Cranberry Girdler, Erin W. Hodgson, Alan H. Roe

All Current Publications

Cranberry girdler, Chrysoteuchia topiaria, can be found throughout the U.S., but is particularly damaging to turfgrass seed production areas in the Pacific Northwest. This insect was first detected in northern and northeastern Utah during the early 1980’s. Larvae prefer cool-season grasses, such as Kentucky bluegrass, bentgrass and fine-leaf fescues. In addition to causing significant damage to turfgrass, it is recorded as a pest of other grasses, cranberry, Douglas fir, and true firs.

Armyworm And Cutworms In Turf, Erin W. Hodgson

All Current Publications

Armyworms and cutworms can be found all over the United States, with at least three species found in Utah. These insects belong to a large group of night-flying moths in the family Noctuidae. Although not new pests to turfgrass, armyworms and cutworms are often ignored, and plant health decline is confused with drought stress, fungal disease, or other insects.

Sod Webworms, Erin W. Hodgson, Alan H. Roe

All Current Publications

The term “sod webworm” refers to an insect complex of more than twenty different grass-infesting species. Adult sod webworms are pyralid moths, but are more commonly referred to as “snout moths” because their mouthparts are projected forward (Fig. 1). Sod webworms are distributed through the U.S., and at least seven different species occur in Utah (Table 1).

Larval Habitats Of Anopheles Gambiae S.S. (Diptera: Culicidae) Influences Vector Competence To Plasmodium Falciparum Parasites, Bernard A. Okech, Louis C. Gouagna, Guiyun Yan, John I. Githure, John C. Beier

All Peer-Reviewed Publications

Background. The origin of highly competent malaria vectors has been linked to productive larval habitats in the field, but there isn't solid quantitative or qualitative data to support it. To test this, the effect of larval habitat soil substrates on larval development time, pupation rates and vector competence of Anopheles gambiae to Plasmodium falciparum were examined. Methods. Soils were collected from active larval habitats with sandy and clay substrates from field sites and their total organic matter estimated. An. gambiae larvae were reared on these soil substrates and the larval development time and pupation rates monitored. The emerging adult mosquitoes …

Yosemite Butterflies (Text), 2nd Edition, Kenneth E. Davenport

The Taxonomic Report of the International Lepidoptera Survey

The author, Kenneth E, Davenport, has collected or observed butterflies extensively in the Yosemite region (at least 90 collecting or observation days) since August 1963. Information for this study began with Davenport obtaining a copy of Garth and Tilden’s 1963 Yosemite Butterflies in 1970. The annual Season Summaries for California published in the News of the Lepidopterists’ Society between 1975 and 2006 have been checked for records. The common English and scientific names used in this publication mostly follow the names used by the International Lepidoptera Survey (TILS) except in a few cases.

The following individuals contributed information: George T. …

The Long Term Effect Of Time-Memory On Forager Honey Bee (Apis Mellifera) Recruitment., Matthew Walter Otto

Electronic Theses and Dissertations

Experiments were performed to determine the influence of the honey bee time-memory on a forager bee's sensitivity to recruitment. Two groups of foragers from one colony were trained to separate food stations at the same restricted time of day for several consecutive days. Feeding then was canceled at one station but continued for four more days at the other. Bees with more days of training at a non-productive source were significantly less likely than foragers with less training to be recruited to an alternative food source presented at the same time of day. Furthermore, the ability of a forager to …

Modeling Of Culicidae Population Capacity Using Remote Sensing, Gis, And Fractal Geometry, Daniel Patrick Johnson

All-Inclusive List of Electronic Theses and Dissertations

A remote sensing and fractal geometric approach is proposed for the surveillance of mosquito population. The spread of vector-borne pathogens is becoming increasingly important with recent discussions of extensive human urbanization and global climate change. To date most studies dealing with mosquito transmitted disease surveyed by remote sensing and Geographic Information Systems have been conducted in tropical homogenous locales. This study approached the issue in a rapidly suburbanizing county in the Midwestern portion of the United States. Adult mosquitoes were trapped over a several year period and the landscape of the surrounding patches analyzed via remote sensing, fractal geometry, and …

A Description Of A New Subspecies Of Lycaena Phlaeas (Lycaenidae: Lycaeninae) From Montana, United States, With A Comparative Study Of Old And New World Populations, Steve Kohler

The Taxonomic Report of the International Lepidoptera Survey

The Palaearctic, Oriental, and Ethiopian Region subspecies of Lycaena phlaeas are briefly discussed. A more detailed account of the North American subspecies is presented, and a new subspecies, L. p. weberi, from the Sweet Grass Hills, Montana is described. The possibility that the eastern United States subspecies hypophlaeas was introduced from the Old World is discussed; however no conclusion can be reached with certainty. The relationship between Old World and New World subspecies of L. phlaeas is discussed. Evidence presented supports the treatment of New World populations as subspecies of L. phlaeas.

