Color Forms Of Monocesta Coryli (Say) In West Virginia (Coleoptera: Chrysomelidae), Shawn M. Clark

Insecta Mundi

Monocesta coryli (Say) is rather widespread in the eastern United States. In life, the beetles are usually bright yellow with the basal and apical thirds of the elytra metallic blue. In pinned specimens, the yellow areas fade to pale tan. A number of years ago (Clark, 1986), I reported on an unusual color form that occurs in southern Ohio, the dark elytral markings being either entirely absent or very poorly developed. More recently (Clark, 2000), I stated that both forms occur in West Virginia, but I gave very little information regarding the distribution of each.

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 …

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 …

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 …

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 …
