Additions And Corrections To The Stoneflies (Plecoptera) Of Iowa, U.S.A., Dennis P. Heimdal, Michael W. Birmingham

The Great Lakes Entomologist

(exerpt)

Until recently, Iowa’s stonefly fauna was poorly documented. Heimdal et al. (2004) published a comprehensive report on stonefly distributions within the state, reporting seven families and 43 species. Five species, Allocapnia pygmaea (Burmeister) (Capiniidae), Leuctra tenuis (Pictet) (Leuctridae), Amphinemura linda (Ricker) (Nemouridae), Nemoura trispinosa Claassen (Nemouridae), and Soyedina vallicularia (Wu) (Nemouridae), were recommended for state protection because of their limited distribution within Iowa. Four species, Amphinemura delosa (Ricker), Isogenoides doratus (Frison) (Perlodidae), I. krumholzi (Ricker), and I. varians (Walsh), had limited distributions, but were not listed because their observed habitat preferences appeared common or were difficult to sample and …

First Record Of Harpalus Ochropus Kirby (Coleoptera: Carabidae) From Minnesota And The Conterminous United States, Foster Forbes Purrington, Richard M. Maxey

The Great Lakes Entomologist

(excerpt)

The epigeal ground beetle Harpalus ochropus Kirby (Coleoptera: Carabidae) has been reported from Alaska and across Canada from British Columbia into Quebec (Bousquet and Larochelle 1993). It is local and rarely collected. Gandhi et al. (2005) surveyed for carabids extensively for several years along the Gunflint Trail and adjacent Boundary Waters Canoe Area in northeastern Minnesota.

A Friend Unmasked: Notes On Chauliognathus Pensylvanicus (Coleoptera: Cantharidae) And The Nature Of Natural History, Andrew H. Williams

The Great Lakes Entomologist

Data from field observations from 1992 through 2006 and from museum specimens of adult Chauliognathus pensylvanicus (DeGeer) from Wisconsin are presented here, with information from the literature. Beetles were found using flowers of 183 species in 29 families growing outside cultivation in Wisconsin and in every Wisconsin county. All evidence supports the characterization of C. pensylvanicus as a prairie insect that also lives in other, early successional plant communities.

Patch-Scale Movement Dynamics In The Iowa Grassland Butterflies Speyeria Cybele And Megisto Cymela (Lepidoptera: Nymphalidae), David Courard-Hauri, Ashley A. Wick, Lindsey K. Kneubuhler, Keith S. Summerville

The Great Lakes Entomologist

An understanding of the movement dynamics of invertebrates can be critical to their conservation, especially when managing relatively small, isolated habitats. Most studies of butterfly movement have focused on metapopulation dynamics at relatively large spatial scales, and the results from these studies may not translate well for patchy populations within a single nature preserve. In this work we use individual mark and recapture (IMR) methods to follow the movements of two species of butterfly, Megisto cymela (Cramer) and Speyeria cybele F. (Lepidoptera: Nymphalidae) within a 240 hectare forest and grassland preserve in central Iowa, USA. Significant redistribution was seen in …

Anoplophora Glabripennis Within-Tree Distribution, Seasonal Development, And Host Suitability In China And Chicago, Robert A. Haack, Leah S. Bauer, Rui-Tong Gao, Joseph J. Mccarthy, Deborah L. Miller, Toby R. Petrice, Therese M. Poland

The Great Lakes Entomologist

Established populations of the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), were first reported in the United States in New York in 1996, Illinois in 1998, and New Jersey in 2002. A federal quarantine and an eradication program were implemented in 1997, involving tree surveys and removal of infested trees. We recorded the number of A. glabripennis life stages found at several locations along the main trunk and major branches of naturally infested trees in China (species of Populus, Salix, and Ulmus) and Chicago, Illinois (species of Acer, Fraxinus, and Ulmus) during 1999 to 2002. Typically, …

Variation In Detecting Schinia Indiana And Schinia Lucens (Lepidoptera: Noctuidae) In Wisconsin, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

Schinia indiana (Smith) and Schinia lucens (Morrison) (Lepidoptera: Noctuidae) are diurnal moths and are well camouflaged when perched on flowers of their larval food plants: Phlox pilosa L. (Polemoniaceae) and Amorpha(Fabaceae), respectively. We recorded 264 S. indiana in diurnal surveys of 28 units of 15 sites in Jackson County, WI, and 25 units of 5 sites in Burnett County, WI, from 23 May (2006) to 15 June (1994). The longest flight periods in single years were 21 days in 1994 and 17 days in 2006. Abundance of individuals was significantly greater when phlox flowering was prepeak and peak, compared …

