Abstract:
Abstract In this study, we observed effects of various slash treatments on pine engraver colonization. Five slash treatments (slash-free, chipped, small piles, large piles, scattered) were replicated five times at each of two sites, one consisting mainly of ponderosa pine and the other predominantly lodgepole pine. No pine engravers were found in slash-free or chipped slash treatments at either site. At the ponderosa pine site, significantly more pine engraver attacks and galleries were found in the scattered slash treatment than in small and large pile treatments. A significantly greater number of invertebrate natural enemies were also found in the scattered slash treatment, where they were approximately six to nine times as abundant as in the small pile and large pile treatments, respectively. No pine engravers were observed colonizing slash in the lodgepole pine treatments where slash was in an advanced stage of drying. At both sites, the use of a feller buncher–delimber during harvest increased the rate of drying of slash, reducing its suitability for pine engraver colonization. West. J. Appl. For. 17(2):96–100.

Abstract:
The pine engraver, Ips pini (Say), is broadly distributed across North America (Lanier 1972; Wood 1982; Seybold et al. 1995) with a host range that includes most species of Pinus L., and in rare cases, species of Picea A. Dietrich (both Pinaceae), within its range (Swaine 1918; Bright 1976; Wood 1982; Furniss and Carolin 1992). Ips pini has been recorded from Pinus banksiana Lamb., Pinus resinosa Ait., and Pinus strobus L. (eastern North America), and from three of four subspecies of Pinus contorta Dougl. ex Loudon [P. c. contorta, P. c. latifolia (Engelm.) Critch., and P. c. murrayana (Balf.) Critch.], Pinus coulteri D. Don, Pinus jeffreyi Balf., Pinus ponderosa Dougl. ex P. and C. Laws., and Pinus flexilis James (western North America) (Furniss and Carolin 1992; Seybold et al. 1995). Hopping (1964) reported I. pini on Picea rubens Sarg., Picea glauca (Moench) Voss, and Picea engelmannii Parry ex Engelm. The adult insect is intermediate in length relative to most Ips spp., ranging from 3.3 to 4.5 mm (Hopping 1964; Bright 1976; Wood 1982; USDA Forest Service 1985).

Abstract:
Isolations of Hymenomycetes on a preferential medium were attempted from preflight pine engraver beetles, Ips pini, and the following in-flight bark beetles: pine engraver beetle, I. pini; western pine beetle, Dendroctonus brevicomis; mountain pine beetle, Dendroctonus ponderosae; and red turpentine beetle, Dendroctonus valens. Thirty pine engraver beetles removed from ponderosa pine slash (preflight) yielded no hymenomycete. However, Hymenomycetes were isolated from 50 of 114 beetles (all species) trapped in flight; Fomitopsis pinicola from 44, and other unidentified suspected Hymenomycetes, from 6. Cryptoporus volvatus was not isolated from any of the in-flight beetles. Since most of these isolates were without clamps (monokaryotic), the beetles may acquire basidiospores after emergence from beetle galleries in coniferous trees as hypothesized previously for the Douglas-fir beetle, Dendroctonus pseudotsugae. The isolation of F. pinicola from all species of in-flight bark beetles indicates that these beetles may be important in the dissemination of this hymenomycete.

Abstract:
The responses of pine engravers, Ipspini (Say), in British Columbia to ipsdienol-baited traps containing low, medium, and high dose rates of the antiaggregants verbenone and ipsenol, released from impregnated polyethylene and polypropylene beads, respectively, remained significantly lower than responses to ipsdienol-baited control traps throughout the spring. During the summer, the responses remained low only in traps containing medium and high dose rates of impregnated beads. Antiaggregant treatment densities of 100 and 400 bubble cap release points per hectare reduced the numbers of pine engravers caught in ipsdienol-baited, multiple-funnel traps by 66.1 and 76.8%, respectively. In 50 × 50 m thinning-simulation plots treated with a broadcast distribution of antiaggregant-impregnated beads in 1990, 32.9% of the felled lodgepole pines, Pinuscontorta Dougl., were attacked; in untreated control plots, 53.1% were attacked. The mean attack density per square metre of available bark surface in the treated plots (1.3) was significantly lower than that in the untreated plots (1.9); however, where attack occurred there was no difference (8.8 and 9.4 attacks/m2, respectively). In a 1991 experiment, verbenone- and ipsenol-impregnated beads were applied to 15 × 15 m thinning-simulation plots at initial release rates of 2.5 mg of verbenone and 0.05 mg of ipsenol per square metre of ground surface per day, and at double these rates. For three treatments, low and high rates 3 weeks prior to the first attack by I. pini and a high rate 2 weeks prior to attack, the mean attacks per square metre of available bark surface per week were reduced by 77.1, 82.9, and 97.1%, respectively, compared with attacks on felled pines in untreated control plots. The results of these experiments suggest that a timely application of broadcast antiaggregants would prevent the development of an outbreak population of I. pini.

Abstract:
The pine engraver (PE), Ipspini (Say), often coexists with the mountain pine beetle (MPB), Dendroctonusponderosae Hopk., in lodgepole pine, Pinuscontorta var. latifolia Engelm. The PE colonizes the upper bole, while the MPB infests the lower bole. We investigated the hypothesis that interspecific interactions between the PE and the MPB within trees can adversely affect MPB progeny production or survival. In lodgepole pine bark attacked by both species, PE and MPB emergence holes had a strong negative interrelationship, suggesting that high numbers of one species resulted in lower numbers of the other. In the laboratory, attacks by PEs on lodgepole pine logs resulted in significantly decreased numbers of MPB progeny, particularly when MPBs and PEs were allowed to attack logs simultaneously. Reductions in MPB progeny were 92.8 and 96.2% when the ratios of attacking beetles were 100 PE: 50 MPB per square metre and 200 PE: 50 MPB per square metre, respectively, compared with that in control logs with 50 MPB per square metre. In an August field experiment, pheromone-induced attack by the PE on trees just attacked by the MPB resulted in a 72.5% reduction in mean MPB progeny production compared with that in MPB-attacked control trees. Possible reasons for the reduced success of MPB when it and the PE coinhabit the same host may be exploitation competition, interference competition, or introduction of fungal competitors deleterious to the MPB. Induced infestation by PEs of MPB-infested trees may have the potential to reduce or control MPB populations.

