First Record Of Acizzia Jamatonica (Hemiptera: Psyllidae) In North America: Friend Or Foe?, Michael D. Ulyshen, Douglass R. Miller Sep 2007

First Record Of Acizzia Jamatonica (Hemiptera: Psyllidae) In North America: Friend Or Foe?, Michael D. Ulyshen, Douglass R. Miller

USDA Systematic Entomology Laboratory

Acizzia jamatonica (Kuwayama) (Hemiptera: Sternorrhyncha: Psyllidae) is reported for the first time in North America. Because the species is thought to feed exclusively on Albizia, it may prove to be an effective biocontrol agent against the invasive Albizia julibrissin Durazzini in the southeastern United States. Because A. julibrissin is also an ornamental plant of some importance, the arrival of A. jamatonica may not be welcomed by many. This is the fourth invasive species of Acizzia to be found in the United States.

Inheritance Of 'Domestication' Traits In Bambara Groundnut (Vigna Subterranea (L.) Verdc.), Shravani Basu, Sean Mayes, Michael Davey, Jeremy A. Roberts, Sayed N. Azam-Ali, Richard Mithen, Remy S. Pasquet Sep 2007

Inheritance Of 'Domestication' Traits In Bambara Groundnut (Vigna Subterranea (L.) Verdc.), Shravani Basu, Sean Mayes, Michael Davey, Jeremy A. Roberts, Sayed N. Azam-Ali, Richard Mithen, Remy S. Pasquet

All Peer-Reviewed Publications

Controlled crosses in bambara groundnut were attempted between a range of thirty-six bambara groundnut landraces (thirty domesticated (V. subterranea var. subterranea) and six wild (V. subterranea var. spontanea)). Ten F1 seed were produced. Of these, eight germinated producing F2 populations. On seed set, four populations could be unambiguously confirmed as true crosses by F3 seed coat colour. A single F2 population, derived from a domesticated landrace from Botswana (DipC; female parent) crossed with a wild accession collected in Cameroon (VSSP11; male parent) was used to study a range of agronomic and domestication traits. These included; days to emergence, days to …

Etymology Of The Earwigfly, Merope Tuber Newman (Mecoptera: Meropeidae): Simply Dull Or Just Inscrutable?, Louis A. Somma, James C. Dunford Aug 2007

Etymology Of The Earwigfly, Merope Tuber Newman (Mecoptera: Meropeidae): Simply Dull Or Just Inscrutable?, Louis A. Somma, James C. Dunford

Insecta Mundi

The naturalist Edward Newman did not provide an etymology for the mecopteran Merope tuber when he described it in 1838. In 1872 Asa Fitch asserted that the genus was named after Merope one of the Pleiades sisters of Greek mythology; however, he provided no reason for his assumption. We researched several etymological alternatives. We concur with Fitch and conclude that Newman did indeed name the genus Merope after the dullest of the Pleiades sisters.

Generic Limits Of The Rhyparini With Respect To The Genus Termitodius Wasmann, 1894 (Coleoptera: Scarabaeidae: Aphodiinae), Paul E. Skelley Aug 2007

Generic Limits Of The Rhyparini With Respect To The Genus Termitodius Wasmann, 1894 (Coleoptera: Scarabaeidae: Aphodiinae), Paul E. Skelley

University of Nebraska State Museum: Entomology Papers

Three distinct tibial types are recognized within the Rhyparini (Scarabaeidae, Aphodiinae). Based on this, generic limits for the species of Termitodius Wasmann are reevaluated, with the Old World members being transferred to Termitodiellus Nakane. The resulting new combinations are: Termitodiellus besucheti (Paulian), Termitodiellus hammondi (Krikken and Huijbregts), Termitodiellus interruptus (Krikken and Huijbregts), Termitodiellus luzonensis (Howden), Termitodiellus monticola (Krikken and Huijbregts). New World members of Termitodius are split into two genera: Termitodius Wasmann and Aschnarhyparus Makhan. Aschnarhyparus soesilae Makhan is here relegated to a junior synonym of Termitodius peregrinus Hinton, new synonymy, with the resulting new combination being Aschnarhyparus peregrinus (Hinton). …

Gene Transcription During Exposure To, And Recovery From, Cold And Desiccation Stress In Drosophila Melanogaster, B. J. Sinclair, A. G. Gibbs, S. (Stephen) P. Roberts Aug 2007

