Evaluation Of Buffalograss Germplasm For Resistance To Blissus Occiduus (Hemiptera: Lygaeidae), Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan, John E. Foster

Department of Entomology: Faculty Publications

Blissus occiduus Barber has emerged as an important insect pest of buffalograss, Buchloe dactyloides (Nuttall) Engelmann, in Nebraska. This research evaluated selected buffalograss germplasm for resistance to B. occiduus. Eleven buffalograss selections were screened for chinch bug resistance in three greenhouse studies and two field evaluations. Based on chinch bug damage, NE91-118, ‘Tatanka’, ‘Bonnie Brae’, and ‘Cody’ were rated highly to moderately resistant. These four buffalograsses exhibited minimal damage, even though all were heavily infested with chinch bugs. NE84-45-3 and ‘378’ were highly susceptible to B. occiduus. Field evaluations confirmed chinch bug resistance ratings under field conditions. NE91-118 …

Dynamic Change In Photosynthetic Pigments And Chlorophyll Degradation Elicited By Cereal Aphid Feeding, Xinzhi Ni, Sharron S. Quisenberry, Tiffany Heng-Moss, John P. Markwell, Leon G. Higley, Frederick P. Baxendale, Gautam Sarath, Robert Klucas

Department of Entomology: Faculty Publications

The concentration of photosynthetic pigments (i.e., chlorophylls a and b, and carotenoids) and chlorophyll degradation enzyme (i.e., chlorophyllase, oxidative bleaching, and Mg-dechelatase) activities on aphid-damaged and non-damaged regions of the infested leaves were determined with two infestation periods (6 and 12 days). Russian wheat aphid [Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae)] feeding caused significant losses of chlorophylls a and b and carotenoids in the damaged regions. However, bird cherry-oat aphid [Rhopalosiphum padi (L.) (Hemiptera: Aphididae)] feeding did not, except a significantly lower level of carotenoids was observed in the damaged regions from the short-infestation (6-day) samples. Interestingly, the non-damaged …

Eicosanoids Mediate Manduca Sexta Cellular Response To The Fungal Pathogen Beauveria Bassiana: A Role For The Lipoxygenase Pathway, Jeffrey C. Lord, Sheri Anderson, David W. Stanley

Department of Entomology: Faculty Publications

Many studies have documented the involvement of eicosanoids in insect cellular immune responses to bacteria. The use of the fungal pathogen Beauveria bassiana as a nodulation elicitor, with inhibition of phospholipase A2 by dexamethasone, extends the principle to fungi. This study also provides the first evidence of involvement of the lipoxygenase (LOX) pathway rather than the cyclooxygenase (COX) pathway in synthesis of the nodulation mediating eicosanoid(s). The LOX product, 5(S)- hydroperoxyeicosa-6E,8Z,11Z,14Z-tetraenoic acid (5-HPETE), substantially reversed nodulation inhibition caused by dexamethasone and the LOX inhibitors, caffeic acid and esculetin. The COX product, prostaglandin H₂ (PGH₂), did not reverse …

In Vivo And In Vitro Metabolism Of Fi Pronil By Larvae Of The European Corn Borer Ostrinia Nubilalis, Eric W. Durham, Blair D. Siegfried, Michael E. Scharf

Department of Entomology: Faculty Publications

In vivo and in vitro metabolism of [₁₄C]fi pronil was examined in a susceptible European corn borer (Ostrinia nubilalis, Hübner) laboratory strain. [₁₄C]Fipronil penetrated the larval integument slowly, with 71.5% of the applied radioactivity recovered from surface rinses 24 h after topical application. Despite this slow penetration, radioactivity was detected in both the excrement and internal organo-soluble fractions. Radioactivity in the internal aqueous fraction and tissue pellet accounted for less than 0.8% of total radioactivity. The in vivo studies suggest that fipronil oxidation to its sulfone metabolite is the major route of metabolic conversion. …

Cryopreservation Of New World Screwworm Embryos, Dennis Berkebile, Roger Leopold, Jan Chirico, Wen Wang

Department of Entomology: Faculty Publications

The following interpretive summary refers to an oral presentation given at the 2002 Annual Meeting of the Livestock Insect's Workers Conference. The New World screwworm, Cochliomyia hominivorax (Coquerel) has been successfully eradicated from the United States, Mexico and Central America. The program involves monitoring infestations and the mass rearing and release of sterile screwworms. In order for the program to be successful, research must be conducted to make the identification and rearing of the insect more efficient. Methods have been developed to distinguish the screwworm from other fly larvae that may be found in animal wounds using Polymerase Chain Reaction …

Transposable Element-Mediated Transgenic Insects In The Screwworm Program, Margaret Allen, Alfred Handler, Dennis Berkebile, Steven Skoda, Philip Scholl

