Amplification And Methylation Of An Esterase Gene Associated With Insecticide-Resistance In Greenbugs, Schizaphis Graminum (Rondani) (Homoptera: Aphididae), Midori Ono, Jeffrey J. Swanson, Linda M. Field, Alan L. Devonshire, Blair D. Siegfried

Department of Entomology: Faculty Publications

The greenbug aphid, Schizaphis graminum (Rondani) has developed resistance to organophosphorus insecticides by the over-production of esterases that have been classified as Type I and Type II. The first twenty N-terminal amino acids of the Type I esterase were determined and used to design an oligonucleotide, which in conjunction with an active site primer derived from conserved sequences of other insect esterases and two internal primers specific for esterases from another aphid species resulted in a 0.85 kb genomic DNA fragment from resistant greenbugs. This was extended by 5′ RACE which provided approximately 1.2 kb of the 5′ end …

Natural Hyperthermia And Expression Of The Heat Shock Protein Hsp70 Affect Developmental Abnormalities In Drosophila Melanogaster, Stephen P. Roberts, Martin E. Feder

Biological Sciences Faculty Research & Creative Works

We Demonstrate that Natural Heat Stress on Wild Larval Drosophila Melanogaster Results in Severe Developmental Defects in >10% of Eclosing Adults, and that Increased Copy Number of the Gene Encoding the Major Inducible Heat Shock Protein of D. Melanogaster, Hsp70, is Sufficient to Reduce the Incidence of Such Abnormalities. Specifically, Non-Adult D. Melanogaster Inhabiting Necrotic Fruit Experienced Severe, Often Lethal Heat Stress in Natural Settings. Adult Flies Eclosing from Wild Larvae that Had Survived Natural Heat Stress Exhibited Severe Developmental Anomalies of Wing and Abdominal Morphology, Which Should Dramatically Affect Fitness. the Frequency of Developmental Abnormalities Varied Along Two Independent …

Blissus Occiduus (Hemiptera: Lygaeidae): A Chinch Bug Pest New To Buffalograss Turf, Frederick P. Baxendale, Tiffany Heng-Moss, Terrance P. Riordan

Department of Entomology: Faculty Publications

Blissus occiduus Barber, a relatively small chinch bug characterized by conspicuous wing dimorphism, has emerged as an important insect pest of buffalograss, Buchloe dactylnides (Nuttall) Engelmann. It completes 2 generations a year on buffalograss in Nebraska. Overwintered adults become active as early as mid-March. Depending on the season, 1st-generation nymphs can be present from early May through early August, with 1st-generation adults (up to 60% macropterous forms) appearing in mid to late June. Second generation nymphs can be present from early July through fall, with 2nd-generation adults appearing in late August to early September. These predominately brachypterous (>95%) adults …

Oviposition By European Corn Borer (Lepidoptera: Crambidae) In Response To Various Transgenic Corn Events, Richard L. Hellmich, L. S. Higgins, John F. Witkowski, J. E. Campbell, L. C. Lewis

Haskell Agricultural Laboratory (Northeast Research and Extension Center)

Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 experimental event. Results from 3 independent studies are reported, including 3 field-cage experiments with vegetative corn, 2 field-cage experiments with reproductive corn, and 2 field experiments with natural O. nubilalis on reproductive corn. In each case, Bt corn hybrids are compared with their near isogenic hybrids by …

Tissue Polyunsaturated Fatty Acids And A Digestive Phospholipase A 3 In The Primary Screwworm, Cochliomyia Hominivorax, A.R. Nor Aliza, R.L. Rana, Steven R. Skoda, Dennis R. Berkebile, David W. Stanley

Department of Entomology: Faculty Publications

We report on the presence of arachidonic acid in larval and adult tissues of the primary screwworm, Cochliomyia hominivorax and of the secondary screwworm, C. macellaria. Arachidonic acid is present in the phospholipids of whole animal extracts of both species. This fatty acid appears to be accumulated during the larval stages, because proportions of arachidonic acid were higher in adults than in larvae. These insects probably obtain the arachidonic acid from dietary phospholipids. We also report on a phospholipase A2 activity in midgut preparations from third instars of the primary screwworm. Phospholipase A2 is responsible for hydrolyzing fatty acids …

Measurement Of Oxygen Partial Pressure, Its Control During Hypoxia And Hyperoxia, And Its Effect Upon Light Emission In A Bioluminescent Elaterid Larva, G. S. Timmins, C. A. A. Penatti, E. J. H. Bechara, H. M. Swartz

