Ecological Observations On Predatory Coccinellidae (Coleoptera) In Southwestern Michigan, K. M. Maredia, S. H. Gage, D. A. Landis, T. M. Wirth

The Great Lakes Entomologist

Ecological observations on habitat utilization by thirteen species of predatory Coccinellidae were made at a southern Michigan site during 1989 and 1990. Most of species were common during both years and used both agricul- tural and uncultivated habitats. Coccinella septempunctata and Coleomegilla maculata, were the most abundant in agricultural crops (alfalfa, maize, soy- bean and triticale), whereas Adalia bipunctata and Cycloneda munda, were the most abundant in deciduous and bushy habitats.

Factors Influencing Oviposition In Aedes Triseriatus (Diptera: Culicidae), Jeffrey Beehler, Sharon Lohr, Gene Defoliart

The Great Lakes Entomologist

Five factors associated with natural oviposition sites were tested for their attractancy to ovipositing Aedes triseriatus, including dyed oviposition water, presence of decaying organic matter, a dark oviposition container, water in which conspecific larvae have been reared to the 4th instar and the presence of eggs on the balsa wood oviposition substrate. A replicated fractional factorial design was used to examine the effects of the above factors on oviposition behavior in laboratory experiments. Regression analysis showed dyed oviposition water and eggs on the oviposition substrate to be statistically significant attractants for ovipositing A. triseriatus females. The attraction to dyed …

Effects Of Neighboring Nectar-Producing Plants On Populations Of Pest Lepidoptera And Their Parasitoids In Broccoli Plantings, J. Z. Zhao, G. S. Ayers, E. J. Grafius, F. W. Stehr

The Great Lakes Entomologist

Eggs and larvae of the imported cabbageworm, Pieris rapae, were much more abundant in broccoli interplanted with nectar-producing plants than in broccoli monoculture. More diamondback moth larvae, Plutella xylostella, occurred in broccoli interplanted with or adjacent to nectar-producing plants than in broccoli monoculture. Density of cabbage looper larvae, Trichoplusia ni, was similar among the three types of broccoli plantings. For Cotesia rubecula, established in Michigan after introduction from Yugoslavia, pupae were more numerous in broccoli interplanted with nectar-producing plants than in other plots. High parasitism rates of diamondback moth, mainly by Diadegma insulare, were observed in …

Suitability Of Selected Broad-Leaved Weeds For Survival And Growth Of Two Stalk-Boring Hydraecia Species (Lepidoptera: Noctuidae), Bruce L. Giebunk, J. Mark Scriber, John L. Wedberg

The Great Lakes Entomologist

Third instar hop vine borer (Hydraecia immanis) and potato stem borer (H. micacea) are new pest species on corn in the Midwest. Early instar larvae feed on small-stemmed grasses, and later instar larvae switch to broad- stemmed hosts to complete development. In order to assess potential suitability of various weeds of corn fields, larvae were reared on seven selected broad- leaved plants for 16-18 days under greenhouse conditions to determine their feeding behavior and performance. Domestic plants included hop (Humulus lupulus) and potato (Solanum tuberosum); weed species included curly dock (Rumex crisp us), redroot pigweed …

Effects Of Aspen Phenolic Glycosides On Gypsy Moth (Lepidoptera: Lymantriidae) Susceptibility To Bacillus Thuringiensis, Gavin E. Arteel, Richard L. Lindroth

The Great Lakes Entomologist

Performance of the gypsy moth, Lymantria dispar, on quaking aspen, Populus tremuloides, is strongly affected by foliar concentrations of phenolic glycosides. Because the microbial insecticide Bacillus thuringiensis is widely used against gypsy moths and has a mode of action similar to that of phenolic glycosIdes, we investigated the combined effects of the two toxins on gypsy moth larvae. The experimental design was a 2 x 2 factorial: two levels (0, +) of phenolicglycosides for each of two levels (0, +) of B. thuringiensis. The toxins were incorporated into artificial diets and bioassayed against first and fourth instars. …

Control Of Aphids On Spring Oats And Winter Wheat With Slow Release Granular Systemic Insecticides, Jaime E. Araya, Sue E. Cambron

The Great Lakes Entomologist

Aphid infestations (Homoptera: Aphididae) on spring oat (Avena sativa) cv. 'Ogle', and during the fall on winter wheat (Triticum aestivum) cv. 'Clark', composed mainly of Rhopalosiphum padi and Macrosiphum avenae, were reduced with applications at the 2-3 leaf stage of slow release granular formulations of acephate, carbofuran, and disulfoton, compared with carbofuran 15G and untreated controls, in field trials during 1990-1991 in northwestern Indiana. These field results corroborated those obtained by previous studies with the same formulations and dosages in the laboratory.

