Evidence Of The Establishment Of Cotesia Flavipes (Hymenoptera: Braconidae), A Parasitoid Of Cereal Stemborers, And Its Host Range Expansion In Ethiopia, E. Getu, W. A. Overholt, E. Kairu, C. O. Omwega

All Peer-Reviewed Publications

Three lepidopteran cereal stemborers, Chilo partellus (Swinhoe) (Crambidae), Busseola fusca Fuller, and Sesamia calamistis Hampson (Noctuidae) were collected from maize and sorghum in Ethiopia. The noctuid stemborers are indigenous to Africa while C. partellus is an introduced species from Asia. In 1999, the Asian stemborer parasitoid, Cotesia flavipes Cameron (Braconidae) was found to be widespread in Ethiopia, even though it had never been released in the country. In addition to attacking Chilo partellus, Cotesia flavipes was reared from B. fusca and S. calamistis. The origin of C. flavipes in Ethiopia may have been Somalia where it was released in 1997 …

Genetic Sexing Research On Screwworms, Steven Skoda, Dennis Berkebile, Margaret Allen

Department of Entomology: Faculty Publications

Few changes have been made to the basic concepts for using Mendelian, or `Classical', genetic techniques to develop genetic sexing strains of insects since they were first developed in the 1960's. They have been attempted for several species of insect pests with few successes. Scientists at the USDA-ARS Midwest Livestock Insects Research Unit have been developing techniques applicable to `Classical' genetic approaches and, recently, have begun exploring the applicability of transgenic techniques for developing genetic sexing strains of screwworms. Linkage analysis has shown that genes responsible for several mutant lines are not near each other. Cytogenetic techniques are being rejuvenated …

Fixation Of Type Locality For Lycaena Acmon Westwood And Characterization Of The Species And Its Distribution, Paul A. Opler

The Taxonomic Report of the International Lepidoptera Survey

Lycaena acmon Westwood, 1852 is based on a painting and plate legend in Westwood and Hewitson’s Genera of Diurnal Lepidoptera. The specimen illustrated was located in the British Museum Natural History and is the holotype by monotypy. The accompanying plate legend gives “California” as the type locality. Because the butterfly is a member of a complex of species, now considered in the genus Plebejus (Opler and Warren, 2003), that requires much systematic study, and some confusion exists on the identity of L. acmon, it is necessary to fix a more specific type locality, to characterize the species, …

Corrections To The Eretmocerus (Hymenoptera: Aphelinidae) Of Egypt And The Validation Of Two New Species, S. Abd-Rabou, G. A. Evans

Insecta Mundi

Abd-Rabou and Evans (2002) described Eretmocerus aegypticus Evans and Abd-Rabou and Eretmocerus parasiphonini Evans and Abd-Rabou. According to Article 16.4 of the International Code of Zoological Nomenclature (ICZN) (1999), for a name to be available, the author(s) of papers published after 1999, must accompany the description with a statement of intent as to where the primary type is deposited or to be deposited. Since the authors inadvertently did not state where the primary type for each species was to be deposited, the names of both of these species have been unavailable. To rectify this situation and comply with the requirements …

Synonymy Of Rhamphidera Skelley With Bancous Pic, Termitophilous Fungus Beetles (Coleoptera: Erotylidae), Paul E. Skelley, Miguel A. Alonso-Zarazaga

University of Nebraska State Museum: Entomology Papers

The genus Bancous Pic, originally described in the Heteromera (Rhysopaussidae) and later transferred to Cucujiformia (incertae sedis), was found to be congeneric with Rhamphidera Skelley (Erotylidae). Bancous is here placed in the family Erotylidae (Erotylinae, Tritomini) and Rhamphidera is moved into synonymy. This synonymy creates two new combinations: Bancous perplexus (Skelley) and Bancous eureka (Skelley). Bancous is redescribed and a lectotype is designated for Bancous irregularis Pic.