Compensatory Feeding And Growth Responses Of Papilio Glaucus (Lepidoptera: Papilionidae) Larvae Reared In Darkness., Jennifer Muehlhaus, J. Mark Scriber

The Great Lakes Entomologist

The goal was to determine the potential impact of photoperiod on feeding behavior and larval growth rates. Larvae from six different families of the eastern swallowtail butterfly, Papilio glaucus L. (Lepidoptera: Papilionidae) were placed into 3 different photoperiod regimes (long days at 18:6 h, short days at 12:12 h, and total darkness at 0:24 h, all at 27°C) as neonate first instars and reared to pupation. The initial 11 days reflected very slow growth of the larvae in darkness (only half the weight of the long day larvae). No differences in survival at 4 days or 11 days or until …

Variation In Diel Activity Of Ground Beetles (Coleoptera: Carabidae) Associated With A Soybean Field And Coal Mine Remnant, Jason E. Willand, Kenneth W. Mccravy

The Great Lakes Entomologist

Diel activities of carabids (Coleoptera: Carabidae) associated with a coal mine remnant and surrounding soybean field were studied in west-central Illinois from June through October 2002. A total of 1,402 carabids, representing 29 species and 17 genera, were collected using pitfall traps. Poecilus chalcites (Say) demonstrated roughly equal diurnal and nocturnal activity in June, but greater diurnal activity thereafter. Pterostichus permundus (Say), Cyclotrachelus seximpressus (LeConte), Amara obesa (Say), and Scarites quadriceps Chaudoir showed significant nocturnal activity. Associations between habitat and diel activity were found for three species: P. chalcites associated with the remnant and edge habitats showed greater diurnal activity …

Diversity Of Cicadellidae And Cercopidae (Hemiptera) On Sand Prairies Of Newaygo County, Michigan, James P. Dunn, Holly A. Hereau, Adam J. Klomp

The Great Lakes Entomologist

Sand prairies in the Great Lakes region occur as small sites dispersed through- out a heavily disturbed landscape. These unique natural areas are dominated by dry prairie grasses and are inhabited by a diversity of insects of which Cicadellidae and Cercopidae are among the most diverse groups. Their species compositions have been implicated as being potential indicators of ecological quality that could be used to rank the quality of prairie vegetation. In Newaygo Co., Michigan, 12 sand prairies were surveyed for Cicadellidae and Cercopidae and these data were then used to estimate species diversity for each site by the Simpson’s …

Oviposition And Development Of Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae) On Hosts And Potential Hosts In No-Choice Bioassays, Andrea C. Anulewicz, Deborah G. Mccullough, Deborah L. Miller

The Great Lakes Entomologist

Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Bupres- tidae) is an invasive phloem-feeding pest native to Asia. It was first identified in North America in 2002 and has killed millions of ash (Fraxinus spp.) trees in southeast Michigan and Essex County, Ontario. Since then, additional populations have been discovered across Michigan and in areas of Ohio, Indiana, Illinois, Maryland, Pennsylvania and West Virginia. In Asia, A. planipennis reportedly colonizes other genera, including species of Juglans, Pterocarya and Ulmus. In North America, attacks on non-ash species have not been observed but there is concern about host switching as …

A Field Guide To The Tiger Beetles Of The United States And Canada: Identification, Natural History, And Distribution Of The Cicindelidae. D. L. Pearson, D. B. Knisley, And D. J. Kazilek. 2006. Oxford University Press, 227 Pp., Soft Cover., Kamal J.K. Gandhi

The Great Lakes Entomologist

(excerpt)

Tiger Beetles are a favorite among insect collectors because of their beauty, diversity, and fascinating adult and larval behavior. Cicindelophiles, or tiger beetle enthusiasts, have been blessed during the past decade as a number of regional field-guides have been published on these insects (Knisley and Schultz 1997, Leonard and Bell 1999, Acorn 2001, Pearson and Vogler 2001, Choate 2003). However, missing from the shelf was a book about the synthesis of tiger beetles of America north of Mexico, and this book fills exactly that much coveted empty space on the entomologist’s book-shelf.

