Synthesis Of The Four Stereoisomers Of 7-Acetoxy-15-Methylnonacosane, A Component Of The Female Sex Phermone Of The Screwworm Fly, Cocliomyia Hominivorax), Kenji Mori, Takashi Ohtaki, Hiroshi Ohrui, Dennis Berkebile, David A. Carlson

Department of Entomology: Faculty Publications

The four stereoisomers of 7-acetoxy-15-methylnonacosane (1), a component of the female sex pheromone of the New World screwworm fly (Cocliomyia hominivorax) were synthesized. The stereogenic center at C-15 of 1 originated from that of the enantiomers of citronellal, and that at C-7 was generated by lipase-catalyzed asymmetric acetylation of (3RS,11R)- and (3RS,11S)-17-methyl-1-trimethylsilylpentacos-1-yn-3-ol (13). Three of the stereoisomers of 1 showed equivalent good pheromone activity, while the activity of (7R,15R)-1 was weak.

A Taxonomic Examination Of Harkenclenus Titus (Lycaenidae: Theclinae) In The Eastern United States: Recognition And Resolution Of Taxonomic Problems By The Delineation Of Old Names, Naming Of A Long Recongnized (But Heretofore Undescribed) Subspecies, And Description Of A Wide Ranging New Subspecies, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Harkenclenus is retained per dos Passos 1970 as a genus distinct from Satyrium. The names titus and mopsus have long been considered to apply to two subspecies. These are demonstrated to be synonymous as both names are based on southeastern United States populations. The holotype of titus (Natural History Museum London) is examined and its type locality established as Screven County, Georgia, United States. A neotype is established for the synonymic name mopsus, type locality, Screven County, Georgia, United States. This leaves the long recognized northern subspecies without a name; it is described as new subspecies Harkenclenus titus …

A New Sampling Protocol For The Endangered American Burying Beetle, Nicrophorus Americanus Olivier (Coleoptera: Silphidae), Jon C. Bedick, Brett C. Ratcliffe, Leon G. Higley

University of Nebraska State Museum: Entomology Papers

The endangered American burying beetle, Nicrophorus americanus Olivier, presently occurs in small and widely scattered areas on the periphery of its former range. As part of the recovery plan for this insect implemented by the U.S. Fish and Wildlife Service (USFWS), we conducted surveys in Nebraska to ascertain its presence. Additionally, we examined various trapping methods and procedures in the course of our survey work. We compared the effectiveness of different trap designs, trap placement, timing of trapping, types and amounts of bait, and monitoring traps. We also developed methods to reduce beetle mortality in traps. Our work offers more …

Comments On The Proposed Precedence Of Bolboceras Kirby, 1819 (July) (Insecta, Coleoptera) Over Odonteus Samouelle, 1819 (June), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

(Case 3097; see BZN 59: 246-248, 280-281; 60: 303-311)

I support the application to use Bolboceras Kirby, 1819 (July) instead of Odonteus Samouelle 1819 (June) because of prevailing usage of the name Bolboceras. The name Odonteus has not been used since it was first proposed except by Krell in 1990, who suggested that Odonteus should be used since it had priority. To do so, however, would not only destabilize the nomenclature for the often cited genus name Bolboceras, but it would also decrease the flow of information that is normally associated with the name Bolboceras. Moreover, Bolboceras …

Piggybac Transformation Of The New World Screwworm, Cochliomyia Hominivorax, Produces Multiple Distinct Mutant Strains, M.L. Allen, A.M. Handler, Dennis Berkebile, S.R. Skoda

Department of Entomology: Faculty Publications

Sterile insect technique (SIT) programs are designed to eradicate pest species by releasing mass-reared, sterile insects into an infested area. The first major implementation of SIT was the New World Screwworm Eradication Program, which successfully eliminated the New World screwworm (NWS), Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), from the Continental US, Mexico and much of Central America. Ionizing radiation is currently used for sterilization, but transgenic insect techniques could replace this method, providing a safer, more cost-effective alternative. Genetic transformation methods have been demonstrated in NWS, and verified by Southern blot hybridization, PCR and sequencing of element insertion junctions. A lethal …

Synthesis Of The Four Stereoisomers Of 6-Acetoxy-19-Methylnonacosane, The Most Potent Component Of The Female Sex Pheromone Of The New World Screwworm Fly, With Special Emphasis On Partial Racemization In The Course Of Catalytic Hydrogenation, Kenji Mori, Takashi Ohtaki, Hiroshi Ohrui, Dennis Berkebile, David A. Carlson

