Gill Ventilation Rates Of Mayfly Nymphs (Ephemeroptera: Heptageniidae) As A Biomonitoring Technique, Richard A. MacKenzie, Jerry L. Kaster 2018 Wells National Estuarine Research Reserve

Gill Ventilation Rates Of Mayfly Nymphs (Ephemeroptera: Heptageniidae) As A Biomonitoring Technique, Richard A. Mackenzie, Jerry L. Kaster

The Great Lakes Entomologist

Gill ventilation frequency (GVF) of the mayfly nymph Stenacron interpunctatum (Ephemeroptera: Heptageniidae) was studied to assess the applicability of a relatively simple, real time video methodology and to assess the potential of GVF rates for use in a chronic assay of sediment pore water. Stenacron interpunctatum nymphs were exposed to pore water samples taken along a transect from the mouth of the Fox River to Sturgeon Bay in the Green Bay area of Lake Michigan. This transect has previously been shown to exhibit several distinct gradients in sediment and water column conditions with distance from the Fox River. The highest ...


Invertebrate Terrestrial Diversity Along A Gravel Road On Barrie Island, Ontario, Canada, Austine Luce, Mary Crowe 2018 Coastal Carolina University

Invertebrate Terrestrial Diversity Along A Gravel Road On Barrie Island, Ontario, Canada, Austine Luce, Mary Crowe

The Great Lakes Entomologist

Although roads have been a part of our landscape for hundreds of years, their impact on the plant and animal populations has only recently been studied. We examined the effect a gravel road had on terrestrial arthropod diversity in the Barrie Islands, Canada. Over a ten-week period during the summer of 1999 we systematically sampled ground and aerial terrestrial arthropods at 5, 10 and 15 m from a 250 m stretch of road. We collected nearly 5,000 insects the majority of which were Coleoptera, Diptera and Hymenoptera. We collected over 2,000 non-insect invertebrates that included representatives from the ...


Changes In The Butterflies (Lepidoptera) Of Winneshiek County, Iowa After 90 Years, Kirk J. Larsen, Jennifer A. Bovee 2018 Luther College

Changes In The Butterflies (Lepidoptera) Of Winneshiek County, Iowa After 90 Years, Kirk J. Larsen, Jennifer A. Bovee

The Great Lakes Entomologist

In 1908, Bert Porter reported the presence of 73 species of butterflies in the Decorah, Iowa area. Since then, no systematic surveys of the butterflies in the Decorah area have been completed despite extensive habitat changes and degradation of native prairie and timber that have occurred over the past 90 years. In 1998, an extensive survey of the butterflies of Winneshiek County confirmed the presence of 55 species of butterflies. Our findings generated a checklist of the butterflies currently found in Winneshiek County, and were compared to Porter's original list. Unfortunately, the regal fritillary, Speyeria idalia, and several other ...


Distribution Of Urophora Affinis And U. Quadrifasciata (Diptera: Tephritidae) For Biological Control Of Spotted Knapweed (Centaurea Maculosa) And Diffuse Knapweed (Centaurea Diffusa) In Michigan, R. F. Lang, R. D. Richard, J. Winkler, G. Wheeler 2018 USDA

Distribution Of Urophora Affinis And U. Quadrifasciata (Diptera: Tephritidae) For Biological Control Of Spotted Knapweed (Centaurea Maculosa) And Diffuse Knapweed (Centaurea Diffusa) In Michigan, R. F. Lang, R. D. Richard, J. Winkler, G. Wheeler

The Great Lakes Entomologist

Urophora affinis (Diptera: Tephritidae) and U. quadrifasciata (Diptera: Tephritidae) are two seedhead flies approved for release in the United States in 1971 and 1988, respectively for biological control of spotted and diffuse knapweed. United States Department of Agriculture, Animal Plant Health Inspection Service, Plant Protection Quarantine (APHIS) released a mixture of 4,000 adult U. affinis and U. quadrifasciata in Isabella County, Michigan, in 1994. No Urophora species were found in pre-release samples in seven counties in 1993. Samples collected in three counties in 1994, prior to the APHIS release, detected U. quadrifasciata in Menominee County. Surveys from 1998 to ...

Mantis Religiosa (Mantodea: Mantidae) In Door County, Wisconsin, Mark A. Kisselburg, Philip A. Cochran 2018 Saint Norbert College

Mantis Religiosa (Mantodea: Mantidae) In Door County, Wisconsin, Mark A. Kisselburg, Philip A. Cochran

The Great Lakes Entomologist

The European mantid (Mantis religiosa) has been observed at several sites spanning a distance of approximately 50 km in northern Door County, Wisconsin. A reliable sighting of an unidentified praying mantid on Chambers Island in Green Bay suggests the possibility that the species occurs there as well. Lake-induced moderation of the Door County climate may have resulted in conditions especially conducive for the establishment of European mantids.


