Rural Flies In The Urban Environment?, Gustave D. Thomas, Steven R. Skoda Feb 1993

Rural Flies In The Urban Environment?, Gustave D. Thomas, Steven R. Skoda

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Because metropolitan areas in the United States have been expanding at a dramatic rate, there has been direct competition between rural and urban interests for land. Also, market pressures often make it most profitable for meat producers to locate as close to urban centers as possible. A resultant growing interface between rural and urban centers, coupled with inadequate understanding of the people between the two centers, provides a potential for problems to develop. This book generally summarizes one area of contention - flies: few people tolerate flies in any setting anymore.

Nebraska Butterflies, Stephen M. Spomer Jan 1993

Nebraska Butterflies, Stephen M. Spomer

University of Nebraska State Museum: Staff and Affiliates, Publications

Nebraska is a crossroads of butterfly diversity. Many species reach their distributional limits in Nebraska. The 100th meridian, which runs through central Nebraska, appears to be a good distributional limit for many species. In short, eastern Nebraska contains butterflies similar or identical to those found in most of the eastern United States, central Nebraska has both eastern and western butterflies, and western Nebraska has a butterfly fauna more like the Rocky Mountains or Black Hills. Over 200 species of butterflies have been recorded in Nebraska, which is a higher number than most of our neighboring states. Some of our butterflies …

Comparative Toxicity Of Pyrethroid Insecticides To Terrestrial And Aquatic Insects, Blair Siegfried Jan 1993

Comparative Toxicity Of Pyrethroid Insecticides To Terrestrial And Aquatic Insects, Blair Siegfried

Department of Entomology: Faculty Publications

The acute toxicities of three pyrethroid insecticides (permethrin, cypermethrin, and bifenthrin) and one organophosphate insecticide (chlorpyrifos) were compared by topical application and static exposure to a variety of terrestrial and aquatic insects. Mayflies and damselflies were the most susceptible taxa tested by both exposure methods. The aquatic insects were generally more susceptible than the terrestrial insects when compared on a dose per body weight basis, although the differences were smaller than expected, given the extremely low concentrations that produce toxic effects by static exposure.


Activity And Electrophoretic Characterization Of Esterases In Insecticide-Resistant And Susceptible Strains Of German Cockroach (Dictyoptera: Blattellidae), Suresh K. Prabhakaran, Shripat T. Kamble Jan 1993

Activity And Electrophoretic Characterization Of Esterases In Insecticide-Resistant And Susceptible Strains Of German Cockroach (Dictyoptera: Blattellidae), Suresh K. Prabhakaran, Shripat T. Kamble

Department of Entomology: Faculty Publications

Strains of German cockroach, Blattella germanica (L.), were tested for resistance to three insecticides using the time-mortality response technique in comparison with known susceptible strains. Dursban-R and Macy strains indicated high levels of resistance to chlorpyrifos and moderate resistance to propoxur and cypermethrin. The hydrolytic activity of esterase enzymes was determined with a model substrate, p-nitrophenyl acetate. The specific activity of the enzymes increased with a corresponding increase in substrate concentration. Maximum activity was observed at 80 μM. The resistant strains had Significantly higher activity than the susceptible strains. The enzyme activity also increased with an increase in pH. …


Economic Injury Levels For Western Bean Cutworm, Loxagrotis Albicosta (Smith) (Lepidoptera: Noctuidae), Eggs And Larvae In Field Corn, Larry L. Appel, Robert J. Wright, John B. Campbell Jan 1993

Economic Injury Levels For Western Bean Cutworm, Loxagrotis Albicosta (Smith) (Lepidoptera: Noctuidae), Eggs And Larvae In Field Corn, Larry L. Appel, Robert J. Wright, John B. Campbell

Department of Entomology: Faculty Publications

Yield losses caused by different densities of western bean cutworm, [Loxagrotis albicosta (Smith)], egg masses and young larvae in field corn [Zea mays(L.), Pioneer 3475] were studied in replicated field cages in Perkins County, Nebraska, during 1989 and 1990. Treatments consisted of four egg masses per plant, one egg mass per plant, ten young larvae per plant, three young larvae per plant and an uninfested caged check. Infestations were timed to correspond with the natural occurrence of western bean cutworms each year. Larval density at dent stage and total grain yield were measured. Linear regression equations were …

Book Review: Aquatic Insect Ecology: 1. Biology And Habitat By J. V. Ward, Ross H. Arnett Jr. Sep 1992

Book Review: Aquatic Insect Ecology: 1. Biology And Habitat By J. V. Ward, Ross H. Arnett Jr.

Insecta Mundi

A comprehensive treatment of the ecology of aquatic insects in one place is needed for both students and researchers. Professor Ward is doing this in two volumes. The first volume covers the biology and habitats, as indicated in the subtitle, of the 13 insect orders that are either entirely aquatic at some stage, or those with some members aquatic at some stage. The second volume will be devoted entirely to the feeding ecology of these aquatic species.

Variation In The Terminalia Of Neohermes Concolor With A Key To Males Of Neohermes In Eastern North America (Megaloptera: Corydalidae: Chauliodinae), David E. Bowles, Michael A. Mathis Sep 1992

Variation In The Terminalia Of Neohermes Concolor With A Key To Males Of Neohermes In Eastern North America (Megaloptera: Corydalidae: Chauliodinae), David E. Bowles, Michael A. Mathis

Insecta Mundi

Males of Neohermes concolor (Davis) from the interior highlands of Arkansas, Oklahoma, and Missouri, and from Illinois, Indiana, and Kentucky exhibited considerable variation in male terminalia. Differences occurred in the size of the dorsal membrane of the ninth sternite and in the shape of the tenth tergite (anal plate) which varied from rounded to truncate-shaped. This observed variation does not appear to be geographically correlated. Females of N. concolor did not exhibit broad variation in terminalii. Little variation was observed among males of N. angusticollis (Hagen) and N. matheri Flint. The broad range of variation observed in the tenninalia of …

Rice Insects: The Role Of Host Plant Resistance In Integrated Management Systems, E. A. Heinrichs Sep 1992

Rice Insects: The Role Of Host Plant Resistance In Integrated Management Systems, E. A. Heinrichs

Department of Entomology: Faculty Publications

Insects are among the most important abiotic and biotic constraints to rice production. National rice research programs are in various stages in the development and implementation of integrated pest management (IPM) stratagies for rice insect control. Among the various control tactics, insect resistant cultivars are sought as the major tactic in rice IPM. Through the activities of interdisciplinary teams of scientists significant progress has been made in the development and release of insect resistant cultivars to farmers. Because of its compatibility with other control tactics insect resistance has proven to fit well into the IPM approach to rice insect control …
