Carriere, and Carolina hemlock, T. caroliniana, are shade- tolerant and long-lived tree species found in eastern North America. Both survive well in the shade of an overstory, although eastern hemlock has adapted to a variety of soil types and now extends from Nova Scotia across southern Ontario to northern Michigan and northeastern Minnesota, south- ward into northern Georgia and Alabama, and westward from central New Jersey to the Appala- chian Mountains. Carolina hemlock is a relict species limited to a small area in the southern range of eastern hemlock. Hemlock stands create an environment with many unique ecological and aesthetic charac- teristics, although due to their long life, they are susceptible to a number of insect pests, including hemlock woolly adelgid (Adelges tsugae Annand), elongate hemlock scale (Fiorinia externa), hem- lock looper (Lambdina fiscellaria), and hemlock borer (Melanophila flvoguttata). In recent years (from the 1980s to the present), hemlock mortality and widespread pre- emptive logging caused by the hemlock woolly adelgid has roused the issue of the future of hem- lock. These hemlock forests will be replaced by hardwood species, and resulting local changes to the environment will have detrimental impacts for terrestrial and aquatic ecosystems. In response to this threat to hemlocks in eastern North America, the U.S. Department of Agriculture Forest Service and numerous state, university, and private organizations have responded with the development of a coordinated effort to manage the hemlock woolly adelgid and other III insect pests associated with hemlock. There have been two recent symposia addressing all aspects of hemlock woolly adelgid: in 1995, First Hemlock Woolly Adelgid Review, Charlottesville, Virginia; and in 2002, Hemlock Woolly Adelgid in the Eastern United States Symposium, East Brunswick, New Jersey. The latest meeting, held in February of 2005, the Third Symposium on Hemlock Woolly Adelgid in the east- ern United States, Asheville, North Carolina, also included the presentation of information on the biology and impacts of elongate hemlock scale and the balsam woolly adelgid. Articles and ab- stracts in these proceedings represent the range of recent and current studies addressing this ongo- ing concern.

Abstract With the increase in the availability of genomic data, sequences from different loci are usually concatenated in a supermatrix for phylogenetic inference. However, as an alternative to the supermatrix approach, several implementations of the multispecies coalescent (MSC) have been increasingly used in phylogenomic analyses due to their advantages in accommodating gene tree topological heterogeneity by taking account population-level processes. Moreover, the development of faster algorithms under the MSC is enabling the analysis of thousands of loci/taxa. Here, we explored the MSC approach for a phylogenomic dataset of Insecta.

First noticed in the mountains above Farmington Canyon and near Powder Mountain Resort, it has Dieback and decline of subalpine fir due to attack by balsam woolly adelgid. Photo credit: Darren McAvoy. 2017, forest health professionals visited Farmington Canyon on the ground and found branch node swelling (a node is where branch structures come together) and old deposits of woolly material on mature subalpine fir trees. Suspected to have originated in the Caucasus Mountains between Europe and Asia, BWA was first detected in North America in Maine, in 1908, and in California about 20 years later. It was detected in Idaho near Coeur d’Alene in 1983 and has since spread across northern Idaho. It is believed that separate invasions of subspecies or races of BWA may differentially impact tree host species. Dieback of subalpine fir, pacific silver (Abies amabilis) and grand fir (A. grandis) in Idaho is widespread. In the western Payette National Forest, north of Boise, an estimated 70% of subalpine fir trees are dead and falling down.

With an increasingly skeptical society to pesticides it is important that scientists and non-specialists (farmers and neighbours) meet and discuss their ideas about insecticide use and risks. This is necessary because the public’s perception of risks may well diverge significantly from that of specialists. In the periurban areas (the urban fringe) these problems and divergent opinions are likely to be more pronounced than in the rural areas. This review paper is also discussing the insect pest migrations and trap cropping with a view to find out whether insecticide application in field crops (e.g. oilseed rape) affects pest density in the adjacent garden crops (e.g. radish). Preface This introductory paper is a review based on references from libraries, internet and personal communication.

Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the Torix group, appear to reside exclusively in invertebrates and protists with no secondary vertebrate host. Importantly, little is known about the diversity or host range of Torix group Rickettsia.

This program allows students to learn about the rich diversity of plants and animals in the southern Appalachians. The field site is located on the Highlands Plateau, North Carolina, near the junction of North Carolina, South Carolina and Georgia. The plateau is surrounded by diverse natural areas which create an ideal setting to study different aspects of land use change and threats to biodiversity. The Highlands Plateau is a temperate rainforest of great biodiversity, a patchwork of rich forests, granite outcrops, and wet bogs. Many rare or interesting species can be found in the area, with some being endemic to a specific stream or mountaintop. Some of these are remnants of northern species that migrated south during the last ice age; others evolved to suit a particular habitat, with a slightly different species in each stream.

  • The Biology of the Predator Complex of the Filbert Aphid, Myzocallis Coryli
    AN ABSTRACT OF THE THESIS OF Russell H. Messing for the degree of Master of Science in Entomology presented in July 1982 Title: The Biology of the Predator Complex of the Filbert Aphid, Myzocallis coryli (Goetze) in Western Oregon. Abstract approved: Redacted for Privacy M. T. AliNiiee Commercial filbert orchards throughout the Willamette Valley were surveyed for natural enemies of the filbert aphid, Myzocallis coryli (Goetze). A large number of predaceous insects were found to prey upon M. coryli, particularly members of the families Coccinellidae, Miridae, Chrysopidae, Hemerobiidae, and Syrphidae. Also, a parasitic Hymenopteran (Mesidiopsis sp.) and a fungal pathogen (Triplosporium fresenii) were found to attack this aphid species. Populations of major predators were monitored closely during 1981 to determine phenology and synchrony with aphid populations and to determine their relative importance. Adalia bipunctata, Deraeocoris brevis, Chrysopa sp. and Hemerobius sp. were found to be extremely well synchronized with aphid population development cycles. Laboratory feeding trials demonstrated that all 4 predaceous insects tested (Deraeocoris brevis, Heterotoma meriopterum, Compsidolon salicellum and Adalia bipunctata) had a severe impact upon filbert aphid population growth. A. bipunctata was more voracious than the other 3 species, but could not live as long in the absence of aphid prey. Several insecticides were tested both in the laboratory and field to determine their relative toxicity to filbert aphids and the major natural enemies. Field tests showed Metasystox-R to be the most effective against filbert aphids, while Diazinon, Systox, Zolone, and Thiodan were moderately effective. Sevin was relatively ineffective. All insecticides tested in the field severely disrupted the predator complex.
