This book was released on 1974 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial application of mexacarbate and Bacillus thuringiensis Berliner was tested against pine butterfly, Neophasia menapia (F. and F.). These were applied to 40-acre plots on the Bitterroot National Forest and adjacent State and private lands during June 1973. Two concentrations of each material were tested; these were 0.15 and 0.30 pound per acre of mexacarbate, and 0.5 and 1.0 pound of B. thuringiensis per acre. Both concentrations of mexacarbate caused pine butterfly population reductions of near 97 percent and B. thuringiensis provided 73 percent reduction at the • 0.5 pound rate and 92 percent at the 1.0 pound rate. Natural decline of late instar larval population precluded an evaluation of differences in degree of defoliation between treated and untreated areas.

Available in PDF, EPUB and Kindle. Book excerpt: For hundreds of years, the massive ponderosa pine of the U.S. Southwest has left multitudes in awe. After spending nearly three decades researching among these trees, Sylvester Allred shares his wealth of experience in the southwestern ponderosa pine forests with the world in Ponderosa. Ponderosa is the first of its kind to provide an introduction to the natural and human histories of the ponderosa pine forests of the Southwest that is accessible to all who wish to enjoy the forests. The book offers knowledge on elemental aspects of the forests, such as the structure of the trees, as well as theoretical perspectives on issues such as climate change. Included are discussions of biogeography, ecology, and human and natural history, illustrated by over fifty color photographs throughout. Allred presents his observations as if he is recalling his thoughts over the course of a walk in a ponderosa pine forest. His imagery-saturated prose provides an informal and enjoyable approach to discovering the history and environment of the ponderosa pine. Using a concise, straightforward writing style, Allred invites readers to explore the forests with him. Ponderosa includes: More than 50 color photos Learn how to estimate the age of a tree See the reptiles, birds, and mammals that make their home in ponderosa pine forests Much more!
