In-Field Labeling Of Western Corn Rootworm Adults (Coleoptera: Chrysomelidae) With Rubidium, Timothy M. Nowatzki, Bradley Niimi, Kelli J. Warren, Sean Putnam, Lance J. Meinke, David C. Gosselin, F. Edwin Harvey, Thomas E. Hunt, Blair D. Siegfried

Department of Entomology: Faculty Publications

Field and laboratory studies were conducted in 2000 and 2001 to determine the feasibility of mass marking western corn rootworm adults, Diabrotica virgifera virgifera LeConte, with RbCl in the field. Results showed that application of rubidium (Rb) in solution to both the soil (1 g Rb/plant) and whorl (1 g Rb/plant) of corn plants was optimal for labeling western corn rootworm adults during larval development. Development of larvae on Rb-enriched corn with this technique did not significantly influence adult dry weight or survival. Rb was also highly mobile in the plant. Application of Rb to both the soil and the …

Characterization Of General Esterases From Methyl Parathion-Resistant And -Susceptible Populations Of Western Corn Rootworm (Coleoptera: Chrysomelidae), Xuguo Zhou, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

A consistent correlation between elevated esterase activity and methyl parathion resistance among Nebraska western corn rootworm, Diabrotica virgifera virgifera LeConte, populations has previously been documented. Characterization of general esterase activity using naphtholic esters as model substrates indicated that differences between resistant and susceptible strains could be maximized by optimizing assay conditions. The optimal conditions identified here were similar to those reported for other insect species. The majority of general esterase activity was found in the cytosolic fractions of resistant populations, whereas the activity was more evenly distributed between cytosolic and mitochondrial/nuclear fractions in the susceptible population. General esterase activity was …

Chinch Bug-Resistant Buffalograss: An Investigation Of Tolerance, Antixenosis, And Antibiosis, Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan, Linda J. Young, Kit Lee

Department of Entomology: Faculty Publications

Choice and no-choice studies were conducted to determine the categories (antibiosis, antixenosis, and tolerance) of resistance of four buffalograsses (NE91-118, ‘Bonnie Brae’, ‘Cody’, and ‘Tatanka’) previously identified as resistant to the western chinch bug, Blissus occiduus Barber. Antibiosis studies found no significant differences in western chinch bug fecundity, nymphal development, or survival among the resistant and susceptible buffalograsses. Tolerance studies indicated that NE91-118, Cody, and Tatanka exhibited moderate-to-high levels of tolerance based on western chinch bug damage ratings and plant height, whereas Bonnie Brae exhibited moderate-to-low levels of tolerance. Choice studies indicated the presence of antixenosis in NE91-118, whereas Cody …

A Case For Taxonomic Recognition Of The Taxon Enodia Anthedon Borealis A. H. Clark (Satyridae), Alex Grkovich, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

Clark (1936) described the taxa anthedon and borealis both as new subspecies of Enodia portlandia (Fabricius, 1781). Clark described borealis as the northernmost phenotypically different taxon in this group. Anthedon later became recognized as a distinct species with borealis as a subspecies of it. Masters (1971) characterized E. anthedon borealis as displaying several subtle phenotypic differences from nominotypical anthedon and also noted significant differences in behavior and habitat and reinforced the continued recognition of borealis as a valid subspecies. However, a number of publications after 1971 generally failed to recognize subspecific status for borealis, either ignoring borealis entirely …

A Taxonomic Review Of Chlosyne Ismeria With Description Of A New Subspecies From The Southern Appalachian Mountains, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The taxon Boisduval and Le Conte described in 1833 as Melitaea ismeria is examined as a historical entity and confirmed as a sister subspecies of the taxon Chlosyne ismeria nycteis. The ismeria populations in the southern Appalachian mountains (United States) are described as a new subspecies: Chlosyne ismeria obsoleta. In facies, this new subspecies is most similar to the western subspecies Chlosyne ismeria drusius in that it is dark and contrasting in its dorsal markings. It is known to range from the mountain region of extreme northern Georgia north in the Appalachians to near southwestern Virginia, United States. …

Research On The Genetics Of Screwworms In Lincoln, Nebraska, Steven Skoda, Dennis Berkebile, Margaret Allen

