Exploring Mitigation Options To Reduce Vehicle-Caused Mortality For The Oregon Silverspot Butterfly, Speyeria Zerene Hippolyta, Along Highway 101 At The Siuslaw National Forest, Sara B. Zielin

Environmental Science and Management Professional Master's Project Reports

The Oregon Silverspot Butterfly (OSB), Speyeria zerene hippolyta, is federally listed as "threatened." It historically inhabited coastal regions of Washington, Oregon, and California (USFWS 2001). OSB populations only remain at five sites, four of which are in Oregon; one remaining population is in California, and none exist in Washington state as they have been extirpated (BFCI 2009; USFWS 2001). The site selected for this study was Rock Creek-Big Creek, adjacent to the Siuslaw National Forest. At this site OSB habitat is bisected by Highway 101; butterflies are observed to use both sides of the highway throughout their life cycle. …

Effect Of Seasons And Larval Food Plants On The Quality Of Gonometa Postica Cocoons, Ken O. Fening, Esther N. Kioko, Suresh K. Raina, Jones M. Mueke

All Peer-Reviewed Publications

The effect of food plants [Acacia elatior Brenan, A. tortilis (Forssk.) and A. nilotica (L.) Del.] on the development time of Gonometa postica Walker (Lepidoptera: Lasiocampidae) larvae and the quality of their cocoons was studied in the Imba and Mumoni forests of Mwingi, Eastern Kenya, during the long (March-May) and short (October-December) rainy seasons of 2006 and 2007. Larvae were reared in semi-captivity in net sleeves attached to branches of the plants. The period between hatching of eggs and spinning of cocoons, as well as their weight, as determinants of cocoon quality were recorded. In addition, collections of cocoons from …

Ecological Interactions Between Spiders And The Purple Pitcher Plant, Sarracenia Purpurea, Marc Aaron Milne

Biological Sciences Theses & Dissertations

Spiders and harvestmen are commonly captured by or reside upon the carnivorous purple pitcher plant, Sarracenia purpurea. Although spiders and harvestmen are often known to be prey of S. purpurea, other ecological interactions between these arthropods and the plant are poorly understood. Studies were undertaken at three pitcher plant populations, two in Virginia and one in North Carolina, to assess the ecological relationships between spiders and harvestmen and S. purpurea. Multiple plots containing pitcher plants (treatment) and plots lacking pitcher plants (control) were created at these locations. Spiders and harvestmen were collected through five different techniques. Spatial, …

Observations On Anthocharis Julia Browningi And Anthocharis Thoosa Thoosa Including Tension Zones Near Nephi, Juab County, Utah, Todd Stout

The Taxonomic Report of the International Lepidoptera Survey

Two visibly distinct taxa of the sara orangetip fly sympatrically and synchronically in a zone northeast of Nephi, Juab County, Utah. This paper discusses how these two taxa interact based upon six character sets—adult phenotype, adult male behavior, distribution, habitat, larval coloration, and pupal shape.

Molecular Evidence For A Functional Ecdysone Signaling System In Brugia Malayi, George Tzertzinis, Ana L. Egaña, Subba Reddy Palli, Marc Robinson-Rechavi, Chris R. Gissendanner, Canhui Liu, Thomas R. Unnasch, Claude V. Maina

Entomology Faculty Publications

BACKGROUND: Filarial nematodes, including Brugia malayi, the causative agent of lymphatic filariasis, undergo molting in both arthropod and mammalian hosts to complete their life cycles. An understanding of how these parasites cross developmental checkpoints may reveal potential targets for intervention. Pharmacological evidence suggests that ecdysteroids play a role in parasitic nematode molting and fertility although their specific function remains unknown. In insects, ecdysone triggers molting through the activation of the ecdysone receptor: a heterodimer of EcR (ecdysone receptor) and USP (Ultraspiracle).

METHODS AND FINDINGS: We report the cloning and characterization of a B. malayi EcR homologue (Bma-EcR). Bma-EcR dimerizes with …

Title

Flight Periods of California Butterflies for “Resident Species,” Subspecies and Most Strays to the State (2010)

Authors

Kenneth E. Davenport, Ray E. Stanford and Robert L. Langston

Abstract

Normal flight periods and early/late records for resident species, subspecies and regular strays of butterflies of California are presented below.. Many subspecies or populations in the state are distinctive and may prove to merit species recognition by specialists in the future.

New Species Of Cerambycinae (Coleoptera, Cerambycidae) From South America, Maria Helena M. Galileo, Ubirajara R. Martins

Insecta Mundi

New species are described in the tribe Piezocerini: Gorybia rondonia sp. nov. from Brazil (Rondônia) and G. bahiensis sp. nov. from Brazil (Bahia); in the tribe Hexoplonini: Calycibidion rubricolle sp. nov. from Brazil (Bahia); in the tribe Ibidionini, Tropidina: Tropidion argentina sp. nov. from Argentina (La Rioja) and T. boliviensis sp. nov. from Bolivia (Santa Cruz); in the tribe Rhinotragini: Ommata (Ommata) albitarsis sp. nov. from Brazil (Rondônia); and in the tribe Rhopalophorini: Cosmisoma viridescens sp. nov. from Brazil (Bahia). To validate the tribal names, Hexoplon Thomson, 1864 and Tropidion Thomson, 1867, are here designated type genera of Hexoplonini and …

