AbstractThe pine shoot beetle, Tomicus piniperda (L.), is an exotic pest that is regulated by federal quarantines in the United States and Canada. Mark–release–recapture experiments were performed with infested logs coated with fluorescent powder to determine if overwintering beetles in logs would leave a mill yard if infested logs were transported to sawmills in uninfested areas. Overwintering T. piniperda adults were marked with powder as they emerged in spring. Dispersal studies were conducted in four simulated mill yards and five operational sawmills to determine whether T. piniperda would colonize only the log pile in which they overwintered, fly to nearby log piles, or disperse beyond the mill yard. Each simulated mill yard was composed of 36 uninfested red pine logs, Pinus resinosa Ait. (Pinaceae), and 12 α-pinene-baited funnel traps set up to 100 m from a central release pile of six uninfested red pine and nine infested logs of Scotch pine, Pinus sylvestris L. At the five operational sawmills, baited funnel traps were set up to 400 m outside of each mill yard. Overall, 482 T. piniperda galleries were found on the experimental logs recovered from the four simulated mill yards combined. Tomicus piniperda adults dispersed and attacked the most distant logs at 100 m from the release point in the simulated mill yards. Likewise, adults were captured in baited funnel traps at distances up to 230 m in simulated mill yards and 250 m around operational sawmills. Although numbers of recaptured T. piniperda were generally low, in all cases some adults dispersed outside the mill yards despite the presence of abundant suitable breeding material. Therefore, logs containing overwintering adults pose a risk of spreading T. piniperda if not processed prior to initiation of spring flight.

Pine Shoot Beetle

AbstractHost preference of the pine shoot beetle, Tomicus piniperda (L.), was investigated in two laboratory choice test studies using red pine (Pinus resinosa Ait.) (Pinaceae), jack pine (Pinus banksiana Lamb.), and Scotch pine (Pinus sylvestris L.). Host preference of parent adult beetles was evaluated using freshly cut, similarly sized logs in a wind tunnel. Parent beetles colonized Scotch pine logs significantly more often when given a choice of Scotch pine and either red pine or jack pine logs, but did not show a preference when presented with red pine and jack pine logs. Host preference of progeny adults was tested in a laboratory bioassay using current-year pine shoots. Shoot-feeding progeny adults initiated tunnels in jack pine shoots significantly more often than in Scotch pine and red pine shoots, and preferred Scotch pine over red pine shoots. Shoots with diameters of 0.4–0.5 cm were attacked most frequently, regardless of species. Results suggest that the two North American pines are suitable hosts, but T. piniperda may be most likely to colonize Scotch pine, a European species. Efforts to detect or monitor T. piniperda populations in the Great Lakes and northeastern regions should focus on areas with abundant Scotch pine brood material. Progeny that emerge from brood material, however, may be as likely to shoot-feed in jack pine as in Scotch pine.

Pine Shoot Beetle

Established populations of an exotic bark beetle, the larger pine shoot beetle [Tomicus piniperda (L.)], were first reported in Ohio in July 1992. Subsequent surveys through July 1994 have found T. piniperda in six states in the United States and in one Canadian Province in the Great Lakes region. One-meter-long trunk sections were cut from Scotch pine (Pinus sylvestris L.) trees felled from February through July 1993 in a forested site in southern Michigan, laid horizontally, allowed to undergo natural attack by bark beetles and associates, and later dissected. In southern Michigan in 1993, T. piniperda initiated spring flight in late March; the pine engraver [Ips pini (Say)], a native pine bark beetle, initiated spring flight about one month later in late April. Tomicus piniperda attacks (galleries) were found in logs cut during February through May. Attack densities of T. piniperda were highest in February-cut logs, and declined with subsequent felling dates. The highest T. piniperda attack density recorded for an entire log section was 263 attacks/m2 of bark area on one of the February-cut logs. Ips pini attack densities tended to increase with later felling dates. When I. pini attacked logs that had already been colonized by T. piniperda, I. pini galleries were mostly found on the upper log surface. When I. pini attacked logs with few or no T. piniperda, I. pini galleries were found on all log surfaces. By initiating spring flight several weeks before I. pini, T. piniperda is able to colonize much of the susceptible pine material and thereby may lower I. pini populations.

