(excerpt)

I was eager to review this publication. When I was a young person, first starting the pursuit of Lepidoptera, any literature that increased my knowledge was as valuable as the specimens I collected. Checklists were especially welcome. A primary purpose for the formation of The Ohio Lepidopterists society was to record the occurrence of Lepidoptera in Ohio. My ardent commitment to document Ohio's fauna over the past 20 years gives me insight into the work necessary to create and produce a publication of this type.

First Report Of The Alfalfa Blotch Leafminer (Diptera: Agromyzidae), And Selected Parasites (Hymenoptera: Eulophidae) In Minnesota And Wisconsin, Usa, W. D. Hutchison, P. K. O'Rourke, D. W. Bartels, E. C. Burkness, J. C. Luhman, J. Heard

The Great Lakes Entomologist

Alfalfa blotch leafminer, Agromyza frontella, has been a serious pest of alfalfa, Medicago sativa, in the northeastern U.S. and in eastern Ontario, Canada. Until recently, the western edge of the A. frontella distribution in the U.S. was limited to eastern Ohio. We document for the first time, the occurrence of A. frontella in Minnesota and Wisconsin. Alfalfa stems damaged by A. frontella, based on adult feeding punctures, obvious blotched leafmining or the presence of larvae, were first found in 3 northern Minnesota coun­ties during October, 1994. Infested counties included Lake of the Woods, Cook and Lake, all ...


Unusual Sex Allocation In A Solitary Parasitoid Wasp, Sphaeropthalma Pensylvanica (Hymenoptera: Mutillidae), Robert W. Matthews Dec 2017

Unusual Sex Allocation In A Solitary Parasitoid Wasp, Sphaeropthalma Pensylvanica (Hymenoptera: Mutillidae), Robert W. Matthews

The Great Lakes Entomologist

Sphaeropthalma pensyluanica reared from cocoons of the organ pipe mud dauber, Trypoxylon politum from Georgia over several years yielded only adult males. Possible explanations for this sex-biased emergence from this host are (1) obligatory heteronomous heterotrophy, in which the two sexes develop on entirely different hosts; (2) differential mortality in the immature stage, with female larvae dying during development; and (3) facultative size- dependent sex allocation, with female eggs laid only on hosts smaller than T. politum.


Sex-Related Color Patterns In Elytral Vittae Of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae), Louis S. Hesler, Leslie Hammack Dec 2017

Sex-Related Color Patterns In Elytral Vittae Of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae), Louis S. Hesler, Leslie Hammack

The Great Lakes Entomologist

We evaluated the color patterns of elytral vittae by sex in adults of Diabrotica virgifera virgifera leConte. Our study examined >1000 beetles taken from a field population, a laboratory colony, and a reference collection containing 712 specimens from 15 of the United States and from the province of Ontario, Canada. The humeral and sutural vittae of each beetle's elytra were classified as being separate, partially confluent, or totally confluent with each other. The distribution of these elytral patterns was not independent of sex. Males tended to have confluent or partially confluent vittae, whereas females largely had separate vittae. Nonetheless ...


Chemiluminescent Tags For Tracking Insect Movement In Darkness: Application To Moth Photo-Orientation, Joseph L. Spencer, Lawrence J. Gewax, James E. Keller, James R. Miller Dec 2017

Chemiluminescent Tags For Tracking Insect Movement In Darkness: Application To Moth Photo-Orientation, Joseph L. Spencer, Lawrence J. Gewax, James E. Keller, James R. Miller

The Great Lakes Entomologist

The flight tracks of Manduca sexta (Lepidoptera: Sphingidae) flying toward a 5 watt incandescent light bulb were recorded under low light conditions with the aid of a camera-mounted photomultiplier and a glowing marker technique. Small felt pads bearing a chemiluminescent (glowi ma­erial, Cyalume®, were affixed to the abdomens of free-flying moths. insects orienting to a dim incandescent bulb were easily visible to the naked eye and were clearly captured on videotape. On their initial approach to the light source, M. sexta were found to orient at a mean angle of -0.220 ± 2.70 (mean ± SEM). The speed of ...


Tomicus Piniperda (Coleoptera: Scolytidae) Reproduction And Behavior On Scotch Pine Christmas Trees Taken Indoors, Robert A. Haack, Robert K. Lawrence Dec 2017

Tomicus Piniperda (Coleoptera: Scolytidae) Reproduction And Behavior On Scotch Pine Christmas Trees Taken Indoors, Robert A. Haack, Robert K. Lawrence

The Great Lakes Entomologist

Tomicus piniperda, the pine shoot beetle, is an exotic insect that was first found in North America in 1992. A federal quarantine currently restricts movement of pine products, including Christmas trees, from infested to uninfested counties. We conducted a study to determine if T. piniperda would re- produce in Christmas trees that were cut and taken indoors during the Christmas season. Twelve Scotch pine, Pinus sylvestris, Christmas trees infested with overwintering T. piniperda beetles were cut in Indiana in early December 1993 and taken to Michigan. Four trees were dissected immediately, while the other 8 trees were taken indoors, placed ...