Epizootiological Importance Of Glossina Morsitans Submorsitans (Diptera: Glossinidae) (Newstead) In The Ghibe River Valley, Southwest Ethiopia, Merid Negash, Melaku Girma, Emiru Seyoum

All Peer-Reviewed Publications

The epizootiological importance of Glossina morsitans submorsitans in Ghibe River Valley was undertaken from October 2000 to September 2001. The flies were collected using baited monoconical traps. G. m. submorsitans occurred with a mean apparent density of 4.26 ± 0.49 flies/trap/day and the apparent density was characterized by an increase during the wet season and a decrease during the dry season. Among 450 G. m. submorsitans, approximately 5% were found to be infected with trypanosome. Of these infected flies, 76% were female. Nanomonas, Duttonella and Trypanozoon were the three trypanosome subgenera detected and occurred in the proportions of 57.1%, 38.1% …

Yellowjackets, Hornets, And Paper Wasps, Erin Hodgson, Alan Roe

All Current Publications

Social wasps, including yellowjackets, hornets and paper wasps, are common stinging insects in Utah (Figs. 1, 2). The wasps are related to ants and bees, which are also capable of stinging; however, yellowjackets are the most likely to sting.

Mutual Grooming In Cucujoid Beetles (Coleoptera: Silvanidae), Barry D. Valentine

Insecta Mundi

Mutual grooming in two genera of silvanid beetles is described, and appears to be the first report of this behavior in the order Coleoptera. In Uleiota debilis (LeConte), allogrooming recipients were either stationary or moved away during the acts, without solicitation or facilitation. In Nausibius major Zimmermann, allogrooming was much more extensive and the individual being groomed appeared to facilitate the process by immobility or by changes in posture, there were no recognizable sexual overtones, no solicitations, and no avoidance movements. Gregarious behaviors of some other silvanid beetles are reviewed.

Distribution And Biology Of The Ectoparasitic Beetles Leptinillus Validus (Horn) And L. Aplodontiae Ferris Of North America (Coleoptera: Leiodidae: Platypsyllinae), Stewart B. Peck

Insecta Mundi

The distribution and biology of the beetles Leptinillus validus (Horn) and L. aplodontiae Ferris are summarized for North America. The beetles are ectoparasitic on rodents; L. validus on the beaver, Castor canadensis Linnaeus (Castoridae) throughout the northern part of its range, and L. aplodontiae on the mountain beaver, Aplodontia rufa (Rafinesque) (Aplodontidae) in the Pacific Northwest.

A History Of Mole Crickets (Orthoptera: Gryllotalpidae) In Puerto Rico, J. H. Frank, N. E. Vicente, N. C. Leppla

Insecta Mundi

Abstract:
Published claims in 1887-1903 that the mole cricket Neocurtilla hexadactyla (Perty) occurs in Puerto Rico all seem to be derived from a misidentification made by Agustín Stahl, a medical practitioner and collector of natural history objects, published in 1882. That species does not seem now to occur in Puerto Rico and almost certainly never did. However, the opportunity still exists for it to colonize by wind-assisted flight from islands to the southeast just as we believe did the mole cricket Scapteriscus didactylus (Latreille) as an immigrant. Stahl evidently mistook the latter for the former. According to some subsequent authors, …

New And Old Mosquito Records For Extreme Southern Florida (Diptera: Culicidae), Lawrence J. Hribar

Insecta Mundi

New locality records for Culiseta inornata (Williston) are reported from Big Pine Key, Grassy Key, and No Name Key in Monroe County, Florida. Five specimens were collected in dry ice-baited light traps. An old, previously unrecognized record for Anopheles grabhamii Theobald from Miami, Dade County, Florida, is reported based on specimens found in the Florida State Collection of Arthropods.

