Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) Observed Feeding On Chamaesaracha Sp. In Eastern Colorado., Michael S. Crossley, Benjamin Pélissié, Zachary Cohen, Sean D. Schoville Feb 2018

Leptinotarsa Decemlineata (Coleoptera: Chrysomelidae) Observed Feeding On Chamaesaracha Sp. In Eastern Colorado., Michael S. Crossley, Benjamin Pélissié, Zachary Cohen, Sean D. Schoville

The Great Lakes Entomologist

Egg, larval, and adult life stages of Colorado potato beetle, Leptinotarsa decemlineata (Say), were observed feeding on or attached to a previously undocumented host plant belonging to the genus Chamaesaracha in eastern Colorado on July 2017. At one site, L. decemlineata were more abundant on Chamaesaracha sp. than the accepted ancestral host plant, Solanum rostratum (Dunal). While future studies should confirm the ancestral status of the observed L. decemlineata and suitability of Chamaesaracha sp. for completion of development, our observations suggest a need for further characterization of the ancestral host range of L. decemlineata.


The Ability Of Specific-Wavelength Led Lights To Attract Night-Flying Insects, Ryan S. Zemel, David Houghton Feb 2018

The Ability Of Specific-Wavelength Led Lights To Attract Night-Flying Insects, Ryan S. Zemel, David Houghton

The Great Lakes Entomologist

This paper describes a portable collecting light, designed by the authors, that weighs 0.3 kg, is powered by 8 AA batteries, and uses 9 light-emitting diodes (LEDs) to attract night-flying insects. Five different wavelengths of these LED lights, all within the long-wave ultraviolet spectrum, were compared to each other and to a commercially-available 15w fluorescent ultraviolet tube light for their abilities to collect insects over a series of 5 nights in July 2016. There was no difference in order richness, total specimen abundance, or the specimen abundance of most common orders between any of the wavelengths tested. Most LED ...


The Drosophilids Of A Pristine Old-Growth Northern Hardwood Forest, Thomas Werner Feb 2018

The Drosophilids Of A Pristine Old-Growth Northern Hardwood Forest, Thomas Werner

The Great Lakes Entomologist

The current study summarizes the results of a species inventory survey for drosophilid flies (family Drosophilidae, order Diptera) in a primeval forest in northern Michigan. The two main goals of the investigation were to list the species inhabiting the Huron Mountain Club and to collect live specimens for the illustrations in the book "Drosophilids of the Midwest and Northeast". From 2014 to 2016, I found 22 drosophilid species, which belong to the two subfamilies Steganinae and Drosophilinae. Future long-term studies are planned to test how the drosophilid populations respond to climate change.

Insect (Arthropoda: Insecta) Composition In The Diet Of Ornate Box Turtles (Terrapene Ornata Ornata) In Two Western Illinois Sand Prairies, With A New State Record For Cyclocephala (Coleoptera: Scarabaeidae), Reese J. Worthington, E. R. Sievers, D. B. Ligon, P. K. Lago Feb 2018

Insect (Arthropoda: Insecta) Composition In The Diet Of Ornate Box Turtles (Terrapene Ornata Ornata) In Two Western Illinois Sand Prairies, With A New State Record For Cyclocephala (Coleoptera: Scarabaeidae), Reese J. Worthington, E. R. Sievers, D. B. Ligon, P. K. Lago

The Great Lakes Entomologist

A study of fecal samples collected over a two-year period from juvenile ornate box turtles (Terrapene ornata ornata Agassiz) revealed diets consisting of six orders of insects representing 19 families. Turtles were reared in captivity from eggs harvested from local, wild populations, and released at two remnant prairies. Identifiable insect fragments were found in 94% of samples in 2013 (n=33) and 96% in 2014 (n=25). Frequency of occurrence of insects in turtle feces is similar to results reported in previous studies of midwestern Terrapene species. A comparison of insect composition presented no significant difference between release sites. There ...