Pine Shoot Beetle

Tomicus piniperda (Linnaeus), a pine shoot beetle native to Europe, was first discovered in the United States in July 1992, in a Christmas tree plantation in Ohio. Since then, intensive surveying by the U.S. Department of Agriculture and state departments of agriculture has revealed its presence (as of 29 December 2003) in twelve northern states: Illinois, Indiana, Maine, Maryland, Michigan, New Hampshire, New York, Ohio, Pennsylvania, Vermont, West Virginia and Wisconsin (Anonymous 2004b). Because T. piniperda occurs about as far south in the Old World as the latitude of Florida, it is considered a potential threat to at least some of the pine species intensively cultivated in Florida. This document is EENY-321 (originally published as DPI Entomology Circular 354), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

Shoot Damage

Abstract The exotic pine shoot beetle, Tomicus piniperda [L.] (Coleoptera: Scolytidae) is a Eurasian pest of pines that was first discovered in North America in 1992 near Cleveland, Ohio. It has since been found in at least 72 counties in Michigan, 285 additional counties in 11 other north central and eastern states, and the provinces of Ontario and Quebec. We counted injured shoots along linear transects in ten stands of Scotch (Pinus sylvestris L.), red (Pinus resinosa Aiton), and jack pine (Pinus banksiana Lambert) in lower Michigan (30 stands total) to estimate the frequency of shoot damage attributable to pine shoot beetle, other shoot-feeding insects, weather, and other damaging agents from 1997 to 1999. Fifteen of the stands were located in southwestern counties where pine shoot beetle has been established for at least 8 to 10 yr. The other 15 stands were in northern counties where pine shoot beetle establishment is more recent. In the southwestern stands, pine shoot beetle killed significantly more shoots in Scotch pine stands than in red or jack pine stands, and injured more shoots in Scotch pine stands than all other insects combined. Two of these Scotch pine stands were near an area with an abundance of Scotch pine brood material available to parent beetles. Damage in these two stands averaged roughly 10 to 12 shoots per m2 in 1998 and 1999, compared with 0.6 to 1.6 shoots per m2 in other Scotch pine stands, and less than 0.2 shoots per m2 in nearby red or jack pine stands. Pine shoot beetle was at very low or undetectable levels in northern stands in all years. Shoots injured by three other shoot-feeding insects were occasionally encountered, most often in red pine stands, but caused an insignificant amount of damage. With the exception of the southwestern Scotch pine stands, most of the shoot damage, particularly in northern jack pine stands, was attributable to squirrels or abiotic factors such as wind, ice or snow.

Synergistic Increase

Hylastes opacus Erichson is a recently introduced bark beetle in North America (Bright and Skidmore 1997; Hoebeke 1994; Rabaglia and Cavey 1994; Wood 1992). It is widely distributed in the Palearctic region, where it usually breeds in stumps and roots of dead or dying pines (Pinus) and occasionally other conifers (Hoebeke 1994). Like many species of bark beetles, H. opacus uses host volatiles as cues to search for suitable host material for feeding and establishment of broods. Hoebeke (1994) reported the attraction of H. opacus to ethanol-baited logs of Scots pine (Pinus sylvestris L.) and red pine (Pinus resinosa Ait.) in New York, United States of America. In Sweden, Schroeder and Lindelöw (1989) observed H. opacus responding to (−)-α-pinene and to ethanol released separately, but a synergistic increase in response did not occur when these two compounds were released together. In later experiments, Lindelöw et al. (1993) found that traps baited with ethanol alone, ethanol + (−)-α-pinene, and spruce turpentine caught significantly more H. opacus than unbaited traps. In these experiments, (−)-α-pinene alone was not attractive, and when (−)-α-pinene was combined with spruce turpentine and ethanol, it reduced catches of H. opacus. In 2002, while investigating attractants for the pine shoot beetle, Tomicus piniperda (L.) (TM Poland, P de Groot, S Burke, D Wakarchuk, RA Haack, and RW Nott, unpublished data), we unexpectedly found significant numbers of H. opacus in one of our experiments. Here we report that H. opacus is strongly attracted to nonanal.

The pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytidae), was first discovered in North America in 1992, and by the late 1990s it was associated with tree mortality and stand decline throughout southern Ontario. To assess whether this beetle was capable of killing vigorous trees (a primary pest) or would kill only trees already stressed (a secondary pest), we surveyed 43 sites of varying Scots pine (Pinus sylvestris L.), red pine (Pinus resinosa Ait.), and jack pine (Pinus banksiana Lamb.) composition. Specifically, our objective was to determine the relationship between tree and site characteristics and the number of stem and shoot attacks by T. piniperda in southern Ontario. An abundance of recently dead and low-vigour pine trees increased susceptibility of sites to stem and shoot attacks by T. piniperda. Significant negative linear relationships were detected between the number of beetle attacks and the mean height, age, diameter at breast height, basal area, canopy cover, duff depth, and radial growth increments. Pure red pine sites had significantly fewer attacks than sites of pure Scots pine and mixed jack pine, which was attributed to differences in tree vigour and forest management. Tomicus piniperda appears to be a secondary bark beetle in southern Ontario, successfully colonizing only recently dead pine trees or trees suffering from stress.

Abstract The state of Maryland identified its first case of COVID-19 on March 5, 2020. The Baltimore Convention Center (BCCFH) quickly became a selected location to set up a 250-bed inpatient Field Hospital and Alternate Care Site. In contrast to other field hospitals throughout the United States, the BCCFH remained open throughout the pandemic and took on additional COVID-19 missions, including community SARS-CoV-2 diagnostic testing, monoclonal antibody infusions for COVID-19 outpatients, and community COVID-19 vaccinations. At the time of publication, the BCCFH had cared for 1,478 COVID-19 inpatients, performed 108,155 COVID-19 tests, infused 2,166 COVID-19 patients, and administered 115,169 doses of COVID-19 vaccine. To prevent the spread of pathogens during operations, infection prevention and control guidelines were essential to ensure the safety of staff and patients. Through multi-agency collaboration, utilization of infection prevention best practices, and answering what we describe as “PPE-ESP”, an operational framework was established to reduce infection risks for those providing or receiving care at the BCCFH during the COVID-19 pandemic.

How do societies and states represent the historical, moral, and political weight of the terrorist attacks they have had to face? Having suffered in recent years from numerous terrorist attacks on their soil originating from jihadist movements, and often led by actors who were also their own citizens, France and the United States have set up—or seek to do so—places of memory whose functions, conditions of creation, modes of operation, and nature of the messages sent may vary. Three of the main protagonists and initiators of two museum-memorial projects linked to terrorist attacks have agreed to deliver their visions of the role and of the political, social, and historical context in which these projects have emerged. Allowing to observe similarities and differences between the American and French approach, this interview sheds light on the place of memory and feeling in societies struck by tragic events and seeking to cure their ills through memory and commemoration.

Survival, total height and diameter at breast height (DBH) were measured in the fall of 2005 in a 48-year-old red pine (Pinus resinosa Ait.) provenance trial growing in northwestern Ontario. There was significant variation in both height and diameter among the 23 provenances. Generally, westerly provenances performed well while those from the Maritime Provinces exhibited relatively poor growth. Considering that the plantation is at the northern biological range of red pine, survival was high, averaging 96% after 48 years. Provenances with the best growth rates exceeded a volume of 420 m3 ha-1. Some provenances from Minnesota and Wisconsin as well as Fort Frances, Ontario exhibited superior growth and should be considered as seed sources for future planting programs in northwestern Ontario.

Interpretive Flexibility

The article examines science-policy conversations mediated by social science in attempts to govern, or set up terms for, scientific research. The production of social science research accounts about science faces challenges in the domains of emerging technosciences, such as nano. Constructing notions of success and failure, participants in science actively engage in the interpretation of policy notions, such as the societal relevance of their research. Industrial engagement is one of the prominent themes both in policy renditions of governable science, and in the participants’ attempts to achieve societally relevant research, often oriented into the future. How do we, as researchers, go about collecting, recording, and analyzing such future stories? I examine a series of recent interviews conducted in a number of US universities, and in particular at a university campus on the West Coast of the United States. The research engages participants through interviews, which can be understood as occasions for testing the interpretive flexibility of nano as “good” scientific practice and of what counts as societal relevance, under what circumstances and in view of what kind of audiences.
