Jutta Arctic (Oeneis Jutta) (Lepidoptera: Nymphalidae) Populations In Central And Northern Wisconsin: Localized Butterfly Populations In A Naturally Fragmented Landscape, Scott R. Swengel, Ann B. Swengel

The Great Lakes Entomologist

We recorded Oeneis jutta (Hübner) (Lepidoptera: Nymphalidae) at 60 of 78 peatland sites in central and northern Wisconsin on butterfly transect surveys on 113 dates during 2002–11. Additional observations come from informal observations on 19 dates in 12 years during 1987–2001. Most sites where we did not find O. jutta had little survey effort. The areas with the lowest O. jutta abundance (coastal and inland Bayfield County) had the shortest flight periods recorded in this study. O. jutta abundance negatively and significantly correlated with increasing wind speed and later times of day. O. jutta abundance significantly varied by bog vegetation …

The Effect Of Acclimation Temperature On The Critical Thermal Maximum Of A Cold-Water Population Of Pteronarcys Dorsata (Say) (Plecoptera: Pteronarcyidae), Logan Shoup, David C. Houghton

The Great Lakes Entomologist

The critical thermal maximum (CTmax) of Pteronarcys dorsata (Say) acclimated in the laboratory to 5 different temperatures ranging from 4 to 28°C was 34.7–36.6°C. A 6th temperature (33°C) resulted in 100% mortality during the acclimation period. Although its CTmax values rank P. dorsata as moderately sensitive to thermal stress, the < 2°C difference over a 7-fold increase in acclimation temperature suggests only a weak ability to adapt to warming conditions relative to other tested aquatic insect species. This stenothermy in P. dorsata was likely due to the consistently cool stream in which this populations lives. Our results suggest that cold-water populations are particularly susceptible to thermal alterations. They also provide the first CTmax values for a species of pteronarcyd stonefly and the first of any aquatic insect over such a …

Observations On Egg Parasitism Of Aeshna Tuberculifera (Odonata: Aeshnidae) By Eulophidae, Trichogrammatidae And Mymaridae (Hymenoptera) In Alger County, Michigan, Burton C. Cebulski, Mark F. O'Brien

The Great Lakes Entomologist

Egg parasitoids were reared from a population of Aeshna tuberculifera (Odonata: Aeshnidae) in the Kingston Lake area of Alger County, Michigan, from 1983-2005. Leaves of Iris versicolor were repeatedly used for oviposition during the period of observation, with the result that just a few leaves were targeted by different females. Seven species of parasitic Hymenoptera were reared from 1688 eggs. The cumulative rate of parasitization over the course of the study was 18.4%. Three species of parasitoids were responsible for approximately 96% of the parasitized eggs: Aprostocetus (Ootetrastichus) mymaridis Girault (Eulophidae) (41%); and the Mymaridae Polynema nr. needhami (34%) and …

The Horsehair Worm Gordionus Violaceus (Nematomorpha: Gordiida) In Minnesota, Philip A. Cochran, Jacob D. Zanon, Ben Hanelt

The Great Lakes Entomologist

A sample of 21 Gordionus violaceus (Baird) (Nematomorpha: Gordioidea) was obtained from a puddle in Winona County, southeastern Minnesota. These are the first of this species reported from the upper Midwest. Sex ratio was not significantly different from 50:50 and females and males did not differ significantly in length, but females were of significantly greater diameter than males.

Demonstration Of Sex Pheromones In Anabolia Bimaculata, Hydatophylax Argus, And Nemotaulius Hostilis (Trichoptera: Limnephilidae), David C. Houghton

The Great Lakes Entomologist

The presence of extractable semiochemicals for mate attraction is demonstrated experimentally for the first time in Anabolia bimaculata (Walker), Hydatophylax argus (Harris), and Nemotaulius hostilis (Hagen), three species of limnephilid caddisfly. Each species is also the first member of its respective genus to demonstrate pheromone presence. Sex pheromones appear to be wide- spread within the Trichoptera, although < 1% of species have been tested and there remains substantial research still to be done on pheromone demonstration, chemical composition, and release behavior.

