Book excerpt: Excerpt from Key to American Insect Galls This key to American insect galls is an outgrowth of earlier studies of the gall midges and was assembled primarily to facilitate the identification of the numerous galls submitted for name. It gives for the first time, for American forms, a comprehensive survey of the curious plant growths caused by insects and their near allies, the plant mites. With such a guide many amateurs will doubtless be encouraged to enter a charming and delightful field of study, one which may be followed with profit for the child at School as well as by the student of more mature years. The specialist will find herein references to the best accounts of the numerous species listed as well as a summary of American literature, while the many records of host relationships can not be ignored by the biologist and ecologist. The obvious concentration of many forms upon relatively few host plants, especially those with numerous closely allied Species, such as the willows, oaks and goldenrods, and the great diversity of both structure and food habits among gall midges, all suggest interesting lines of study. These relationships are brought out more clearly in a tabulation of the hosts and galls (see page where 1441 species are listed, 682 being gall midges and 445 gall wasps. The remainder of the plant deformations discussed in this work are produced by a few of the other two-winged ies or Diptera, four winged ies or Hymenoptera, beetles or Coleoptera, moths or Lepidoptera, and the true bugs or Hemiptera, especially the plant lice and the plant mites or Eriophyidae, the last being represented by 161 species. The deformations, though numerous, by no means exhaust the possibilities and in the estimation of Mr L. H. Weld, a student of the Cynipidae, nearly one-third, mostly inhabitants of inconspicuous galls, are still unknown. It should also be remembered that extensive regions are comparatively unexplored for insect galls of all kinds.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Insect Galls of Indiana For some time I have been working upon a monograph of the Insect Galls of North America. This monograph will be arranged with reference to the plants on which the galls are produced, and special attention will be given to the galls as pathological structures. I should very much appreciate specimens and data from differ ent parts of North America. Most specimens are best sent dry, and should be accompanied by name of host plant or sufficient material for determination. All material and data will be duly credited.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insect Galls, Vol. 2: Of Springfield, Massachusetts, and Vicinity Within galls may sometimes be found parasites or inquilines. The former, preyin'g directly upon the gall-maker, causes its death, but not until its growth is nearly or quite complete. The inquilines are merely guests within the gall, profiting by the food supply and by the protection. Aside from the collection of the galls of different localities, and the sub sequent summary Of their distribution, two very interesting questions suggest themselves for investigation. First, are these malformations the result Of chemical or Of mechanical action? Second, Of which Of the American gall-makers is it true that there is alternation of generations? The classification of gall-insects will undoubtedly be somewhat altered when this question is answered. Either line suggests a fascinating series Of observations and experiments for the one undertaking it. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from A Contribution to the Morphology and Biology of Insect Galls In some forms the effect Of the stimulation does not extend beyond the epidermis, on which the producers are located, but in other species it is transmitted throughout the mesophyll of the leaf. The abnormal activity of the epidermis is expressed in the curving and folding of the tissue as well as in the production by it of various forms Of trichomes. In general, when the effect of the stimulation extends to the mesophyll the distinction between the palisade and the spongy parenchyma is lost. In place of these tissues a compact mass of uniform cells is produced. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
