    Ethanol and (–)-A-Pinene: Attractant Kairomones for Some Large Wood-Boring Beetles in Southeastern USA

    J Chem Ecol (2006) DOI 10.1007/s10886-006-9037-8 Ethanol and (–)-a-Pinene: Attractant Kairomones for Some Large Wood-Boring Beetles in Southeastern USA Daniel R. Miller Received: 12 September 2005 /Revised: 12 December 2005 /Accepted: 2 January 2006 # Springer Science + Business Media, Inc. 2006 Abstract Ethanol and a-pinene were tested as attractants for large wood-boring pine beetles in Alabama, Florida, Georgia, North Carolina, and South Carolina in 2002–2004. Multiple-funnel traps baited with (j)-a-pinene (released at about 2 g/d at 25–28-C) were attractive to the following Cerambycidae: Acanthocinus nodosus, A. obsoletus, Arhopalus rusticus nubilus, Asemum striatum, Monochamus titillator, Prionus pocularis, Xylotrechus integer, and X. sagittatus sagittatus. Buprestis lineata (Buprestidae), Alaus myops (Elateridae), and Hylobius pales and Pachylobius picivorus (Curculionidae) were also attracted to traps baited with (j)-a-pinene. In many locations, ethanol synergized attraction of the cerambycids Acanthocinus nodosus, A. obsoletus, Arhopalus r. nubilus, Monochamus titillator, and Xylotrechus s. sagittatus (but not Asemum striatum, Prionus pocularis,orXylotrechus integer)to traps baited with (j)-a-pinene. Similarly, attraction of Alaus myops, Hylobius pales, and Pachylobius picivorus (but not Buprestis lineata) to traps baited with (j)-a- pinene was synergized by ethanol. These results provide support for the use of traps baited with ethanol and (j)-a-pinene to detect and monitor common large wood- boring beetles from the southeastern region of the USA at ports-of-entry in other countries, as well as forested areas in the USA.

    Effects of. Prescribed Fire and Fire Surrogates on Saproxylic Coleoptera in the Southern Appalachians of North Carolina 1 2 Joshua W. Campbell , James L. Hanula and Thomas A. Waldrop 3 USDA Forest Service, Southern Research Station, 320 Green St., Athens, Georgia 30602-2044 USA J. Entomol. Sci. 43(1): 57-75 (January 2008) Abstract We examined the effects of forest management practices (prescribed burning, me­ chanical, and prescribed burn plus mechanical) on saproxylic forest Coleoptera in the southern Appalachian Mountains of North Carolina. During the 2-yr study, we captured 37,191 Coleoptera with baited multiple-funnel traps and pipe traps, comprising 20 families and 122 species that were used for our analysis. Saproxylic beetle numbers increased greatly from the first year to the second year on all treatments. Species richness and total abundance of Coleoptera were not significantly affected by the treatments, but several families (e.g., Elateridae, Cleridae, Trogositi­ dae, Scolytidae) were significantly more abundant on treated plots. Abundances of many spe­ cies, including various species of Scolytidae were significantly affected by the treatments. How­ ever, these scolytids (Hylastes salebrosus Eichoff, Ips grandicollis Eichoff, Xyloborinus saxeseni Ratzburg, Xyleborus sp., Xyleborus atratus Eichoff) did not respond in the same way to the treatments. Likewise, other Coleoptera such as Pityophagus sp. (Nitidulidae), Hylobius pales Herbst (Curculionidae), and Xylotrechus sagittatus Germar (Cerambycidae) also varied in their responses to the treatments. Species richness was not significantly different for the spring 2003 trapping seasons, but the fall 2003 sample had a higher number of species on mechanical shrub removal only and mechanical shrub removal plus prescribed burning plots compared with con­ trols.

    Pheromone-Based Disruption of Eucosma Sonomana and Rhyacionia Zozana (Lepidoptera: Tortricidae) Using Aerially Applied Microencapsulated Pheromone1

