Odonata Of Coastal Peatland Habitats Adjacent To Lake Superior In Wisconsin, Robert B. Dubois, Julie M. Pleski, William A. Smith, Eric J. Epstein

The Great Lakes Entomologist

We sampled adults and exuviae of Odonata in eleven coastal fens and poor fens near Lake Superior in Douglas, Bayfield, and Ashland counties in Wisconsin to determine species that were breeding in these areas, and gain knowledge about their relative abundances, flight periods, and nymphal habitats. The flora in these fens was characterized by mats of Sphagnum mosses, a variety of ericaceous shrubs, and a number of sedges, among which Carex lasiocarpa Ehrhart (slender sedge) was most dominant. We averaged seven visits per site from early June through September, 2004, to cover the flight periods of most species of Odonata …

Habitat Distribution Of Carabid Beetles (Coleoptera: Carabidae) In Northern Hardwood Forests Of Michigan, Holly A. Petrillo, John A. Witter

The Great Lakes Entomologist

We compared carabid beetle communities in northern hardwood forests and divided these forests into three categories based on overstory composition and geographic location: Northern red oak-American beech (Quercus rubra L.-Fagus grandifolia Ehrh.) in the Lower Peninsula (OBLP), sugar maple- American beech (Acer saccharum Marsh.) in the Lower Peninsula (MBLP), and sugar maple- American beech in the Upper Peninsula (MBUP). Carabid beetles were collected using pitfall traps in 36 stands in 2003-2004. We found that carabid composition changed throughout the collection periods. Pterostichus pensylvanicus LeConte and Sphaeroderus lecontei Dejean comprised 76% of the trap catches in May while Synuchus impunctatus (Say) …

Spatiotemporal Variation Of Violet-Feeding Large Fritillaries (Euptoieta, Speyeria) (Lepidoptera: Nymphalidae) In Central And Northern Wisconsin, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

We analyzed the relative abundance of the large fritillaries Euptoieta claudia (Cramer) (immigrant), Speyeria cybele (Fabricius) and S. atlantis (Edwards) (generalists), S. aphrodite (Fabricius) (grassland species), and S. idalia (Drury) (prairie specialist) in transect surveys at grasslands and pine barrens during 1990-2006 for variation and correlation over time (measured both as chronological year and as years since last management treatment) among six subregions in central and northern Wisconsin. Population trends (correlations of abundance with chronological year) were few and not significantly skewed toward either negative or positive trends. Spatial synchrony between pairs of subregions was significantly different among species, and …

The Native And Introduced Bark And Ambrosia Beetles Of Michigan (Coleoptera: Curculionidae, Scolytinae), Anthony I. Cognato, Nicolas Barc, Michael Philip, Robert Mech, Aaron D. Smith, Eric Galbraith, Andrew J. Storer, Lawrence R. Kirkendall

The Great Lakes Entomologist

Our knowledge of the biogeography of Scolytinae of eastern temperate North America is very patchy. We used data from hand collecting, trapped material (from 65 of 83 counties), and museum collections, supplemented by literature records, to compile a list comprising 107 bark beetle species in 45 genera for Michigan, a state with an especially rich diversity of woody plants. We provide detailed collection data documenting 32 species not previously catalogued for Michigan, 23 of which are new state records; the genera Trypophloeus and Trischidias are reported from Michigan for the first time. Fifteen Michigan scolytines are not native to North …

Fleas Of The Norway Rat In The Superior, Wisconsin, Harbor Area (Siphonaptera: Ceratophyllidae, Hystrichopsyllidae), Darol L. Kaufmann, Norman D. Radtke

The Great Lakes Entomologist

The occurrence of the fleas of the Norway rat, Rattus noruegicus (Berkenhout) was monitored in Superior, Wisconsin, for 12 months. A total of 441 fleas was recovered from 300 rat hosts. Nosopsyllus fasciatus (Bosc), the northern rat flea, was the most abundant species found (94.1%) while Ctenophthalmus pseudagyrtes pseudagyrtes Baker (5.4%) and Megabothris asio asio (Baker) (0.5%) were also present. The flea index was highest (4.8) in July and lowest (0.2) in February and March. Forty-four percent of the rats examined were infested.

