Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Report Upon a Collection of Coccidae From Lower California In certain fields enough work has been done to give a reasonably clear conception of the nature of the life of the peninsula, but there remain some groups that have been practically untouched. Among these groups are the insects. Rather extensive entomological collections were made by Dr. Eisen in the southern portion of the peninsula, the region to which scientific writers have applied the name Cape Region, but even here practically no more than a beginning has been made. Throughout the remainder of the area almost no work at all has been done and con cerning certain groups there is no information whatsoever. From all this great area, as far as I am able to determine, not a single species of the Coccidae or scale insects has heretofore been recorded, although the richness of the ora is in itself evidence that this group Should be well represented. A few species have been taken from Carmen Island in the Gulf of California, but none from the peninsula itself. The present writer has long been keenly aware of the possibilities of extending our knowledge of these insects by explorations within this region. With the financial support of the california-academy of Sciences, the Department of Entomology of Stanford University and the United States Bureau of Entomology, it became possible to spend some time during the summer of 1919 in the southern portion of the peninsula for the purpose, in part, especially of collecting these insects. It is upon the results of this work that the present paper is based. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Papers on Coccidæ Or Scale Insects written by C. L. Marlatt and published by Forgotten Books. This book was released on 2017-11-11 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Papers on Coccid or Scale Insects: The National Collection of Coccid ; Issued April 23, 1908 Doctor Howard, while assisting Professor Comstock in the study of Cocciclae, took up particularly the subject of the chalcidid para sites of these insects, and presented as Part III of Professor Com stock's report a paper entitled Report on the Parasites of the Coccidae in the Collection of this Department. This was the begin ning of Doctor Howard's work on chalcidid parasites and led to his becoming the world's authority on the subject. How little was known of these parasites previous to the publication of this paper is shown by the fact. That, with four or five exceptions, the species described and figured were new to science. Professor Comstock retired from the position of Entomologist in 1881, but published in Professor Riley's Report for that vear a short illustrated article on Lac Insects, describing three new species. He also gave a brief article on methods of controlling scale insects. A much more important article on remedies for scale insects of the orange, by Mr. H. G. Hubbard, is published in the same report. In this paper some very good work is recorded and some of the more important modern methods of control are given first exploitation.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Papers on Coccidae or Scale Insects: The National Collection of Coccidae Mr. H. G. Hubbard, who has already been referred to as having published an important paper on remedies for Coccidae in the Annual Report of the Department for continued his investigation of orange insects and the means of controlling them, at Crescent City, Fla, as an agent of the Department of Agriculture, and published in 1885 his excellent report entitled Insects Affecting the Orange. This represented nearly four years' study and experiment, and dealt very largely with the common scale enemies of the orange. Mr. Hub bard's interest in scale insects, aroused in this study, continued, although he published nothing noteworthy afterwards on the subject. It was, however, his intention to bring out a new and thoroughly revised edition of his Orange. Insects, and to take up in connection with it a study of the classification of, Coccidae; but his untimely death prevented the accomplishment of this task.

Book Synopsis A Classification of the Scale Insect Genus Asterolecanium by : Louise May Russell
Download or read book A Classification of the Scale Insect Genus Asterolecanium written by Louise May Russell and published by . This book was released on 1941 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This revisionary study of the genus Asterolecanium has evolved from unsuccessful attempts to identify accurately an injurious member of the genus which evidently was introduced into the United States and from difficulty experienced in satisfying numerous requests for correct identifications of other economically important species. Consideration of literature and specimens in these efforts disclosed a degree of confusion regarding many of the especially destructive species which could be clarified only through a critical classificatory review of the kind here presented. In this publication the writer has attempted to provide descriptions and illustrations adequate for the identification of the intended species and a classification of these species based primarily on a critical study of their morphology.
Book Synopsis Marketing Peanuts and Peanut Products by : Harold Johnson Clay
Download or read book Marketing Peanuts and Peanut Products written by Harold Johnson Clay and published by . This book was released on 1941 with total page 1038 pages. Available in PDF, EPUB and Kindle. Book excerpt: The peanut, for over 20 years a leading crop in the Southern States, reaches the consumer in many widely different forms. Once grown exclusively for sale roasted in the shell and for feeding to hogs, peanuts are now more widely known in the salted form, and even larger quantities are marketed each year as peanut butter and peanut candy. In some years a considerable volume of peanuts has been crushed and the crude oil shipped to manufacturers of oleomargarine, compounds and vegetable shortenings, and salad oil. The course taken by the peanut in its journey from farm to the consumer, then, is necessarily a varied one, with many bypaths.
