Barkbeetles of the Genus Dendroctonus Experiment Station, and in all of the principal forest regions of the country, in connection with the work of the Bureau of Entomology, have served to confirm these first impressions. In these investigations special efforts have been made to acquire information on the habits and seasonal history and other facts relat ing to the various species, and to collect an abundance of material for systematic study, all to form a basis for conclusions in regard to the principal enemies of American forests and practical methods for their control.

DOWNLOAD EBOOK →This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 edition. Excerpt: ...but slightly narrowed toward the head, and punctured, and elytra with coarse rugosities toward the base and declivity, the latter with long hairs. It attacks pine trees in Mexico, where a large amount of timber has died in certain localities, evidently owing to the work of this and the larger Mexican pine beetle. It excavates winding egg galleries (fig. 35) through the inner bark, the larval mines being concealed, like those of the western and southwestern pine beetles, beneath the inner surface of the bark. Very little appears to be known of the seasonal history and habits of this species, Fig. 35.--The smaller Mexican pine beetle (Dendroctonus mexicanm): Adult, greatly enlarged, and section of egg gallery, slightly enlarged. (Author's illustrations.) Fig. 36.--The smaller Mexican pine beetle: Distribution map. (Author's illustration.) but evidently they will be quite similar to those of the southwestern, southern, and Arizona pine beetles. It will therefore be subject to the same general treatment for its control, namely, the removal and burning of the infested bark during the principal period of larval development and during the inactive or overwintering periods, if such are found within its range. This species has not been recognized within the United States, but it is not improbable that it may be found in the pine forests of southern Arizona and New Mexico. The writer has identified thirty-six specimens received from Prof. A. L. Herrera and Dr. S. J. Bonansea, collected from pine in Amecameca, Michoacan, and Tacubaya, Mexico. BIBLIOGRAPHY.
