Book excerpt: Excerpt from Insects Affecting Domestic Animals: An Account of the Species of Importance in North America; With Mention of Related Forms Occurring on Other Animals The relations which insects bear to the other branches of the animal kingdom are of no little complexity, and the complete statement of these relations would require a lengthy discussion of definitions. In the, present work it is intended to discuss particularly those insects which by direct attack upon domesticated animals render them selves um injurious element to the stock breeder, poultry raiser, and keeper of various animals for pleasure or profit. Naturally, reference must here and there be made to allied forms which may be of interest as affecting some related animals or as possible parasites of domestic animals in the future. Insects may affect domestic animals in a number of different ways; first, by occasional attack for the purpose of obtaining food; second, by occasional attacks which simply give irritation to the animal, as in the case of certain species of flies; third, by living as parasites during part of their existence, as in bots; fourth, by living as parasites throughout their lifetime, as with the lice; and, fifth, by living as mess mates or scavengers upon the bodies of the animals without deriving nutriment from them, as, probably, some species of bird lice. In general, the insects affecting animals are termed parasites, but evidently this term would not be appropriate for all the forms above mentioned. It is by no means easy to give a definition which Shall be properly exclusive. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
