, they are most numerous on the Gramineae, Palmae, and Fagaceae. The species occurring on bamboos, palms, and oaks are, so far as known, limited to their respective host groups, but others may be found on members of several plant families, and still others appear to have a marked preference for a single host family and rarely occur on other, unrelated, hosts. Some members of the genus seem to be restricted in their feeding to one part of a plant, such as the leaves, stems, or bark, while others live indiscriminately on leaves, stems, twigs, fruit, and trunk. Some species apparently never produce pits, while others cause pits in some plants but not in others; thus the habit seems partially dependent upon the susceptibility of the host to pit formation.

Book Description
This revisionary study of the genus Asterolecanium has evolved from unsuccessful attempts to identify accurately an injurious member of the genus which evidently was introduced into the United States and from difficulty experienced in satisfying numerous requests for correct identifications of other economically important species. Consideration of literature and specimens in these efforts disclosed a degree of confusion regarding many of the especially destructive species which could be clarified only through a critical classificatory review of the kind here presented. In this publication the writer has attempted to provide descriptions and illustrations adequate for the identification of the intended species and a classification of these species based primarily on a critical study of their morphology.
