New And Additional Distribution Records For Several Rare Mayflies (Ephemeroptera) In Wisconsin, Richard A. Lillie

The Great Lakes Entomologist

One nymph and one exuviae of Acanthametropus pecatonica were collected in June 1991 from the Black River and Chippewa River, respectively. These specimens extend the known range of this rare species in Wisconsin to three large Mississippi River tributaries. Homoeoneuria ammophila was recorded in Wisconsin for the first time; nymphs were collected from the Black River and Sugar River. Nymphs of Macdunnoa persimplex, Metretopus borealis, Pentagenia vittigera, Pseudiron centralis, and Cercobrachys sp. were also encountered.

The Sand-Dwelling Predatory Mayfly Pseudiron Centralis In Michigan (Ephemeroptera: Pseudironidae), W. P. Mccafferty

(excerpt)

An examination of samples of Ephemeroptera larvae taken from 19 sites on the Pere Marquette River, Mason County, Michigan in October, 1990 and May, 1991 by A. G. B. Primack (Indiana University, Bloomington) revealed the presence of Pseudiron centralis McDunnough. This species was taken at seven sites between State Highway M37 and Rainbow Rapids, east of Ludington.

A Check List Of The Lepidoptera Of Beaver Creek State Park, Columbiana County, Ohio, Roy W. Rings, Eric H. Mezler

The Great Lakes Entomologist

Results of a comprehensive survey of Lepidoptera occurring at a 12,334 hectare natural area in Columbiana County. Ohio conducted in 1985 and 1990 is presented. Ten species of skippers, 27 species of butterflies and 597 species and forms of moths were identified and recorded. Euagrotis forbesi, and Spodoptera eridania had not previously been collected in Ohio; and Polia nimbosa and Idia laurenti have been designated as special interest since they are considered rare Ohio residents. The gypsy moth, Lymantria dispar was taken in bait traps and is the first record for that species in the Park. The presence of …

Factors Influencing Length And Volume Of Cells Provisioned By Two Passaloecus Species (Hymemoptera: Sphecidae), John M. Fricke

The Great Lakes Entomologist

Length of cells provisioned by Passaloecus areolatus and Passaloecus cuspidatus decreased as bore diameter increased, but volume of provisioned cells increased with increasing bore diameter. Activity of the parasitoid Omalus aneus increased length of provisioned cells. Wasp senescence did not result in increased cell length.

Holarctic Insects Adventive In Michigan: New And Additional Records (Homoptera, Heteroptera, Coleoptera, Neuroptera), A. G. Wheeler Jr.

The Great Lakes Entomologist

Fourteen European insects in the Homoptera (4 species), Heteroptera (5), Coleoptera (4), and Neuroptera (1) are reported from Michigan. Ten are new state records (one new Ohio record is given). The point of entry for most of the species is assumed to be the northeastern United States or Maritime Provinces of Canada. Possibilities of dispersal (natural and human-assisted) from centers of introduction in the Northeast, multiple introductions from Europe, and direct entry into the Great Lakes region are discussed.

Diagnostic Alleles From Electrophoresis Distinguish Two Noctuid Pest Species, Hydraecia Immanis And H. Micacea (Lepidoptera: Noctuidae)., J. Mark Scriber, Janice L. Bossart, Doozie Snider

The Great Lakes Entomologist

Native hop vine borer (Hydraecia immanis) and introduced potato stem borer (H. micacea) populations in Midwest corn have reached noticeable levels near the Great Lakes plant community ecotone between boreal forests and temperate deciduous forests. The hop vine borer is more specialized in its diet and occurs in corn generally south of the plant community ecotone, whereas the potato stem borer is polyphagous and occurs in corn mostly north of the Great Lakes plant transition zone. We analyzed the genetic composition of each species using cellulose acetate electrophoresis and resolved 19 loci of which 6 exhibited …

Seasonal Drift Of Lethocerus Americanus (Hemiptera: Belostomatidae) In A Lake Superior Tributary, Robert B. Dubois, Michael L. Rackouski

The Great Lakes Entomologist

Drifting adult Lethocerus americanus were captured and retained by an inclined-screen smolt trap during two field seasons in the Bois Brule River, Wisconsin. Seasonal peaks of drift occurred in spring for 4 weeks following ice out and in autumn for 7 -8 weeks from mid-September through ice formation, and may have continued under ice cover when our gear was not operated. These findings are consistent with the known movement pattern of these insects to fly from lentic habitats to streams to overwinter but also suggest longitudinal movement via drift, perhaps to reach specific overwintering sites. Drift was significantly correlated with …

The Return Of Hexagenia (Ephemeroptera: Ephemeridae) To The Lower Fox River, Wisconsin, Phillip A. Cochran

The Great Lakes Entomologist

Burrowing mayflies (Hexagenia bilineata) were collected in 1991 in the vicinity of the DePere dam on the Fox River, Brown County, Wisconsin. Because Hexagenia mayflies are indicators of good water quality, their emergence from the Fox River is evidence of improvement in conditions at the sediment-water interface.