Department of Entomology: Faculty Publications

Starting from the enantiomers of citronellal and 1-octyn-3- ol, all four stereoisomers of 6-acetoxy-19-methylnonacosane were synthesized with sufficiently high stereochemical purities (more than 90% ee at C-6; about 97% ee at C-19) for their biological testing as the female sex pheromone of the screwworm fly (Cochliomyia hominivorax). All four isomers showed strong pheromone activity even at 1 μg, and no significant difference was observed in their potency. Adams’ platinum oxide was found to cause partial racemization of enantiomerically pure secondary propargylic alcohols in the course of their catalytic hydrogenation to saturated and secondary alcohols, while palladium-charcoal was less …

Fitness Characteristics Of Transgenic Strains Of Cochliomyia Hominivorax, The New World Screwworm, Margaret Allen, Dennis Berkebile, Steven Skoda

Department of Entomology: Faculty Publications

Sterile insect technique (SIT) programs are designed to eradicate pest species by release of mass-reared, sterile insects into an infested area. The first large-scale implementation of SIT was the New World Screwworm Eradication Program, which successfully eliminated the New World screwworm (NWS), Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) from the Continental US, Mexico, and most of Central America. Ionizing radiation is currently used for sterilization, but transgenic insect techniques could hypothetically replace this method, providing a safer, more cost-effective alternative. Genetic transformation methods have recently been demonstrated in NWS. Some key issues involved in mass release of sterile insects revolve around …

Partial Purification And Characterization Of A Methyl-Parathion Resistance-Associated General Esterase In Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae), Xuguo Zhou, Michael E. Scharf, Gautam Sarath, Lance J. Meinke, Laurence D. Chandler, Blair Siegfried

Department of Entomology: Faculty Publications

Increased hydrolytic metabolism of organophosphate insecticides has been associated with resistance among Nebraska western corn rootworm populations. In this study, resistance-associated esterases were partially purified by differential centrifugation, ion exchange, and hydroxyapatite column chromatography, with a final purification factor of 100-fold and recovery of approximately 10%. Kinetic analysis of the partially purified enzyme indicated that the K_m of the group II esterases was identical for the two populations, although V_max was consistently threefold higher in the resistant population. A putative esterase, DvvII, was further purified to homogeneity by preparative polyacrylamide gel electrophoresis. DvvII is a monomer with a …

A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer

University of Nebraska State Museum: Entomology Papers

A new subspecies of Cicindela nevadica LeConte, Cicindela nevadica makosika Spomer, is described from the South Dakota Badlands. Geographically, the population occurs at the periphery of the range of C. nevadica knausii Leng. However, this new population is geographically isolated from the nearest C. n. knausii populations, which occur ca. 100 air miles north and over 100 air miles south. Phenotypically, C. n. makosika appears most similar to C. n. tubensis Cazier from northeast Arizona. A possible threat to this population is habitat destruction by cattle.

A New Species Of Nanodacna Clarke (Lepidoptera: Elachistldae: Agonoxeninae) Feeding On The Seeds Of Austrocedrus Chilensis (Cupressaceae) In Andean Argentina, Jean-Francois Landry, David Adamski

USDA Systematic Entomology Laboratory

Charaders of the adult, larva, and pupa of Nanodacna allstrocedrella Landry & Adamski, new species, are described and illustrated. The seed-feeding larvae cause damage to Andean Cedar, cipres de la cordillera [Austrocedrus chilcnsis (D. Don.) Fl. & Bout., Cupressaceae] in Chubut Province, Argentina. The species is compared to other species of Nanodacna and to species of Hornoeoprepes Walsingham from the Neotropics. Criteria for its inclusion in Nanodacna and the phylogenetic Significance of characters of immature stages for relationships within the Agonoxeninae are discussed.

