Susceptibility Of House Fly (Diptera: Muscidae) Larvae To Entomopathogenic Nematodes (Rhabditida: Heterorhabditidae, Steinernematidae, David B. Taylor, Allen L. Szalanski, Byron J. Adams, Richard D. Peterson Ii

Department of Entomology: Faculty Publications

The potential for entomopathogenic nematodes to control flies in cattle feedlots was determined by screening 40 strains representing 8 species of Heterorhabditis Poinar and 5 species of Steinernema Travassos for virulence toward 3rd-instar house flies (maggots), Musca domestica L. None of the 22 strains of Heterorhabditis infecting maggots caused significant levels of mortality in a filter paper assay. Ten strains of Steinernema infected maggots, of which 7 strains--4 S. carpocapsa (Weiser), 2 S. feltiae (Filipjev), and 1 S. scapterisci (Nguyen & Smart) caused significant mortality. Ten Heterorhabditis strains and 10 Steinernema strains successllly reproduced for 22 generations in maggots. No …

Development Of Banded Sunflower Moth (Lepidoptera: Cochylidae) And Sunflower Moth (Lepidoptera: Pyralidae) On Three Diets, Jawahar L. Jyoti, Gary J. Brewer

Department of Entomology: Faculty Publications

A comparative study of the effects of sunflower moth diet, banded sunflower moth diet, and a modified sunflower moth diet was conducted on banded sunflower moth, Cochylis hospes Walsingham, and sunflower moth, Homoeosoma electellum (Hulst). Developmental times and survival to the pupal and adult stages were measured for each diet and pest species. Modified sunflower moth diet with incorporated sunflower leaf tissue gave faster developmental times and a higher percent pupation and adult eclosion for both sunflower moth species than either sunflower moth diet or banded sunflower moth diet. The modified sunflower moth diet that incorporates sunflower leaf tissue provides …

Arthropods On Pine Foliage In Urban Landscapes, Mary Ellen Dix, Frederick P. Baxendale

Department of Entomology: Faculty Publications

Urban landscapes are dense heterogenous matrices composed of turf broken up by tree patches or corridors (Forman and Godron, 1986, Landscape ecology. John Wiley, NY). Trees and their associated understory vegetation in the urban landscape provide food and protective habitat for many arthropods and their natural enemies and increase biological and spatial diversity (Andow, 1991, Annu. Rev. Entomol. 36:561-586). Pest management strategies that enhance the abundance of natural predator populations are alternatives to chemical pesticides. The goal of this research was to obtain essential baseline information on pine trees in turf landscapes by identifying common families or classes of arthropod …

Parasitoids Recovered From European Corn Borer, Ostrinia Nubilalis Hübner, (Lepidoptera: Pyralidae) Larvae In Nebraska, Thomas L. Clark, John E. Foster, John F. Witkowski, Blair D. Siegfried, Terence A. Spencer

Department of Entomology: Faculty Publications

Information about the current status of parasitoids attacking European com borer, Ostrinia nubilalis (Hübner). larvae is lacking in Nebraska. This study was conducted at multiple sites in 5 counties during 1995 and 1996 to determine the presence and prevalence of European com borer parasitoids in Eastern Nebraska. The braconid, Macrocentrus grandii Goidanich. was recovered from 8.9 and 10.2% of collected 5th instar European com borer larvae during 1995 and 1996, respectively. Recovery of this parasitoid had not been previously reported in Nebraska. Meanwhile. the ichneumonid, Eriborus terebrans (Gravenhorst), was recovered from 7.6 and 7.5% of collected larvae during the same …

Entomology In The Developing World, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

The global population continues to increase at an alarming rate, with 90% of the added population, or 85 million per year, occurring in the developing nations of the world. From 1950 to 1980, world food production doubled, with increases in the developing countries exceeding that of the developed countries. However, food production was not able to keep pace with the population in the developing world, where population increases were twice the rate of those in the developed world. Increases in per capita food production since the 1950s have been only one-third of the developed world because increased food production has …

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 …

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 …

Comments On A Review Of “Ants And Plants”, Pierre Jolivet

Insecta Mundi

The book, "Ants and Plants," so severely attacked in a review by Alan N. Andersen in 1996 (Australia Journal of Entomology, vol. 35, p. 200), was applauded, in it's French version, by another Australian, Prof. R. C. Buckley, in Science. The famous English ant specialist, Barry Bolton, also praised the book in his "Identification guide to the ant genera of the World" (1994). The text of both the French and English versions is the same, except the English version included many new hosts plants from Central America and Southeast Asia.
