Parturition Hormone In The Tsetse Glossina Morsitans: Activity In Reproductive Tissues From Other Species And Response Of Tsetse To Identified Neuropeptides And Other Neuroactive Compounds, Jan Žďárek, Ronald J. Nachman, David L. Denlinger

All Peer-Reviewed Publications

Parturition hormone (PH) activity is present not only in the uterus of the tsetse Glossina morsitans but also in the oviducts of Bombyx mori and Schistocerca gregaria, as well as the ejaculatory duct of S. gregaria males. Activity thus appears to be present in the reproductive ducts of diverse insect taxa. To determine whether any the common insect neuropeptides are capable of mimicking the effect of PH, 35 identified neuropeptides and analogs were evaluated for PH activity. Modest PH activity was observed for only high doses of proctolin and a pyrokinin analog, thus suggesting that PH is unlikely to be …

Cytochrome P450-Mediated N-Demethylation Activity And Induction In Insecticide-Resistant And Susceptible Western Corn Rootworm Populations (Coleoptera: Chrysomelidae), Michael E. Scharf, Blair Siegfried, Lance J. Meinke, Robert J. Wright, Laurence D. Chandler

Department of Entomology: Faculty Publications

Elevated cytochrome P450 monooxygenase-based metabolism is associated with carbaryl and methyl parathion resistance in western corn rootworm (Diabrotica virgifera virgifera LeConte) populations in the state of Nebraska. The objectives of this study were to identify potential differences in cytochrome P450 in resistant and susceptible rootworm populations using the model substrate 4-chloro-N-methyl aniline (4-CNMA) and heme staining of microsomal proteins separated by SDS–PAGE. Baseline N-demethylation activity corresponded well with resistance to the N-methyl-substituted insecticide carbaryl among study populations. N-demethylation of 4-CNMA is NADPH dependent and inhibited by the cytochrome P450 inhibitor piperonyl butoxide, which confirms that the reaction is catalyzed …

Wright, Michael E. Scharf, Lance J. Meinke, Xuguo Zhou, Blair D. Siegfried, Laurence D. Chandler

Department of Entomology: Faculty Publications

Soil insecticides were evaluated in laboratory and field studies against larvae of an insecticide resistant population (Phelps County, NE) of western corn rootworm, Diabrotica virgifera virgifera LeConte. Insecticide toxicity was evaluated by topical application of technical insecticides to 3rd instars from Saunders County, NE (susceptible) and Phelps County populations. Resistance ratios (LD₅₀ Phelps County/LD₅₀ Saunders County) for the insecticides methyl parathion, tefluthrin, carbofuran, terbufos, and chlorpyrifos were 28.0, 9.3, 8.7, 2.6 and 1.3, respectively. Biochemical investigation of suspected enzymatic resistance mechanisms in 3rd instars identified significant elevation of esterase activity (alpha and beta naphthyl acetate hydrolysis [3.8- and …

Arthropod Succession On Rat Carrion In West Virginia, Aimee M. Hildreth-Whitehair

Theses, Dissertations and Capstones

Carcasses represent a temporary and changing food source for a varied, yet distinct, community of organisms. Arthropods are the major component of this community and are the driving force for the early decomposition process. Although carrion remain for only a finite time, they represent an ecosystem which has a distinctive faunal succession usually initiated by calliphorid flies and variously followed by staphylinid, histerid, and dermestid beetles (Reed, 1958; Payne, 1965; Greenberg, 1991). The developmental rate of arthropods and their faunal progression is being increasingly used in determining time or site of human death. The most widely used application of arthropods …

Proximate Constraints On Intruder Detection In The Dragonfly Perithemis Tenera (Odonata: Libellulidae): Effects Of Angle Of Approach And Background, Paul Switzer, Perri Eason

Faculty Research & Creative Activity

The implications of insects’ vision for territorial defense have been relatively little studied in the field. In the dragonfly Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intruders were directly in front of them; they also detected more intruders in front of them than from other angles. Intruders viewed against distant vegetation were detected more readily than were intruders against near vegetation. Residents detected more intruders …

South-West Medlfy Study Highlights Improved Control Strategies, Sonya Broughton, Francis De Lima

Journal of the Department of Agriculture, Western Australia, Series 4

Mediterranean fruit fly has become an extremely important pest of commercial orchards in recent years, with there being numerous reports of control problems from fruit growing districts in the South-west of Western Australia. To assist in finding a solution to the problem of effective Medfly control, a study commenced in July 1995 to develop further understanding of Medfly ecology and to evaluate control strategies under varying climatic and management conditions in the South-west region. Sonya Broughton and Francis De Lima report on the outcomes of the three-year study.

Nf422 Sunflower Head Moth Management, Ronald C. Seymour, Gary L. Hein, Ray E. Weed

University of Nebraska-Lincoln Extension: Historical Materials

Sunflower head moth identification and biology, management, and chemical control. Sunflower head moth, Homoeosoma electellum (Hulst), can cause substantial economic loss to commercial sunflowers in Nebraska and the surrounding region. Populations of sunflower head moth vary tremendously from year to year. Consequently, pest monitoring is important each growing season to determine when moths first appear and the extent of the infestation. Field scouting in confection sunflower fields is critical because of their higher value and the importance of maintaining quality. Topics include sunflower head moth identification and biology, management, and chemical control.

Thermotolerance And Rapid Cold Hardening Ameliorate The Negative Effects Of Brief Exposures To High Or Low Temperatures On Fecundity In The Flesh Fly, Sarcophaga Crassipalpis, Joseph Rinehart, George Yocum, David Denlinger

Entomology Papers from Other Sources

Although the immediate effects of temperature stress are well documented, the longer-term effects of such stresses are more poorly known. In these experiments, we investigate the effects of suboptimal and supraoptimal temperatures during pharate adult development on fecundity in the flesh fly, Sarcophaga crassipalpis Macquart. A 1 h cold shock at -10°C during the red-eye pharate adult stage decreases the fecundity of both sexes. Induction of rapid cold hardening by pre-treatment at 0°C for 2 h partially prevents reproductive impairment. Heat shock of pharate adults for 1 h at 45°C also reduces fecundity in both sexes, but inducing thermotolerance by …
