Download The Literature of American Economic Entomology (Classic Reprint) Book in PDF, ePub and Kindle
Excerpt from The Literature of American Economic Entomology The literature of American economic entomology has become so extended that detailed indexes are an absolute necessity; otherwise many valuable records are lost, so far as the busy worker is concerned. The first general index published was that to Riley's nine Missouri reports, and in many respects it is a model publication. It is not only very detailed, but every insect is indexed by its specific as well as its. Generic name, something which the speaker is inclined to think of great importance. The many changes in nomenclature make it very difficult for a person to keep up with them, and the index which lists a species by its specific as well as generic name aids materially in this respect. This publication is perhaps open to one criticism, in its having separate indexes for plants and insects. This is to some extent a matter of taste, and yet the speaker is inclined to believe that the general index, including all references, is superior, since no question can arise as to which index is before the seeker for information. This is something which used to trouble my distinguished predecessor not a little and my hearers are probably aware that all the later indexes prepared under his direction have included every reference. The next general index to appear was that by Professor Forbes of the first twelve reports of the State entomologists of Illinois. This is. Prepared on very nearly the same lines as that to Riley's Missouri reports, and is also open to the criticism of having separate indexes for plants and insects. It is, however, admirably gotten up and has proven of great value to working entomologists, since it renders more accessible the vast amount of information recorded in these reports.

Excerpt from Journal of Economic Entomology, 1913, Vol. 6: Official Organ American Association of Economic Entomologists President W. D. Hunter: We will now listen to the report of the Committee on Nomenclature by Prof. Herbert Osborn. Mr. Herbert osborn: No list of insect names has been submitted to the committee during the year and, therefore, we have no list to re port to the Association. The committee feels that an improvement in the use of common names has resulted from its work. Several books and other publications that have appeared recently have used the names suggested in the lists. We have no further report to make at this time.

Download Injurious and Useful Insects Book in PDF, ePub and Kindle
Excerpt from Injurious and Useful Insects: An Introduction to the Study of Economic Entomology This little 'book has been written for beginners who are willing to take some pains to acquire a practical knowledge of insects, and are specially interested in the application of entomology to agriculture, horticulture, and forestry. A practical purpose is, in my Opinion, not a hindrance but a powerful motive to the acquisition Of scientific knowledge. If not too narrowly prosecuted, the practical purpose may be a means of distinguishing knowledge which is really useful from knowledge which is merely curious. I feel sure that it is much more likely to exercise a wholesome influence on natural history than collecting and naming, which have been far too exclusively attended to for many years past.

Download Insects of Economic Importance Outlines of Lectures in Economic Entomology (Classic Reprint) Book in PDF, ePub and Kindle
Excerpt from Insects of Economic Importance Outlines of Lectures in Economic Entomology Not all insects of economic importance are included in these outlines. To discuss them all, a book of many times the size of this would be needed. However, the principal pests of our main fruits, vegetables, cereals, farm animals, shade-trees, and of the household are discussed. A brief summary of the life habits of each, so far as they are known, is made, and the latest methods of control are outlined. In addition, a concise discussion of insecticides is given together with formulae and directions for making and applying them. Finally, references are given to the more important sources of information regarding the insects and their control. As far as possible, references are made to bulletins available to the general student and to those publications giving good illustrations of the insects, together with the most approved methods of control. It is neither possible nor desirable to give references to all the literature on any one insect pest but additional references to the later literature as it appears from time to time will be cited during the course.