Effects Of Molasses Grass, Melinis Minutiflora Volatiles On The Foraging Behavior Of The Cereal Stemborer Parasitoid, Cotesia Sesamiae, Linnet S. Gohole, William A. Overholt, Zeyaur R. Khan, John A. Pickett, Louise E.M. Vet

All Peer-Reviewed Publications

Olfactory responses of the cereal stemborer parasitoid Cotesia sesamiae to volatiles emitted by gramineous host and nonhost plants of the stemborers were studied in a Y-tube olfactometer. The host plants were maize (Zea mays) and sorghum (Sorghum bicolor), while the nonhost plant was molasses grass (Melinis minutiflora). In single-choice tests, females of C. sesamiae chose volatiles from infested and uninfested host plants and molasses grass over volatiles from the control (soil). In dual-choice tests, the wasp preferred volatiles from infested host plants to those from uninfested host plants. There was no discrimination between molasses grass volatiles and those of uninfested …

Incomplete Sexual Isolation In Sympatry Between Subspecies Of The Butterfly Danaus Chrysippus (L.) And The Creation Of A Hybrid Zone, G. Lushai, D. A.S. Smith, I. J. Gordon, D. Goulson, J. A. Allen, N. Maclean

All Peer-Reviewed Publications

Subspecies chrysippus, dorippus and alcippus of the butterfly Danaus chrysippus differ at three biallelic colour gene loci. They have partially vicariant distributions, but their ranges overlap over a substantial part of central and East Africa, where hybridism is commonplace. We now report that the West African subspecies alcippus differs from other subspecies, not only in nuclear genotype but also in mitochondrial haplotype in both allopatry and sympatry. The maintenance of concordant nuclear and cytoplasmic genetic differences in sympatry, and in the face of hybridisation, is prima facie evidence for sexual isolation. Other evidence that suggests alcippus may be isolated from …

Enrichment Of A Single Clone From A High Diversity Library Of Phage-Displayed Antibodies By Panning With Anopheles Gambiae (Diptera: Culicidae) Midgut Homogenate, G. F. Killeen, B. D. Foy, R. H. Frohn, D. Impoinvil, A. Williams, J. C. Beier

All Peer-Reviewed Publications

A high diversity library of recombinant human antibodies was selected on complex antigen mixtures from midguts of female Anopheles gambiae Giles. The library of phage-displayed single chain variable region fragment constructs, derived from β-lymphocyte mRNA of naïve human donors, was repeatedly selected and reamplified on the insoluble fraction of midgut homogenates. Five rounds of panning yielded only one midgut-specific clone, which predominated the resulting antibody panel. In A. gambiae, the epitope was found throughout the tissues of females but was absent from the midgut of males. The cognate antigen proved to be detergent soluble but very sensitive to denaturation and …

Comparative Analysis Of Microsatellite Loci In Four Fruit Fly Species Of The Genus Ceratitis (Diptera: Tephritidae), F. N. Baliraine, M. Bonizzoni, E. O. Osir, S. A. Lux, F. J. Mulaa, L. Zheng, L. M. Gomulski, G. Gasperi, A. R. Malacrida

All Peer-Reviewed Publications

The possibility to cross-species amplify microsatellites in fruit flies of the genus Ceratitis was tested with the polymerase chain reaction (PCR) by analysing 23 Ceratitis capitata (Wiedemann) microsatellite markers on the genomic DNA of three other economically important, congeneric species: C. rosa (Karsch), C. fasciventris (Bezzi) and C. cosyra (Walker). Twenty-two primer pairs produced amplification products in at least one of the three species tested. The majority of the products were similar, if not identical in size to those expected in C. capitata. The structures of the repeat motifs and their flanking sequences were examined for a total of 79 …

Inheritance Of Methyl-Parathion Resistance In Nebraska Western Corn Rootworm Populations (Coleoptera: Chrysomelidae), Srivinas Parimi, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

Field populations of western corn rootworm, Diabrotica virgifera virgifera LeConte, were collected from three different sites (York Co., Phelps Co., and Saunders Co.) in Nebraska during 1996.Adult bioassays of these three populations were conducted with different concentrations of methyl-parathion and at a diagnostic concentration (1.0 μg/ml) to determine resistance levels among these populations. Self and reciprocal crosses were made between the two resistant and one susceptible laboratory-reared populations. Dose-responses and dominance ratios calculated for the four reciprocal crosses indicated that resistance was incompletely dominant in both strains, although in one of the strains there was an indication of sex linkage. …
