Download or read book Remedial Treatment of Lodgepole Pine Infested with Mountain Pine Beetle written by Paul E. Tilden and published by . This book was released on 1985 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lindane is registered for remedial control of bark beetles; however, forestry uses are controversial and alternative chemicals are needed. Chlorpyrifos (Dursban 4E), carbaryl (Sevimol 4), and fenitrothion (Sumithion 8E) at 1, 2, and 4 pct active ingredient, and lindane at the registered dosage of 0.6 pct were sprayed on lodgepole pine (Pinus contorts Dougl. var. latvolia Engelm.) bolts infested with mountain pine beetles (Dendroclonus ponderosae Hopkins) in Colorado. Mean survival ratios (n=10) of the proportions of beetles emerging from treated bolts to the proportion emerging from control bolts indicated that chlorpyrifos and fenitrotkion at 2 and 4 pct were about as effective as lindane in reducing emergence.

Download or read book Mountain Pine Beetle Emergence from Lodgepole Pine at Different Elevations Near Fraser, CO written by and published by . This book was released on 2005 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetle emergence was studied at 8760 ft, 9200 ft, and 9900 ft near Fraser, CO. Beetles began emerging at 8760 ft between July 9 and July 14 while no beetles emerged at 9200 ft and only one beetle emerged at 9900 ft during the same period. Beetle emergence continued at relatively low but fluctuating rates for the next two to three weeks. Peak emergence occurred about August 5 at 8760 ft, about August 12 at 9200 ft, and from August 12 to 19 at 9900 ft. Beetle emergence was complete by September 3. Average numbers of beetles emerging ranged from 5 to 256/ft2 of bark per tree with the means for each elevation not significantly different. Attack densities averaged between 6 and 9/ft2 of bark for the three elevations. Population trend ratios were computed for each tree and ranged from 0.4 to 32.0. Trend ratios varied substantially among trees but were not significantly different among elevations due to the significant variation among trees. The emergence period and population trend ratios are discussed in relation to suppression/survey projects and a stand susceptibility system.