Occurrence Of The Milliped, Hiltonius Carpinus Carpinus Chamberlin, 1943 (Spirobolida: Spirobolidae), In The United States And New Records From Mexico, Rowland M. Shelley

Insecta Mundi

Hiltonius carpinus carpinus Chamberlin, 1943 (Spirobolida: Spirobolidae), is authoritatively recorded from the United States for the first time; it is known only from southern/southeastern Arizona but should be expected in adjoining counties of New Mexico. The northernmost locality is the Pinaleno Mountains, Graham County, and its distribution extends to southern Mexico; the other subspecies, H. c. vulcan (Chamberlin, 1953), occurs in Guatemala. The range of H. c. carpinus includes the type locality of the enigmatic H. fossulifer (Pocock, 1908), lending credence to prior suggestions that the names are synonymous. Three new Mexican states – Durango, Jalisco, and Nuevo León – …

The Anthonomus Juniperinus Group, With Descriptions Of Two New Species (Coleoptera: Curculionidae), Wayne E. Clark, Horace R. Burke

Insecta Mundi

The Anthonomus juniperinus (Sanborn) species group is defined and two new species, Anthonomus sanborni, new species, and A. rileyi new species, from the United States are described, keyed and illustrated. The three species of the group are associated with the plant genus Juniperus and the larvae of A. juniperinus are known to develop in fungal galls of Gymnosporangium spp. as well as fruits of the Eastern redcedar, Juniperus virginiana L. The biology of the group and its taxonomic relationships to other species of Anthonomus Germar are also discussed.

A table with the approximate longitudes and latitudes of all but one locality listed is provided.

Diversity And Distribution Of The Scarab Beetle Tribe Phanaeini In The Northern States Of The Brazilian Northeast (Coleoptera: Scarabaeidae: Scarabaeinae), Conrad P. D. T. Gillett, Michael P. T. Gillett, James E. D. T. Gillett, Fernando Z. Vaz-De-Mello

Insecta Mundi

The fauna of Phanaeini of the northeast of Brazil was investigated through fieldwork in the States of Ceará, Maranhão and Piauí, and through study of preserved material from other states. Seven species of Phanaeini are newly recorded from these three states. Of these, two species are also new records for the northeast region: Phanaeus melibaeus Blanchard and an unidentified Dendropaemon Perty species. A total of 13 new state records are given for eight of the 15 species of Phanaeini recorded from the northeast to date, including three new state genus records. A key is provided for identification of all species. …

Molecular Diagnosis Of A Previously Unreported Predator-Prey Association In Coffee: Karnyothrips Flavipes Jones (Thysanoptera: Phlaeothripidae) Predation On The Coffee Berry Borer, Juliana Jaramillo, Eric G. Chapman, Fernando E. Vega, James D. Harwood

All Peer-Reviewed Publications

The coffee berry borer, Hypothenemus hampei, is the most important pest of coffee throughout the world, causing losses estimated at US 500 million/year. The thrips Karnyothrips flavipes was observed for the first time feeding on immature stages of H. hampei in April 2008 from samples collected in the Kisii area of Western Kenya. Since the trophic interactions between H. hampei and K. flavipes are carried out entirely within the coffee berry, and because thrips feed by liquid ingestion, we used molecular gut-content analysis to confirm the potential role of K. flavipes as a predator of H. hampei in an organic …

Prospects For The Development Of Odour Baits To Control The Tsetse Flies Glossina Tachinoidesand G. Palpalis S.L., J. B. Rayaisse, I. Tirados, D. Kaba, S. Y. Dewhirst, J. G. Logan, A. Diarrassouba, E. Salou, M. O. Omolo, P. Solano, M. J. Lehane, J. A. Pickett, G. A. Vale, S. J. Torr, J. Esterhuizen

All Peer-Reviewed Publications

Field studies were done of the responses of Glossina palpalis palpalis in Côte d'Ivoire, and G. p. gambiensis and G. tachinoides in Burkina Faso, to odours from humans, cattle and pigs. Responses were measured either by baiting (1.) biconical traps or (2.) electrocuting black targets with natural host odours. The catch of G. tachinoides from traps was significantly enhanced (∼5x) by odour from cattle but not humans. In contrast, catches from electric targets showed inconsistent results. For G. p. gambiensis both human and cattle odour increased (>2x) the trap catch significantly but not the catch from electric targets. For …

Mitochondrial Phylogenomics Of The Bivalvia (Mollusca): Searching For The Origin And Mitogenomic Correlates Of Doubly Uniparental Inheritance Of Mtdna, Hélène Doucet-Beaupré, Sophie Breton, Eric G. Chapman, Pierre U. Blier, Arthur E. Bogan, Donald T. Stewart, Walter R. Hoeh

Entomology Faculty Publications

BACKGROUND: Doubly uniparental inheritance (DUI) is an atypical system of animal mtDNA inheritance found only in some bivalves. Under DUI, maternally (F genome) and paternally (M genome) transmitted mtDNAs yield two distinct gender-associated mtDNA lineages. The oldest distinct M and F genomes are found in freshwater mussels (order Unionoida). Comparative analyses of unionoid mitochondrial genomes and a robust phylogenetic framework are necessary to elucidate the origin, function and molecular evolutionary consequences of DUI. Herein, F and M genomes from three unionoid species, Venustaconcha ellipsiformis, Pyganodon grandis and Quadrula quadrula have been sequenced. Comparative genomic analyses were carried out on these …