Occurrence Of Diabrotica Undecimpunctata Howardi Barber (Coleoptera: Chrysomelidae) Feeding On Cirsium Pitcheri Flowers, Jordan M. Marshall

The Great Lakes Entomologist

(excerpt)

Diabrotica undecimpunctata howardi Barber (adult = spotted cucumber beetle, immature = southern corn rootworm, Coleoptera: Chrysomelidae) is a polyphagous pest found on a broad range for agricultural plants (Krysan 1986). The larvae are root feeders commonly found on plants in the families Cucurbiaceae (gourds and squashes), Poaceae (grasses, including Zea mays L.), and Fabaceae (legumes, including Medicago sativa L.), and can have significant impact on the crop yield depending on the agricultural system (Campbell and Emery 1967, Brust and House 1990).

The Great Lakes Entomologist

Sitochroa palealis (Denis and Schiffermüller, 1775) (Lepidoptera: Crambidae), a newly detected crambid moth in the United States, is found for the first time in orchard and row crop agroecosystems in Adams and Centre counties, Pennsylvania, during 2011. In Adams County, S. palealis male and female adults were net collected from flowers and found in white pan traps used to sample bee populations near apple orchards, while in Centre County adults were found in wire-cone traps baited with the sex pheromone of the European corn borer (E-strain), Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). Additional records of S. palealis from four Ohio counties …

Impact Of Mecinus Janthinus (Coleoptera: Curculionidae) On The Growth And Reproduction Of Linaria Dalmatica (Scrophulariaceae), Elizabeth J. Goulet, Jennifer Thaler, Antonio Ditommaso, Mark Schwarzländer, Elson J. Shields

The Great Lakes Entomologist

Dalmatian toadflax, Linaria dalmatica (L.) Mill. (Scrophulariaceae), a native to the eastern Mediterranean and Black Sea regions of Europe and Asia, has invaded over one million hectares in the western United States and Canada, in habitats similar to its native range. Once established, the aggressive vegetative growth of the plant allows it to invade undisturbed habitats where it can out-compete most other vegetation, placing native plant communities at risk.

Biological control of L. dalmatica with Mecinus janthinus Thomson (Coleoptera: Curculionidae) has shown promise in the field. In both studies reported in this paper, the presence of insect attack reduced L. …

Diversity And Community Structure Of Stream Insects In A Minimally Disturbed Forested Watershed In Southern Illinois, J. E. Mcpherson, Jacqueline M. Turner, Matt R. Whiles

The Great Lakes Entomologist

The Lusk Creek Watershed, located in Pope County, IL, long has been rec- ognized as a high quality area of biological significance, but surveys of the stream macroinvertebrate fauna have been limited. Thus, a survey of the benthic insect community at 11 sites in the upper portion of Lusk Creek was conducted from May 2003 to April 2005. A total of 20,888 specimens, mostly immatures, were examined during the study and represented eight orders. The Diptera, by far, was the most abundant order, with 18,590 specimens, almost all of which were members of the Chironomidae or Simuliidae. Members of the …

Discontinuity In The Insect Assemblages Of A Northern Lower Michigan Stream, David C. Houghton, Constance M. Brandin, Leila Reynolds, Lindsey L. Elzinga

The Great Lakes Entomologist

We assessed the physicochemical and biological continuity of a 2nd–4th order reach of the Little Manistee River in northern Lower Michigan. Contrary to typical woodland streams, the downstream sites of the river were covered with a dense riparian canopy, whereas the upstream sites were devoid of this canopy due to historical (≥10 ybp) agriculture. Other than slight changes in water temperature and dissolved oxygen, there were no appreciable differences in measured water physicochemistry between the canopied and non-canopied sites. The stream, however, appeared biologically discontinuous as indicated by lower shredder abundance and higher filtering collector abundance at the upstream (non-canopied) …

Attraction Of Agrilus Planipennis (Coleoptera: Buprestidae) And Other Buprestids To Sticky Traps Of Various Colors And Shapes, Toby A. Haack, Robert A. Haack, Therese M. Poland

The Great Lakes Entomologist

The family Buprestidae (Coleoptera) contains numerous economically significant species, including the emerald ash borer (EAB), Agrilus planipennis Fairmaire, first discovered in North America in 2002. Effective traps for monitoring spread and population densities of EAB and other buprestids are needed. Studies were conducted in 2008 to test different colors and shapes of sticky traps baited with manuka oil for capturing EAB and other buprestids. Among different trap shapes, an enlarged purple Agrilus-shaped silhouette (15 cm wide × 55 cm all) attached to a white background (40 cm wide × 60 cm tall) captured the most buprestid species compared to …

