Phylogenetic Analysis Of The Subtribe Rutelina And Revision Of The Rutela Generic Groups (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), Mary Liz Jameson

University of Nebraska State Museum: Entomology Papers

This work provides a comprehensive review of the phylogeny and classification of the subtribe Rutelina and a revision of the genus Rutela (Rutelina). Because of the lack of a thorough study of all taxa in the subtribe and because of differing philosophies regarding categorical levels, the classification of the subtribe is currently unstable. Phylogenetic analyses of 32 representative genera or subgenera in the tribe Rutelini were conducted as a means of: (1) resolving classification conflicts within the subtribe Rutelina, (2) identifying monophyletic groups within the subtribe, and (3) identifying monophyletic lineages within the tribe Rutelini. Analyses were conducted using 128 …

The L3 Neuron And An Associated Prothoracic Network Are Involved In Calling Song Recognition By Female Crickets, John Stout, Nathan Carlson, Hilary Bingol, James Ramseier, Michael Bronsert, Gordon Atkins

Faculty Publications

In young virgin Acheta domesticus females, the spiking response of the prothoracic L3 auditory interneuron discriminates between calling songs (CSs) with phonotactically attractive and unattractive syllable periods (SPs), which parallels phonotactic discrimination. Presentation of a CS with an originally attractive SP, but with the intensity modulated so as to minimize L3's selective response, results in a CS with little phonotactic attractiveness. Conversely, a CS with an originally unattractive SP becomes much more attractive when the CS is intensity modulated in ways that duplicate L3's selective response. L3's discriminatory response to CS SP deteriorates with age, in parallel with decreased phonotactic …

Insect Resistant Rice, Maize And Wheat Cultivars In Sustainable Agriculture, E. A. Heinrichs, J. E. Foster

Department of Entomology: Faculty Publications

The achievement of self sufficiency in food production is a major objective of governments throughout the world. Insects are one of the major constraints that limit the production of food crops. To mitigate losses due to insects. insect resistant cultivars are sought as a major tactic in the development of integrated pest management strategies. The integration of insect resistant cultivars with other pest management tactics contributes to crop pest management strategies that are environmentally and economically acceptable. Multiple pest resistant crop cultivars have high yield stability when grown in pest-infested environments. Significant progress on a global basis has been achieved …

Differential Toxicity Of Atrazine To Selected Freshwater Algae, J.-X. Tang, Kyle D. Hoagland, Blair D. Siegfried

Department of Entomology: Faculty Publications

The documented presence of atrazine in surface waters has prompted a large number of studies on its potential adverse effects on nontarget organisms such as freshwater algae, which are the most important primary producers in aquatic habitats and are potential indicators of water quality (Blaise 1993). Recently, a comprehensive database of the ecological effects of atrazine, including 85 freshwater organisms, was compiled (Solomon et al. 1996). Based on this compilation of acute ( ≤ 4 day) or chronic (> 9 day) toxicity values, algae are the most susceptible aquatic organisms to atrazine, although it is apparent that different species and …

Use Of Rubidium To Label Lysiphlebus Testaceipes (Hymenoptera: Braconidae), A Parasitoid Of Greenbugs (Homoptera: Aphididae), For Dispersal Studies, Odair A. Fernandes, Robert J. Wright, Karl H. Baumgarten, Z. B. Mayo

Department of Entomology: Faculty Publications

A reliable method of labeling is needed to study dispersal of the braconid parasitoid, Lysiphlebus testaceipes (Cresson), an important biological control of greenbugs, Schizaphis graminum (Rondani), on grain sorghum, Sorghum bicolor (L.) Moench. The feasibility of using aqueous solutions of rubidium chloride (RbCl) applied as a foliar spray or soil drench to label greenbugs and L. testaceipes developing within greenbugs was studied. Laboratory and field studies were conducted to identify the minimal concentration of RbCl to assure labeling of greenbugs and wasps, persistence of Rb throughout the wasp's life span, mobility of Rb to unsprayed sorghum leaves, and feasibility of …

Toxicity Of Seven Monoterpenoids To Tracheal Mites (Acari: Tarsonemidae) And Their Honey Bee (Hymenoptera: Apidae) Hosts When Applied As Fumigants, Marion D. Ellis, Frederick P. Baxendale

Department of Entomology: Faculty Publications

Laboratory bioassays were conducted to characterize the acute toxicity of 7 monoterpenoids to tracheal mites, Acarapis woodi (Rennie), and their honey bee, Apis mellifera L., hosts. Citral, thymol, carvacrol, α-terpineol, pulegone, d-limonene, and menthol were applied as fumigants to mite-infested honey bees. Thymol and menthol were the most toxic compounds to honey bees, and α-terpineol was the least toxic. Menthol, citral, thymol, and carvacrol were more toxic to tracheal mites than to honey bees. Pulegone, d-limonene, and α-terpineol were more toxic to honey bees than to tracheal mites. Menthol was 18.9 times more toxic to tracheal mites than to …

Riparian Refugia In Agroforestry Systems, Mary Ellen Dix, Erol Akkuzu, Ned B. Klopfenstein, Jianwei Zhang, Mee-Sook Kim, John E. Foster

Department of Entomology: Faculty Publications

In the last 200 years, cultivation, grazing, and other activities initiated by humans have destroyed more than 80 percent of the strips of vegetation along North American and European streams and other bodies of water (Decamps and Naiman 1989; Petts et al. 1989). This disappearance of the riparian zones is continuing with little concern for ecological consequences. At the same time, riparian buffer strips are being promoted as a preferred management practice in the United States, especially in the Great Plains, to protect water resources from soil and chemical pollution (Schoeneberger 1994; Schoeneberger et al. 1995; Schultz et al. 1995a; …

Insect Pests And Arthropod Predators Associated With Tree-Turf Landscapes, Mary Ellen Dix, Frederick P. Baxendale

Department of Entomology: Faculty Publications

Sweep-nets and pitfall traps were used to examine the distribution and dynamics of predominant predators and pests in turfgrass foliage in parks, golf courses and suburban/rural landscapes in 1991 and 1992. Araneae, Formicidae, and Coccinellidae were the most abundant predators in the sweeps, while Araneae, Formicidae, and) Carabidae were the most abundant predators in the pitfall traps. In both years, Araneae comprised over 60% of the total predators in the sweep samples. Formicidae (>70%) and Araneae (13-19%) were the most abundant arthropod predators in the pitfall samples. Cicadellidae, Chrysomelidae, and Orthoptera accounted for over 96% of the prey in …
