New Record For Tesarius Rakovic In South America (Coleoptera: Scarabaeidae: Aphodiinae: Psammodiini), Paul E. Skelley

Insecta Mundi

The genus Tesarius Rakovic (1981) is an interesting group of wingless, nearly eyeless (yet probably functionally blind), sand dune-dwelling scarabs. There are presently 5 species in the genus, T. sulcipennis (Lea 1904) from Tasmania and 4 species in western North America. One of these native North American species, T. caelatus (LeConte 1857) has been found in Britain (Johnson 1975). The genus is reviewed by Rakovic (1981, 1984), who provides a key to species.

The Use Of Live-Bait Traps For The Study Of Sylvatic Rhodnius Populations (Hemiptera: Reduviidae) In Palm Trees, F. Abad-Franch, F. Noireau, A. Paucar C., H. M. Aguilar V., C. Carpio C., J. Racines V.

University of Nebraska State Museum: Entomology Papers

Chagas disease is a major public health challenge for most Latin American countries. An initiative for the coordinated control of Chagas disease transmission throughout the Andean countries was launched in 1997. Since the early 1990s, control measures based on elimination of domestic/peridomestic triatomine colonies and screening of donor blood by serological testing have resulted in a reduction in incidence of ~70% in the Southern Cone countries (WHO, 1991; Dias & Schofield, 1999; Moncayo, 1999; WHO/CTD, 2000).

Permeabilization Of Cochliomyia Hominivorax (Diptera: Calliphoridae) Embryos, Dennis Berkebile, Jan Chirico, Roger A. Leopold

Department of Entomology: Faculty Publications

Embryos of the primary screwworm, Cochliomyia hominivorax (Coquerel), were successfully permeabilized for use in subsequent cryopreservation studies. Mortality was greater for eggs incubated for<5 h before treatment. The mean survival of embryos to first instars was 55.7, 61.1, and 62.6% when the embryos were incubated for 5, 5.5, and 6 h before treatment, respectively. The survival to the pupal and adult stages was low. An improved media for culturing the embryos during and immediately after treatment needs to be devised and the procedure for rearing the larval stages also needs to be altered to improve survival for emerging adults.

Atrazine Induction Of Cytochrome P450 In Chironomus Tentans Larvae, Francisca Miota, Blair Siegfried, Michael E. Scharf, Michael J. Lydy

Department of Entomology: Faculty Publications

Cytochrome P450-dependent aldrin epoxidation was characterized in third instar larvae of the aquatic midge, Chironomus tentans. Optimal in vitro assay conditions for the epoxidase were pH 7.6 and 31°C. Activity was linear up to 40 min of incubation time and 0.5 mg microsomal protein per incubation. The activity was concentrated in the mic rosomal fraction of whole body homogenates and was NADPH-dependent. The effect of atrazine exposure on aldrin epoxidase was measured to determine if this herbicide induces cytochrome P450-dependent activity. Comparisons of control and atrazine-exposed midges indicated increased epoxidase activity as a result of atrazine exposure, and a …

Fipronil Metabolism, Oxidative Sulfone Formation And Toxicity Among Organophosphate- And Carbamate-Resistant And Susceptible Western Corn Rootworm Populations , Michael E. Scharf, Blair D. Siegfried, Lance J. Meinke, Laurence D. Chandler

Department of Entomology: Faculty Publications

Fipronil toxicity and metabolism were studied in two insecticide-resistant, and one susceptible western corn rootworm (Diabrotica virgifera virgifera, LeConte) populations. Toxicity was evaluated by exposure to surface residues and by topical application. Surface residue bioassays indicated no differences in fipronil susceptibility among the three populations. Topical bioassays were used to study the relative toxicity of fipronil, fipronil. the mono-oxygenase inhibitor piperonyl butoxide, and fipronil's oxidative sulfone metabolite in two populations (one resistant with elevated mono-oxygenase activity). Fipronil and fipronil-sulfone exhibited similar toxicity and application of piperonyl butoxide prior to fipronil resulted in marginal effects on toxicity. Metabolism of …

Baseline Susceptibility Of The Corn Earworm (Lepidoptera: Noctuidae) To The Cry1ab Toxin From Bacillus Thuringiensis, Blair D. Siegfried, Terrence A. Spencer, Jessica Nearman

Department of Entomology: Faculty Publications

Susceptibility to Cry1Ab toxin from Bacillus thuringiensis (Bt) was determined for 12 field populations of neonate corn earworm, Helicoverpa zea (Boddie), from the United States. Earworm larvae were exposed to artificial diet treated with increasing Bt concentrations, and mortality and growth inhibition were evaluated after 7 d. The range of variation in Bt susceptibility indicated by growth inhibition was very similar to that indicated by mortality. Although interpopulation variation in susceptibility to both proteins was observed, the magnitude of the differences was small (less than or equal to fivefold). These results suggest that the observed susceptibility differences reflect natural variation …

Development Of Diagnostic Concentrations For Monitoring Bacillus Thuringiensis Resistance In European Corn Borer (Lepidoptera: Crambidae), Paula C.R.G. Marcon, Blair D. Siegfried, Terrence A. Spencer, W. D. Hutchinson

Department of Entomology: Faculty Publications

Two candidate diagnostic concentrations of the Cry1Ab and Cry1Ac toxins from Bacillus thuringiensis corresponding to the LC₉₉ and EC₉₉ (effective concentration that causes 99% growth inhibition) for European corn borer, Ostrinia nubilalis (Hubner), were determined based on previously obtained baseline data. Validation experiments using field-collected European corn borer populations from across North America showed that for Cry1Ab, a concentration corresponding to the upper limit of the 95% confidence interval of the LC₉₉, produced mortality .99% for all populations tested. However, for Cry1Ac, adjustments and further validation are probably necessary. Development of B. thuringiensis resistance monitoring programs …