Variation In Lepidopteran Occurrence In Hemlock-Dominated And Deciduous-Dominated Forests Of Central Appalachia, L. E. Dodd, Z. Cornett, A. Smith, L. K. Rieske

The Great Lakes Entomologist

Eastern hemlock, (Tsuga canadensis Carrière, Pinaceae), is threatened with extirpation by an exotic invasive herbivore, the hemlock woolly adelgid, (Adelges tsugae Annand, Homoptera: Adelgidae). Given this threat, a broader and more detailed knowledge of the community associated with eastern hem- lock is merited. As Lepidoptera are important members of forest communities, this study was initiated to determine the relative occurrence of Lepidoptera in hemlock-dominated and deciduous-dominated habitats by evaluating abundance, species richness, temporal variation, and composition overlap. Lepidoptera were surveyed using blacklight traps from May – August 2010 at two collection sites in the Appalachian region of eastern …

Pentatomoidea (Hemiptera: Pentatomidae, Scutelleridae) Associated With The Dioecious Shrub Florida Rosemary, Ceratiola Ericoides (Ericaceae), A. G. Wheeler Jr.

The Great Lakes Entomologist

Florida rosemary (Ceratiola ericoides), an ericaceous shrub with needlelike leaves, is characteristic of Florida scrubs and certain other xeric plant communities of well-drained sands. The plant is dioecious, its inconspicuous male and female flowers borne on separate individuals. From 2003 to 2012 (mainly 2007–2012), rosemary was sampled periodically (with all months included at least once during the period) in sand ridges of peninsular Florida and two riverine dunes in southeastern Georgia. Branches of male and female plants were tapped separately into a beating net. Sampling during the final three years was female-plant-biased to facilitate work on fruit- and seed-feeding …

Tymbal Morphology And Co-Ccurrence Of Spartina Sap-Feeding Insects (Hemiptera: Auchenorrhyncha), Stephen W. Wilson

The Great Lakes Entomologist

The exoskeletal morphology of the structures associated with the production of substrate vibrations used for communication was examined for members of three guilds of sap-feeding insects on the cordgrasses Spartina alterniflora Loisel, S. patens (Aiton) Muhl., and S. pectinata Link (Poaceae: Chloridoidea). Measurements of the second abdominal sternite and its apodemes, the “tymbal,” were made for the males of 14 species of planthoppers and 2 species of leafhoppers (Hemiptera: Auchenorrhyncha: Caliscelidae, Cicadellidae, Delphacidae, Derbidae). Morphometric comparisons revealed significant differences among the insect species on each of the cordgrass species. If tymbal morphology reflects definitive features of the vibrational signals then …

The Stink Bugs (Hemiptera: Heteroptera: Pentatomidae) Of Missouri, Robert W. Sites, Kristin B. Simpson, Diane L. Wood

The Great Lakes Entomologist

The stink bug (Hemiptera: Pentatomidae) fauna of Missouri was last treated more than 70 years ago. Since then, many more specimens have become available for study, substantial papers on regional faunas have been published, and many revisions and other taxonomic changes have taken place. As a consequence, 40% of the names from the previous Missouri state list have changed or the taxa have been removed. The fauna of stink bugs known from Missouri based on specimens from museums, other collections, and the literature is presented. Included for each species is a general overview of biological and ecological information, overall distribution, …

Mcphersonarcys, A New Genus For Pentatoma Aequalis Say (Heteroptera: Pentatomidae), Donald B. Thomas

The Great Lakes Entomologist

A new monotypic genus, Mcphersonarcys is erected to hold Pentatoma aequalis Say, a species formerly placed in the genus Hymenarcys. Based on the distribution of 19 character-states Hymenarcys forms a clade with its sister genus Coenus. Both genera are related to the large genus Euschistus. Mcphersonarcys is basal to Euschistus, whereas the clade with Hymenarcys and Coenus is derived. Removal of P. aequalis to a new genus resolves the paraphyly of Hymenarcys sensu lato.