Gene Transcription During Exposure To, And Recovery From, Cold And Desiccation Stress In Drosophila Melanogaster, B. J. Sinclair, A. G. Gibbs, S. (Stephen) P. Roberts

Biological Sciences Faculty Research & Creative Works

We Exposed Adult Male Drosophila Melanogaster to Cold, Desiccation or Starvation, and Examined Expression of Several Genes during Exposure and Recovery. Frost Was Expressed during Recovery from Cold and Was Up Regulated during Desiccation. Desiccation and Starvation (But Not Cold) Elicited Increased Expression of the Senescence-Related Gene Smp-30. Desat2 Decreased during Recovery from Desiccation, But Not in Response to Starvation or Cold. Hsp70 Expression Increased after 1 H of Recovery from Cold Exposure but Was Unchanged in Response to Desiccation or Starvation Stress, and Hsp23 Levels Did Not Respond to Any of the Stressors. We Conclude that D. Melanogaster's Responses …

All Peer-Reviewed Publications

Diadegma semiclausum (Hellén) (Hymenoptera: lchneumonidae), an exotic diamondback moth parasitoid, was released in two pilot areas (Werugha in Coast Region and Tharuni in Central Province) in Kenya. Fifteen month before release, observations on the diamondback moth, Plutella xylostella (Linnaeus), and local natural enemy population dynamics and pest damage were initiated in both areas and continued for three years after release. The P. xylostella population was bimodal with higher records during dry seasons. At Werugha, the peak population of P. xylostella was 16.8 per plant (October 2001); at Tharuni it was 12.8 (February 2002). Populations at Werugha declined from three months …

Evolution And Phylogeny Of The Scarab Subtribe Anisopliina (Coleoptera: Scarabaeidae: Rutelinae: Anomalini), Mary Liz Jameson, Estefania Mico, Eduardo Galante Jul 2007

Evolution And Phylogeny Of The Scarab Subtribe Anisopliina (Coleoptera: Scarabaeidae: Rutelinae: Anomalini), Mary Liz Jameson, Estefania Mico, Eduardo Galante

University of Nebraska State Museum: Entomology Papers

The subtribe Anisopliina (Scarabaeidae: Rutelinae: Anomalini) is associated with grasses, and its species are distributed in the Palaearctic, Oriental, Ethiopian, Nearctic and Neotropical biogeographical regions. Phylogenetic analysis of adult morphological characters was conducted to examine the monophyly and classification of the group, as well as to examine characters associated with grass pollinivory and graminivory. We review the biology, phylogeny and classification of the Anisopliina and provide an overview of each genus. The analysis of ninety-one morphological characters using parsimony does not support the monophyly of the subtribe Anisopliina. Instead, the results provide support for a group referred to here as …

Direct And Indirect Effects Of Animal Detritus On Growth, Survival, And Mass Of Invasive Container Mosquito Aedes Albopictus (Diptera : Culicidae, Donald A. Yee, Banugopan Kesavaraju, Steven A. Juliano Jul 2007

Direct And Indirect Effects Of Animal Detritus On Growth, Survival, And Mass Of Invasive Container Mosquito Aedes Albopictus (Diptera : Culicidae, Donald A. Yee, Banugopan Kesavaraju, Steven A. Juliano

Faculty Publications – Biological Sciences

Compared with plant detritus, animal detritus yields higher growth rates, survival, adult mass, and population growth of container-dwelling mosquitoes. It is unclear whether the benefit from animal detritus to larvae results from greater microorganism growth, direct ingestion of animal detritus by larvae, or some other mechanism. We tested alternative mechanisms by which animal detritus may benefit the invasive container-dwelling mosquito Aedes albopictus (Skuse) (Diptera: Culicidae). In the laboratory, larvae were reared under three conditions with access to 1) detritus, but where microorganisms in the water column were reduced through periodic flushing; 2) water column microorganisms, but larvae had no direct …

Differential Expression Of The Crv1 Haemocyte Inactivation-Associated Polydnavirus Gene In The African Maize Stem Borer Busseola Fusca (Fuller) Parasitized By Two Biotypes Of The Endoparasitoid Cotesia Sesamiae (Cameron), C. W. Gitau, D. Gundersen-Rindal, M. Pedroni, P. J. Mbugi, S. Dupas Jul 2007

Differential Expression Of The Crv1 Haemocyte Inactivation-Associated Polydnavirus Gene In The African Maize Stem Borer Busseola Fusca (Fuller) Parasitized By Two Biotypes Of The Endoparasitoid Cotesia Sesamiae (Cameron), C. W. Gitau, D. Gundersen-Rindal, M. Pedroni, P. J. Mbugi, S. Dupas