Distribution Of The Water Scorpion Nepa Apiculata (Hemiptera: Nepidae) In Wisconsin, P. A. Cochran, A. P. Gripentrog, K. M. Stack

The Great Lakes Entomologist

The water scorpion Nepa apiculata Uhler was considered rare in Wiscon- sin by Hilsenhoff (1984), who collected only 11 individuals during a 25-year period. All of his collections were from overwintering sites, especially debris in streams, during early spring or autumn (Hilsenhoff, pers. comm.). He concluded that the species was restricted to southern Wisconsin. Recent collections indicate that N. apiculata is more widely distributed. These records, summarized below, are documented with specimens in the University of Wisconsin-Madison insect collection.

Observations On The Nesting Of Crabro Tenuis (Hymenoptera: Sphecidae), Frank E. Kurczewski, Richard C. Miller

The Great Lakes Entomologist

Three nests of Crabro tenuis were studied during June 1971-1972 in Oswego County, New York. Females constructed shallow but lengthy, multicelled nests in sand with the cells being built in clusters, sometimes in series. Females plugged the entrances with damp sand and occupied the burrows during midday. Paralyzed prey were stored head inward at the end of the burrow. The deeper cells in a cluster were excavated and provisioned first and the shallower cells built and stored later, as determined by the developmental stages of the wasps within the cells. From four to seven paralyzed, adult male flies were placed …

The Assassin Bugs Of Michigan (Heteroptera: Reduviidae), J. E. Mcpherson

Assassin bugs collected in Michigan and housed in the University of Michigan Museum of Zoology and the Michigan State University Entomology. Museum were used to compile a list of the state's species and subspecies. A total of 27 was found; an additional species, Empicoris parshleyi, was represented by a single specimen housed in the American Museum of Natural History. Eighteen of the 28 taxa represented new records for the state.

Aphidophagous Coccinellids In Alfalfa, Small Grains, And Maize In Eastern South Dakota, R. W. Kieckhefer, N. C. Elliott, D. A. Beck

The Great Lakes Entomologist

In a 13-year study of aphidophagous coccinellids associated with alfalfa (Medicago sativa), maize (Zea mays), and small grain crops in eastern South Dakota, the following species were consistently associated with the crops: Hippodamia convergens, H. tredecimpunctata tibialis, H. parenthesis, Coleomegilla maculata lengi, Coccinella transversoguttata richardsoni, Cycloneda munda, and Adalia bipunctata. All species except A. bipunctata were associated with each of the three crops, while A. bipunctata occurred only in maize. Relative abundances of each species varied among crops and among years. Although only seven species were associated with the crops, additional species were captured on …

Survival, Development And Population Dynamics Of Empoasca Fabae (Homoptera: Cicadellidae) On Three Legume Hosts, Stephen S. Peterson, John L. Wedberg, David B. Hogg

The Great Lakes Entomologist

Survival and development of potato leafhopper, Empoasca fabae, nymphs were measured on alfalfa (Medicago sativa), birdsfoot trefoil (Lotus corniculatus), and red clover (Trifolium pratense). Survival was not significantly different among host plants (mean = 62%). There was no interaction between sex and host plant for developmental time. Males developed significantly faster than females. Developmental time was fastest on alfalfa, intermediate on trefoil, and slowest on red clover. Plots of alfalfa, trefoil, and red clover were planted to compare the seasonal abundance of the potato leafhopper in the three forages. Nymphs were more abundant …

Morphological Differentiation Between Aphis Spiraecola And Aphis Pomi (Homoptera: Aphididae), Susan E. Halbert, David J. Voegtlin

The Great Lakes Entomologist

Aphis pomi and Aphis spiraecola, are both found on agriculturally important hosts such as apple and pear, and in trap collections. Their morphological similarity makes identification difficult. Examination of specimens of both species fom a wide geographical range demonstrated that available keys, especially those based on European material, were not always accurate for North American specimens. Data taken from North American specimens is presented and a key is provided to aid in the identification of trapped alatae preserved in alcohol as well as slide mounted alatae and apterae of these two species.

Effect Of Temperature On Development Rate And Survival Of Nomophila Nearctica (Lepidoptera: Pyralidae), Fredric D. Miller Jr., Joseph V. Maddox

The Great Lakes Entomologist

Development of Nomophila nearctica was studied under six constant tempera- tures in controlled temperature cabinets. Developmental threshold temperatures for egg, larval, and prepupal-pupal stages were 8.9, 1l.5, and 9.2°C. The overall mean developmental threshold temperature for all stages was 9.9°C. Degree-day summa- tions, based on the above threshold temperatures, averaged 50, 304, and 181 DD for the egg, larval, and prepupal-pupal stages, respectively. Total heat units of 535 DD are required for development from oviposition to adult emergence. Head capsule measurements indicated six larval instars.

