Book excerpt: Excerpt from Proceedings of the Eighteenth Annual Meeting of the Association of Economic Entomologists: Issued September 22, 1906 I am sometimes asked to recommend a volume containing accounts of all the insects. If the and more known species from North America were described and the life history of each recorded it would fill not less than 150 volumes; and I have been compelled to refer my friends to such imperfect single volumes as we have, ex plaining, in apology, that our entomological literature IS scattered at present in numerous serials and in volumes relating to special groups of insects, and that no single volume contains more than a small fraction of acquired entomological lore.

This book was released on 2018-08-13 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Proceedings of the Eleventh Annual Meeting of the Association of Economic Entomologists, 1899 Every now and then, however, 'we are brought face to face with a disturbed balance Of a more general nature, the most striking examples of which are in the new insect enemies which come from time to time, and which in new situations and under strange Surrounding conditions multiply excessively and assume an economic importance which for the moment obscures all older like troubles. So universally true is it that the newcomer will prove more destructive than the old familiar pests, that this is looked upon as a fixed principle, like the law Of gravity. A good illustration Of this is seen in the recent very valuable book by Mr. E. E. Green on the insects Of Ceylon. Referring to the insects occurring on that island, he takes the position that excessive damage by an insect is a proof of its foreign origin. He says' that all the troublesome insects of Ceylon are introduced Species, and that not a single undoubtedly native Species has attracted any notice as a pest. Out Of twenty-six Species Of Chionaspis, for example, occurring on the island, three only are injurious, and these are introduced species. In this country our experiences have been more varied, and we probably would not go to the same extreme, but the history of insect introductions and migrations here and elsewhere certainly indicates the truth of the general principle. A good deal of the effort in applied entomology in recent years has been directed at evils Of this sort, namely, to prevent the introduction of in sect enemies from foreign lands, and to quickly exterminate or con trol them where they have gained a foothold. In connection with this field Of work it seems to me that the proper appreciation of certain underlying principles affecting the behavior Of such introduced enemies will Show that we are exhibiting much more anxiety and alarm than the occasion warrants, and that we are making vain attempts to accomplish the impossible and prevent the inevitable. This belief has been impressed upon the writer by the history of the new injurious insects coming into prominence from time to time, and the patent failure Of our efforts at extermination or quarantine.
