Assessing Needs For Computer Pest Management Software In Nebraska Agriculture, Robert J. Wright Aug 1992

Assessing Needs For Computer Pest Management Software In Nebraska Agriculture, Robert J. Wright

Department of Entomology: Faculty Publications

A mail survey was conducted to assess current computer hardware use and perceived needs of potential users for software related to crop pest management in Nebraska. Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no differences between the groups in several aspects of computer hardware use (percentage computer use, percentage IBM-compatible computer, amount of RAM memory, percentage with hard drive, hard drive size, or monitor graphics capability). Responses were similar among the three groups in several areas that are important …


Biochemical Characterization Of Hydrolytic And Oxidative Enzymes In Insecticide Resistant And Susceptible Strains Of The German Cockroach (Dictyoptera: Blattellidae), Blair Siegfried, Jeffrey G. Scott Aug 1992

Biochemical Characterization Of Hydrolytic And Oxidative Enzymes In Insecticide Resistant And Susceptible Strains Of The German Cockroach (Dictyoptera: Blattellidae), Blair Siegfried, Jeffrey G. Scott

Department of Entomology: Faculty Publications

We have identified resistance mechanisms in the German cockroach, Blattella gemanica (L.), for propoxur and chlorpyrifos in strains of cockroaches that display multiresistance to several organophosphate and carbamate insecticides. The resistance mechanisms involve the combined effects of increased oxidative and hydrolytic metabolism and both strains are resistant to chlorpyrifos and propoxur. Experiments designed to test for similarity in metabolic enzymes suggest that, although the mechanisms involve similar processes, the enzymes responsible for insecticide detoxification are different in the two strains. Both resistant strains exhibited enhanced activity toward a-naphtholic esters relative to a standard susceptible strain; however, analysis of the progeny …

Occurrence Of The Milliped, Stenodesmus Tuobitus (Chamberlin), West Of The Rio Grande (Polydesmida: Xystodesmidae), Rowland M. Shelley Mar 1992

Occurrence Of The Milliped, Stenodesmus Tuobitus (Chamberlin), West Of The Rio Grande (Polydesmida: Xystodesmidae), Rowland M. Shelley

Insecta Mundi

New records of the xystodesmid diplopod Stenodesmus tuobitus (Chamberlin) extend its range and those of the family and suborder Chelodesmidea into southwestern New Mexico, west of the Rio Grande. They confirm that it inhabits arid juniper environments at relatively low elevations as well as moist deciduous fir forests at high elevations, thereby lending credence to past records from the former habitat in Lincoln County. Discovery of the milliped in neighboring mountain ranges to the north and west is now likely, with the distant possibility that it may occur in eastern Arizona.


A New Genus And Species Of Flightless Longhorned Beetle From Central America (Coleoptera: Cerambycidae), Frank T. Hovore Mar 1992

A New Genus And Species Of Flightless Longhorned Beetle From Central America (Coleoptera: Cerambycidae), Frank T. Hovore

Insecta Mundi

An undescribed genus and species of flightless longhorned beetle, Apteralcidion lupierrei new genus, new species, in the subfamily Lamiinae, has been collected from giant thistle, Cirsium subcoriaccum, at high elevations in Costa Rica and Panama. This new taxon appears most-closely related to genera in the tribe Acanthocini.


Révision Du Genre Carolinaia Et Description De Nouveaux Taxa (Homoptera, Aphididae), Georges Remaudiere, Ana Lilla Munoz Viveros Mar 1992

Révision Du Genre Carolinaia Et Description De Nouveaux Taxa (Homoptera, Aphididae), Georges Remaudiere, Ana Lilla Munoz Viveros

Insecta Mundi

A new status is proposed for the genera Glabromyzus Richards, 1960 and Juncomyzus Hille Ris Lambers, 1965, which are now treated as subgenera of Carolinaia Wilson, 1911. The relationship between Carolinaia and Utamphorophoro Knowlton, 1947 is discussed. The new name C. (C.) tissoti is given for Carolinaia rhois Tissot, 1928 nec rhois Monell, 1879. The species known as Juncomyzus rhois (Takahashi, 1924) becomes C. (J.) japonica (Takahashi, 1961). The oviparous female of C. (G.) schlingeri, C. (J.) japonica, and C. (J.) nigra are described as well as the alate viviparous female and the male of the last species. …


Distribution Of The Centipede Scolopocryptops Sexspinosus (Say) In Alaska And Canada (Scolopendromorpha: Cryptopidae), Rowland M. Shelley Mar 1992

Distribution Of The Centipede Scolopocryptops Sexspinosus (Say) In Alaska And Canada (Scolopendromorpha: Cryptopidae), Rowland M. Shelley

Insecta Mundi

Specific Alaskan and Canadian localities are recorded for the chilopod Scolopocryptops sexspinosus (Say) (Cryptopidae), the only indigenous Nearctic scolopendromorph species occurring north of the lower 48 states. It occurs west of the crest of the Coast Range in British Columbia, extending northward to the southernmost islands of Alaska, and is recorded for the first time from eastern Canada, from Niagara Gorge, Ontario. Reports of S. rubiginosus Koch from southern Alaska are based on a misidentification of S. sexspinosus, and records from the north-central United States are too distant from the international border for it to be plausible for Manitoba …

Upper Eocene Robber Flies Of The Genus Ommatius (Diptera: Asilidae) In Dominican Amber, A. G. Scarbrough, George O. Poinar Jr. Mar 1992

Upper Eocene Robber Flies Of The Genus Ommatius (Diptera: Asilidae) In Dominican Amber, A. G. Scarbrough, George O. Poinar Jr.

Insecta Mundi

Ommatius fimbriatus and O. subtus are based upon four specimens embedded in Dominican amber from the El Mamey Formation in the Dominican Republic.
