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 …

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 …

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 …

Since its initial detection near Montreal, Canada in 1984, the variegated lady beetle Hippodamia variegata (Goeze) (Coleoptera:Coccinellidae) has spread throughout the northeastern United States. In 2005, this immigrant Old World species was detected in Michigan for the first time. Twenty-nine adults were found in soybean fields in 4 counties: Ingham, Gratiot, Kalamazoo, and Saginaw.The first individuals were found in Gratiot County on 22 June 2005; we continued to detect individuals until 18 Aug 2005 (2 individuals collected in Saginaw Co.) when sampling ended. Prior to this study, H. variegata had not been known to prey on the soybean aphid, Aphis …

Effects Of Different Habitats On The Productivity Of The Native Paper Wasp Polistes Fuscatus And The Invasive, Exotic Paper Wasp P. Dominulus (Hymenoptera: Vespidae), George J. Gamboa, Julie A. Austin, Kimberley M. Monnet

The Great Lakes Entomologist

We examined the colony productivities of the native paper wasp, Polistes fuscatus (Fab.),(Hymenoptera: Vespidae), and the invasive, exotic paper wasp, P. dominulus (Christ), in oak forest, oak forest-old field ecotone, and old field habitats at the Oakland University Preserve in Rochester, Michigan from 2003 to 2005. Both species of paper wasps exhibited significant differences in colony productivity among the three habitats. Generally, colonies were the most productive in the old field habitat and the least productive in the oak forest habitat.

Colonies of P. dominulus were significantly more productive than comparable colonies of P. fuscatus in all three habitats. There …

Cyclocephala lurida Bland (Coleoptera: Scarabaeidae) is a dynastine scarab beetle previously unknown from Wisconsin. Two specimens, one male and one female, were found on the University of Wisconsin-Madison campus. A third specimen was recovered from a blacklight trap in southwestern Wisconsin. Although establishment in the state remains open to question, this species is of potential economic concern as larvae are capable of causing significant damage to lawns, turfgrass, and crops.

Notes On Incidence And Biology Of The Predominant Parasitoids Attacking The Cottonwood Leaf Beetle In Minnesota, Alexander P. Kendrick, Kenneth F. Raffa, Steven J. Krauth, Norman E. Woodley

The Great Lakes Entomologist

Populations of the cottonwood leaf beetle, Chrysomela scripta Fabricius (Coleoptera: Chrysomelidae), in Minnesota were examined for the presence of parasitoids over a period of two years. Field samples of larvae and pre-pupae yielded two parasitoids: a tachinid fly, Cleonice setosa (Reinhard), and a pteromalid wasp, Schizonotus sieboldi (Ratzeburg). Incidence of parasitism by the tachinid was substantially higher than in previous reports, with 32.9% of third instar larvae and 81.4% of pre-pupae being parasitized. The pteromalid was present in 7.0% of pre-pupae. Both parasitoids were reared to adulthood in the laboratory, with the pteromalid exhibiting continued generations, but the tachinid completing …

Abundance Of Coccinellids And Their Potential Prey In Field-Crop And Grass Habitats In Eastern South Dakota, Louis S. Hesler, Robert W. Kieckhefer, Michael M. Ellsbury

The Great Lakes Entomologist

A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s. In this study, coccinellids were sampled within field-crop and grass habitats in eastern South Dakota from 1990 to 1995 to survey for various coccinellid species and to determine any effects of habitat management on abundance. Field crops (maize, wheat-alfalfa intercrop, and alfalfa) were subjected to high, intermediate, or low crop-management intensity (CMI), and grass habitats were managed for stands of warm season, cool season, …

Linkages Between The Phenologies Of Jack Pine (Pinus Banksiana) Foliage And Jack Pine Budworm (Lepidoptera: Tortricidae), Beresford L. Cadogan, Roger D. Scharbach, Robert E. Krause, Linda S. Sloane, John A. Studens

The Great Lakes Entomologist

A field study conducted in 2001 and 2002 in the Michigan Upper Peninsula investigated seasonal associations between the development of jack pine, Pinus banksiana Lamb., and larvae of the jack pine budworm Choristoneura pinus Freeman (Lepidoptera: Tortricidae). There was almost no active relationship between post-diapause emerging second instars and elongation of vegetative shoots. Early instars were not closely synchronized with the flushing of current-year needle fascicles, which is required to optimize larval feeding. How- ever, there were close feeding and shelter relationships between early instars and year-2 pollen cone development. Associations with, and larval damage to, year-2 seed cones were …
