Download or read book Log Bioassay of Residual Effectiveness of Insecticides Against Bark Beetles written by Richard Harrison Smith and published by . This book was released on 1982 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual effectiveness of nine insecticides applied to bark was tested against western, mountain, and Jeffrey pine beetles. Ponderosa and Jeffrey pine trees were treated and logs cut from them 2 to 13 months later, and bioassayed with the three beetles. The insecticides were sprayed at the rate of 1 gal (3.8 l) per 40- or 80-ft2 (3.6 or 7.2 m2) bark surface at varying concentrations. Effectiveness of treatment was based on reduction in length of egg galleries 2 to 3 weeks after initiating bioassay. All chemicals were quite effective for 2 to 13 months, except for malathion and Imidan which were relatively ineffective, depending largely on concentration and application rate. On the basis of equivalent amounts of lindane, the ranking ofeffectiveness ofinsecticides tested was as follows: (a) on western pine beetle: decamethrin> permethrin> lindane> Reldan> Dursban Sumithion> Sevin; (b) on mountain pine beetle: decamethrin> permethrin> lindane> Dursban Reldan> Sevin> Sumithion; (c) on Jeffrey pine beetle: decamethrin> permethrin> lindane> Sevin. The residual effectiveness of lindane was about doubled by adding 2 percent molasses, and high pH of water reduced effectiveness of Sevin. Other application parameters had little effect.

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.