Biological Control Of Alfalfa Blotch Leafminer (Diptera: Agromyzidae) In Ontario: Status And Ecology Of Parasitoids (Hymenoptera: Braconidae, Eulophidae) 20 Years After Introduction, George E. Heimpel, Francois Meloche 2018 University of Minnesota

Biological Control Of Alfalfa Blotch Leafminer (Diptera: Agromyzidae) In Ontario: Status And Ecology Of Parasitoids (Hymenoptera: Braconidae, Eulophidae) 20 Years After Introduction, George E. Heimpel, Francois Meloche

The Great Lakes Entomologist

Two European parasitoid species were released in Ontario during the late 1970's to control the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae). One of these, Dacnusa dryas (Nixon) (Hymenoptera: Braconidae), rapidly became established and the other, Chrysocharis liriomyzae (= C. punctifacies) (Delucchi) (Hymenoptera: Eulophidae) was never recovered in Ontario. In 1999, we found both D. dryas and C. liriomyzae parasitizing first-generation A. frontella in Ontario in 1999. The combined parasitism rate for both species as revealed by larval dissections was 97.5% by the end of the first A. frontella generation. Of the adult parasitoids reared, 86% were D ...


Studies On The Life Cycle And Transmission Of Cougourdella Sp., A Microsporidian Parasite Of Glossosoma Nigrior (Trichoptera: Glossosomatidae), Jeffrey S. Heilveil, Steven L. Kohler, Leellen F. Solter 2018 University of Illinois

Studies On The Life Cycle And Transmission Of Cougourdella Sp., A Microsporidian Parasite Of Glossosoma Nigrior (Trichoptera: Glossosomatidae), Jeffrey S. Heilveil, Steven L. Kohler, Leellen F. Solter

The Great Lakes Entomologist

The trichopteran Glossosoma nigrior, the dominant benthic invertebrate grazer in Michigan trout streams, hosts a microsporidian (Protozoa) pathogen, Cougourdella sp., which strongly regulates the population density of larvae in the stream. In order to better understand the interactions between these two species, two possible modes of pathogen transmission, oral and transovum, were investigated. While both sexes of adult G. nigrior were found to be infected with mature environmental spores, spores were not found associated with reproductive tissue. This suggests that transovum transmission does not occur in this system. Glossosoma nigrior, when ex- posed to viable spores taken from infected larvae ...


Decline Of Gomphus Fraternus Fraternus (Odonata: Gomphidae) In Lake Erie, Paul M. Catling 2018 Valparaiso University

Decline Of Gomphus Fraternus Fraternus (Odonata: Gomphidae) In Lake Erie, Paul M. Catling

The Great Lakes Entomologist

Collections and literature reports indicate that Gomphus fraternus fraternus was abundant on the shoreline of Lake Erie prior to 1960, and "tens of thousands" were reported at Long Point Bay. After 1960 there were no reports from the shoreline, although there have been a number of comprehensive studies that have included the shoreline area and a number of Odonata specialists have also visited the Lake Erie shoreline regularly. A survey of portions of the Lake Erie shoreline, including the Long Point Bay area in 1999 and 2000, during the established peak and late peak flight period in southwestern Ontario, did ...


Comparison Of Two Population Sampling Methods Used In Field Life History Studies Of Mesovelia Mulsanti (Heteroptera: Gerromorpha: Mesoveliidae) In Southern Illinois, Steven J. Taylor, J. E. McPherson 2018 Illinois Natural History Survey

Comparison Of Two Population Sampling Methods Used In Field Life History Studies Of Mesovelia Mulsanti (Heteroptera: Gerromorpha: Mesoveliidae) In Southern Illinois, Steven J. Taylor, J. E. Mcpherson

The Great Lakes Entomologist

A field life history study of Mesovelia mulsanti was conducted in south­ern Illinois, the results of which are compared with those from an earlier study also conducted in southern Illinois. The two studies differed in the collecting techniques used (quadrat sampler versus aquatic net). Results of the present study give a clearer picture of the life history of this insect be­ cause the quadrat sampler collected representative samples of nymphs and adults more effectively than the aquatic net and, thus, the quadrat samples more accurately represented the actual chronology of the annual generations.


Distribution Of First Instar Gypsy Moths (Lepidoptera: Lymantriidae) Among Saplings Of Four Tree Species Common In The Great Lakes Region, J. L. Stoyenoff, J. A. Witter 2018 University of Michigan

Distribution Of First Instar Gypsy Moths (Lepidoptera: Lymantriidae) Among Saplings Of Four Tree Species Common In The Great Lakes Region, J. L. Stoyenoff, J. A. Witter

The Great Lakes Entomologist

We examined the inter-tree distribution of first instar gypsy moth larvae under natural dispersal conditions in the field in Michigan in 1991. The study focused on saplings of northern red oak (Quercus rubra), white oak (Q. alba), red maple (Acer rubrum), and witch-hazel (Hamamelis virginiana), which are common understory components of forests in the Great Lakes region. Large-volume trees with foliage that is well-developed early in the spring should provide an excellent surface area for catching newly-hatched gypsy moth larvae, which are randomly dispersed by wind in the spring around the time of leaf flush or shortly thereafter. Comparing across ...

