Department of Entomology: Faculty Publications

Rice (Oryza sativa L.) is considered one of the most important crops in the world, and the sugarcane borer, Diatraea saccharalis Fabricius (Lepidoptera: Crambidae), is among the key pests damaging the crop in the Americas. The objective of this work was to identify rice genotypes as a source of resistance to D. saccharalis. Rice plants were infested in the greenhouse and subsequently evaluated for damage, larval weight and survival, and stem size. The cultivars “Bonança,” “Caripuna,” “IR 42,” “Canela de Ferro,” “SWA Norte,” “BR IRGA 409,” “Pepita,” “Serra Dourada,” “Araguaia,” “Xingú,” “Tangará,” and “Soberana” showed antibiosis, antixenosis, or …

Coleopteran Communities Associated With Forests Invaded By Emerald Ash Borer, Matthew B. Savage, Lynne K. Rieske

Entomology Faculty Publications

Extensive ash mortality caused by the non-native emerald ash borer alters canopy structure and creates inputs of coarse woody debris as dead and dying ash fall to the forest floor; this affects habitat heterogeneity; resource availability; and exposure to predation and parasitism. As EAB-induced (emerald ash borer-induced) disturbance progresses the native arthropod associates of these forests may be irreversibly altered through loss of habitat; changing abiotic conditions and altered trophic interactions. We documented coleopteran communities associated with EAB-disturbed forests in a one-year study to evaluate the nature of these changes. Arthropods were collected via ethanol-baited traps on five sites with …

Molecular Gut-Content Analysis Reveals High Frequency Of Helicoverpa Zea (Lepidoptera: Noctuidae) Consumption By Orius Insidiosus (Hemiptera: Anthocoridae) In Sweet Corn, Julie A. Peterson, E. C. Burkness, James D. Harwood, W. D. Hutchison

Department of Entomology: Faculty Publications

Management of corn earworm Helicoverpa zea in sweet corn grown for processing can be challenging due to the lack of effective transgenic and chemical control options. However, biological control by generalist predators can provide a significant impact on pests in this cropping system. One of the most ubiquitous predators of H. zea and other lepidopterans is the insidious flower bug, Orius insidiosus. This small hemipteran has been observed as an important mortality agent of H. zea in several cropping systems, but the strength of the trophic connection between these species has not been documented in sweet corn. Molecular gut-content …

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.

Isodontia Elegans Now In Michigan (Hymenoptera: Sphecidae: Sphecinae), Mark F. O'Brien, Julie A. Craves

The Great Lakes Entomologist

Isodontia elegans (Smith) (Hymenoptera: Sphecidae), one of the “grass- carrying wasps,” previously known only from the western U.S., is now reported from southeastern Michigan, and appears to have spread across the eastern half of the United States in a relatively short period.