Habitat Associations Of Sympatric Violet-Feeding Fritillaries (Euptoieta, Speyeria, Boloria) (Lepidoptera: Nymphalidae) In Tallgrass Prairie, Ann B. Swengel Dec 2017

Habitat Associations Of Sympatric Violet-Feeding Fritillaries (Euptoieta, Speyeria, Boloria) (Lepidoptera: Nymphalidae) In Tallgrass Prairie, Ann B. Swengel

The Great Lakes Entomologist

At 106 tallgrass prairies in the midwestern USA, 18,055 individuals of six fritillary species (Lepidoptera: Nymphalidae) were counted in 552.9 hr and 987.1 kill of transect survey effort from 14 June to 13 September during 1988-96. The relative abundance of Euptoieta claudia, Speyena cybele, S. aphrodite, S. idalia, Boloria selene, and B. bellona was analyzed for significant patterns relative to five habitat factors. Topographic diversity (i.e., whether the site was uniform or contained both uplands and lowlands) produced the most significant effects. Prairie patch size and vegetation type (wet, mesic, dry) also produced numerous significant patterns ...

Resistance Of Scotch Pine Varieties To Zimmerman Pine Moth (Lepidoptera: Pyralidae) And Its Impact On Sales In A Choose And Cut Christmas Tree Plantation, Clifford S. Sadof Dec 2017

Resistance Of Scotch Pine Varieties To Zimmerman Pine Moth (Lepidoptera: Pyralidae) And Its Impact On Sales In A Choose And Cut Christmas Tree Plantation, Clifford S. Sadof

The Great Lakes Entomologist

Nine varieties of Scotch pine, Pinus sylvestris, were assessed for their susceptibility to Zimmerman pine moth, Dioryctria zimmermani, in a choose and cut Christmas tree plantation. Trees were examined for wounds to estimate their susceptibility to this pest 7 years after planting in the field. Numbers of trees remaining after seasonal sales in years 7 and 8 were used to estimate marketability of each variety. Infestation rates varied significantly among varieties (11-75%). After sales, proportions of trees remaining also varied significantly among varieties (7-52%). Although Belgian trees were the most moth resistant, they were the least purchased by the public ...

One hundred and forty-three species of mayflies are reported from the state of Tennessee. Sixteen species (Ameletus cryptostimulus, Choroterpes basalis, Baetis virile, Ephemera blanda, E. simulans, Ephemerella berneri, Heterocloeon curiosum, H. petersi, Labiobaetis ephippiatus, Leptophlebia bradleyi, Macdunnoa brunnea, Paraleptophlebia assimilis, P. debilis, P. mollis, Rhithrogenia pellucida and Siphlonurus mirus) are reported for the first time. Rare and vulnerable species occurring in the state are also discussed. This represents the first comprehensive statewide list of mayflies for Tennessee.


New Records Of Michigan Cicadidae (Homoptera), With Notes On The Use Of Songs To Monitor Range Changes, David Ciszek Marshall, John R. Cooley, Richard D. Alexander, Thomas E. Moore Dec 2017

New Records Of Michigan Cicadidae (Homoptera), With Notes On The Use Of Songs To Monitor Range Changes, David Ciszek Marshall, John R. Cooley, Richard D. Alexander, Thomas E. Moore

The Great Lakes Entomologist

We present records of Diceroprocta vitripennis, Tibicen chloromera, and Tibicen pruinosa (new state record) in Michigan. Monitoring geographic range changes and population size differences by song suggests several population situations for cicadas: (1) sizable populations in most areas of apparently good habitat; (2) widely separated single individuals or small populations on the edges of populated regions, representing range extensions that may be of limited duration; (3) one or a few individuals present only once, probably transferred in soil on roots, and ultimately unsuccessful. Species- specific calling songs allow sensitive measurement of species' range changes.

Epizootiology Of The Fungal Pathogen, Zoophthora Phytonomi (Zygomycetes: Entomophthorales) In Field Populations Of Alfalfa Weevil (Coleoptera: Curculionidae) Larvae In Illinois, Marilyn J. Morris, Stephen J. Roberts, Joseph V. Maddox, Edward J. Armbrust

The Great Lakes Entomologist

The influence of the fungal pathogen, Zoophthora phytonomi, on larvae of the alfalfa weevil, Hypera postica, was studied in three alfalfa fields in Illinois. Disease epizootics occurred in all three fields and disease onset was ob- served within a fairly narrow range of degree day accumulations. At the height of each epizootic, percentages of infected larvae were between 80 and 100%, and the fungus contributed to the collapse of the weevil population in each field. Percent parasitism by the larval parasitoids, Bathyplectes cur­culionis and B. anurus, was lower in our fields than is common in mid-season alfalfa weevil populations ...


