Immunological Assessment Of An Insecticide Resistance-Associated Esterase In The Western Corn Rootworm, Xuguo Zhou, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

In previous investigations, we have determined that organophosphate resistance in the western corn rootworm, Diabrotica virgifera virgifera, is at least partially attributed to a group of non-specific carboxylesterases referred to as group II. Antiserum raised against a purified 66-kDa group II esterase is specific for the denatured enzyme. This antiserum reacts similarly with both beetle homogenates from resistant and susceptible populations, although there is much higher signal intensity in immunoblots of resistant relative to susceptible beetles. These results suggest that overproduction of group II esterases is the underlying basis of esterase-mediated resistance in D. v. virgifera by demonstrating that …

Stochastic Dietary Restriction Using A Markov-Chain Feeding Protocol Elicits Complex, Life History Response In Medflies, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Ying Zhang, Lawrence G. Harshman

Lawrence G. Harshman Publications

Lifespan in individually housed medflies (virgins of both sexes) and daily reproduction for females were studied following one of 12 dietary restriction (DR) treatments in which the availability of high-quality food (yeast–sugar mixture) for each fly was based on a Markov chain feeding scheme – a stochastic dietary regime which specifies that the future dietary state depends only on the present dietary state and not on the path by which the present state was achieved. The stochastic treatments consisted of a combination of one of four values of a ‘discovery’ parameter and one of three values of a ‘persistence’ parameter. …

Tritrophic Interaction Of Parasitoid Lysiphlebus Testaceipes (Hymenoptera: Aphidiidae), Greenbug, Schizaphis Graminum (Homoptera: Aphididae), And Greenbug-Resistant Sorghum Hybrids, Mahmut Dogramaci, Z. B. Mayo, Robert J. Wright, John C. Reese

Department of Entomology: Faculty Publications

Interactions of the parasitoid Lysiphlebus testaceipes (Cresson) and the greenbug, Schizaphis graminum (Rondani), on greenbug-resistant ‘Cargill 607E’ (antibiosis), ‘Cargill 797’ (primarily tolerance), and -susceptible ‘Golden Harvest 510B’ sorghum, Sorghum bicolor (L.) Moench, were tested using three levels of biotype I greenbug infestation. The parasitoid infestation rate was 0.5 female and 1.0 male L. testaceipes per plant. For all three greenbug infestation levels, the parasitoid brought the greenbug under control (i.e., prevented the greenbugs from killing the plants) on both resistant hybrids, but it did not prevent heavy leaf damage at the higher greenbug infestation rates. At the low greenbug infestation …

Bulletin of the University of Nebraska State Museum (1924–2023)

This represents the first monographic and phylogenetic treatment of the order Lecanicephalidea. The main objective was to treat the Lecanicephalidea at the generic level, while providing information on morphology, taxonomic history, phylogenetic relationships, geographic distribution, and host associations of the group. Following an introduction to the morphology of the Lecanicephalidea, the phylogenetic placement of the group is addressed. This is followed by a review of the taxonomic history of the group and relationships within, including summaries of 29 previously used classification schemes. Despite the generic focus of this study, the taxonomic status of 137 previously recognized lecanicephalidean species was evaluated, …

Adult Dispersal Of Ostrinia Nubilalis Hübner (Lepidoptera: Crambidae) And Its Implications For Resistance Management In Bt-Maize, J. A. Qureshi, L. L. Buschman, James E. Throne, S. B. Ramaswamy

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Dispersal of European corn borer, Ostrinia nubilalis Hubner was examined by release and recapture of the dye marked adults and by capture of the feral adults in and around the large 50 ha center pivot irrigated fields of Bacillus thuringiensis (Bt) maize. Pheromone and black light traps were used to catch the adults. In 1999, 15 094 marked males and 7993 marked females were released, and in 2001, 13 942 marked males and 9977 marked females were released. In 1999, maximum mean recapture beyond the release point was 1.95 and 1.67% for males and females, but in 2001, the recapture …

Sperm Stratification And Paternity Success In Red Flour Beetles, Sara M. Lewis, Annika Kobel, Tatyana Fedina, Richard W. Beeman

