Agriculture, Okanogan and Wenatchee National Forests, 2008 OCLC Number: (OCoLC)369323706 Subject: Ponderosa pine. Excerpt: . . . Fire-killed ponderosa pines were being infested by red turpentine beetles within three weeks of tree death by fire ( Chart 4 ). Four study trees were determined to be infested by red turpentine beetles when they were selected on October 4, 2007. The presence of large pink globs of fresh pitch close to the ground was evidence of red turpentine beetle infestations. Red turpentine beetles can vector bluestain fungi on their bodies and inoculate trees, ultimately resulting in stained sapwood ( Figure 7 ). Figure 7: Red turpentine beetle gallery and bluestaining fungi brought in by adult beetles. There were almost no changes in the fire-killed pines and Douglas-firs from their examination on October 4, 2007 to the next observations of standing trees on April 9, 2008 and examination of logs and disks from cut trees on April 14 and 15, 2008. Six months passed between the first and second examinations. Temperatures were cold during the fall and winter months. Precipitation was primarily in the form of snow. Insects, being poikilothermous ( cold-blooded ), were not active for most of the time between the first and second examinations. Two Douglas-firs cut in April had wood borer larvae under the bark. It was not possible to determine if wood borer eggs or the larvae had overwintered in the trees or the infestations began in the spring. Only two of the 44 Douglas-fir logs examined in April had wood borers. 14 This item ships from La Vergne,TN.<