Department of Entomology: Faculty Publications

The following interpretive summary refers to an oral presentation given at the 2002 Annual Meeting of the Livestock Insect Worker's Conference. Transposable element (TE)-mediated transformation of non-drosophilid insects is becoming a viable and robust gene introduction method for many insects of economic and medical importance. Transformation may be used for gene identification and characterization, and for creating strains with genes encoding lethality or sterility. This technology now has been adapted for and applied to the primary screwworm, Cochliomyia hominivorax (Coquerel). Using a piggyBac TE system, a green fluorescent marker gene has been introduced to the germ line of a laboratory …

Pterourus Appalachiensis (Papilionidae: Papilioninae), A New Swallowtail Butterfly From The Appalachian Region Of The United States, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new univoltine species of Tiger Swallowtail, Pterourus appalachiensis, is described from the southern Appalachian Mountain region of the eastern United States. This distinct swallowtail has remained unrecognized by lepidopterists since the description of its sympatric congener Pterourus glaucus (Linnaeus) in 1758. Historical accounts of Tiger Swallowtails from this region pertain specifically to glaucus and cannot be attributed to this new species. Morphology, voltinism, phenology, distribution, and behavioral traits indicate species level status of appalachiensis. Although appalachiensis shares several phenotypic characters with the recently elevated species canadensis (Rothschild & Jordan), preliminary mitochondrial DNA analysis indicates that appalachiensis is …

Insects And The Native Vegetation Of Nebraska, Brett C. Ratcliffe, Paul C. Hammond

University of Nebraska State Museum: Entomology Papers

The principal plant biomes in Nebraska are briefly reviewed. The relationships of insects, particularly scarab beetles and butterflies, to these biomes are discussed, especially as it relates to their distributions. Human-induced alteration of habitat has significantly influenced the present distributions of both plants and insects relative to their historical distributions at the time of Euro-american colonization of Nebraska in the mid-1800s. Examples of range expansion or contraction are presented for exemplar taxa of scarab beetles and butterflies

Case 3237: Leucopelaea Albescens Bates, 1891 (Insecta, Coleoptera): Proposed Validation Of The Lectotype Designation, Andrew Smith

University of Nebraska State Museum: Entomology Papers

The purpose of this application is to validate the lectotype designation of Leucopelaea albescens Bates, 1891 under Article 86.1.2 of the Code. The nominal species has very recently been considered a junior synonym of Platycoelia lutescens Blanchard, 1851, the name for a scarab beetle (family SCARABAEIDAE) from the Andes in Ecuador, Peru and southern Colombia. The lectotype designation was made under the provisions of the third (1985) edition of the Code in a paper that was accepted for publication in November 1999. However, the paper was not published until May 2000, after the fourth (1999) edition of the Code had …

Using Inert Dusts To Detect And Assess Varroa Infestations In Honey Bee Colonies, P. A. Macedo, J. Wu, Marion D. Ellis

Department of Entomology: Faculty Publications

Detection and assessment of varroa infestations in honey bee colonies are important for successful beekeeping. We examined the use of inert dusts to dislodge mites from adult honey bees that were isolated from their nest. Six dusts (powdered sugar, fine sugar, wheat flour, talcum powder, corn starch and baking soda) were evaluated for their ability to dislodge mites from adult bees collected in jars. We obtained the highest recovery rate with powdered sugar (92.9 ± 5.5%) and talcum powder (84.0 ± 5.6%). We also examined mite survival after recovery with inert dusts and compared it to mite survival after recovery …

Review Of The Genus Acrobolbia With Remarks On Its Classification, And A Key To The World Genera Of Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae), Mary Liz Jameson, Brett C. Ratcliffe, Vladislav Maly

University of Nebraska State Museum: Entomology Papers

The monotypic South American scarab genus Acrobolbia Ohaus, 1912 is reviewed and transferred to the tribe Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae). It was formerly placed in the subtribe Acrobolbiina (Rutelinae: Rutelini) or subtribe Oryctomorphina (Dynastinae: Pentodontini), depending on the author. We discuss characters that warrant transfer, redescribe the genus (including the first description of a female), and briefly discuss natural history of A. macrophylla Ohaus, 1912. We include a key to males and females of all 14 genera of Cyclocephalini.

Observations On Possible Myrmecophily In Stephanucha Pilipennis Kraatz (Coleoptera: Scarabaeidae: Cetoniinae) In Western Nebraska, M. J. Paulsen

University of Nebraska State Museum: Entomology Papers

Little has been published on the life history of the five currently recognized species of Stephanucha Burmeister. Skelley (1991) published the most thorough treatment to date for S. thoracica Casey (recently synonymized with S. areata (F.) by Harpootlian 2001). Skelley located larvae in the mounds of the pocket gopher, Geomys pinetus Rafnesque, in Florida and was the first to describe an immature stage for the genus. Published accounts of Stephanucha species biology are consistent with respect to spring emergence, presence in sandy habitats, and a potential lack of adult feeding or liquid feeding (Lago et ul. 1979; Skelley 1991). Skelley …