In oat, all insecticide treatments reduced aphid populations and percent- age aphid~infested plants, …

Detection Of Prolonged Diapause Of Northern Corn Rootworm In Michigan (Coleoptera: Chrysomelidae), D. A. Landis, E. Levine, M. J. Haas, V. Meints

The Great Lakes Entomologist

Prolonged diapause of northern corn rootworm, while known from other Midwestern states, has not previously been reported in Michigan. Populations of northern corn rootworm, (Diabrotica barberi) from two first-year corn fields in Genesee County, Michigan were examined for prolonged egg diapause. Pro- longed diapause was suspected in these populations due to an unusually high proportion of northern versus western corn rootworms in these fields. Eggs obtained from females collected at these sites were reared in the laboratory for two years. The presence of the prolonged diapause trait was confirmed in one population by eggs which hatched following two …

Riffle Beetles Of Wisconsin (Coleoptera: Dryopidae, Elmidae, Lutrochidae, Psephenidae) With Notes On Distribution, Habitat, And Identification, William L. Hilsenhoff, Kurt L. Schmude

The Great Lakes Entomologist

Twenty-four species of Elmidae, three species of Psephenidae, two species of Dryopidae, and one species of Lutrochidae were represented among 33,351 riffle beetles that were identified from Wisconsin. Almost all were found in streams, but some inhabited wave-swept lake margins and spring-ponds. Adults and larvae of eight species were collected almost exclusively from submerged, decaying wood, while those of most other species inhabited rock or gravel substrates, especially in stream riffles, and only occasionally were found in wood; adults of three species of Dubiraphia were found also on macrophytes. The presence of Stenelmis antennalis, S. fuscata, and S. …

Further Eastern Range Extension And Host Records For Leptoglossus Occidentalis (Heteroptera: Coreidae): Well-Documented Dispersal Of A Household Nuisance, Wayne K. Gall

The Great Lakes Entomologist

Leptoglossus occidentalis is reported for the first time from Connecticut, New York, Ontario, Pennsylvania, and Wyoming, representing an eastern range extension from Indiana and Michigan. Tsuga canadensis and Pinus mugo are added to the long list of coniferous hosts of this coreid. Approximately 233 of 316 northeastern specimens were collected inside or on the outside of buildings from August-May, confirming previous observations that L. occidentalis uses buildings for overwintering. Isolated records from Con- necticut and eastern Pennsylvania suggest human-mediated dispersal may augment its natural dispersal. The pattern of distribution records on a map of North America identifies L. occidentalis as …

The Food Plants And Distribution Of The American Plum Borer (Lepidoptera: Pyralidae), David J. Biddinger, Angus J. Howitt

The Great Lakes Entomologist

The North American geographical and host plant distributions for the American plnm borer, Euzophera semifuneralis, are reported. Literature and curatorial surveys found the plum borer to be present in 34 states in the U. S. as well as parts of Canada, Mexico, and South America. Pheromone surveys and direct observation found it to be present in high numbers in most cherry and plum orchards in Michigan and in 28 counties of the lower peninsula. A very wide host range representing 15 plant families was found, with most host species in the Rosaceae.

The Complexities Of Counting Fish: Engaging Citizen Scientists In Fish Monitoring, Karen H. Bieluch, Theodore Willis, Jason Smith, Karen A. Wilson

New Hampshire EPSCoR

Data gathered by citizen scientists can help ecologists understand long-term trends and can improve the quality and quantity of data about a resource. In Maine and Massa­chusetts, numerous citizen science programs collect data on river herring, anadromous fish that migrate each spring from the ocean to spawn in rivers and lakes. In collabora­tion with state and local resource managers and academic institutions, these programs aim to protect and restore river herring, improve local watersheds, and in some cases, support commercial harvesting. To better understand how programs are run and how data are used by managers, we interviewed program coordinators and …

Invasive Coqui Frogs Are Associated With Greater Abundances Of Nonnative Birds In Hawaii, Usa, Robyn L. Smith, Karen H. Beard, David N. Koons

Wildland Resources Faculty Publications

The global spread of invasive species has created significant challenges for avian conservation. Introduced predators and pathogens have long been recognized for their direct negative effects on birds, but introduced amphibians can reach high densities on islands with no native amphibians, where they interact with native species. The coqui frog (Eleutherodactylus coqui), introduced to the Hawaiian Islands in the late 1980s, could have significant impacts on birds because it is fully terrestrial and achieves high densities. Coquis have been hypothesized to compete with native birds for invertebrate prey, but could also serve as a novel food resource for birds that …

Reef Fish Assemblage Biogeography Along The Florida Reef Tract, Cory Ames

HCNSO Student Theses and Dissertations

Understanding the biogeography of reef fish assemblages is paramount to reef conservation, management, and conducting appropriate population survey designs. Reef fish assemblages are a multispecies complex of reef-associated fish and are shaped by multiple environmental and biological factors (e.g. temperature, depth, benthic habitat, and topographic relief), which determine the species constituents residing in an area. Assemblages typically change with latitude where the number of families, genera, and/or densities of species specific to warmer climates decrease poleward into colder climate regimes. The Florida Reef Tract (FRT) extends for 595 km from the Dry Tortugas in the south-west to Martin County in …

BACKGROUND: While age and the APOE ε4 allele are major risk factors for Alzheimer's disease (AD), a small percentage of individuals with these risk factors exhibit AD resilience by living well beyond 75 years of age without any clinical symptoms of cognitive decline.