The Effects Of Soil Moisture, Soil Texture, And Host Orientation On The Ability Of Heterorhabditis Bacteriophora (Rhabditida: Heterorhabditidae) To Infect Galleria Mellonella (Lepidoptera: Pyralidae), Suzanne M. Hartley, John R. Wallace Feb 2018

The Effects Of Soil Moisture, Soil Texture, And Host Orientation On The Ability Of Heterorhabditis Bacteriophora (Rhabditida: Heterorhabditidae) To Infect Galleria Mellonella (Lepidoptera: Pyralidae), Suzanne M. Hartley, John R. Wallace

The Great Lakes Entomologist

Abstract

Entomopathogenic nematodes (EPN) demonstrate potential as a biological control for soil dwelling insects. However, edaphic factors, such as soil moisture and texture impact the efficacy of EPN on a host. The objectives were to examine the effects of soil texture and moisture on 1) the infection rate of Galleria mellonella L. by EPN and; 2) the ability of H. bacteriophora (Poinar) to move through the soil to find a host at different orientations. Soil textures consisted of sand, a sand/silt/peat mixture, and a silt/peat mixture at 50% and 100% moisture. A general linear model was used ...

New Species Records For Wisconsin False Click Beetles (Coleoptera: Eucnemidae),, Robert L. Otto, Daniel K. Young Feb 2018

New Species Records For Wisconsin False Click Beetles (Coleoptera: Eucnemidae),, Robert L. Otto, Daniel K. Young

The Great Lakes Entomologist

In Wisconsin, Microrhagus opacus, Euryptychus ulkei and Fornax bicolor are recorded for the first time. Records for these three species are based on nine specimens, most of which were taken since 2008. Two specimens of M. opacus taken from a Grant County Malaise trap in the late 1970’s as part of a statewide gypsy moth parasitoid recovery project, were previously identified as Microrhagus audax. Most of the specimens reported herein were taken late in the collecting season, primarily during August. A checklist of the 20 genera and 41 species of Wisconsin Eucnemidae is also included.

The Bee, A Natural History, By Noah Wilson-Rich (2014, Princeton University Press. Isbn: 9780691161358. Us$27.95), Gard W. Otis Dr.

The Great Lakes Entomologist

(excerpt)

Upon receiving “The Bee, A Natural History”, by Noah Wilson Rich, I was drawn in by the title and the beautiful rust and grey front cover featuring a nearly 3-D photo of a honey bee. I immediately felt twinges of excitement—this is the book I have always wanted to have available for my university course, Apiculture and Honey Bee Biology—and disappointment—I did not write it! The “bee”— singular—accompanied by the high-resolution photo, suggested that this book focused on the world’s best understood insect that my course is centered around, Apis mellifera.


First Record Of The Arid-Land Termite, Reticulitermes Tibialis Banks, In Wisconsin, Rachel A. Arango Feb 2018

First Record Of The Arid-Land Termite, Reticulitermes Tibialis Banks, In Wisconsin, Rachel A. Arango

The Great Lakes Entomologist

During a survey of termites in Wisconsin, one colony was found from a different habitat than the remaining populations. This observation led to further genetic testing which resulted in a determination of Reticulitermes tibialis Banks. This is the first record of a termite species other than Reticulitermes flavipes (Kollar) to be established in the state.


Regional Caddisfly (Trichoptera) Indicator Species For Mid-Order Michigan And Minnesota Streams, David C. Houghton Feb 2018

Regional Caddisfly (Trichoptera) Indicator Species For Mid-Order Michigan And Minnesota Streams, David C. Houghton

The Great Lakes Entomologist

Nearly 150,000 caddisfly specimens representing 238 species were analyzed from 166 5–15m wide streams within Michigan and Minnesota to deter- mine the characteristic indicator species of 5 previously-established regions of caddisfly biological diversity. Based on a combination of relative frequency and abundance, 35 of these species indicated a particular region or regions. Indicator species in forested regions constituted a balance of trophic functional groups, whereas indicator species from agricultural regions were dominated by filtering collectors. While it was difficult to determine if species were indicating natural habitat type or differences in anthropogenic disturbance, establishing indicator species now will ...


How Did E. M. Walker Measure The Length Of The Labium Of Nymphs Of Aeshna And Rhionaeschna (Odonata: Aeshnidae)?, Robert B. Dubois, Kenneth J. Tennessen Feb 2018

How Did E. M. Walker Measure The Length Of The Labium Of Nymphs Of Aeshna And Rhionaeschna (Odonata: Aeshnidae)?, Robert B. Dubois, Kenneth J. Tennessen

The Great Lakes Entomologist

The exhaustive studies of nymphs of Aeshna Fabricius and Rhionaeschna Förster by E. M. Walker (1912-1958) have long guided the taxonomy of these groups and formed the basis for keys still in use today. However, uncertainty about how he measured the length of the labium, including the varied terminology he used over the duration of his career concerning this structure, has led to confusion about application of his taxonomic recommendations. We recalculated ratios of the maximum width/length [W(max)/L] by measuring the illustration dimensions of folded labia and prementums in publications throughout his career and compared these data ...


