Familiarity With Breeding Habitat Improves Daily Survival In Colonial Cliff Swallows, Charles R. Brown, Mary Bomberger Brown, Kathleen R. Brazeal Oct 2008

Familiarity With Breeding Habitat Improves Daily Survival In Colonial Cliff Swallows, Charles R. Brown, Mary Bomberger Brown, Kathleen R. Brazeal

School of Natural Resources: Faculty Publications

One probable cost of dispersing to a new breeding habitat is unfamiliarity with local conditions such as the whereabouts of food or the habits of local predators, and consequently immigrants may have lower probabilities of survival than more experienced residents. Within a breeding season, estimated daily survival probabilities of cliff swallows, Petrochelidon pyrrhonota, at colonies in southwestern Nebraska, USA, were highest for birds that had always nested at the same site, followed by those for birds that had nested there in some (but not all) past years. Daily survival probabilities were lowest for birds that were naive immigrants to …


Vertical Distribution Of Spiders (Araneae) On A Tropical Island, Eric Brown Oct 2008

Vertical Distribution Of Spiders (Araneae) On A Tropical Island, Eric Brown

Independent Study Project (ISP) Collection

The distribution of spiders into vertical layers was studied on Misali Island. In particular, differences in diversity, species richness, abundance, and body length were analyzed. A variety of collection methods were used in order to capture as many different species as possible from three levels of forest: leaf litter, groundcover (up to 1m), and understory (up to 3m). After being sorted to the morphospecies level, the spiders were cataloged and several statistical tests were run. These tests show that spiders do show species-level stratification between different levels of forest. They also pointed towards a particularly firm dividing line between species …


Improving Beekeeping On Unguja Island, Larken Root Oct 2008

Improving Beekeeping On Unguja Island, Larken Root

Independent Study Project (ISP) Collection

The purpose of this study was to investigate the current practices and methods for improvement of beekeeping on Unguja Island in Zanzibar. Beekeeping has been occurring for many years in Unguja but has retained traditional techniques with little improvement. Improvement can occur in the form of introduction of modern equipment, formation of beekeeping organizations, advancing and diversifying products, and gaining governmental support. Beekeeping is worthy of expansion because of its potential to increase rural income in a sustainable way as well as support conservation of forest areas. The study found that there has so far been little improvement of income …

All Peer-Reviewed Publications

The reproductive compatibility between four different species/populations of the tephritid parasitoid Psyttalia (Walker) species from Kenya and individuals of the morphologically identical Psyttalia concolor (Szépligeti) (Hymenoptera: Braconidae) from a laboratory culture in Italy used in augmentative biological control of olive fly, Bactrocera oleae (Gmelin) (Diptera: Tephritidae) was assessed through cross mating tests using single-pair and group mating methods. Reciprocal crosses among the species resulted in the production of viable offsprings up to the second generation. In spite of the successful production of viable offspring in the laboratory, Psyttalia species are known to have specific host fruit and/or host fly preferences …

Co-Up-Regulation Of Three P450 Genes In Response To Permethrin Exposure In Permethrin Resistant House Flies, Musca Domestica, Fang Zhu, Ting Li, Lee Zhang, Nannan Liu Sep 2008

Co-Up-Regulation Of Three P450 Genes In Response To Permethrin Exposure In Permethrin Resistant House Flies, Musca Domestica, Fang Zhu, Ting Li, Lee Zhang, Nannan Liu

Entomology Faculty Publications

BACKGROUND: Insects may use various biochemical pathways to enable them to tolerate the lethal action of insecticides. For example, increased cytochrome P450 detoxification is known to play an important role in many insect species. Both constitutively increased expression (overexpression) and induction of P450s are thought to be responsible for increased levels of detoxification of insecticides. However, unlike constitutively overexpressed P450 genes, whose expression association with insecticide resistance has been extensively studied, the induction of P450s is less well characterized in insecticide resistance. The current study focuses on the characterization of individual P450 genes that are induced in response to permethrin …

