The Role Of Rapgap1 In Sxl Activation In Drosophila Melanogaster, Katherine M. Barnes

Lewis Honors College Capstone Collection

The master switch of the sexual differentiation and dosage compensation pathway in Drosophila is the sex lethal gene, Sxl. The early promoter, SxlPe, is activated in females, resulting in female-specific splicing of later transcripts (notably the late Sxl transcript SxlPm), while inactive in males. Chromatin immunoprecipitation (ChIP) assays have previously shown association of two conventionally heterochromatin-localized proteins, HOAP and HP1, at SxlPe, and in situ hybridization as well as RT-PCR assays have confirmed a repressive role for HOAP and both repressive and activating roles for HP1. The mechanism for the activity shift of HP1 is currently unknown. Deletions in the …

Pyrosequencing The Midgut Transcriptome Of The Banana Weevil Cosmopolites Sordidus (Germar) (Coleoptera: Curculionidae) Reveals Multiple Protease-Like Transcripts, Arnubio Valencia, Haichuan Wang, Alberto Sotomayor, Manuel Aristizabal, Jorge W. Arboleda, Seong-Il Eyun, Daniel D. Noriega, Blair D. Siegfried

Department of Entomology: Faculty Publications

The banana weevil Cosmopolites sordidus is an important and serious insect pest in most banana and plantain-growing areas of the world. In spite of the economic importance of this insect pest very little genomic and transcriptomic information exists for this species. In the present study, we characterized the midgut transcriptome of C. sordidus using massive 454-pyrosequencing. We generated over 590,000 sequencing reads that assembled into 30,840 contigs with more than 400 bp, representing a significant expansion of existing sequences available for this insect pest. Among them, 16,427 contigs contained one or more GO terms. In addition, 15,263 contigs were assigned …

Environmental Parameters Associated With Stable Fly (Diptera: Muscidae) Development At Hay Feeding Sites, Kristina Friesen, Dennis R. Berkebile, Brian Wienhold, Lisa Durso, Jerry Zhu, David B. Taylor

Department of Entomology: Faculty Publications

Substrates composed of hay residues, dung, and urine accumulate around winter hay feeding sites in cattle pastures, providing developmental habitats for stable flies. The objective of this study was to relate physiochemical and microbial properties of these substrates to the presence or absence of stable fly larvae. Properties included pH, temperature, moisture, ammonium concentration, electrical conductivity, and numbers of coliform, fecal coliform, Escherichia coli, and Enterococcus bacteria. Each physiochemical sample was classified as a function of belonging to one of the three 2-m concentric zones radiating from the feeder as well as presence or absence of larvae. In total, …

Rnai As A Management Tool For The Western Corn Rootworm, Diabrotica Virgifera Virgifera, Elane Fishilevich, Ana Maria Vélez, Nicholas P. Storer, Huarong Li, Andrew J. Bowling, Murugesan Rangasamy, Sarah E. Worden, Kenneth E. Narva, Blair D. Siegfried

Department of Entomology: Faculty Publications

The western corn rootworm (WCR), Diabrotica virgifera virgifera, is the most important pest of corn in the US Corn Belt. Economic estimates indicate that costs of control and yield loss associated with WCR damage exceed $US 1 billion annually. Historically, corn rootworm management has been extremely difficult because of its ability to evolve resistance to both chemical insecticides and cultural control practices. Since 2003, the only novel commercialized developments in rootworm management have been transgenic plants expressing Bt insecticidal proteins. Four transgenic insecticidal proteins are currently registered for rootworm management, and field resistance to proteins from the Cry3 family …

Reproductive Potential Of Spodoptera Eridania (Stoll) (Lepidoptera: Noctuidae) In The Laboratory: Effect Of Multiple Couples And The Size, Alexandre Specht, Débora Goulart Montezano, Daniel Ricardo Sosa-Gómez, Silvana L. Vieira De Paula Moraes, Vânia F. Roque-Specht, Neiva M. Barros

Department of Entomology: Faculty Publications

This study aimed to evaluate the effect of keeping three couples in the same cage, and the size of adults emerged from small, medium-sized and large pupae (278.67 mg; 333.20 mg and 381.58 mg, respectively), on the reproductive potential of Spodoptera eridania (Stoll, 1782) adults, under controlled conditions (25 ± 1 °C, 70% RH and 14 hour photophase). We evaluated the survival, number of copulations, fecundity and fertility of the adult females. The survival of females from these different pupal sizes did not differ statistically, but the survival of males from large pupae was statistically shorter than from small pupae. …

The Trichoptera Of Panama Iv. New Records For Caddisflies (Insecta: Trichoptera) From The Republic Of Panama, Brian J. Armitage, Steven C. Harris, Roger J. Blahnik, Robin E. Thomson

Insecta Mundi

The Republic of Panama currently has 300 recorded species of Trichoptera distributed among 14 families. Herein we add 42 new country records for Panama, including one new family (Anomalopsychidae) and three new genera (Anomalopsychidae: Contulma; Hydroptilidae: Byrsopteryx and Cerasmatrichia). The newly recorded caddisfly taxa increase Panama’s total known fauna to 342 species, distributed among 15 families and 50 genera. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate that country’s major watersheds (cuencas).

Corrections To Neotropical Rhinaspis Perty And Plectris Lepeletier And Audinet-Serville (Coleoptera: Scarabaeidae: Melolonthinae) Classifi Cation And Nomenclature, Andrew B. T. Smith

Insecta Mundi

The name Melolontha hypocrita Mannerheim, 1829 has been long unused, even though it is the type species of Hyporhiza Dejean, 1833. I examined the only known specimen from the type series and here designate it as the lectotype. Examination of this lectotype reveals that this species is best placed in the genus Rhinaspis Perty, 1830. Consequently, the genus Hyporhiza Dejean, 1833 is confi rmed as a junior synonym of Rhinaspis. Further, the replacement name Rhinaspis fuhrmanni is proposed for Rhinaspis hypocrita (Blanchard, 1850), a new secondary homonym of Rhinaspis hypocrita (Mannerheim, 1829). A homonymy problem was also discovered and …

New Antlion Records (Neuroptera: Myrmeleontidae) From Paraguay, Olga Petko, Paul Smith, Lionel Stange, Sergio D. Rios

Insecta Mundi

New records of Myrmeleontidae from Paraguay are presented: Dimares elegans (Perty, 1833), Glenurus croesus Banks, 1922, Glenurus penningtoni (Navás, 1918a) and Vella fallax (Rambur, 1842). The total number of species now recorded from the country is fourteen among 11 genera. Specimens of Dimares elegans from east (Cerrado) and west (Chaco) of the Paraguay River are phenotypically distinct; those west of the Paraguay River are assigned to the form “lepida” Navás, 1912. More research is required to understand the taxonomic limits in this genus.
