Taxonomy, Phylogeny, And Biogeography Of The Genus Asydates Casey (Insecta: Coleoptera: Melyridae), Jonathan R. Mawdsley

Insecta Mundi

The genus Asydates Casey (Coleoptera: Melyridae) is revised, containing three species from Arizona and California: A. explanatus Casey; A. inyoensis (Blaisdell), new combination; and A. rufiventris Casey. The monotypic genus Pseudasydates Blaisdell is placed in synonymy with Asydates Casey, syn. nov., and Asydates puncticeps Blaisdell is placed in synonymy with Asydates explanatus Casey, syn. nov. A key separating adults of Asydates species is provided, and the results of a computerized cladistic analysis of Asydates species are presented. GIs mapping of Asydates species distributions indicates that these species are nearly allopatric, with A. explanatus found in the lower Colorado River basin …

Oxidative Responses Of Resistant And Susceptible Cereal Leaves To Symptomatic And Nonsymptomatic Cereal Aphid (Hemiptera: Aphididae) Feeding, Xinzhi Ni, Sharron S. Quisenberry, Tiffany Heng-Moss, John P. Markwell, Gautam Sarath, Robert Klucas, Frederick P. Baxendale

Department of Entomology: Faculty Publications

The impact of the leaf-chlorosis-eliciting Russian wheat aphid, Diuraphis noxia (Mordvilko), and the nonchlorosis-eliciting bird cherry-oat aphid, Rhopalosiphum padi (L.), feeding on D. noxia-susceptible and -resistant cereals was examined during the period (i.e., 3, 6, and 9 d after aphid infestation) that leaf chlorosis developed. After aphid number, leaf rolling and chlorosis ratings, and fresh leaf weight were recorded on each sampling date, total protein content, peroxidase, catalase, and polyphenol oxidase activities of each plant sample were determined spectrophotometrically. Although R. padi and D. noxia feeding caused significant increase of total protein content in comparison with the control cereal …

Blend Effects In The Toxicity Of The Essential Oil Constituents Of Ocimum Kilimandscharicum And Ocimum Kenyense (Labiateae) On Two Post-Harvest Insect Pests, Jembere Bekele, Ahmed Hassanali

All Peer-Reviewed Publications

The lethal toxicity of major components of the essential oils of Ocimum kilimandscharicum and O. kenyense and of selected blends of these against Sitophilus zeamais and Rhyzopertha dominica were compared with those of the full blends of the essential oils. The compounds were assayed in amounts and proportions present in the minimum 100% lethal dose of the oils. Whereas a major component of O. kilimandscharicum was found to be largely responsible for the toxic action of its essential oil against R. dominica, the results with the other treatments indicated that the toxic action of the essential oils were due to …

The Wings Of Bombyx Mori Develop From Larval Discs Exhibiting An Early Differentiated State: A Preliminary Report, Madhuri Kango-Singh, Amit Singh, K. P. Gopinathan

Biology Faculty Publications

Lepidopteran insects present a complex organization of appendages which develop by various mechanisms. In the mulberry silkworm, Bombyx mori, a pair of meso- and meta-thoracic discs located on either side in the larvae gives rise to the corresponding fore- and hind-wings of the adult. These discs do not experience massive cell rearrangements during metamorphosis and display the adult wing vein pattern. We have analysed wing development in B. mori by two approaches, viz., expression of patterning genes in larval wing discs, and regulatory capacities of larval discs following explantation or perturbation. Expression of Nubbin is seen all over the presumptive …

Clarification Of And Comments On Northern Speyeria Hydaspe Subspecies (Lepidoptera: Nymphalidae), Norbert G. Kondla

The Taxonomic Report of the International Lepidoptera Survey

The geographic distribution and use of three northern Speyeria hydaspe subspecies names is reviewed. This is necessary due to literature errors about the type locality of subspecies rhodope (Edwards, 1874). The correct placement of the rhodope type locality renders the name S. hydaspe sakuntala (Skinner, 1911) of interior British Columbia as a junior synonym of S. hydaspe rhodope. The name S. hydaspe minor (McDunnough, 1927) is available for the coastal populations by those who recognize these as different from those of the interior.