Effects Of Hybrid Poplar (Salicaceae) Clone And Phenology On Gypsy Moth (Lepidoptera: Lymantriidae) Performance In Wisconsin, James J. Kruse, Kenneth F. Raffa Dec 2017

Effects Of Hybrid Poplar (Salicaceae) Clone And Phenology On Gypsy Moth (Lepidoptera: Lymantriidae) Performance In Wisconsin, James J. Kruse, Kenneth F. Raffa

The Great Lakes Entomologist

Gypsy moth (Lymantria dispar) developmental interactions with two hybrid Populus species clones were studied in laboratory trials. Significant differences in larval performance were found between clones and within the same clone at different phenological states. No larvae were able to complete development on clone NM6. All gypsy moth larvae feeding on clone NC5271 survived when leafflush was synchronized with gypsy moth eclosion in early May. However, neonates feeding on NC5271 foliage in July experienced in- creased mortality. Weights of surviving gypsy moth larvae feeding on NC5271 foliage in May versus July were not significantly different.

Natural Enemies Of Cranberry Fruitworm, Acrobasis Vaccinii, (Lepidoptera: Pyraudae) In Michigan Highbush Blueberries, Dogulas A. Murray, Robert D. Kriegel, James W. Johnson, Angus J. Howitt

The Great Lakes Entomologist

A two-year study was conducted in Michigan highbush blueberries to determine the complex of parasitoids attacking cranberry fruitworm, Acrobasis vaccinii. Eight parasitoid species and one fungal pathogen were collected. Parasitism of collected hosts ranged from 6.6% to 28.1%. The more common larval parasitoid encountered was Campoletis patsuiketorum (Hymenoptera: Ichneumonidae). The more common parasitoid recovered from fruitworm hibernacula was Villa lateralis (Diptera: Bombyliidae). This study documented six unreported natural enemies of cranberry fruitworm, including C. patsuiketorum; V. lateralis; Diadegma compressum (Hymenoptera: Ichneumonidae); Compsilura concinnata (Diptera: Tachinidae); Memorilla pyste (Diptera: Tachinidae); an undescribed Microtypus species (Hymenoptera: Braconidae); and a fungal ...


Oviposition By The Banded Sunflower Moth, Cochylis Hospes (Lepidoptera: Cochylidae) In Response To Helianthus Annuus Pollen, John F. Barker, Sharon Grugel Dec 2017

Oviposition By The Banded Sunflower Moth, Cochylis Hospes (Lepidoptera: Cochylidae) In Response To Helianthus Annuus Pollen, John F. Barker, Sharon Grugel

The Great Lakes Entomologist

Oviposition on an artificial substrate by the banded sunflower moth Cochylis hospes Walsingham was examined in response to sunflower pollen (Helianthus annuus) and sunflower pollen extract. Sunflower pollen in quantities as small as 0.2 mg significantly reduced oviposition on an artificial substrate relative to a control without pollen. Aqueous pollen extract applied to the artificial substrate significantly reduced oviposition with respect to the control substrate that was treated with solvent. Banded sunflower moths have gained some reproductive or competitive advantage by ovipositing on the bracts of sunflower and a deterrent effect of pollen could, at least in part, have ...

A New Larval Record Of Perlinella Drymo (Plecoptera: Perlidae) For Michigan, Ethan Bright Dec 2017

A New Larval Record Of Perlinella Drymo (Plecoptera: Perlidae) For Michigan, Ethan Bright

The Great Lakes Entomologist

The presence of larvae of Perlinella drymo in Michigan is documented for the first time. A total of 7 individuals were collected from Iron Creek, a tributary of the River Raisin watershed located in southeastern Michigan. Gut analysis of one specimen provided evidence for a carnivorous diet. The location from which larvae were collected indicate a preference during winter for stabilized undercut banks with little or no flow and accumulated organic debris upon sand and gravel substrate.

A Migration Study Of Stelidota Geminata (Coleoptera: Nitidulidae), Roger N. Williams, M. Sean Ellis, Dan S. Fickle, Scott T. Bloom

The Great Lakes Entomologist

The strawberry sap beetle, Stelidota geminata (Say), is a major pest of strawberries in the northeastern United States. Further knowledge of the migratory habits of this insect pest can enhance the effectiveness of pest management strategies. This nitidulid was shown to migrate from its overwintering sites to one of its primary reproductive sites, strawberry fields, in late May. The beetle population peaked in the third week in July, 1993 in the strawberry field and then gradually declined. In 1994, the peak, as well as the total population, was much greater than in 1993. Furthermore, S. geminata was concentrated in the ...