Temperature Affects Microbial Decomposition Of Cadavers (Rattus Rattus) In Contrasting Soils, David O. Carter, David Yellowlees, Mark Tibbett Sep 2008

Temperature Affects Microbial Decomposition Of Cadavers (Rattus Rattus) In Contrasting Soils, David O. Carter, David Yellowlees, Mark Tibbett

Department of Entomology: Faculty Publications

The ecology of soils associated with dead mammals (i.e. cadavers) is poorly understood. Although temperature and soil type are well known to influence the decomposition of other organic resource patches, the effect of these variables on the degradation of cadavers in soil has received little experimental investigation. To address this, cadavers of juvenile rats (Rattus rattus) were buried in one of three contrasting soils (Sodosol, Rudosol, and Vertosol) from tropical savanna ecosystems in Queensland, Australia and incubated at 29 °C, 22 °C, or 15 °C in a laboratory setting. Cadavers and soils were destructively sampled at intervals of …


Crickets, Erin W. Hodgson, Jessie Trina Sep 2008

Crickets, Erin W. Hodgson, Jessie Trina

All Current Publications

Crickets are closely related to grasshoppers and katydids, all belonging in the order Orthoptera. The family of “true crickets” is called Gryllidae, which includes more than 900 different species worldwide. In Utah, we have several species of field crickets and snowy tree crickets located throughout the state. True crickets are often confused with grasshoppers and katydids because they have similar body shapes and large hind legs for jumping.

The bee fauna of the Greater Puerto Rico area was studied. A review of the previous relevant studies is presented. An annotated catalog and information about the origin and distributional patterns are also provided. Thirty-nine species of bees occur in Puerto Rico and adjacent islands. This fauna is composed of four elements: exclusive Puerto Rican endemics (26.5%); Antillean endemics occurring on multiple islands (76.5%); continental species that have also colonized the Antilles (23.5%); and species introduced through human activity (12.8%). The bee fauna was both low in its diversity and showed the highest level of disharmony in relation to other …


A New Species Of The Genus Aiolopus Fieber (Oedipodinae: Acrididae) From Libya, Mohammad Kamil Usmani Aug 2008

A New Species Of The Genus Aiolopus Fieber (Oedipodinae: Acrididae) From Libya, Mohammad Kamil Usmani

Insecta Mundi

The genus Aiolopus was proposed by Fieber (1853) with Gryllus thalassinus Fabricius (1781) as the type species. Later, two genera Epacromia Fischer and Aeoloptilus Bei-Bienko were synonymized with Aiolopus by Rehn (1902) and Hollis (1968) respectively. The genus was revised by Hollis (1968) who recognized seven species. Only three species have been described after Hollis (1968): A. markamensis Yin, 1984, A. nigritibis Zheng and Wei, 2000 and A. puissanti Defaut, 2005. At present thirteen species of Aiolopus are known worldwide according to Eades and Otte (2008). Previously, three species of Aiolopus have been reported from Libya. The genus is now …


Gene Expression And Phenotype Response Of Drosophila Melanogaster To Selection., Kenneth W. Mcdonald Aug 2008

Gene Expression And Phenotype Response Of Drosophila Melanogaster To Selection., Kenneth W. Mcdonald

Electronic Theses and Dissertations

The evolution of phenotypic plasticity is currently a topic of paramount interest in a diverse field of sub-disciplines. Salience is placed by all fields in describing the interaction of selection and phenotypic plasticity and the consequence of this interaction more broadly on evolution. Lacking in the discussion is substantial empirical description of genotype/phenotype interactions that by definition constitute the plastic response to novel and stressful environments. Here, I present empirical observations that bring the interaction of genotype and phenotype into focus. Drosophila melanogaster populations subjected to selection for tolerance to low food or high alcohol conditions each exhibited an enhancement …


Investigation Of Gene And Protein Expression Based On Honey Bee (Apis Mellifera) Aging, Flight Experience, And Behavior, Azucena A. Benito, G. E. Mancinelli, A. Ammons, Michelle M. Elekonich Aug 2008