Phenological Attributes And Phylogenetic Relationships Of Rhagoletis Juniperina Marcovitch (Diptera: Tephritidae) In The Great Lakes Region, Megan Frayer, Daniel Hulbert, Serdar Satar, James J. Smith Feb 2018

Phenological Attributes And Phylogenetic Relationships Of Rhagoletis Juniperina Marcovitch (Diptera: Tephritidae) In The Great Lakes Region, Megan Frayer, Daniel Hulbert, Serdar Satar, James J. Smith

The Great Lakes Entomologist

Rhagoletis juniperina Marcovitch (Diptera: Tephritidae) infests Eastern Red Cedar (Juniperus virginiana L.) and other North American junipers. While several Rhagoletis species are of interest as orchard crop pests (apple maggot, blueberry maggot, cherry fruit fly) and as models for studying speciation (R. pomonella Walsh species group), R. juniperina is of interest because it may tie together evolutionarily the Nearctic and Palearctic Rhagoletis fauna. One goal of this study was to test two competing hypotheses first proposed by Bush (1966): i) that R. juniperina is more closely related to the Nearctic dogwood- infesting R. tabellaria (Fitch), to which it is morphologically ...


Comparison Of Different Trap Colors And Types For Capturing Adult Agrilus (Coleoptera: Buprestidae) And Other Buprestids, Toby R. Petrice, Robert A. Haack Feb 2018

Comparison Of Different Trap Colors And Types For Capturing Adult Agrilus (Coleoptera: Buprestidae) And Other Buprestids, Toby R. Petrice, Robert A. Haack

The Great Lakes Entomologist

Numerous research studies have focused on the development of effective traps for surveying and monitoring for emerald ash borer, Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), since it was discovered in North America. However, little attention has been placed on developing effective traps for monitoring and surveying other Agrilus and Buprestidae. In 2009–2011, we conducted several studies to test the attractiveness of different trap colors and types of sticky traps to Agrilus and other Buprestidae. We found green (peak reflectance: 530–536 nm, 57.6%) sticky traps that consisted of custom colored corrugated plastic, and were coated with insect trapping glue ...


Survival And Phenology Of Agrilus Planipennis (Coleoptera: Buprestidae) Reared On A Newly Developed Artificial Diet Free Of Host Material, Melody A. Keena, Hannah Nadel, Juli Gould Feb 2018

Survival And Phenology Of Agrilus Planipennis (Coleoptera: Buprestidae) Reared On A Newly Developed Artificial Diet Free Of Host Material, Melody A. Keena, Hannah Nadel, Juli Gould

The Great Lakes Entomologist

The final phase in the development of an artificial diet that contains no ash host material and the phenology of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Bupresidae) on that diet are documented. A diet containing powdered ash phloem exists, but host material introduces potential variability and contamination, and the cost and effort needed to collect and process it can be high. The post-embryonic development of A. planipennis was evaluated on four artificial diets lacking host material, and effects of variations in diet layer thickness and moisture content were also investigated. The best diet and rearing method resulted in ...


Nocturnal Flight Periodicity Of The Caddisflies (Trichoptera) In Forest And Meadow Habitats Of A First Order Michigan Stream, Kiralyn Brakel, Lydia R. Wassink, David C. Houghton Feb 2018

Nocturnal Flight Periodicity Of The Caddisflies (Trichoptera) In Forest And Meadow Habitats Of A First Order Michigan Stream, Kiralyn Brakel, Lydia R. Wassink, David C. Houghton

The Great Lakes Entomologist

Using ultraviolet light traps, over 5000 caddisfly specimens were collected from a forest and a meadow habitat of Fairbanks Creek in northern Lower Michigan. Samples were collected every 15 minutes, interspersed with 15 minutes of no sampling, from sunset to sunrise during 5 nights from late June to mid-July 2014. Despite having fundamentally different caddisfly assemblages dominated by different species, mean specimen abundance and mean species richness in both habitats exhibited similar trends: peaking between 22:30 and 23:00, decreasing until 02:00 or 02:30, increasing again slightly during the later morning periods, and then decreasing to near ...

First Record Of The Enicocephalidae (Heteroptera) In Michigan And Ohio, Daniel R. Swanson

The Great Lakes Entomologist

The unique-headed bug, Systelloderes biceps (Say), is reported from Michigan and Ohio, resulting in two new state records for the family Enicocephalidae.