Effects Of Stable Flies (Diptera: Muscidae) On Weight Gains Of Grazing Yearling Cattle, J.B. Campbell, S.R. Skoda, Dennis Berkebile, D. J. Boxler, G.D. Thomas, D. C. Adams, R. Davis

Department of Entomology: Faculty Publications

Differences in weight gains caused by stable flies, Stomoxys calcitrans (L.), on grazing yearling steer/calves averaged 0.2 kg per steer in a 3-yr study on canyon range pastures in West Central Nebraska. Stable fly numbers averaged 0.85 per front leg on treated calves and 3.64 per front leg on control calves. In 2 of the 3 yr after the grazing trials were completed, the calves were placed in a feedlot and fed a finishing ration. Compensatory gain did not occur in the feedlot after the stable fly stress was removed.

Detection Of The Phototoxic Dye Phloxine B In Anastrepha Ludens (Loew) (Diptera: Tephritidae), Apis Mellifera Linnaeus (Hymenoptera: Apidae) And Honey, Aleena M. Tarshis Moreno

Theses and Dissertations - UTB/UTPA

A spectrophotometric method for detection of phloxine B, a phototoxic dye proposed as a replacement for malathion bait sprays, in extracted tissues of Anastrepha ludens, Apis mellifera and in honey was developed. Dye detection was increased with a pH change from 6 to 13.7 in tissues or from 3.7 to 8 in honey with 2% sodium hydroxide. An LC 50 of 29.62 ppm phloxine B in 30% sucrose was obtained by feeding honey bees. A predictive model for dye in insect tissues and honey was developed and shown to be 89–92% effective. This study provides a forensic approach to determine …

Changes In Thermotolerance And Hsp70 Expression With Domestication In Drosophila Melanogaster, R. A. Krebs, S. (Stephen) P. Roberts, B. R. Bettencourt, M. E. Feder

Biological Sciences Faculty Research & Creative Works

To Examine How the Duration of Laboratory Domestication May Affect Drosophila Stocks Used in Studies of Thermotolerance, We Measured Expression of the Inducible Heat-Shock Protein Hsp70 and Survival after Heat Shock in D. Melanogaster Strains Recently Collected from Nature and Maintained in Laboratory Culture for Up to 50 or More Generations. after an Initial Increase in Both Hsp70 Expression and Thermotolerance Immediately after Transfer to Laboratory Medium, Both Traits Remained Fairly Constant over Time and Variation among Strains Persisted through Laboratory Domestication. Furthermore, Variation in Heat Tolerance and Hsp70 Expression Did Not Correlate with the Length of Time Populations Evolved …

Eremophygus Bicolor (Gutiérrez) (Coleoptera: Scarabaeidae: Rutelinae: Rutelini): A New Tribal And Generic Placement For The Bolivian Scarab Platycoelia Bicolor (Gutiérrez) (Anoplognathini), Andrew Smith, Mary Liz Jameson

University of Nebraska State Museum: Entomology Papers

Platycoelia bicolor (Gutiérrez) (Scarabaeidae: Rutelinae) is transferred from the tribe Anoplognathini, subtribe Platycoeliina, to the tribe Rutelini. Platycoelia bicolor is placed in the genus Eremophygus Ohaus and the taxonomic history of the species is discussed. The transfer creates a new combination, Eremophygus bicolor (Gutiérrez) and places the generic name Heterocallichloris Gutiérrez as a junior synonym of Eremophygus (new synonymy). Morphological characters that warrant the transfer are discussed.

Preliminary Checklist Of The Orthopteroid Insects (Blattodea, Mantodea, Phasmatodea,Orthoptera) Of Texas, John A. Stidham, Thomas A. Stidham

Insecta Mundi

Texas has one of the most diverse orthopteroid assemblages of any state in the United States, reflecting the varied habitats found in the state. Three hundred and eighty-nine species and 78 subspecies of orthopteroid insects (Blattodea, Mantodea, Phasmatodea, and Orthoptera) have published records for the state of Texas. This is the first such comprehensive checklist for Texas and should aid future work on these groups in this area.

Book Review: Fauna Iberica, Volume 14: Coleoptera, Scarabaeoidea I. (Martin-Piera, F. And J. I. Lopez-Colon), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

At over 500 pages, this is only the first volume of a probable three volume Spanish language treatment of the Scarabaeoidea of the Iberian peninsula. Volume one is a comprehensive and detailed piece of work in the grand tradition of faunas and floras. This first volume treats all of the "lower" scarabaeoids (Laparosticti) except for the Aphodiidae and Aegialiidae, which will appear in the next scarabaeoid volume. The third volume will treat the "higher" scarabs (Pleurosticti).

The book begins with a brief overview of the morphology and life cycle of scarabaeoids followed by a discussion on various relationship hypotheses of …
