Movement Patterns Of Carabid Beetles Between Heterogenous Crop And Noncrop Habitats, 2018 Kalamazoo College
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, 2018 University of Minnesota
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
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 …
A Comparison Of The Effectiveness Of Pitfall Traps And Winkler Litter Samples For Characterization Of Terrestrial Ant (Formicidae) Communities In Temperate Savannas, 2018 Lake Forest College
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
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 Michigan, monitoring …

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 thought …

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 disadvantage disappeared. …

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)!

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, 2018 Northwestern University
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 …
Improvement Of Pheromone Trapping In Low Density Populations Of Choristoneura Pinus Pinus (Lepidoptera: Tortricidae), 2018 Natural Resources Canada
Improvement Of Pheromone Trapping In Low Density Populations Of Choristoneura Pinus Pinus (Lepidoptera: Tortricidae), J. G. Fidgen, P. Silk, K. L. Ryall, T. Scarr
The Great Lakes Entomologist
Pheromone baited bucket traps (e.g., Multipher) are popular as a monitoring tool for the jack pine budworm, Choristoneura pinus pinus Freeman (Lepidoptera: Tortricidae), in Canada. However, there is no evidence to support their use when budworm populations are low. We therefore evaluated the capture rate of bucket traps at two placement heights (2 vs 6 m) in two jack pine forests in 2011, having low (≤5 fifth instars per mfoliated branch length) budworm populations. Compared to wing traps (e.g., Pherocon 1C), the trap design used initially to evaluate efficacy of the C. pinus pheromone, bucket traps caught fewer C. pinus …

New Distributional Record For Balcha Indica (Hymenoptera: Eupelmidae) In Eastern West Virginia Discovered During Emerald Ash Borer Parasitoid Recovery Surveys, Tara Spinos, Amy Hill, Rachel Braud, Richard M. Turcotte
The Great Lakes Entomologist
Between 2010 and 2012, approximately 6,300 Spathius agrili Yang (Hymenoptera: Braconidae) and 9,500 Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) parasitoids were released for biological control of the invasive emerald ash borer, Agrilus planipennis Fairmaire, at Cacapon State Park and the Cool Front Development in Morgan County, West Virginia. The invasive beetle was first detected there in 2009, and extensive ash mortality is currently occurring. We conducted parasitoid recovery surveys in 2013 but did not recover either of the released parasitoid species. However, we did rear Balcha indica Mani and Kaul (Hymenoptera: Eupelmidae), which is native to Asia and is a documented …

Additions To The Checklist Of Wisconsin Ground Beetles (Coleoptera: Carabidae), Including The Adventive Harpalus Rubripes (Duftschmid) Among Seven New State Records, Peter W. Messer
The Great Lakes Entomologist
Sixteen species are added to the checklist of Wisconsin Geadephaga. Of these, seven species are reported here as new to Wisconsin. Nine taxa from the list are affected by new information resulting in the removal of six names. The Eurasian beetle Harpalus rubripes was discovered as early as 2009 on annually surveyed beaches along Lake Michigan in southeastern Wisconsin. This discovery greatly extends the species distribution westward from its presence in northeastern North America where it was first recorded in 1981.
Observations On The Biological Control Agents Of The American Plum Borer (Lepidoptera: Pyralidae) In Michigan Cherry And Plum Orchards, 2018 Pennsylvania State University
Observations On The Biological Control Agents Of The American Plum Borer (Lepidoptera: Pyralidae) In Michigan Cherry And Plum Orchards, David J. Biddinger, Timothy W. Leslie
The Great Lakes Entomologist
The American plum borer, Euzophera semifuneralis (Walker) (Lepidoptera: Pyralidae), is an important pest in orchards, yet little is known regarding its biological control. We performed a comprehensive survey of the natural enemy complex contributing to American plum borer control in Michigan plum and cherry orchards, while also exploring the relationship between pest infestation and tree wounding from mechanical harvesting. We scouted 30 orchards with varying degrees of tree wounding to document extent of infestations of American plum borer and another pest, the lesser peach borer, Synanthedon pictipes (Grote and Robinson) (Lepidoptera: Sessiidae). We simultaneously recorded biological control agents, including the …

Wisconsin beetles harboring C. labidomerae were found in dry to wet-mesic, open habitats. A distribution map and comments are presented.
Desirable Host Plant Qualities In Wild Rice (Zizania Palustris) For Infestation By The Rice Worm Apamea Apamiformis (Lepidoptera: Noctuidae), 2018 University of Minnesota
Desirable Host Plant Qualities In Wild Rice (Zizania Palustris) For Infestation By The Rice Worm Apamea Apamiformis (Lepidoptera: Noctuidae), Nathan B. Dahlberg, John Pastor
The Great Lakes Entomologist
The rate at which an insect infests hosts by ovipositioning and/or subsequent growth of larvae often depends on specific desirable host plant qualities. In this study, we measured the infestation rate of wild rice, Zizania palustris, by the wild rice worm, Apamea apamiformis, D. F. Hardwick (Lepidoptera: Noctuidae) and compared it to sediment nitrogen availability, plant biomass, plant density, litter accumulation, and seed carbohydrate and nitrogen concentration. Plant density and litter accumulation had no effect on infestation rates. Infestation rate increased with plant biomass and sediment nitrogen availability. The correlation between infestation rate and sediment nitrogen availability seems …
