Download or read book Forest Insect Conditions in the Southeast During 1957 Classic Reprint written by William F. McCambridge and published by Forgotten Books. This book was released on 2018-09-10 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Forest Insect Conditions in the Southeast During 1957 Forest insect conditions continued to improve generally in the South east during 1957 (fig. 1) despite the fact that Ips beetles killed an estimated 10 million board-feet during one epidemic period and southern pine beetles destroyed over trees in the Southern Appalachian Mountains. Extremely cold weather in December killed a high percentage of southern pine beetle broods. The black turpentine beetle remained in outbreak status on the Hoffman Forest in eastern North Carolina. In Florida the beetle was much less active than in 1956. The elm spanworm (snow-white linden moth) was the only defoliator in outbreak status, although local infestations of sawflies, especially in Florida, were causing some concern. During 1957 a cooperative insect survey plan for Florida was developed and two semi-annual aerial surveys conducted. These surveys were under the direction of the Florida Forest Service, with the State Plant Board and U. S. Forest Service cooperating. During these surveys over ten million acres of forest land in northern Florida were covered by2.5-percent intensity. The summary of insect conditions presented in this report includes only those infestations which caused, or were capable of causing, serious economic losses. A few minor insects of special interest are also noted. This report is made up to a considerable extent from information submitted directly to this office by cooperators and from reports and information submitted by pest control foresters, especially from Virginia and North Carolina. The summary of formal cooperative reports is presented in table 1. While the number of reports received by this Station in 1957 is less than those submitted in 1956 insect conditions during the year were under much greater scrutiny. In Virginia, field reports from each district are summa rized monthly by the insect and disease specialist in the Division of Forestry. Copies of these reports are submitted to this office. In addition, the associate extension entomologist puts out a monthly economic insect report containing a section devoted to forest insects. A somewhat similar but less formal system exists in North Carolina, and this office is kept informed of all serious infesta tions by frequent written and verbal communication. The State of Florida israpidly developing an extensive reporting system and this year has developed an intensive aerial sampling survey for the detection of insect infestations and for an appraisal of insect losses.

This book was released on 2018-01-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Forest Insect and Disease Situation, Lake States, 1960 Insects and diseases play an important part in the reduction of our vast forest resource. Each year they cause large losses in timber growth and result in tree mortality. But that is not all: These agents attack the forest from seed to finished product. Stocking levels are lowered, growth is retarded, and trees are deformed, thus reducing both quality and quantity of forest products. The protection of our forests against these destructive agents is the responsibility of everyone concerned with the national economy. This report summarizes the information collected by many agencies and individuals on the forest insect and disease situation in the lake States during 1960. The most important aspects are presented briefly in the next few pages. For more detailed discussion see sections on The More Important Forest Insects (or Diseases).

Book excerpt: Excerpt from Forest Insect Conditions in Arizona and New Mexico, 1956 The 1956 aerial and ground surveys revealed an increase in insect-caused mortality in Arizona and New Mexico.

Epidemic infestations in 1956 totaled 1. 6 million acres. The extent and severity of pine bark beetle damage showed a marked increase. Douglas-fir beetle activity increased. Fir engraver beetle continued to deplete the white fir stand in the Sandia Moun tains of the Cibola National Forest. An unidentified needle miner became epidemic on ponderosa pine. Defoliation of Douglas-fir, true fir, and Spruce by the spruce budworm declined. The Great Basin tent caterpillar outbreaks remained unchanged.