Department of Entomology: Faculty Publications

The success of the screwworm eradication program - these pests have been eliminated from the North American continent to Panama - has been facilitated by insightful research. The recent research on screwworms by ARS scientists at Lincoln, NE has concentrated on 1) discovering molecular markers useful in population genetics and population identification; 2) genetic research useful in developing a genetic sexing strain (males-only) in screwworms. Amplified fragment length polymorphisms (AFLP) have been studied in screwworms; this technique shows the potential for use in population identification and population genetics. AFLP's will be further explored to determine their utility: a grant proposal …

Book Review: Insecta Coleoptra Chironidae (Huchet, J.-B. 2003), Andrew B. T. Smith

University of Nebraska State Museum: Entomology Papers

The Fauna of Madagascar series has been around for almost 50 years. In that time authors have published on a variety of taxa that occur on this remarkable island. Throughout the history of the series there has been a heavy emphasis on beetles. The latest volume by Jean-Bernard Huchet is no exception. Huchet is an expert on Chironidae (or Chironinae depending on which scarab classification scheme you ascribe to). He is in the process of giving a much-needed taxonomic overhaul to the group. Chironidae are odd-looking scarabs that occur in Africa, Asia (mainly India), and Madagascar and are allied taxonomically …

Ataeniopsis Edistoi (Cartwright) In Florida (Scarabaeidae: Aphodiinae), Paul E. Skelley

University of Nebraska State Museum: Entomology Papers

Ataenius edistoi Cartwright (1974) was described from a series of eight specimens collected near the Edisto River in South Carolina. All were "collected under surface litter on sandy but hard ground along the roadside". According to Cartwright (1974) attempts to collect the species at light at the type locality were not successful, indicating the species does not come to light. The species was transferred to the genus Ataeniopsis Petrovitz by Stebnicka (2003) in a revision of the genus. Ataeniopsis differs from Ataenius Harold in that the apical half of the pygidium in Ataeniopsis is smooth and glabrous, while in Ataenius …

The first and second instars of Lecanodiaspis tingtunensis are described and illustrated. First instars are distinguished from other species of Lecanodiaspis by the arrangement of dorsal 8-shaped pores in six complete longitudinal rows and a partial row in the thoracic region and the number of labial, anal plate, and spiracular setae. Second instars are dimorphic with males possessing well developed 5-segmented legs, dorsal tubular ducts, and long hair-like setae on the venter between the antennae and on the abdominal segments. Females have fewer 8-shaped pores in transverse rows on the dorsum, as well as legs reduced to stubs and only …

An Annotated Checklist Of Wisconsin Mordellidae (Coleoptera), Anneke E. Lisberg, Daniel K. Young

Insecta Mundi

A three-year survey of Wisconsin Mordellidae (Coleoptera) encompassing a compilation of data from literature records and local collections as well as field work including trapping, hand-collecting, and rearing yielded 68 species comprising 14 genera in three tribes. Sixty-three species (92% of Wisconsin fauna) represent new state species records, not previously recorded from the state in the literature. Plant-associations and state-specific temporal and spatial distribution data for larvae and adults are noted as available. Distributional records suggest 16 additional species and one additional genus are likely to occur in Wisconsin.

Genetic Similarity Among Pheromone And Voltinism Races Of Ostrinia Nubilalis (Hubner) (Lepidoptera: Crambidae), P. C. R. G. Marcon, David B. Taylor, C. E. Mason, R. L. Hellmich, Blair Siegfried

Department of Entomology: Faculty Publications

The genetic variability of seven European corn borer populations, Ostrinia nubilalis, from North America and Europe was assessed by polymerase chain reaction- restriction fragment length polymorphism (PCRRFLP) analysis and DNA sequencing. The nuclear ribosomal internal transcribed spacer 1 (ITS-1) region (≈ 500 base pair [bp]) and four mitochondrial (mtDNA) regions (1550 bp total) were examined. The smartweed borer, Ostrinia obumbratalis, and south-Western corn borer, Diatraea grandiosella, were used for comparisons. Of 106 restriction sites identified (80 in mtDNA and 26 in ITS-1), none differentiated geographical populations, pheromone races, or voltine ecotypes of the European corn borer. The …
