Sinopsis

Excerpt from Common Injurious Insects of Kansas

When we come to consider remedies, it is evident at once that remedies whose effectiveness consists in the fact that the foliage which is eaten by the insects is poisoned by being covered With' a coating of some arsenical mixture cannot be used against sucking insects who get their food from the inside of the leaves. And it is evident that barriers around tree trunks, or around plats of ground, which might surely prevent the progress of the Wingless caterpillars and worms, would not at all prevent the winged adult forms (the moths, etc.) of the insects - which adult forms lay the eggs from which the caterpillars are hatched - from getting into the tree tops, or into the plats of ground.

Excerpt from Common Injurious Insects of Kansas

The fact that Kansas is annually sustaining a large financial loss because of the attacks of injurious insects on its cereal, garden and fruit crops, a considerable part of which loss is needlessly suffered, is excuse for this pamphlet. Only the commoner, or more important, insect pests working within the State are considered. Nor are all the important pests included; though, of cereal pests, I believe most, if not all, are included.

In compiling the information presented herewith, the writings of reputable economic entomologists, generally, have been consulted and relied on. Bruner of Nebraska, Comstock of New York, Forbes of Illinois, Lintner of New York, Osborn of Iowa, Riley of the United States Agricultural Department, Saunders of Canada, Smith of New Jersey, Weed of New Hampshire, and others, are such entomologists. The Kansas notes have been derived from the reports of the State Board of Agriculture and the State Horticultural Society; from the published notes of Prof. F. H. Snow, of the University of Kansas, Prof. E. A. Popenoe, of the State Agricultural College, and Mr. G. C. Brackett. secretary of the State Horticultural Society; and from the unpublished notes of the Department of Entomology in the University. For valuable suggestions constantly offered during the course of compilation, I am indebted to Chancellor F. H. Snow and Dr. S. W. Williston, of the University.