The Parasitoid Complex Of Forest Tent Caterpillar, Malacosoma Disstria (Lepidoptera: Lasiocampidae), In Eastern Wyoming Shelterbelts, G. A. Knight, R. J. Lavigne, M. G. Pogue

The Great Lakes Entomologist

A parasitoid complex affecting the forest tent caterpillar, Malacosoma disstria, was investigated during 1978-79 in shelterbelts in eastern Wyoming. Egg parasitoids included five species: Ablerus clisiocampae, Ooencyrtus clisiocampae, Telenomus clisiocampae, Tetrastichus sp. 1 and Telenomus sp. Thirteen hymenopterous species and five dipterous species were reared from larvae and pupae of the forest tent caterpillar. The most common 5th-instar larval parasitoids were the tachinid flies, Lespesia archippivora and Archytas lateralis. Of the pupal parasitoids reared, 640/0 were Diptera and 36% were Hymenoptera. Four previously unrecorded parasitoids of M. disstria were reared: Cotesia alalantae, Macrocentrus irridescens, Pimpla sanguinipes erythropus, …

Differential Suitability Of 12 Great Lakes Tree Species For Papilio Canadensis (Lepidoptera: Papilionidae) Larval Survival And Growth, J. Mark Scriber

The Great Lakes Entomologist

Differential nutritional suitabilities of the 12 potential host plants of Papilio canadensis in the Great Lakes region of North America were determined with gravimetric techniques for penultimate and final larval instars. While leaf water content and leaf nitrogen content explain some of the variation, allelochemicals in different plants are likely to be involved in differential larval growth performances as well as mortal- ity of neonate larvae on tuliptree and spicebush. Oviposition tests using 3-choice arenas with quaking aspen, paper birch, and balsam poplar showed no strong host preferences. Factors affecting patterns of Papilio host use in the Great Lakes region …

Effects Of Soil Moisture On The Pupation Behavior Of Altica Subplicata (Coleoptera: Chrysomelidae), Kathleen M. Rickelmann, Catherine E. Bach

The Great Lakes Entomologist

The effects of soil moisture on the pupation behavior of a willow flea beetle, Attica subplicata, were studied with two laboratory experiments. To test the effect of soil moisture on the number of larvae pupating and pupal survival, we set up pupation chambers filled with sand with three different soil moistures: dry, moist, and wet. The number of larvae pupating was much greater in the moist sand and wet sand treatments than in the dry sand treatment. Pupal survival, as measured by the proportion of adults successfully emerging, was greater in the moist treatment than in the wet or …

Orientation Of Hylobius Pales And Pachylobius Picivorus (Coleoptera: Curculionidae) To Visual Cues, D.W. A. Hunt, K. F. Raffa

The Great Lakes Entomologist

Pitfall traps with above-ground silhouettes of various colors and diameters were used in field tests to evaluate the role of vision in host orientation by adult pales weevils, Hylobius pales, and pitch-eating weevils, Pachylobius picivorus. White traps (11 em outer diameter) baited with ethanol and turpentine caught significantly more weevils than similarly baited black or green traps (11 cm outer diameter). Trap diameter (range of 6-22 cm outer diameter) did not affect trap catch. Pitfall traps can be used to monitor root weevil populations in young pine plantations and Christmas tree farms, where they are major pests. These …

New Lepidoptera-Parasitoid Associations In Weedy Corn Plantings: A Potential Alternate Host For Ostrinia Nubilalis (Lepidoptera: Pyralidae) Parasitoids, Daniel M. Pavuk, Benjamin R. Stinner

The Great Lakes Entomologist

Larvae of the common sooty wing, Pholisora catullus, and pupae of the yellow-collared scape moth, Cisseps Fulvicollis, were collected in corn plantings containing different manipulated, indigenous weed communities to determine if these Lepidoptera had parasitoid species in common with the European corn borer, Ostrinia nubilalis. Pholisora catullus larvae were collected from lambsquarter, Chenopodium album, and redroot pigweed, Amaranthus retroflexus, whereas pupae of C. Julvicollis were obtained from corn. Four parasitoid species were reared from P. catulIus: Cotesia pholisorae, Oncophanes americanu (Hymenoptera: Braconidae), Gambrus ultimus, and Sinophorus albipalpus (Hymenoptera: Ichneumonidae). Of these, O. americanus and …

Host Plants And Habitats Of The Baltimore Checkerspot Butterfly, Euphydryas Phaeton (Lepidoptera: Nymphalidae), In The Great Lakes Region, Brian G. Scholtens

The Great Lakes Entomologist

The habitats and host plants of Euphydryas phaeton in the Great Lakes region are examined using data from several different populations spread over much of the region. The range of habitats and host plants used by this species is wider than commonly believed. While many populations are found in seasonal or permanent wetlands, others are located in dry, old fields or woodland areas. The host plants used vary with habitat, but they include all major primary hosts and many secondary hosts previously reported plus several new records. The biology of E. phaeton is shown to be similar to western Euphydryas …