Early-Season Phenology And Temporal Dynamics Of The Common Asparagus Beetle, Crioceris Asparagi (Coleoptera: Chrysomelidae), In Southern Minnesota, Suzanne J. Wold-Burkness, P. C. Bolin, W. D. Hutchison

The Great Lakes Entomologist

During the years 1991-1994, studies were conducted to determine the early-season phenology and temporal dynamics of Crioceris asparagi (L.) (Co- leoptera: Chrysomelidae) in southern Minnesota asparagus. To document the early-season phenology, asparagus plots were sampled for egg, larval, and adult stages of C. asparagi during the months of May and June. Temporal dynamics of C. asparagi were determined by measuring the diurnal activity of adults and sampling asparagus plots at specific times (7 am, 9 am, 11 am, 1 pm, 3 pm and 5 pm) throughout May and June. We first detected C. asparagi adults in early May and they …

Congener Host Selection By The Pre-Dispersal Seed Predator, Apion Rostrum (Coleoptera: Apionidae), Chris E. Petersen, Weien Wang

The Great Lakes Entomologist

Apion rostrum Say (Coleoptera: Apionidae) is the major seed predator of the wild indigo congeners, Baptisia alba and B. bracteata in the Russell Kirt Tallgrass Prairie, a reconstructed prairie located at College of DuPage, Illinois. This study, conducted during 2006, investigated factors attracting A. rostrum to each congener. The two Baptisia differ in developmental period, stature, and patterns of dispersion. B. bracteata flowers and initiates pods usually along a single raceme during late spring, and is a shorter plant that grows in clusters. In contrast, B. alba flowers and initiates pods beginning a month after B. bracteata, produces a …

Comparative Biology And Life Tables Of Trichogramma Brassicae And Trichogramma Cacoeciae With Ephestia Kuehniella As Host At Three Constant Temperatures, Nihal Ozder

The Great Lakes Entomologist

Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) have been successfully utilized for biocontrol of several lepidopteran pests world-wide. The age specific fecundity of Trichogramma brassicae Bezdenko and Trichogramma cacoeciae Marchal using Ephestia kuehniell a Zeller (Lepidoptera: Pyralidae) as host were determined at 20, 26, and 30 °C and 60-70 % R.H. in the laboratory. Both T. cacoeciae and T. brassicae demonstrate high parasitism ability and intrinsic rates of increase on E. kuehniella and had a similar response to increasing temperature.

Discovery Of Sirex Noctilio (Hymenoptera: Siricidae) In Ontario, Canada, Peter De Groot, Kathyrn Nystrom, Taylor Scarr

The Great Lakes Entomologist

A sirex woodwasp, commonly called “sirex woodwasp” or the “European woodwasp” Sirex noctilio (Fabricius) (Hymenoptera: Siricidae), is a high-risk alien invasive forest insect for North America. In September 2004, this insect was trapped in the field in New York, identified in February 2005 and confirmed as established in July 2005 – the first record of such for North America. The close proximity of the original and subsequent discoveries of S. noctilio in New York prompted a rapid response survey for this insect in adjacent areas in Ontario, Canada. This report records the first discoveries of this wood wasp in Canada …

Seasonal Abundance; Damage; And Comparison Of Different Heights, Orientations, And Directions Of Yellow Sticky Traps For Sampling Of Liriomyza Trifolii (Diptera: Agromyzidae) In Cotton, Ibrahim Gencsoylu

The Great Lakes Entomologist

This study was done to determine the optimum height, orientation, and direction of yellow sticky traps for sampling of Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) in cotton fields. Leaf infestation rates for the whole plants, as well as for each of three plant regions, and number of mines per infested leaf were also determined. Traps were placed at 25 cm above the plant canopy and 30 cm above the ground at two orientations (horizontal and vertical) and two directions (east-to-west and north-to-south) for each height and orientation in Aydin province, Turkey. Horizontally oriented traps captured more flies than vertically oriented traps. …

Effect Of The Cardenolide Digitoxin On Performance Of Gypsy Moth (Lymantria Dispar) (Lepidoptera: Lymantriidae) Caterpillars, David N. Karowe, Victoria Golston

The Great Lakes Entomologist

Despite the central role of cardenolides in the classic milkweed-monarch- predator chemically-mediated multiple trophic level interaction, very few studies have actually demonstrated that cardenolides protect host plants against herbivores. We tested the hypothesis that cardenolides are an effective chemical defense against generalist insect herbivores by feeding fifth instar gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), larvae artificial diets containing low and high levels of digitoxin, a cardenolide found in leaves of purple foxglove,Digitalis purpurea L. (Scrophulariaceae). Relative to performance of larvae fed the control diet, consumption rate, conversion efficiency, and growth rate were all reduced by at least 60% …

