(Lepidoptera: Gelechiidae) In North America, With Insights Into The Systematics Of Exoteleia Wallengren Using Characters Of The Adult, Immatures, Bionomics, And Dna Barcodes, David Adamski, Jean-Francois Landry, Steven C. Passoa, Robert Tracy
USDA Systematic Entomology Laboratory
Exoteleia dodecella (L.) (Lepidoptera: Gelechiidae), a native of Europe, was first documented from North America at several locations in eastern Canada. Additional records indicate this moth has now spread throughout New England and west to northern Pennsylvania, New York, and possibly into Michigan in the United States. A second introduction of E. dodecella has occurred near the Vancouver area of British Columbia in Canada. To help with the identification of E. dodecella, morphological, biological, and molecular evidence are presented. Key features of the adult, larval, and pupal morphology are compared to other species of Exoteleia and illustrated with line …

Host Recognition And Acceptance Behaviour In Cotesia Sesamiae And C. Flavipes (Hymenoptera: Braconidae), Parasitoids Of Gramineous Stemborers In Africa, Meshack Obonyo, Fritz Schulthess, Bruno Le Ru, Johnnie Van Den Berg, Paul André Calatayud
All Peer-Reviewed Publications
The host recognition and acceptance behaviour of two braconid larval parasitoids (Cotesia sesamiae and C. flavipes) were studied using natural stemborer hosts (i.e., the noctuid Busseola fusca for C. sesamiae, and the crambid Chilo partellus for C. flavipes) and a non-host (the pyralid Eldana saccharina). A single larva was introduced into an arena together with a female parasitoid and the behaviour of the wasp recorded until it either stung the larva or for a maximum of 5 min if it did not sting the larva. There was a clear hierarchy of behavioural steps, which was similar for both parasitoid species. …

University of Nebraska-Lincoln
Niche Specialization And Conservation Biology Of Cicindela Nevadica Lincolniana, Tierney R. Brosius
Department of Entomology: Dissertations, Theses, and Student Research
As with many organisms across the globe, Cicindela nevadica lincolniana is threatened with extinction. Understanding ecological factors that contribute to extinction vulnerability and what methods aid in the recovery of those species is essential in developing successful conservation programs. Here we examine behavioral mechanisms for niche partitioning along with improving techniques for captive rearing protocol and increasing public awareness about the conservation of this local insect. Ovipositional selectivity was examined for Cicindela nevadica lincolniana, Cicindela circumpicta, Cicindela togata, Cicindela punctulata, and Cicindela fulgida. Models reflect that these species of co-occurring tiger beetles select different ranges of salinity in which to …

Nestmate Recognition And The Role Of Cuticular Hydrocarbons In The African Termite Raiding Ant Pachycondyla Analis, Abdullahi A. Yusuf, Christian W.W. Pirk, Robin M. Crewe, Peter G.N. Njagi, Ian Gordon, Baldwyn Torto
All Peer-Reviewed Publications
Cuticular hydrocarbons (CHCs) are used for chemical communication among nestmates in many ant species, and they may play a role in the discrimination of nestmates and non-nestmates. Using the mandible opening response (MOR) bioassay, we tested the response of the African termite raiding ant, Pachycondyla analis, to CHC extracts of nestmates and non-nestmates. The ants were able to distinguish control chemical cues, from nestmate CHCs, and from non-nestmate CHCs, and, based on a CHC recognition threshold, aggression was demonstrated toward non-nestmates. Gas chromatography (GC) and GC-mass spectrometric analyses showed that CHC components of different ant colonies had chain lengths ranging …

Environmental Correlates Of Abundances Of Mosquito Species And Stages In Discarded Vehicle Tires, Donald A. Yee, Jamie M. Kneitel, Steven A. Juliano
Faculty Publications – Biological Sciences
Discarded vehicle tires are a common habitat for container mosquito larvae, although the environmental factors that may control their presence or abundance within a tire are largely unknown. We sample discarded vehicle tires in six sites located within four counties of central Illinois during the spring and summer of 2006 to determine associations between a suite of environmental factors and community composition of container mosquitoes. Our goal was to find patterns of association between environmental factors and abundances of early and late instars. We hypothesized that environmental factors correlated with early instars would be indicative of oviposition cues, whereas environmental …