Simulation Of The Effects Of Stand Factors On Spruce Budworm (Lepidoptera: Tortricidae), W. P. Kemp, J. P. Nyrop, G. A. Simmons

The Great Lakes Entomologist

A model was developed to simulate the life history of instar-I through instar-I1 spruce budworm, Choristoneura fumiferana (Clemens). Particular emphasis was given to the redistribution phases during spring and fall and the factors affecting budworm survival. Analyses included the effects of aggregated stand types, temperature, cloud cover, open areas, and the species distribution, on redistribution mortality. Of those stand factors examined, open area and non-host percentages were the most important in regulating redistribution survival.

Size Reduction Southward In Michigan's Mustard White Butterfly, Pieris Napi (Lepidoptera: Pieridae), W. H. Wagner Jr., Michael K. Hansen

The Great Lakes Entomologist

[Excerpt]

The mustard white, Pieris napi (Linnaeus) is generally considered to be a circumboreal species or species-complex. Much disagreement exists regarding the classification in this group, the members of which are extremely diverse, especially in Eurasia. There is evidently "a continuous range of differentiation, from local populations, through subspecies, to species, which nomenclature cannot fully reflect" (Bowden 1972). In North America the major controversy has been whether the so-called West Virginia white, P. virginiensis Edwards, should be separated as a distinct species. Most writers today agree that it should. Of the mustard white in the Great Lakes area, the local …

An Annotated List Of The Checkered Beetles (Coleoptera: Cleridae) Of Michigan, D.C. L. Gosling

The Great Lakes Entomologist

[Excerpt]

The checkered beetles (Cleridae) have been included in local lists of Michigan Coleoptera by Andrews ( 1916, 192 1, 1929), Hatch (1924), Hubbard and Schwarz (1878). LeConte (1850), and Wolcott (1909). The present list is the first to include records from throughout the state, and is based on the collections of the University of Michigan Museum of Zoology (UMMZ), those of the Department of Entomology, Michigan State University (MSUC), and the private collections of E. F. Giesbert, D. K. Young, and the author. This list records 35 species of Cleridae from the state, and I believe it is essentially …

Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Within the framework of an ongoing comparative genomic study of global butterfly diversity, we construct phylogenetic trees combining all protein-coding genes assembled from the whole genome shotgun data. When viewed in the context of current taxonomy and phenotypic knowledge, the genome-wide phylogeny points to further advances in butterfly systematics, which are presented here. We assign major clades with comparable levels of genetic divergence to the same taxonomic rank and apply criteria involving relative population divergence and gene flow to define species boundaries. As a result, one genus, 13 subgenera, 62 species, and five subspecies are proposed as new (type species …

Ammonia Regulation In Aedes Taeniorhynchus, A Salt-Water Mosquito, Joseph Edmonds

Undergraduate Honors Theses

The salt tolerant mosquito species Aedes taeniorhynchus has been observed in high salinity and ammonia conditions. Previous studies indicate Na+/K+ ATPase (NKA), the proton pump vacuolar-type H+ ATPase (VHA) and sodium-dependent cation-chloride cotransporters (NKCC’s) in sodium secretion in larval Aedes taeniorhynchus. However ammonia transporter such as Rh-protein, Amt1, and Amt2 have only been characterized in Aedes taeniorhynchus’s fresh water relative Aedes aegypti. Our research exhibits the expression of these transporters in A.taeniorhynchus using immunohistochemistry techniques. Evidence of VHA and NKA function in ammonia transport was characterized in vivo using drug antagonists in varying saline and ammonia concentrations. Ammonia flux rates …

Potential Economic Impact Of Grapevine Phylloxera (Hemiptera: Phylloxeridae) On Western Australian Winegrapes, David C. Cook, Andrew S. Taylor, Peter S. Gardiner, Rodrigo Pires, Hamish L R Mckirdy, Karen W. Holmes, Helen Spafford

Viticulture Research Articles

Grapevine phylloxera Daktulosphaira vitifoliae Fitch (Hemiptera: Phylloxeridae) has been present in Australia for almost 150 years but has not spread to south-west Western Australia, in part due to the relative isolation of the region. Recent improvements in tourist access, with interstate flights now arriving at Busselton Margaret River Airport, raise concerns about potential phylloxera introductions via wine tourism. In this paper, we simulate the potential economic impact on the Western Australian winegrape industry following a hypothetical arrival event in the Margaret River wine region. We use soil texture maps to assess the suitability of winegrape-growing areas to phylloxera establishment and …
