PATTERSON, JOHN ELLIOT. ... Life history of Recurvaria milleri: the lodgepole pine needle-miner, in the Yosemite National Park, California. By J. E. Patterson. Reprinted from Journal of Agricultural Research, Vol. XXI, No. 3 Washington, D. C., May 2, 1921. Published by authority of the Secretary of Agriculture, with the cooperation of the Association of Land-Grant Colleges [cover title]. Washington: Government Printing Office, 1921. 25.8x17.7 cm, pp. 127-142 [143] [144-146: blank], 2 plates with 6 illustrations on 1 inserted leaf, 4 figures (including 1 map), 4 tables, gray wrappers printed in black, stapled. First edition. John Elliot Patterson, a Department of Agriculture entomological ranger assigned to carry out a special study of the Lodgepole Pine Needle-Miner in 1917, conducted field studies and experiments in the infested areas of Yosemite National Park during the spring and summer of 1917, 1918 and 1919. Patterson concluded that the cost of any method to control the moth was not warranted by the "present value" of the lodgepole pine in the park and that the reproduction of more desirable species, the mountain hemlock and fir which were flourishing as a result of the destruction of mature lodgepole pine by needle-miner invasions and barkbeetle epidemics, should be encouraged. The report includes a brief "historical review" of the lodgepole pine insect infestations first reported in 1903. Issued as Contribution from Bureau of Entomology (K-94). A fine copy. (#165511).