    361 Pheromone-based disruption of Eucosma sonomana and Rhyacionia zozana (Lepidoptera: Tortricidae) using aerially applied microencapsulated pheromone1 Nancy E. Gillette, John D. Stein, Donald R. Owen, Jeffrey N. Webster, and Sylvia R. Mori Abstract: Two aerial applications of microencapsulated pheromone were conducted on five 20.2 ha plots to disrupt western pine shoot borer (Eucosma sonomana Kearfott) and ponderosa pine tip moth (Rhyacionia zozana (Kearfott); Lepidoptera: Tortricidae) orientation to pheromones and oviposition in ponderosa pine plantations in 2002 and 2004. The first application was made at 29.6 g active ingredient (AI)/ha, and the second at 59.3 g AI/ha. Baited sentinel traps were used to assess disruption of orientation by both moth species toward pheromones, and E. sonomana infes- tation levels were tallied from 2001 to 2004. Treatments disrupted orientation by both species for several weeks, with the first lasting 35 days and the second for 75 days. Both applications reduced infestation by E. sonomana,but the lower application rate provided greater absolute reduction, perhaps because prior infestation levels were higher in 2002 than in 2004. Infestations in treated plots were reduced by two-thirds in both years, suggesting that while increas- ing the application rate may prolong disruption, it may not provide greater proportional efficacy in terms of tree pro- tection. The incidence of infestations even in plots with complete disruption suggests that treatments missed some early emerging females or that mated females immigrated into treated plots; thus operational testing should be timed earlier in the season and should comprise much larger plots. In both years, moths emerged earlier than reported pre- viously, indicating that disruption programs should account for warmer climates in timing of applications.

    COMMUNITY AND ECOSYSTEM ECOLOGY Colonization of Artificially Stressed Black Walnut Trees by Ambrosia Beetle, Bark Beetle, and Other Weevil Species (Coleoptera: Curculionidae) in Indiana and Missouri 1,2 3 1 4 SHARON E. REED, JENNIFER JUZWIK, JAMES T. ENGLISH, AND MATTHEW D. GINZEL Environ. Entomol. 44(6): 1455–1464 (2015); DOI: 10.1093/ee/nvv126 ABSTRACT Thousand cankers disease (TCD) is a new disease of black walnut (Juglans nigra L.) in the eastern United States. The disease is caused by the interaction of the aggressive bark beetle Pityophthorus juglandis Blackman and the canker-forming fungus, Geosmithia morbida M. Kolarik, E. Freeland, C. Utley & Tisserat, carried by the beetle. Other insects also colonize TCD-symptomatic trees and may also carry pathogens. A trap tree survey was conducted in Indiana and Missouri to characterize the assemblage of ambrosia beetles, bark beetles, and other weevils attracted to the main stems and crowns of stressed black walnut. More than 100 trees were girdled and treated with glyphosate (Riverdale Razor Pro, Burr Ridge, Illinois) at 27 locations. Nearly 17,000 insects were collected from logs harvested from girdled walnut trees. These insects represented 15 ambrosia beetle, four bark beetle, and seven other weevil species. The most abundant species included Xyleborinus saxeseni Ratzburg, Xylosandrus crassiusculus Motschulsky, Xylosandrus germanus Blandford, Xyleborus affinis Eichhoff, and Stenomimus pallidus Boheman. These species differed in their association with the stems or crowns of stressed trees. Multiple species of insects were collected from individual trees and likely colonized tissues near each other. At least three of the abundant species found (S. pallidus, X.

    Forest Tortricids Trapped Using Eucosma and Rhyacionia Synthetic Sex Attractants

    Journal of the Lepidopterists' Society 39(1), 1985, 26-32 FOREST TORTRICIDS TRAPPED USING EUCOSMA AND RHYACIONIA SYNTHETIC SEX ATTRACTANTS R. E. STEVENS,I C. SARTWELL,2 T. W. KOERBER,3 J. A. POWELL,4 G. E. DATERMAN,2 AND L. L. SOWER2 ABSTRACT. Moths of 31 non-target species of Tortricidae (30 Olethreutinae, 1 Tor­ tricinae) were lured to synthetic Eucosma and Rhyacionia sex attractants deployed in pine forests throughout 12 states in the western U.S. Genera represented include Petrova, Barbara, Phaneta, Eucosma, Epiblema, Epinotia, Ancylis, Dichrorampha, Sereda, Grapholita, Cydia, and Decodes, as well as a new genus near Rhyacionia. In 1977 and 1978 we conducted an extensive trapping survey in pine forests in the western United States, using synthetic sex attractants. The primary objective was to learn more about geographical distribution and host relationships of Eucosma sonomana Kearfott and species of Rhyacionia. While the major results have been published (Sartwell et aI., 1980; Stevens et aI., 1980), a variety of other moths, largely ole­ threutines, also responded to the lures. These were saved and identified when their numbers indicated more than chance captures. Generally, a minimum of 4-6 similar moths at a trapping location was considered sufficient to indicate attraction was not incidental, although in some instances we recovered fewer. The catches reported here provide clues regarding pheromone chemistry of and possible taxonomic relation­ ships among certain species. The information may be useful for future studies on these and related species. It also provides range extensions for some of the species captured. METHODS Details of the methods, including trapping periods and precise trap locations for most collections, are presented in the previously cited works (Sartwell et aI., 1980; Stevens et aI., 1980).