Leucanthiza Dircella (Lepidoptera: Gracillariidae): A Leafminer Of Leatherwood, Dirca Palustris, Toby R. Petrice, Robert A. Haack, William J. Mattson, Bruce A. Birr 2018 USDA Forest Service

Leucanthiza Dircella (Lepidoptera: Gracillariidae): A Leafminer Of Leatherwood, Dirca Palustris, Toby R. Petrice, Robert A. Haack, William J. Mattson, Bruce A. Birr

The Great Lakes Entomologist

Leatherwood, Dirca palustris (Thymelaeaceae), is an understory shrub ranging throughout most of the eastern and central United States and adjacent Canada. During 1997-1999, we conducted studies to identify and assess the impact of a leafminer that was causing significant damage to leather- wood plants in eastern Gogebic County, Michigan. Leucanthiza dircella was identified as the only insect responsible for the leaf mining activity on leatherwood. In northern Michigan, L. dircella completed one generation per year. Adult moths were captured on yellow sticky panels suspended from leatherwood branches. In 1997 and 1998, most adults were captured during the first sampling period ...


Seasonal Occurrence Of The Sod Webworm Moths (Lepidoptera: Crambidae) Of Ohio, Harry D. Niemczyk, David J. Shetlar, Kevin T. Power, Douglas S. Richmond 2018 Ohio State University

Seasonal Occurrence Of The Sod Webworm Moths (Lepidoptera: Crambidae) Of Ohio, Harry D. Niemczyk, David J. Shetlar, Kevin T. Power, Douglas S. Richmond

The Great Lakes Entomologist

While nearly 100 species of sod webworms are known to occur in North America, the species complex and seasonal occurrence of these moths has been documented in relatively few states. For Ohio, there is little published record of the sod webworm species complex, and the seasonal occurrence of only a few economically important species has been documented. Using black light traps, sod web worm adult flight activity was monitored over the course of three to five years at four different locations throughout Ohio. In this paper we report the seasonal occurrence of sod web worms species captured at these locations ...


Arhyssus Hirtus (Hemiptera: Heteroptera: Rhopalidae) In Minnesota: The Inland Occurrence Of An East Coast Species, John D. Lattin, John Haarstad 2018 Oregon State University

Arhyssus Hirtus (Hemiptera: Heteroptera: Rhopalidae) In Minnesota: The Inland Occurrence Of An East Coast Species, John D. Lattin, John Haarstad

The Great Lakes Entomologist

Arhyssus hirtus (Hemiptera: Heteroptera: Rhopalidae), is reported from the Cedar Creek Natural History Area, a Long-Term Ecological Research site, outside of Minneapolis, Minnesota where over 4000 species of arthropods have been collected. This species has previously been known only from a narrow zone along the sandy edges of the Atlantic Ocean (Maryland, Massachusetts, New Jersey and New York). The species is known on Hudsonia tomentosa at these ocean sites, but other hosts may be involved at Cedar Creek. This small species of Arhyssus occurs in both micropterous and macropterous forms, unusual for this genus. Thus far, only micropterous forms have ...

New Michigan Tick (Acari: Ixodidae) And Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds, William C. Scharf 2018 Lake Superior State University

New Michigan Tick (Acari: Ixodidae) And Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds, William C. Scharf

The Great Lakes Entomologist

Banding and censusing large numbers of gull chicks over a 30-year period on Great Lakes islands has produced a collection of five individual ticks from two Herring Gull (Larus argentatus) chicks. The tick species, Hemaphysalis leporispalustris, found on the gulls is commonly found on Snowshoe Hares (Lepus americanus). Although this represents an apparently uncom­mon record on Herring Gulls, this host could be an important source of aerial vector dispersal during regular cyclic hare/tick population peaks. Populations of the flea, Ceratophyllus lari, have increased rapidly in ground nesting Double-crested Cormorant (Phalacrocorax auritus) colonies from none 16 years ago. The ...


Color, Bacteria, And Mosquito Eggs As Ovipositional Attractants For Aedes Aegypti And Aedes Albopictus (Diptera: Culicidae), Steven G. Pavlovich, C. Lee Rockett 2018 Mosquito Control, Inc.

Color, Bacteria, And Mosquito Eggs As Ovipositional Attractants For Aedes Aegypti And Aedes Albopictus (Diptera: Culicidae), Steven G. Pavlovich, C. Lee Rockett

The Great Lakes Entomologist

Selected bacterial washes, color, and mosquito eggs were comparatively examined as ovipositional attractants for Aedes aegypti and Aedes albopictus. Any evidence of additive activity was noted. All colored washes alone were preferred over selected bacterial washes. The combinations of color and bacteria in a single wash were better attractants for oviposition than colored washes alone. The bacterial content of the breeding water was a more important factor than egg presence in oviposition site selection.