Entomology Papers from Other Sources

When females are inseminated by multiple males, male paternity success (sperm precedence) is determined by the underlying processes of sperm storage and sperm utilization. Although informative for many questions, two-male sperm competition experiments may offer limited insight into natural mating scenarios when females are likely to mate with several males. In this study, genetic markers in Tribolium castaneum are used to trace paternity for multiple sires, and to determine whether displacement of stored sperm that occurs after a third mating equally affects both previous mates, or if fertilizations are disproportionately lost by the female’s most recent mate. For 20 days …

Department of Entomology: Faculty Publications

Buffalograss [Buchloe dactyloides (Nutt.) Engelm.] has the potential for increased use as a turfgrass species due to its low maintenance and water conservation characteristics. This study was conducted to estimate diversity and relationships among naturally occurring buffalograss genotypes based on the nuclear genome, using sequence-related amplified polymorphism (SRAP) markers. The 56 genotypes studied represented five ploidy levels collected from diverse geographic locations in the North American Great Plains. In addition, blue grama [Bouteloua gracilis (H.B.K.) Lag. Ex Steud.] and perennial ryegrass (Lolium perenne L.) were included as outgroups. Twenty-five combinations of forward and reverse primers were used. …

Only Large Amounts Of Powdered Sugar Applied Directly To Brood Cells Harms Immature Honey Bees, Nicholas P. Aliano, Marion D. Ellis

Department of Entomology: Faculty Publications

We applied measured amounts of powdered sugar directly to honey bee brood combs containing eggs and larvae of known age groups. 24 h later, we compared powdered sugar-treated brood with similarly aged cohorts of immature bees that did not receive powdered sugar. Low and high doses of powdered sugar (0.3 and 0.6 g per 151.5 ± 1.0 cells, respectively) caused significant egg removal of 62.2 ± 5.1% and 86.1 ± 5.1%, respectively, when compared to eggs that received no powdered sugar (t = 16.91; df = 29; P = 0.0001). Powdered sugar had no effect on 5-day-old honey bee larvae …

Identification, Cloning And Expression Of A Cry1ab Cadherin Receptor From European Corn Borer, Ostrinia Nubilalis (Hübner) (Lepidoptera: Crambidae), Ronald D. Flannagan, Cao-Guo Yu, John P. Mathis, Terry E. Meyer, Xiaomei Shi, Herbert A. A. Siqueira, Blair D. Siegfried

Department of Entomology: Faculty Publications

Transgenic corn expressing the Cry1Ab toxin from Bacillus thuringiensis is highly toxic to European corn borer, Ostrinia nubilalis, larvae. A putative Cry1Ab receptor (OnBt-R1) molecule was cloned and sequenced from a cDNA library prepared from midgut tissue of O. nubilalis larvae. The 5.6 Kb gene is homologous with a number of cadherin genes identified as Cry1 binding proteins in other lepidopterans. Brush border membrane vesicles were prepared using dissected midguts from late instars. A 220-kDa protein was identified as a cadherin-like molecule, which bound to Cry1Ab toxin and cross-reacted with an anti-cadherin serum developed from recombinant expression of a …

Quality Of Transgenic Laboratory Strains Of Cochliomyia Hominivorax (Diptera: Calliphoridae), Margaret L. Allen, Philip J. Scholl

Department of Entomology: Faculty Publications

Genetically modified, mass reared insects present novel possibilities for the future of insect control. One concern about manipulation of insects is a possible loss of strain quality due to the introduction of a foreign gene of any sort into the insect genome. Eight transgenic strains of screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), were compared with the wild-type parental laboratory strain in laboratory culture. Measurements of average fertility, fecundity, larval productivity, and longevity were analyzed. Two transgenic strains had significantly lower larval productivity than controls, one of which was explained by a homozygous lethal insertion of the transgene. Another strain produced …

Review Of Integrated Pest Management In The Global Arena, By K. M. Maredia, D. Dakouo, And D. Mota-Sanchez, Gary J. Brewer