    RELATIONSHIPS BETWEEN DEAD WOOD AND ARTHROPODS IN THE SOUTHEASTERN UNITED STATES by MICHAEL DARRAGH ULYSHEN (Under the Direction of James L. Hanula) ABSTRACT The importance of dead wood to maintaining forest diversity is now widely recognized. However, the habitat associations and sensitivities of many species associated with dead wood remain unknown, making it difficult to develop conservation plans for managed forests. The purpose of this research, conducted on the upper coastal plain of South Carolina, was to better understand the relationships between dead wood and arthropods in the southeastern United States. In a comparison of forest types, more beetle species emerged from logs collected in upland pine-dominated stands than in bottomland hardwood forests. This difference was most pronounced for Quercus nigra L., a species of tree uncommon in upland forests. In a comparison of wood postures, more beetle species emerged from logs than from snags, but a number of species appear to be dependent on snags including several canopy specialists. In a study of saproxylic beetle succession, species richness peaked within the first year of death and declined steadily thereafter. However, a number of species appear to be dependent on highly decayed logs, underscoring the importance of protecting wood at all stages of decay. In a study comparing litter-dwelling arthropod abundance at different distances from dead wood, arthropods were more abundant near dead wood than away from it. In another study, ground- dwelling arthropods and saproxylic beetles were little affected by large-scale manipulations of dead wood in upland pine-dominated forests, possibly due to the suitability of the forests surrounding the plots.

    Ophiostomoid Fungi Associated with Bark Beetle Species Colonizing White Spruc in the Great Lakes Region

    Invited Paper Beetle - Fungal Interactions Workshop Proceedings of Western International Forest Disease Work Conference September, 1999, Breckenridge, CO Ophiostomoid Fungi Associated with Bark Beetle species Colonizing White Spruc in the Great Lakes Region K.E. Haberkern, K.F. Raffa, Entomology, University of Wisconsin, Madison, and B.L. Illman, USDA Forest Service, Forest Products Laboratory, Madison, WI White spruce plantations in various State and National forests in Northern Minnesota, Northern Wisconsin and the Upper -Peninsula of Michigan were used to collect bark beetles and identify their fungal associates. Trees were felled twice during the summer flight season and left on the forest floor for 6 weeks, in order, to be colonized by beetles (May and July). In the Fall insects were reared from the felled trees and a microbial dilution plating technique was used to isolate Ophiostomiod fungi from live bark beetles (Klepzig 1991). Fungi were also isolated from colonized and uncolonized host tissue. The felled trees were predominantly colonized by nonaggressive, secondary bark beetle species: Crypturgus borealis, Dryocetes affaber, Dryocetes autographus, Ips pini, and Polygraphus rufipennis., Only one aggressive species was found, Dendroctonus rufipennis. There were over 14,500 secondary beetles and only 30 Dendroctonus rufipennis that emerged from the 55 felled white spruce trees. The dispersal time varied among insect species. Dryocetes affaber heavily colonized trees felled in July and only sparsely colonized the trees felled in May (7 to 1). Polygraphus rufipennis was found in greater abundance in the early set oftrees (6 to 1). Overall, halfthe beetle species colonized the early set of felled trees (May) and half colonized the trees felled in July (3 to 3).

E-mail: [email protected] 3Corresponding author. Department of Biology, University of Bergen, Bergen, Norway. E-mail: [email protected] Abstract Crypturgus subcribrosus Eggers is removed from synonymy under C. cinereus (Herbst) and reinstated as a valid species based on evidence from DNA sequence data and morphological features. Phylogenetic analyses of Elongation Factor 1α and Cytochrome Oxidase I sequences in conjunction with morphological characters revealed a sister relationship between C. subcribrosus and two Nearctic species of Crypturgus, with C. cinereus unrelated to any of these taxa. Type material of C. cinereus has been located and lectotype with paralectotypes are designated. Amended diagnoses that include DNA barcodes are presented for C. subcribrosus and C. cinereus together with an identification key to the Fen- noscandian species of Crypturgus. Key words: Cytochrome Oxidase I, Coleoptera, Crypturgus, Curculionidae, DNA barcodes, Elongation Factor 1α, phy- logeny, Scolytinae Introduction Species of the bark beetle genus Crypturgus Erichson breed in conifers throughout the Holarctic region.
