Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

A rare species of nonbiting aquatic midge, Parochlus kiefferi (Garrett, 1925), was discovered in Squaw Creek in the Pine Ridge of northwest Nebraska. Parochlus is a genus of midge found throughout the Southern Hemisphere and is only represented by this one species in the Northern Hemisphere. The typical North American species distribution of P. kiefferi includes high alpine and northern latitude streams, so the collection of P. kiefferi from a low elevation and low-latitude stream in Nebraska represents a range extension for the species. A survey for P. kiefferi from 83 samples from 53 stream sites in northern Nebraska yielded …

Sensory Morphology And Chemical Ecology Of The Stable Fly, Stomoxys Calcitrans: Host-Seeking And Ovipositional Selection, Khanobporn Tangtrakulwanich

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies cause stress and discomfort to cattle, and other mammals, including humans and pets. Economic losses from stable flies to the U.S. cattle industry from loss of milk production and cattle weight gain exceed $2 billion annually.

Traditional stable fly management employing sanitation and insecticides is costly and often fails to provide acceptable levels of control. A novel method for managing stable flies involves the use of attractants and repellents. This approach could be used to enhance the current level of stable fly control and ultimately be incorporated into a sustainable stable fly management program.

Gravid females’ stable flies …

A Preliminary Report On The World Species Of Bemisia Quaintance And Baker And Its Congeners (Hemiptera: Aleyrodidae) With A Comparative Analysis Of Morphological Variation And Its Role In The Recognition Of Species, Raymond Gill

Analysis of molecular variance showed significant genetic variation in fall armyworm among all (28%) sample locations and individuals within (71%) sample locations; genetic variation of fall armyworm was minimal between sample locations grouped into regions. The pairwise fixation index (F_ST) comparisons showed significant genetic differentiation (0.288) among the 31 locations. However, dendrograms of results from cluster …

Genetic Differentiation Of Western Corn Rootworm Populations (Coleoptera: Chrysomelidae) Relative To Insecticide Resistance, Hong Chen, Haichuan Wang, Blair D. Siegfried

Department of Entomology: Faculty Publications

Abstract

As the single most important pest of field corn, Zea mays L., throughout most of the Corn Belt, the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), has undergone repeated selection for resistance to a variety of insecticides that persist widely among Nebraska populations. In this study, we used 11 microsatellite markers to genotype two populations with high levels of resistance to methyl-parathion and aldrin (Polk and Stromsburg), two populations with low and intermediate levels of resistance (Mead and Clay Center) from Nebraska, and one population from outside the Corn Belt (Safford, Arizona). The genetic diversity measured by …

Bean Leaf Beetle (Coleoptera: Chrysomelidae) And Bean Pod Mottle Virus In Soybean: Biology, Ecology, And Management, Buyung A. R. Hadi, Jeffrey D. Bradshaw, Marlin E. Rice, John J. Hill