Abstract:
Abstract A 500-ac mixed-conifer forest near Cache Mountain in central Oregon was examined in 1979, 1992, 2002, 2004, and 2005 to document causes of forest health decline and subsequent wildfire damage. The site is dominated by grand fir (Abies grandis) and ponderosa pine (Pinus ponderosa), with some lodgepole pine (Pinus contorta) and subalpine fir (Abies lasiocarpa). Part of the area was clearcut or shelterwood harvested from 1983 to 1985. Between 1979 and 1992, grand fir increased substantially, whereas ponderosa pine decreased in stems and basal area/ac in the unharvested areas. From 1979 to 2002, grand fir experienced severe mortality that was caused primarily by the root pathogen, Armillaria ostoyae, and the fir engraver (Scolytus ventralis). In 2003, a wildfire burned all of the study area, and by 2004, most of the grand fir, subalpine fir, and lodgepole pine was killed. The least amount of mortality from fire occurred in the larger-diameter ponderosa pine. Two years after the 2003 fire, some of the grand firs with bole or crown scorch that were alive in 2004 were killed by fir engravers by 2005. For ponderosa pines, only a few trees with bole or crown scorch that were alive in 2004 were killed by bark beetles, mostly mountain pine beetle (Dendroctonus ponderosae) and red turpentine beetle (Dendroctonus valens), by 2005. This case study has relevance to current interpretations of forest health in similar mixed-conifer forests, the major causes of forest health decline, and the role of fire in forest health.

Abstract:
The capture of pine engravers, Ipspini (Say), in ipdienol-baited, multiple-funnel traps in British Columbia was significantly reduced when devices releasing ipsenol or verbenone were placed in the traps. These results suggest that ipsenol and verbenone are synomones released by Ipslatidens (LeC.) and the mountain pine beetle, Dendroctonusponderosae Hopk., respectively. When verbenone and ipsenol were released together from five stations 2 m apart on felled trees, at 50 and 1.5 mg per day per tree, respectively, there was a 66.7% reduction in the number of logs attacked and a 98.8% reduction in attack density. The same treatment caused a 74.1% reduction in attack density on standing trees surrounded by a 4 × 4 grid of 16 release devices at 5- m centres. The antiaggregant composition of verbenone plus ipsenol has considerable operational potential for use in precommercial thinnings and in areas where standing pines are of high value; e.g., in rural subdivisions, shelterbelts, and recreational forests.

Pine engraver beetle refers to 11 species of insects (in the Ips genus) living in the inner bark of Arizona’s conifers that can cause rapid decline and tree death. Typically, the beetles are found at higher elevations (4200 feet to 9000 feet), but have recently been detected at about 2400 feet, in Tucson. The six-spined engraver (Ips calligraphus ponderosae) has been the only species detected, so far, in Tucson. This is the first time these native bark beetles have been found in non-native pines in the Sonoran Desert.

Abstract:
Augmentative release of biological control agents against pest insects is a management tool that has been largely ignored in forestry due to a lack of understanding and means of producing potential agents. I investigated the effects of Tomicobia tibialis Ashmead on the reproductive potential of adult Ips pini (Say) by comparing the reproductive indices of parasitized and healthy adult beetles maintained together in different combinations in pine logs. From these experiments I determined that the parasitoid most greatly impacts female beetle reproductive performance resulting in shorter gallery lengths and decreased offspring production before the female dies. Male beetle reproductive success depended on the females in his harem; however, the parasitized male cannot go on to subsequent infestations as a healthy male may. Thus the overall reduction in beetle reproduction resulting from parasitism can be substantial. Laboratory rearing methods for T. tibialis using pine logs were also established, and an attempt to rear these parasitoids from beetles held on artificial medium was made. In sum, it is possible to rear this parasitoid and the impact on its host beetle is better understood. I feel further investigation into augmentation using T. tibialis against I. pini is warranted.

Full text
Abstract:
A compact micro pulsating heat pipe was developed and tested to investigate thermal performance. Micro Flat Plate Pulsating Heat Pipe (FP-PHP) was fabricated using DRIE MEMS technique. A total of 10 parallel interconnected rectangular channels forming a meandering closed loop are engraved on the silicon wafer with a thickness of 1 mm. The top of the silicon wafer was covered by a transparent glass plate (#7740PyrexTM) with a thickness of 0.5 mm to allow visualization of the internal thermo-hydrodynamic behavior in the PHP. The overall FP-PHP has length of 50 mm, width of 15.5 mm, and thickness of 1.5 mm, respectively. The width and height of the engraved rectangular channel is 1 mm and 0.6 mm and the hydraulic diameter is 0.75 mm. The ethanol is used for working fluid. The results show that the FP-PHP without working fluid has thermal resistance of 17 °C/W and the FP-PHP with working fluid of filling ratio of 50% has thermal resistance of 4 °C/W. In other words, the FP-PHP has effective thermal conductivity of 650 W/mK which is about 1.6 times as much as of that of the Copper (keff = 400 W/mK). Therefore the developed FP-PHP can be used as compact high performance electronic cooling system.