Movement Patterns Of Carabid Beetles Between Heterogenous Crop And Noncrop Habitats, Heather Russon, J. Megan Woltz Feb 2018

Movement Patterns Of Carabid Beetles Between Heterogenous Crop And Noncrop Habitats, Heather Russon, J. Megan Woltz

The Great Lakes Entomologist

Habitats adjacent to crop fields can increase natural enemy populations by providing additional food, shelter and overwintering sites. While many studies have focused on the role of non-crop borders for supporting natural enemies, here we investigate the influence of adjacent crop habitats as well. We monitored the movement of carabid beetles (Coleoptera: Carabidae) between wheat fields and adjacent crop and non-crop habitats using bi-directional pitfall traps. We found greater movement of carabids from corn into wheat fields than from forest and soybean, with intermediate levels of movement from roadside vegetation. Additionally, significantly more carabids were captured moving into corn from ...


Stink Bugs (Hemiptera: Heteroptera: Pentatomidae) Of Minnesota: An Annotated Checklist And New State Records, Robert L. Koch, David A. Rider, Paul P. Tinerella, Walter A. Rich Feb 2018

Stink Bugs (Hemiptera: Heteroptera: Pentatomidae) Of Minnesota: An Annotated Checklist And New State Records, Robert L. Koch, David A. Rider, Paul P. Tinerella, Walter A. Rich

The Great Lakes Entomologist

Pentatomidae have been relatively poorly documented in Minnesota. Based on literature and museum records, an annotated checklist of the Pentatomidae of Minnesota was created. State-level and county-level records for Minnesota and the distribution of each species in North America are provided. Fifty-one species of Pentatomidae (12 Asopinae, 37 Pentatominae, and 2 Podopinae) are recorded for Minnesota. Of this total, 15 species are newly recorded for the state. Knowledge of the fauna of Pentatomidae in Minnesota will be important for providing baseline data for monitoring of potential shifts in the fauna resulting from the invasions of exotic Pentatomidae. Furthermore, a list ...


Northern-Most North American Flower Visitation Records Of The Introduced Flower Fly, Syritta Flaviventris (Diptera: Syrphidae) And Comparisons With Sympatric Species, Syritta Pipiens, C. Sheena Sidhu, D. J. Biddinger Feb 2018

Northern-Most North American Flower Visitation Records Of The Introduced Flower Fly, Syritta Flaviventris (Diptera: Syrphidae) And Comparisons With Sympatric Species, Syritta Pipiens, C. Sheena Sidhu, D. J. Biddinger

The Great Lakes Entomologist

We report for the first time the syrphid fly, Syritta flaviventris (Macquart), collected in Lancaster County, Pennsylvania, as the northern-most record for this introduced Mediterranean species. In total, 3 male specimens and 1 female specimen were net collected on three flower species (Verbena hastata, Eryngium yuccifolium and Asclepias incarnata), at a single site of 11 monitored farm sites in southern Pennsylvania. Floral records for the similar introduced sibling species, Syritta pipiens (L.), are presented as well. Passive monitoring with colored pan traps used to monitor bee populations at these sites was not effective in collecting either species of Syritta. Our ...


A Comparison Of The Effectiveness Of Pitfall Traps And Winkler Litter Samples For Characterization Of Terrestrial Ant (Formicidae) Communities In Temperate Savannas, Sean B. Menke, Nicole Vachter Feb 2018

A Comparison Of The Effectiveness Of Pitfall Traps And Winkler Litter Samples For Characterization Of Terrestrial Ant (Formicidae) Communities In Temperate Savannas, Sean B. Menke, Nicole Vachter

The Great Lakes Entomologist

Relatively few studies in temperate environments have compared pitfall traps and Winkler litter samples, two of the most commonly used ant (Formicidae) sampling protocols. Most of the comparative work has been performed in tropical and subtropical environments. Temperate studies have primarily taken place in forested environments. Our study focuses on the relative efficiency of these two methods in temperate oak savannas, the major ecotone connecting grasslands and deciduous forest in the Midwest. These environments are often maintained by fire and mechanical brush removal, which tends to decrease the amount of available leaf litter. We sampled 21 sites, varying in age ...