Efficacy Of Three Insecticides Applied To Bark To Control Agrilus Planipennis (Coleoptera: Buprestidae), Toby R. Petrice, Robert A. Haack

The Great Lakes Entomologist

Emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is a serious exotic pest of ash (Fraxinus) trees in North America. In 2003 and 2004, we tested the efficacy of different insecticides sprayed on the bark of cut ash logs for killing emerging EAB adults. Logs (means: length = 30 cm; diam. = 16 cm) were cut from infested ash trees and treated prior to adult emergence. In 2003, we applied imidacloprid at 2 times its label rate to logs 5 days before adults began emerging from logs stored indoors. No adults successfully emerged from the imidacloprid treated logs, while …

Gerromorpha (Hemiptera: Heteroptera) In Southern Illinois: Species Assemblages And Habitats, Steven J. Taylor, J. E. Mcpherson

The Great Lakes Entomologist

Gerromorphan species assemblages in southern Illinois were studied at 86 sites representing eleven habitat types (pond, lake, swamp, temporary pool, large river, small river, muddy eutrophic permanent stream, clear rocky permanent stream, clear rocky temporary stream, roadside ditch, and spring) from mid-May 1988 through late July 1991. Assemblages varied in size and composition, with the most diverse found in clear rocky permanent streams. Phenograms tended to cluster major habitat types (e.g., ponds, lakes) based on taxon presence/absence and to cluster the more commonly co-occuring species based on their presence/absence at collection sites. These phenograms indicated the presence of natural guilds …

Khan, Abhishek Kumar, Fei Li, Vincent Lombard, Subba Reddy Palli, June-Sun Yoon

Entomology Faculty Publications

The Colorado potato beetle is one of the most challenging agricultural pests to manage. It has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable climates during its global invasion, and, notably, to rapidly evolve insecticide resistance. To examine evidence of rapid evolutionary change, and to understand the genetic basis of herbivory and insecticide resistance, we tested for structural and functional genomic changes relative to other arthropod species using genome sequencing, transcriptomics, and community annotation. Two factors that might facilitate rapid evolutionary change include transposable elements, which comprise at least 17% of the genome and …

Long-Term Population Monitoring Of The Karner Blue (Lepidoptera: Lycaenidae) In Wisconsin, 1990-2004, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

We monitored Wisconsin populations of the Karner blue (Lycaeides melissa samuelis Nabokov, Lepidoptera: Lycaenidae) during 1990-2004. We surveyed consecutive spring and summer broods in two contiguous central Wisconsin counties (Jackson, Wood), starting with three sites in summer 1990 and expanding to 14 sites by summer 1996 (“constant-site monitoring”). In northwestern Wisconsin (Burnett County), we started constant-site monitoring of consecutive summer broods with 11 sites in 1991, expanding to 15 sites by 1998. Population indices (Karner blue individuals per km on peak survey per site per brood) from constant sites were positively and significantly correlated with comparable indices for the …

Spatial Synchrony In Wisconsin Karner Blue (Lepidoptera: Lycaenidae) Populations, Scott R. Swengel, Ann B. Swengel

The Great Lakes Entomologist

We analyzed geographic patterns of Karner blue (Lycaeides melissa samuelis Nabokov, Lepidoptera: Lycaenidae) population fluctuations in summer broods in central and northwestern Wisconsin and spring+summer broods in central Wisconsin. We removed possible effects of population trends by analyzing residuals from a regression of each site’s population index vs. year. We then calculated correlation coefficients (r) of these residuals for all site-pairs separately for 1992- 2005 (26 sites, N = 325 site-pairs), 1995-2005 (21 sites, N = 210), and 1998-2005 (14 sites, N = 91). We analyzed patterns in these r values relative to distance between sites using correlations vs. distance …

Diagnostic Efficacy Of Morphological Characters Of Larval Tramea Lacerata Hagen And Tramea Onusta Hagen (Odonata: Libellulidae) In The Prairie Region Of Missouri, Brett H. P Landwer, Robert W. Sites

The Great Lakes Entomologist

Distinguishing among species of larvae of the dragonfly genus Tramea historically has been problematic, largely due to conflicting characterizations of the larvae of T. lacerata Hagen and T. onusta Hagen (Odonata: Libellulidae) in the literature. The various systematic treatments usually focused on relative lengths of morphological characters to distinguish the species, but often contradicted one another and themselves as to what the diagnostic values actually were. We traced much of the confusion back to errors in the original larval description of T. onusta. We used morphometric analyses to determine the efficacy of previously published characterizations to distinguish between the …