METHODS: We used over 200 "AD resilient" individuals and an innovative, pedigree-based approach to identify genetic variants that segregate with AD resilience. First, we performed linkage analyses in pedigrees with resilient individuals and a statistical excess of AD deaths. Second, we used whole genome sequences to identify candidate SNPs in significant linkage regions. Third, we replicated SNPs …

Taking Control: Reorganization Of The Host Cytoskeleton By Chlamydia., Jordan Wesolowski, Fabienne Paumet

Department of Microbiology and Immunology Faculty Papers

Both actin and microtubules are major cytoskeletal elements in eukaryotic cells that participate in many cellular processes, including cell division and motility, vesicle and organelle movement, and the maintenance of cell shape. Inside its host cell, the human pathogen Chlamydia trachomatis manipulates the cytoskeleton to promote its survival and enhance its pathogenicity. In particular, Chlamydia induces the drastic rearrangement of both actin and microtubules, which is vital for its entry, inclusion structure and development, and host cell exit. As significant progress in Chlamydia genetics has greatly enhanced our understanding of how this pathogen co-opts the host cytoskeleton, we will discuss …

The Autophagy-Related Beclin-1 Protein Requires The Coiled-Coil And Bara Domains To Form A Homodimer With Submicromolar Affinity, Matthew J. Ranaghan, Michael A. Durney, Michael F. Mesleh, Patrick R. Mccarren, Colin W. Garvie, Douglas S. Daniels, Kimberly L. Carey, Adam P. Skepner, Beth Levine, Jose R. Perez

Chemistry Faculty Publications

Beclin-1 (BECN1) is an essential component of macroautophagy. This process is a highly conserved survival mechanism that recycles damaged cellular components or pathogens by encasing them in a bilayer vesicle that fuses with a lysosome to allow degradation of the vesicular contents. Mutations or altered expression profiles of BECN1 have been linked to various cancers and neurodegenerative diseases. Viruses, including HIV and herpes simplex virus 1 (HSV-1), are also known to specifically target BECN1 as a means of evading host defense mechanisms. Autophagy is regulated by the interaction between BECN1 and Bcl-2, a pro-survival protein in the apoptotic pathway that …

Genetic Signatures For Helicobacter Pylori Strains Of West African Origin, Kennady K. Bullock, Carrie L. Shaffer, Andrew W. Brooks, Ousman Secka, Mark H. Forsyth, Mark S. Mcclain, Timothy L. Cover

Veterinary Science Faculty Publications

Helicobacter pylori is a genetically diverse bacterial species that colonizes the stomach in about half of the human population. Most persons colonized by H. pylori remain asymptomatic, but the presence of this organism is a risk factor for gastric cancer. Multiple populations and subpopulations of H. pylori with distinct geographic distributions are recognized. Genetic differences among these populations might be a factor underlying geographic variation in gastric cancer incidence. Relatively little is known about the genomic features of African H. pylori strains compared to other populations of strains. In this study, we first analyzed the genomes of …

Limb remote ischemic preconditioning (RIPC) is an effective means of protection against ischemia/reperfusion (IR)-induced injury to multiple organs. Many studies are focused on identifying endocrine mechanisms that underlie the cross-talk between muscle and RIPC-mediated organ protection. We report that RIPC releases irisin, a myokine derived from the extracellular portion of fibronectin domain-containing 5 protein (FNDC5) in skeletal muscle, to protect against injury to the lung. Human patients with neonatal respiratory distress syndrome show reduced concentrations of irisin in the serum and increased irisin concentrations in the bronchoalveolar lavage fluid, suggesting transfer of irisin from circulation to the lung under physiologic …

Quantifying Effectiveness Of Streambank Stabilization Practices On Cedar River, Nebraska, Naisargi Dave, Aaron R. Mittelstet

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Excessive sediment is a major pollutant to surface waters worldwide. In some watersheds, streambanks are a significant source of this sediment, leading to the expenditure of billions of dollars in stabilization projects. Although costly streambank stabilization projects have been implemented worldwide, long-term monitoring to quantify their success is lacking. There is a critical need to document the long-term success of streambank restoration projects. The objectives of this research were to (1) quantify streambank retreat before and after the stabilization of 18 streambanks on the Cedar River in North Central Nebraska, USA; (2) assess the impact of a large flood event; …