Department of Entomology: Faculty Publications

Integrated Pest Management in the Global Arena is a large book with 39 chapters and >500 pages of text. Despite the wide range of topics and numerous contributing authors, the book is consistently well written and worth reading in its entirety or by selectively choosing particular topics. The book should be a welcome reference for researchers and extension personnel across disciplines as well as for policy makers in government agencies and nongovernmental organizations working to promote integrated pest management (IPM) and sustainable agriculture. The reader can select any chapter and find a relevant discussion of IPM. As someone who teaches …

Multiple Transatlantic Introductions Of The Western Corn Rootworm, Nicholas Miller, Arnaud Estoup, Stefan Toepfer, Denis Bourguet, Laurent Lapchin, Sylvie Derridj, Kyung Seok Kim, Philippe Reynaud, Lorenzo Furlan, Thomas Guillemaud

Department of Entomology: Faculty Publications

Prevention of biological invasions, as opposed to remedial eradication of invasive species, represents the most cost-effective and perhaps only hope for stemming the current homogenization of the world's biota (1). Here we describe the introduction routes into Europe of the western corn rootworm (Diabrotica virgifera virgifera, WCR), the most destructive pest of corn in the United States. Armed with this knowledge, it will be possible to better gauge the prevention strategies that might be adopted

Department of Entomology: Faculty Publications

Introdução: Os ecossistemas que compreendem as áreas de arroz irrigado e seus arredores abrigam uma grande diversidade de insetos (Hook, 1994). Muitos possuem importância para o homem, dentre eles os insetos-praga, que podem causar grandes impactos e prejuízos em lavouras orizícolas devido aos seus hábitos alimentares e reprodutivos. Outros insetos fazem parte desses agroecossistemas, como os inimigos-naturais, que compreendem predadores e parasitóides, que auxiliam no controle de insetospraga, desempenhando um papel fundamental no Manejo Integrado de Pragas (Heinrichs e Barrion, 2004). Nesse contexto, esse estudo objetivou avaliar a biodiversidade abundância de insetos, e a seletividade de inseticidas nas áreas de …

Expressed Sequence Tags From Diabrotica Virgifera Virgifera Midgut Identify A Coleopteran Cadherin And A Diversity Of Cathepsins, Blair D. Siegfried, N. Waterfield, R. H. Ffrench-Constant

Department of Entomology: Faculty Publications

The Western corn rootworm is the major pest of corn in the USA and has recently become the target for insect-resistant transgenic crops. Transgenic crops have switched the focus for identifying insecticide targets from the insect nervous system to the midgut. Here we describe a collection of 691 sequences from the Western corn rootworm midgut, 27% of which predict proteins with no matches in current databases. Of the remaining sequences, most predict proteins with either catalytic (62%) or binding (19%) functions, as expected for proteins expressed in the insect midgut. The utility of this approach for the identification of targets …

The susceptibility of the egg, pupa, and adult of Haematobia irritans (L.) (Diptera: Muscidae) to isolates of the fungi Metarhizium anisopliae (Metsch.) Sor., Beauveria bassiana (Bals.) Vuill., and Paecilomyces fumosoroseus (Wize) Brown and Smith, was evaluated under laboratory conditions. Groups of 20 eggs than 4 h old, pupae less than 48h old and adults were sprayed with a conidial suspension of each isolate. Eggs, pupae and adults of horn fly were susceptible to these entomopathogenic fungi. For treated eggs, the isolates Ma3, Ma 15, Ma25, Pfr1, and Pfr8 reduced adult emergence to 3.8% to 6.3% in comparison with the control …

A Strategy For Using Powdered Sugar To Reduce Varroa Populations In Honey Bee Colonies, Nicholas P. Aliano, Marion D. Ellis

Department of Entomology: Faculty Publications

We developed a technique to remove varroa (Varroa destructor) from adult honey bees (Apis mellifera) using powdered sugar. Our technique requires isolating a colony’s adult bee population in a detachable box prior to powdered sugar application. We designed a detachable ‘bee box’ that connects to the colony’s entrance and is capable of holding the adult bee population. By applying a bee repellent, Bee Go®, to a colony, we forced adult bees into the bee box where they were subsequently dusted with 225 g of powdered sugar. Adult honey bee populations treated in this manner dropped 76.7 ± 3.6% (n = …