Establishment, Impacts, And Current Range Of Spotted Knapweed (Centaurea Stoebe Ssp. Micranthos) Biological Control Insects In Michigan, B. D. Carson, C. A. Bahlai, D. A. Landis Feb 2018

Establishment, Impacts, And Current Range Of Spotted Knapweed (Centaurea Stoebe Ssp. Micranthos) Biological Control Insects In Michigan, B. D. Carson, C. A. Bahlai, D. A. Landis

The Great Lakes Entomologist

Centaurea stoebe L. ssp. micranthos (Gugler) Hayek (spotted knapweed) is an invasive plant that has been the target of classical biological control in North America for more than four decades. Work in the western U.S. and Canada has shown the seedhead-feeding weevils Larinus minutus Gyllenhal and Larinus obtusus Gyllenhal (Coleoptera: Curculionidae) and the root-boring weevil Cyphocleonus achates (Fahraeus) (Coleoptera: Curculionidae) to be the most effective C. stoebe control agents. These three weevils have recently been introduced into the eastern U.S., including sites in Michigan in 2007 and 2009. In 2010, we made additional releases at six sites in ...


Butterflies (Lepidoptera) On Hill Prairies Of Allamakee County, Iowa: A Comparison Of The Late 1980s With 2013, Nicole M. Powers, Kirk J. Larsen Feb 2018

Butterflies (Lepidoptera) On Hill Prairies Of Allamakee County, Iowa: A Comparison Of The Late 1980s With 2013, Nicole M. Powers, Kirk J. Larsen

The Great Lakes Entomologist

In the late 1980s, several hundred butterflies were collected by John Nehnevaj from hill prairies and a fen in Allamakee County, Iowa. Nehnevaj’s collection included 69 species, 14 of which are currently listed in Iowa as species of greatest conservation need (SGCN). The goal of this study was to revisit sites surveyed in the 1980s and survey three additional sites to compare the species present in 2013 to the species found by Nehnevaj. A primary objective was to document the presence of rare prairie specialist butterflies (Lepidoptera), specifically the ottoe skipper (Hesperia ottoe W.H. Edwards; Hesperiidae), which was ...


Differences In Thermal Tolerance Between Two Thermally Isolated And Genetically Indistinct Populations Of Paragnetina Media (Walker) (Plecoptera: Perlodidae), Bridget C. O'Leary, David C. Houghton, Jeffrey Van Zant Feb 2018

Differences In Thermal Tolerance Between Two Thermally Isolated And Genetically Indistinct Populations Of Paragnetina Media (Walker) (Plecoptera: Perlodidae), Bridget C. O'Leary, David C. Houghton, Jeffrey Van Zant

The Great Lakes Entomologist

The critical thermal maximum (CTM) of Paragnetina media (Walker) (Plecoptera: Perlodidae) was studied at two sites of the Big Sable River in northwestern Lower Michigan during summer 2013. The sites were separated by ~8 km and differed in temperature by ~1°C in the early spring to ~5°C in mid-summer. Individual P. media specimens from the warm site had consistently higher CTM when acclimated to the mean temperature of the two sites for 3 days prior to experimental trials during May, June, and July. When acclimated for an additional 3 days to a higher or lower temperature, this thermal ...

(excerpt)

Those of you who know me may think I’ve always been a “beetle guy” but growing up in southwestern Michigan and loving to trout fish, my first real insect infatuation was with aquatic insects. It was, in fact, not until the summer of my junior/senior year at Michigan State University that I was re- ally introduced to beetles – by a Ph.D. student for whom I worked as a student hourly (on cucumber pollination and honey bees)!

(excerpt)

My early interests in entomology were augmented with How to Know the Beetles by H.E. Jacques (1951), and the Peterson Guide - A Field Guide to the Beetles of North America by Richard E. White (1983). In addition, Dillon and Dillon’s (1972) A Manual of Common Beetles of Eastern North America was extremely helpful to a beginning collector trying to identify his catches.

Ten Bee Species New To Green Roofs In The Chicago Area, Kelly Ksiazek, Rebecca Tonietto, John S. Ascher Feb 2018

Ten Bee Species New To Green Roofs In The Chicago Area, Kelly Ksiazek, Rebecca Tonietto, John S. Ascher

The Great Lakes Entomologist

Green roofs increasingly provide habitat for many insects in urban environments. Pollinators such as bees may utilize foraging and nesting resources provided by green roofs but few studies have documented which species occur in these novel habitats. This study identified bees from 26 species, 11 genera and 5 families collected from 7 green roofs using pan trapping methods over 2 years. Ten of these species have not previously been recorded on green roofs in the Chicago region. Although the majority of bee species collected were solitary, soil-nesting, and native to Illinois, the proportion of exotic species was high compared to ...