All Peer-Reviewed Publications

Polydnaviruses are rarely studied for their natural variation in immune suppressive abilities. The polydnavirus harboring braconid Cotesia sesamiae, a widespread endoparasitoid of Busseola fusca and Sesamia calamistis in sub-Saharan Africa exists as two biotypes. In Kenya, the western biotype completes development in B. fusca larvae. However, eggs of the coastal C. sesamiae are encapsulated in this host and ultimately, no parasitoids emerge from parasitized B. fusca larvae. Both biotypes develop successfully in S. calamistis larvae. Encapsulation activity by B. fusca larvae towards eggs of the avirulent C. sesamiae was detectable six hours post-parasitization. The differences in encapsulation of virulent and …

The response of the small hive beetle (SHB), Aethina tumida Murray, to volatiles from a pollen-based diet conditioned by the feeding of 100 adult virgin female or male SHBs (4-8 weeks old) for 1, 3, 7 or 14 days is described and compared to that of the same diet inoculated with the yeast Kodamaea ohmeri (NRRL Y-30722), isolated from the beetle. In a wind tunnel, volatiles from pollen dough conditioned by beetles of either sex for 3 or 7 days lured significantly more beetles into traps than volatiles from unconditioned dough. In contrast, trap captures with volatiles from dough conditioned …

Livestock Farmers' Perception And Epidemiology Of Bovine Trypanosomosis In Kwale District, Kenya, S. O. Ohaga, E. D. Kokwaro, I. O. Ndiege, A. Hassanali, R. K. Saini

All Peer-Reviewed Publications

We did cross-sectional surveys in Kwale District, Kenya to determine the epidemiology of bovine trypanosomosis and livestock owners' perceptions of the disease. The surveys involved relative importance of trypanosomosis, examination of the current disease constraints, current control practices and drug-use patterns. Informal meetings were held with farmers and cattle census undertaken. Tsetse-fly densities and trypanosomosis prevalences in cattle were determined. A total of 132 farmers were interviewed. Trypanosomosis, anaplasmosis, East Coast fever, foot-and-mouth diseases were reported to be the major constraints to livestock production. Trypanosomosis was the most important compared to other diseases. Chemotherapy was the most widely used method …

Stable Fly Population Dynamics In Eastern Nebraska In Relation To Climatic Variables, David Taylor, Dennis Berkebile, Philip Scholl Jun 2007

Stable Fly Population Dynamics In Eastern Nebraska In Relation To Climatic Variables, David Taylor, Dennis Berkebile, Philip Scholl

Department of Entomology: Faculty Publications

Stable flies are among the most important pests of cattle and other livestock in North America. Their biting and annoyance reduce weight gains in cattle costing producers more than $1 billion per year in production losses. The factors that control population levels of this fly are poorly understood. A better understanding of these factors would permit producers to make informed decisions on when and where to implement control procedures based upon predicted populations levels. In this study, we evaluated the relationships between stable fly population levels and climatic variables. Temperature was the most important variable for the rise and fall …

Evaluation Of Warm-Season Turfgrasses For Resistance To The Chinch Bug, Blissus Occiduus, Thomas E. Eickhoff, Tiffany Heng-Moss, Frederick P. Baxendale Jun 2007

Evaluation Of Warm-Season Turfgrasses For Resistance To The Chinch Bug, Blissus Occiduus, Thomas E. Eickhoff, Tiffany Heng-Moss, Frederick P. Baxendale

Department of Entomology: Faculty Publications

The chinch bug, Blissus occiduus Barber, has been documented as a serious pest of buffalograss, Buchloe dactyloides (Nutall) Engelmann, and zoysiagrass, Zoysia japonica Steudel, turf grown in the Midwest. In addition to these two warm-season turfgrasses, several other warm-season grasses, including bermudagrass, Cynodon dactylon (L.) Pers., may also be at risk of B. occiduus infestations. This research evaluated selected bermudagrass and zoysiagrass cultivars for resistance to B. occiduus. Eleven zoysiagrass and four bermudagrass cultivars were evaluated for resistance to B. occiduus using no-choice studies under greenhouse conditions. Based on turfgrass damage ratings, the zoysiagrasses ‘Diamond’, ‘Zoro’, and ‘Emerald’, and bermudagrass …