Primer Registro De Trypoxylon Mexicanum Para La Hispaniola, Antillas Mayores (Hymenoptera: Apoidea: Crabronidae), Julio Genaro

Insecta Mundi

Resumen:
Trypoxylon (Trypargilum) mexicanum (Hymenoptera: Crabronidae) pertenece al grupo albitarse, el cual incluye a las especies mayores del género. Su distribución nativa abarca América Central, desde México hasta Panamá. En este trabajo se menciona por primera vez para la Hispaniola, Antillas. Es difícil imaginarse una especie conspicua como esta sin haber sido detectada anteriormente por algún naturalista o especialista en himenópteros aculeatos, por lo que considero un arribo reciente a la isla. Esta especie pudo haber llegado a través del comercio con América Central, ya que los nidos, hechos de barro, pueden transportar fácilmente los inmaduros, que emergen posteriormente …

A New Conopid Fly From Florida And Georgia (Diptera: Conopidae), Sidney Camras

Insecta Mundi

A new species of Physoconops Szilady, P. (Pachyconops) weemsi, is described from Florida and Georgia. It is similar to two other species in the southeastern United States, P. floridanus Camras and P. brachyrhynchus Macquart, the main differential character being the shape of the female theca. The female thecae for all three are illustrated and a key to the three related Pachyconops species occurring in the southeastern United States is presented.

Bionomic Studies Of Papilio Demoleus Linnaeus, The Citrus Butterfly, (Lepidoptera: Papilionidae), From Lower Sindh, Pakistan, Arshad Munir, Nikhat Yasmin Siddiqui, Muhammad A. Rafi, Harry Pavulaan, David Wright

The Taxonomic Report of the International Lepidoptera Survey

Biological parameters of Papilio demoleus Linnaeus, the Citrus Butterfly, in Tando Muhammad Khan, lower Sindh, Pakistan are presented. This major agricultural pest was reared on Murraya koenigii (L.) Spreng. (Curry Leaf) and ten different varieties of Citrus sp. (Citrus) plants. The length of the adult mating period ranged 5 to 8 hours. Following mating, females laid 27.7 ± 3.3 eggs. Eggs hatched in 1.5 to 7 days. Mean durations of larval instars were 1.8 ± 0.1 (minimum) and 2.9 ± 0.1 (maximum) days respectively. Pupal duration was 5.5 to 20 days. Biotic factors including predators [praying mantis, ants, Common Garden …

Baseline Susceptibility Of Western Corn Rootworm (Coleoptera: Chrysomelidae) To Clothianidin, L.C. Magalhaes, B. W. French, Thomas E. Hunt, Blair D. Siegfried

Department of Entomology: Faculty Publications

Western corn rootworm, Diabrotica virgifera virgifera LeConte, neonate susceptibility to clothianidin, a contact and systemic neonicotinoid insecticide, was determined from both laboratory and field-collected populations. Neonates were exposed to filter paper treated with increasing clothianidin concentrations and mortality was evaluated after 24 h. Additionally, two populations were exposed to an artificial diet which was surface treated with clothianidin. Although larvae were five- to six-fold more sensitive to treated diet, results with treated filter paper were more reliable in terms of control mortality and required much less manipulation of rootworm larvae. Therefore, initial baseline comparisons were conducted using the filter paper …

Candidate Sex Pheromones Of The New World Screwworm Cochliomyia Hominivorax -- Summary & Abstract, David Carlson, Dennis Berkebile, Steven Skoda, S Russell Mihok

Department of Entomology: Faculty Publications

Females in established colonies of screwworm flies eventually lose the ability to make sex stimulant pheromone. This fact could result in the poor mating success observed during large sterile insect technique projects, such as the current Screwworm eradication program in Jamaica. Scientists at the Center for Medical, Agricultural and Veterinary Entomology in Gainesville, Florida were sought out by the International Atomic Energy Agency to test for and identify the sex pheromone in colonized Screwworm flies. Six chemical structures from previously published works were selected and all five new compounds were synthesized. Tests were conducted on colony screwworm flies from USDA, …

On New Characters Of The Eggs Of Embioptera With The Description Of A New Species Of Saussurembia (Anisembiidae), Janice Edgerly-Rooks, Claudia Szumik, Chanel Mccreedy

Biology

Nine egg characters for eleven species of Embioptera are described for the first time. Egg variability indicates its potential use in taxonomy. Here, we analyse the correlation of this variability with the ordinal classification. In addition, a new species of Saussurembia (Anisembiidae) from Trinidad is described, including classical traits in the systematics of Embioptera (adult male and female), as well as general features of the egg and maternal behaviour.