Investigation Of Gene And Protein Expression Based On Honey Bee (Apis Mellifera) Aging, Flight Experience, And Behavior, Azucena A. Benito, G. E. Mancinelli, A. Ammons, Michelle M. Elekonich

Undergraduate Research Opportunities Program (UROP)

Honeybees undergo a process of adult behavioral development, spending their first 2-3 weeks working inside the constant environment of the hive. At about 3 weeks of age workers leave the hive as foragers who gather pollen and nectar. Previous research found that bees show an enormous decline in immunity as a result of their transition from regular hive jobs to more difficult foraging activities. Foragers can be forced to go back into hive-tasks, thus becoming “reverted nurses” which may also allow a reversal of immunosenescence. Understanding how this happens could prove to be useful because if there is flexibility in …

Outstanding In Their Field: The Phenotype Of The 21st Century Plant Breeder, P. Stephen Baenziger, Robert A. Graybosch, Ismail M. Dweikat, Stephen N. Wegulo, Gary L. Hein, Kent M. Eskridge

Department of Entomology: Faculty Publications

Plant breeding is a highly interdisciplinary science that requires the skills and teamwork of many scientists to be successful. In the 21st century, plant breeding will reap the benefits of the rapid advances in genomics research and understanding, as well as, advances in information and mechanical technology. The skill and success of plant breeders will be determined by their ability to use their resources efficiently, retaining those proven methodologies and augmenting them with novel approaches to meet their breeding objectives. Once the objective is determined, the plant breeder must: 1. identify and incorporate the needed genetic variability, 2. inbreed and …


Longevity-Fertility Trade-Offs In The Tephritid Fruit Fly, Anastrepha Ludens, Across Dietary-Restriction Gradients, James R. Carey, Lawrence G. Harshman, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Zhen Zhang Aug 2008

Longevity-Fertility Trade-Offs In The Tephritid Fruit Fly, Anastrepha Ludens, Across Dietary-Restriction Gradients, James R. Carey, Lawrence G. Harshman, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Zhen Zhang

Lawrence G. Harshman Publications

Although it is widely known that dietary restriction (DR) not only extends the longevity of a wide range of species but also reduces their reproductive output, the interrelationship of DR, longevity-extension and reproduction is not well understood in any organism. Here we address the question: “Under what nutritional conditions do the longevity-enhancing effects resulting from food restriction either counteract, complement or reinforce the mortality costs of reproduction? To answer this question we designed a fine-grained DR study involving 4,800 individuals of the tephritid fruit fly Anastrepha ludens in which we measured sex-specific survival and daily reproduction in females in each …

C. chilonis was originally collected in Japan while C. flavipes was imported into Kenya from Pakistan. The host species used was the noctuid Sesamia calamistis (Hampson), the most important noctuid maize pest in the region. All three Cotesia species attacked and successfully developed in 2nd to …


Role Of Native Bees And Natural Habitats In Eggplant (Solanum Melongena) Pollination In Kenya, Barbara Gemmill-Herren, Alfred O. Ochieng' Aug 2008

Role Of Native Bees And Natural Habitats In Eggplant (Solanum Melongena) Pollination In Kenya, Barbara Gemmill-Herren, Alfred O. Ochieng'

All Peer-Reviewed Publications

The pollination requirements of eggplant (Solanum melongena) were investigated. One variety of eggplant exhibited a significantly reduced seed set in absence of pollinators, and two varieties significantly increased seed numbers when pollen deposition was enhanced. Two solitary bee species, Xylocopa caffra and Macronomia rufipes, were identified as effective pollinators of the crop. The visitation rates of these pollinators to eggplant flowers declined significantly with distance from the wild habitat. The importance of wild plants as alternative forage source for pollinators was assessed by a survey of the flowering plants in different habitats surrounding eggplant fields. While ruderal farm weeds provide …
