Excerpt from Papers on Coccidae or Scale Insects: The National Collection of Coccidae Mr. H. G. Hubbard, who has already been referred to as having published an important paper on remedies for Coccidae in the Annual Report of the Department for continued his investigation of orange insects and the means of controlling them, at Crescent City, Fla, as an agent of the Department of Agriculture, and published in 1885 his excellent report entitled Insects Affecting the Orange. This represented nearly four years' study and experiment, and dealt very largely with the common scale enemies of the orange. Mr. Hub bard's interest in scale insects, aroused in this study, continued, although he published nothing noteworthy afterwards on the subject. It was, however, his intention to bring out a new and thoroughly revised edition of his Orange. Insects, and to take up in connection with it a study of the classification of, Coccidae; but his untimely death prevented the accomplishment of this task.

Excerpt from Papers on Coccid or Scale Insects: The National Collection of Coccid ; Issued April 23, 1908 Doctor Howard, while assisting Professor Comstock in the study of Cocciclae, took up particularly the subject of the chalcidid para sites of these insects, and presented as Part III of Professor Com stock's report a paper entitled Report on the Parasites of the Coccidae in the Collection of this Department. This was the begin ning of Doctor Howard's work on chalcidid parasites and led to his becoming the world's authority on the subject. How little was known of these parasites previous to the publication of this paper is shown by the fact. That, with four or five exceptions, the species described and figured were new to science. Professor Comstock retired from the position of Entomologist in 1881, but published in Professor Riley's Report for that vear a short illustrated article on Lac Insects, describing three new species. He also gave a brief article on methods of controlling scale insects. A much more important article on remedies for scale insects of the orange, by Mr. H. G. Hubbard, is published in the same report. In this paper some very good work is recorded and some of the more important modern methods of control are given first exploitation.

Soft Scale Insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research. At the time, the available knowledge and data were either scattered among numerous articles or regional monographs or were in obsolete books. It is hoped that this volume will cover almost the entire spectrum of the knowledge on the soft scale insect family, Coccidae. This book comprises six chapters and begins by discussing the natural enemies of soft scale insects, such as pathogens like entomopathogenic fungi; predators like coccineilidae and other coleoptera; and parasitoids like encyrtidae. It then discusses issues of damage and control, including pest status of soft scale insects and coccid pests of important crops. This book will be of interest to entomologists, horticulturists, zoologists, biologists, and those involved in general agricultural research.

This book is dedicated to the scientists whose professional devotion and accomplish ments in research on scale insects of the area made the compilation of this book possible. This book has two primary objectives: (1) to enable interested workers, who are not specialists of scale insects, to recognize and indentify these to families, genera and species; and (2) to provide information on the life cycle, host-plant range, natural enemies, geographical distribution, economic importance for each known species from Central Europe, and to provide a bibliography on each taxa covered. Scale insects are important pests of fruit and nut trees, forest vegetation, woody ornamentals, greenhouse and indoor plants. World-wide losses and increased production costs attributed to scale insects are estimated to reach $5 billion annually. It is difficult to recognize them because of their microscopic size and hidden habits. Identification of pest species enables plant growers to check appropriate reference sources for biological information and to select control methods.