Sunflower Beetle (Coleoptera: Chrysomelidae): Pattern Of Larval Distribution And Parasitism In Cultivated Sunflower Fields, Gary J. Brewer, Laurence D. Charlet

Department of Entomology: Faculty Publications

The sunflower beetle, Zygogramma exclamationis (Fabricius), is a major pest of commercial sunflower, Helianthus annuus L. (Asteraceae), in the Plains area of central North America. Although an economic injury level for the sunflower beetle has been determined, in-field distributions of the larvae and their natural enemies have not been described. Over a three year period, fields were sampled for sunflower beetle larvae and for larvae of the endoparasitoid, Myiopharus macellus (Reinhard). Sunflower beetle larvae were generally found to have aggregated distributions. Knowledge of the distribution pattern will allow the development of more efficient sunflower beetle sampling protocols. Parasitism rates of …

Mammals Of Carlsbad Caverns National Park, New Mexico, Kenneth N. Geluso, Keith Geluso

Bulletin of the University of Nebraska State Museum (1924–2023)

Carlsbad Cavern was established as a national park on 14 May 1930, after being designated as a national monument for nearly seven years. The park is located in southeastern New Mexico, and today it encompasses 189.3 km² (73.1 mi²). Eighty-eight percent of the park lies in the rugged Guadalupe Mountains, while 12% is located on relatively flat land along the base of the mountains. The park contains a variety of habitats ranging from desert scrub at the lowest elevations to coniferous woodlands on the highest summits. Five months after Carlsbad Cavern was declared a national monument, Vernon …

The Bacterium Xenorhabdus Nematophila Inhibits Phospholipases A2 From Insect, Prokaryote, And Vertebrate Sources, Youngjin Park, Yonggyun Kim, David Stanley

Department of Entomology: Faculty Publications

The bacterium Xenorhabdus nematophila is a virulent insect pathogen. Part of its pathogenicity is due to impairing cellular immunity by blocking biosynthesis of eicosanoids, the major recognized signal transduction system in insect cellular immunity. X. nematophila inhibits the first step in eicosanoid biosynthesis, phospholipase A₂ (PLA₂). Here we report that the bacterium inhibits PLA₂ from two insect immune tissues, hemocytes and fat body, as well as PLA_2s selected to represent a wide range of organisms, including prokaryotes, insects, reptiles, and mammals. Our finding on a bacterial in-hibitor of PLA₂ activity contributes new insight into …

Lipopolysaccharide Evokes Microaggregation Reactions In Hemocytes Isolated From Tobacco Hornworms, Manduca Sexta, Jon S. Miller, David W. Stanley

Department of Entomology: Faculty Publications

Insect cellular immune reactions to bacterial infection include nodule formation. Eicosanoids mediate several cellular actions in the nodulation process, including formation of hemocyte microaggregates, an early step. In previous work, we reported that isolated hemocytes produce and secrete eicosanoids that influence hemocyte behavior in response to bacterial challenge. We also reported that microaggregate formation in response to challenge was mediated by prostaglandins (PGs), but not by products of the lipoxygenase (LOX) pathways. In this paper we describe experiments designed to test the idea that exposing isolated hemocytes to lipopolysaccharide (LPS) evokes formation of hemocyte microaggregates and this cellular action is …

Atrazine Induction Of A Family 4 Cytochrome P450 Gene In Chironomus Tentans (Diptera: Chironomidae), Diana K. Londono, Blair D. Siegfried, Michael J. Lydy

Department of Entomology: Faculty Publications

Cytochrome P450-dependent microsomal monooxygenase (P450) activity was measured in control and atrazine-exposed third instar midge larvae, Chironomus tentans. Significantly elevated O-demethylase activity was observed in gut homogenates taken from midges exposed to atrazine concentrations from 1 to 10 ppm for 90 h. No significant induction was observed at atrazine concentrations below 1 ppm. A region of a cytochrome P450 family 4 gene was amplified and sequenced from C. tentans larvae. Alignments of inferred amino acid sequences with other insect CYP4 gene homologues indicate a high degree of similarity. Northern blot analysis employing the CYP4 gene fragment as a …

Within-Field Distribution Of The Sunflower Midge (Diptera: Cecidomyiidae), E. W. Hodgson, I. V. Macrae, Gary J. Brewer

Department of Entomology: Faculty Publications

The sunßower midge, Contarinia schulzi Gagne (Diptera: Cecidomyiidae), is a pest of cultivated sunflower (Helianthus annuus L.). Larval feeding can cause damage and yield loss to the sunflower head. Adult emergence is extended and larvae are well protected in the sunflower receptacle, making chemical control methods difficult and expensive. Sunflower midge enter sunflower fields at the edges but fieldwide distributions occur, although the dynamics are not fully understood. Two commercial fields in 1999 and one field in 2000 were systematically sampled by dividing each field into fixed sample points. Mean egg and larval densities from each sample point were …