Dartmouth Scholarship

This study investigates the respiratory physiology of bioluminescent larvae of Pyrearinus termitilluminans in relation to their tolerance to hypoxia and hyperoxia and to the supply of oxygen for bioluminescence. The partial pressure of oxygen (P(O2)) was measured within the bioluminescent prothorax by in vivo electron paramagnetic resonance (EPR) oximetry following acclimation of larvae to hypoxic, normoxic and hyperoxic (normobaric) atmospheres and during periods of bioluminescence (during normoxia). The P(O2) in the prothorax during exposure to an external P(O2) of 15.2, 160 and 760 mmHg was 10.3+/-2.6, 134+/-0.9 and 725+/-73 mmHg respectively (mean +/- s.d., N=5; 1 mmHg=0.1333 kPa). Oxygen supply …

Distribution, Ecology, And Population Dynamics Of The American Burying Beetle [Nicrophorus Americanus Olivier (Coleoptera, Silphidae)] In South-Central Nebraska, Usa, Jon C. Bedick, Brett C. Ratcliffe, W. Wyatt Hoback, Leon G. Higley

University of Nebraska State Museum: Entomology Papers

The endangered American burying beetle, Nicrophorus americanus Olivier, was previously widespread throughout eastern North America. In the past century numbers of this beetle have drastically declined and currently remnant populations are known from only six states despite intensive surveying efforts conducted for the last nine years. Efforts aimed at discovering and managing remnant populations have been generally limited by a lack of knowledge concerning N. americanus biology. We used baited pitfall traps to define the range of the Gothenburg, Nebraska, population of N. americanus. Using mark-recapture techniques, we estimate that the annual Gothenburg population consists of more than one …

Acmaeodera Pubiventris Horn (Coleoptera: Buprestidae): A Polytypic Species Or A Superspecies?, Richard L. Wescott

Insecta Mundi

Acmaeodera pubiventris Horn was studied in detail and, without rejecting that it may be a superspecies, I concluded it is a polytypic species comprised of A. p. pubiuentris, A. p. lanata Horn, A. p. yumae Knull-these generally have been considered as full species-and a new subspecies, A. p. panocheae, described herein. It is suggested that A. p. yumae could be a megasubspecies. Detailed comparisons are made, variation is discussed, and biological and distributional data are provided. A. p. lanata is recorded from Mexico (Baja California) for the first time.

Celastrina Idella (Lycaenidae: Polyommatinae): A New Butterfly Species From The Atlantic Coastal Plain, David M. Wright, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

A new species of Polyommatinae, Celastrina idella, is described from the sandy Atlantic coastal plain of the eastern United States. It is presently known to occur from southern New Jersey through Georgia. Celastrina idella larvae have been recorded from four species of Ilex (holly). Celastrina idella is distinguished from sympatric C. ladon and C. neglecta by differences in larval host, flight period, pupal diapause, and adult size and wing characters. In the New Jersey pine barrens the butterfly is univoltine and flies in the spring between the flights of its sympatric congeners.

Hübner’S Helicta, The Forgotten Neonympha: The Recognition And Elevation Of Neonympha Helicta (Nymphalidae: Satyrinae) To Specific Status, The Designation Of Neotypes For N. Helicta And N. Areolatus, The Subspecific Transfer Of Septentrionalis To Helicta And The Description Of A Third Helicta Subspecies From South Florida, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Hübner (1806) based the name Oreas fimbriata helicta on a John Abbot painting of a southeastern United States satyr without a written description. Subsequent lepidopterists have nearly ignored this taxon. Helicta is herein recognized as a valid species–Neonympha helicta. A neotype is designated for helicta from Aiken County, South Carolina and deposited in the Allyn Museum of Entomology Sarasota, Florida. A neotype is also designated for Papilio areolata J.E. Smith, 1797 from Chatham County, Georia and deposited in the Allyn Museum of Entomology. Septentrionalis Davis, 1924 is recognized as the northern United States subspecies of helicta not areolatus …

Mechanisms Of Thermal Stability During Flight In The Honeybee Apis Mellifera, Stephen P. Roberts, Jon F. Harrison

Biological Sciences Faculty Research & Creative Works

Thermoregulation of the Thorax Allows Honeybees (Apis Mellifera) to Maintain the Flight Muscle Temperatures Necessary to Meet the Power Requirements for Flight and to Remain Active Outside the Hive Across a Wide Range of Air Temperatures (T(A)). to Determine the Heat-Exchange Pathways through Which Flying Honeybees Achieve Thermal Stability, We Measured Body Temperatures and Rates of Carbon Dioxide Production and Water Vapor Loss between T(A) Values of 21 and 45°C for Honeybees Flying in a Respirometry Chamber. Body Temperatures Were Not Significantly Affected by Continuous Flight Duration in the Respirometer, indicating that Flying Bees Were at Thermal Equilibrium. Thorax Temperatures …
