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 …

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 …
