Terricolous Spiders (Araneae) of Insecticide-Treated Spruce-Fir Forests in West-Central Maine

Spiders of 12 families, 42 genera, and at least 62 species were captured in linear-pitfall traps placed in insecticide-treated (Sevin-4-Oil®, Dipel 4L ®, Thuricide 16B®) and untreated spruce-fIr forests of west-central Maine. Species richness per family ranged from 1 (Theridiidae, Araneidae, Salticidae) to 19 (Erigonidae). Most trapped species were web-spinners (67.2%); most trapped individuals were hunters (75.2%). Lycosidae accounted for 66.1 % of all (n = 887) captured spiders. Total trapped spiders varied among insecticide treatments, sampling dates, and study sites. However, comparison of mean prespray and postspray trap catches indicated no significant reduction (ANOVA, ANCOVA, P 0.05) in terricolous spiders following insecticide treatments. Increases in spider abundance during postspray sampling periods may have masked detection of treatment effects

Persistence of Jack Pine Budworm \u3ci\u3eChoristoneura Pinus Pinus,\u3c/i\u3e (Lepidoptera: Tortricidae) Egg Mass Chorions on Jack Pine Foliage

More than one-fifth of old and nearly one-half of new jack pine budworm egg mass chorions remained on the foliage after one year, and an experienced observer could not determine accurately the age of one-fourth of them. Counts of new egg masses are used to estimate current populations, and large errors could result

Habitats and Spider Prey of \u3ci\u3eDipogon Sayi Sayi\u3c/i\u3e (Hymenoptera: Pompilidae) in Washington County, Maine

Spider wasps were reared from three types of trap-nests deployed in strip-clearcut areas of a spruce-fir-mixed hardwood forest of Maine. Collections of Dipogon sayi sayi from Mooseborn National Wildlife Refuge, Washington County, represent the easternmost records for the United States. Spider prey included females of Misumena vatia, Xysticus emertoni (new prey record), and X. punctatus, and juveniles and penultimate males of Xysticus sp. We found no evidence of nest-site competition between spider wasps and eumenid wasps (Hymenoptera: Eumenidae) that prey on spruce budwornl, Choristoneura fumiferana, when available nesting sites ranged from 320 to 4400

Spruce Budworm and Other Lepidopterous Prey of Eumenid Wasps (Hymenoptera: Eumenidae) in Spruce-Fir Forests of Maine

Three species of eumenid wasps, Ancistrocerus adiabatus, Ancistrocerus antilope, and Euodynerus Ieucomelas, accepted and provisioned trap-nesting blocks with lepidopterous larvae, A pyralid. Nephopteryx sp., was the most commonly provisioned prey. A. adiabarus and E. leucomelas preyed on late instars of the spruce budworm, Choristoneura fumiferana: however. budworms accounted for only 6% of the provisioned prey. Estimates of budworm population densities before and after wasp predation, and subsample-s of provisioned prey indicated no significant reductions i = 0.065%) in budworm populations attributable to trap-nesting wasps

Field Tests of Kairomones to Increase Parasitism of Spruce Budworm (Lepidoptera: Tortricidae) Eggs by \u3ci\u3eTrichogramma\u3c/i\u3e Spp. (Hymenoptera: Trichogrammatidae)

Hexane extracts of spruce budworm, Choristoneura fumiferana, moth scales, applied at 0.04 moth-gram equivalents/branch and at 0.06 moth-gram equivalents/tree, failed to increase parasitism rates of Trichogramma spp. in two cutover spruce-fir stands in Maine. Releasing Maine-strain T. minutum apparently increased parasitism rates about 20-fold. However, application of kairomone extracts to whole branches and to upper crowns of small trees may have interfered with host-searching behaviors of Trichogramma parasitoids

Expanding alliance: ANZUS cooperation and Asia–Pacific security

Is an alliance conceived as a bulwark against a resurgence of Japanese militarism and which cut its military and intelligence teeth in the Cold War is still relevant to today’s strategic concerns? Overview The alliance between Australia and the US, underpinned by the formal ANZUS Treaty of 1951, continues to be a central part of Australian defence and security thinking and an instrument of American policy in the Asia–Pacific. How is it that an alliance conceived as a bulwark against a resurgence of Japanese militarism and which cut its military and intelligence teeth in the Cold War is still relevant to today’s strategic concerns? The answer is partly—and importantly—that the core values of the ANZUS members are strongly aligned, and successive Australian governments and American presidential administrations have seen great value in working with like-minded partners to ensure Asia–Pacific security. Far from becoming a historical curiosity, today it’s not just relevant, but of greater importance than has been the case in the past few decades. To explore new ideas on how to strengthen the US–Australia alliance, ASPI conducted a high-level strategic dialogue in Honolulu in July this year. Discussions canvassed the future strategic environment; the forthcoming Australian Defence White Paper; budget, sovereignty and expectation risks; and cooperation in the maritime, land, air, cyber, space and intelligence domains. A key purpose of the Honolulu dialogue was to help ASPI develop policy recommendations on the alliance relationship for government. This report is the product of those discussions

Characteristics of Adult General Education Learners and Courses: A Correlational Study on the Elements of Success

The purpose of this study was to determine if a correlation exists among characteristics common to successful adult career and technical students in the traditional classroom setting, the online mode of instruction, and a hybrid of the traditional and distance mode of instructional delivery. A gap in the literature exists, resulting in a lack of knowledge specific to the reasons for success or failure of these adult career and technical students, specifically in relation to mode of instructional delivery: traditional classroom, online, or a hybrid of both. This study is a quantitative correlation study of explanatory and predictive design using archival data from a large and diverse school district in the state of Florida. The dependent variables included the level of student success as indicated by the student’s withdrawal codes; achievement as measured by the difference between initial Test of Adult Basic Education pretest score and final post-test score required to gain admittance to career and technical education program of student choice; length of time required for the Adult Basic Education student to achieve his or her highest level of success as determined by the pre- and post-test TABE score; and number of courses repeated before required post-test scores are attained during the duration of the coursework. The results of the study indicate that a greater number of factors displayed predictive value in distinguishing successful from non-successful face-to-face students. For these students, nine factors could be included in a predictive model that accurately classified approximately 58.5% of the students in terms of success versus non-success. Four factors were found to make unique contributions: age, ethnicity, the number of course attempts, and the difference between the students’ first and last math TABE scores. For the online students, five factors were included in a predictive model that accurately distinguished roughly 64.4% of the students. In the final analysis, only one factor maintained a unique predictor of program success: the number of course attempts

Building Interiors

Building Interiors (BI) with $18 million annual sales has been acquired by Lone Star Supply, another building material distributor. Lone Star's strategy is to leave top management of the acquired firm in place with the expectation of achieving a certain financial performance. BI has failed to do so. One BI top manager has resigned and a second has been demoted. A Lone Star senior manager with a reputation of being a "turnaround specialist" has been appointed BI’s top manager. The case explores this new manager's approach for achieving the required profitability level