We evaluated selected soybean, Glycine max (L.) Merr., genotypes during their reproductive stages for resistance to the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), under greenhouse conditions and documented the categories of aphid-resistant soybean. Two screening studies were performed to assess the level of resistance to the soybean aphid on six soybean genotypes during the reproductive stages of development. Significant differences in aphid damage ratings were detected among the soybean evaluated in the screening studies. Three genotypes (KS4202, K-1639-2, and K1621) were considered moderately resistant based on the assessed damage ratings. Two of these genotypes (K-1639-2 and KS4202), along with …

Biotic And Abiotic Influences On Within-Plant Distribution Of Soybean Aphid (Hemiptera: Aphididae: Aphis Glycines), Tierney R. Brosius, Leon G. Higley, Thomas E. Hunt
Department of Entomology: Faculty Publications
The within-plant distribution of soybean aphid, Aphis glycines Matsumura has been attributed to various causes, yet it is unclear which factor or combination of factors most influence aphid within-plant distribution. Understanding soybean aphid distribution within the soybean canopy is important both in developing sampling programs and in evaluating injury. Because natural enemies have the potential to alter aphid dispersion, we examined how within-plant distribution of soybean aphid was influenced by different natural enemies. Field cages of different mesh diameters were used to exclude different sizes of natural enemies from aphid infested plots. Plots were surveyed and both natural enemy density …

The Prospects For Sequencing The Western Corn Rootworm Genome, Nicholas Miller, S. Richards, T. W. Sappington
Department of Entomology: Faculty Publications
Historically, obtaining the complete sequence of eukaryotic genomes has been an expensive and complex task. For this reason, efforts to sequence insect genomes have largely been confined to model organisms, species that are important to human health and representative species from a few insect orders. This situation is set to change as a number of ‘next generation’ sequencing technologies are making largescale DNA sequencing both affordable and accessible. Sequencing the genome of the western corn rootworm, Diabrotica virgifera virgifera, is likely to become a realistic proposition within the next 2 years. In the meantime, there is an active community …

Department of Entomology: Faculty Publications
Melanoplus packardii Scudder was described in 1897. Three additional closely-related species were later described and their status as species has been questioned on numerous occasions. We examined morphology from specimens collected in Nebraska which fit descriptions of three of the four forms and specimens that appeared to be hybrids. We found distinct morphological characters suggesting species status for M. foedus and M. packardii, but not for M. foedus fluviatilis. Examination of aedeagi of these three forms suggests that M. foedus and M. packardii are each distinct, but that the aedeagi of M. f. fluviatilis and M. f. foedus cannot …

Varroa Mites And Honey Bee Health: Can Varroa Explain Part Of The Colony Losses?, Yves Le Conte, Marion D. Ellis, Wolfgang Ritter
Department of Entomology: Faculty Publications
Since 2006, disastrous colony losses have been reported in Europe and North America. The causes of the losses were not readily apparent and have been attributed to overwintering mortalities and to a new phenomenon called Colony Collapse Disorder. Most scientists agree that there is no single explanation for the extensive colony losses but that interactions between different stresses are involved. As the presence of Varroa in each colony places an important pressure on bee health, we here address the question of how Varroa contributes to the recent surge in honey bee colony losses.

Association Of Esterases In Resistance To Naled And Resmethrin In The Southern House Mosquito, Culex Quinquefasciatus, Jennifer R. Gordon
LSU Master's Theses
The vector-competency and its affinity for humans make C. quinquefasciatus an important target of mosquito abatement programs. Whenever such control programs are implemented, protocols to monitor frequencies and mechanisms of resistance to the insecticides used are necessary to optimize the efficacy of the management strategy and to slow development of resistance to the insecticides used. In the current study, susceptibilities to the two adulticides used by EBRMARC (naled and resmethrin) were monitored using field-collected mosquitoes and a topical and contact bioassay, respectively. My hypothesis was that esterase-mediated enhanced metabolism conferred resistance to both insecticides in populations of C. quinquefasciatus from …

Agronomy, Horticulture and Plant Science Faculty Publications
A potential pest of switchgrass, Panicum virgatum L., was first detected in South Dakota in 2004, where death of partially emerged leaves was noted in a small proportion of tillers. Similar “dead heart” symptoms were observed in switchgrass in Illinois during 2008 and adults of a stem-boring caterpillar were collected and identified as Blastobasis repartella (Dietz). In 2009, a survey of the central United States was used to estimate the distribution and abundance of this insect. In eight northern states, B. repartella was consistently found in both cultivated plots and natural stands of switchgrass. In four southern states, B. repartella …
