This textbook was written for students beginning a study of entomology. The student, his interest in and approach to the subject, and the type of information most worth, while to him have been kept constantly in mind in the preparation of the text. Most students taking the subject may never have more than this one course. The most important question is “What subject matter should be given and how should it be presented? This text is the result of more than 30 years of teaching a course in general and applied entomology and represents the author’s thoughts and views on the subject.
The author has striven to write simply and clearly and has attempted to present the subject as logically as possible. The more approved phylogenetic arrangement of natural groups has not always been followed, but they have frequently been arranged for study on the more sensible basic of habitat and metamorphosis.
One most always keep in mind that entomology is he study of insect-their recognition, biology and control. Certainly the study of taxonomy and biology of insects is most important for the beginner. Next in importance are the applied phases of the science. It is our though that morphology and physiology should be limited to only a working knowledge in an elementary text.
The most effective teaching of economic entomology can be done along with taxonomic and biological studies, since, at this time. It is possible to tie control to the biology and the taxonomic group of the insect more satisfactorily. Most details of insect control are omitted because control measures vary so much in different parts of the country that one must depend largely on local recommendations. Also, much detailed information pertaining to dosages and applications of insecticides may be found on the manufacturer’s label. Naturally, no textbook will fit the needs of every instructor. Adequate material has been included to allow considerable latitude in the choice of subject matter.
The study of insects is a most fascinating science, and this book attempts at every opportunity to arouse interest among the students. Although many injurious insects have been discussed, it is certainly not the desire to create the impression that all are harmful. The more important beneficial insects are stressed in their proper places. Rather simple and incomplete keys are given to the more important groups, chiefly for the purpose of acquainting the students with their use. Certainly, the student in his first course in entomology will not progress far in insect taxonomy. A chapter is included on making insect collections to encourage students to make collections and continue their studies. A Glossary is included to aid with technical terms.
