Excerpt from The Economic Status of Insects: As a Class A very recent instance of an international importation of striking value is the sending of Norms cardinalis from this country to Portugal, where the white or fluted scale has been checked and in many orchards ex terminated in the course of a single year. This importation was made by the writer with the invaluable assistance of the Cali fornia State Board of Horticulture.

In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

Excerpt from Class Book of Economic Entomology: With Special Reference to the Economic Insects of the Northern United States and Canada Although several most excellent manuals on Economic Entomology have been published in recent years, there seems to be a need for a book providing the necessary information for the student in the class room, laboratory and field along the lines indicated above. This class-book, therefore, has been prepared to meet the needs of the class-room instructor, and his needs have in uenced the mode of presentation of the subject material. It does not presume to take the place of the invaluable and well-known works of Folsom, Comstock, Slingerland and Crosby, and others; but rather, it aims to present such material as will best help the student in acquiring a fair working knowl edge of the modern science of Economic Entomology.
