Book Description
Excerpt from The Journal of the Department of Agriculture of Porto Rico, Vol. 1 Formerly Entomologist of the Experiment Station of the Board of Commissioners of Agriculture of Porto Rico. From time to time various entomological workers have published references to the Coccidae of Porto Rico, but the list of twenty three Species collected on the island in 1899 by Mr. August Busck is, so far as known to the writer, the only attempt ever made to enumerate the Porto Rican scale-insects. This list appeared in 1900 in Bulletin No. 22, new series, of the Division of Entomology, United States Department of Agriculture, the determinations having been made by Messrs. T. Pergande, T. D. A. Cockerell, and C. L. Marlatt. In connection with this list it is stated that only one coccid, Asp-z! Diotas destructor, had been previously recorded from Porto Rico, this being in a reference in the Canadian Entomologist for 1895, the material having been taken by Mr. J. D. Hall in the city of San Juan. Some of the Coccidae of the island, especially those attacking citrus trees, are referred to somewhat fully in [the publications of the Porto Rico Agricultural Experiment Station. In these articles Messrs O. W. Barrett and W. V. Tower have treated the greatest number of species and given the most extended economic accounts.

Book Description
Excerpt from The Journal of the Department of Agriculture of Porto Rico, Vol. 2: April 1918 Since about 1913, the scab situation has been serious, the bulk of the fruit of some growers commonly being so badly disfigured as to be unsalable. Excepts as culls. Other diseases, of minor importance in themselves, have in the aggregate produced no inconsiderable losses. It is impossible to arrive with any degree of accuracy, at the total loss to be charged to diseases, so many separate items composing the whole, and this being in turn so intimately connected with the damage to be charged to insect pests and mechanical injuries. Then again, the loss from many diseases - for example, die back or bark rot. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
