Natural History Of Belonuchus Nordmann Spp. And Allies (Coleoptera: Staphylinidae) In Heliconia L. (Zingiberales: Heliconiaceae) Flower Bracts, J. H. Frank, R. Barrera 2010 University of Florida

Natural History Of Belonuchus Nordmann Spp. And Allies (Coleoptera: Staphylinidae) In Heliconia L. (Zingiberales: Heliconiaceae) Flower Bracts, J. H. Frank, R. Barrera

Insecta Mundi

Adults, and in some species larvae, of several members of Belonuchus Nordmann (Coleoptera: Staphylinidae: Staphylininae) and a few related genera seem to be to various degrees consistently associated with flower bracts of the genus Heliconia (Zingiberales: Heliconiaceae). They are predators and eat various dipterous and lepidopterous larvae in that habitat. Adults of at least Belonuchus cephalotes (Sharp) and Odontolinus fasciatus Sharp are able to immerse completely in water to capture larvae and/or pupae of mosquitoes (Culicidae).

Adults and larvae of Belonuchus satyrus Erichson, and adults of B. cacao Blackwelder and B. rufipennis (F.) were found in water-filled flower bracts of …

Phma, A Ph-Sensitive Gfp Reporter For Cell Engulfment In Drosophila Embryos, Tissues And Cells, Elane Fishilevich, James A. J. Fitzpatrick, Jonathan S. Minden 2010 Carnegie Mellon University

Phma, A Ph-Sensitive Gfp Reporter For Cell Engulfment In Drosophila Embryos, Tissues And Cells, Elane Fishilevich, James A. J. Fitzpatrick, Jonathan S. Minden

Department of Entomology: Faculty Publications

Engulfment of apoptotic cells by phagocytosis ensures the removal of unwanted and defective cells. We developed a genetically encoded marker for cell engulfment, pHMA, which consists of the pH-sensitive derivative of GFP, pHluorin, fused to the actin-binding domain of Moesin. In healthy cells of Drosophila embryos and cultured cells, pHMA resides at the cell cortex. In dying cells, pHMA loses its cortical localization and reports a modest decrease in pH. In embryos, the dying cells lose their apical contacts, then move basally and are ultimately engulfed by neighboring cells or macrophages. The cell corpse material is strongly acidified soon after …


Sugar In Moderation: Sugar Diets Affect Short-Term Parasitoid Behaviour, Danielle Lightle, Mario Ambrosino, Jana C. Lee 2010 Oregon State University

Sugar In Moderation: Sugar Diets Affect Short-Term Parasitoid Behaviour, Danielle Lightle, Mario Ambrosino, Jana C. Lee

Entomology Papers from Other Sources

The biological control potential of parasitic wasps in the field is expected to increase with the provisioning of sugar sources, which increase longevity and replenish carbohydrate reserves. Apanteles aristoteliae is an important parasitoid of Argyrotaenia franciscana, the orange tortrix, an economic pest in fruit crops. In the present study, the effect of sugar diet on the physiological status of A. aristoteliae is investigated in the laboratory, as well as the effects of nutritional status on short-term olfactory orientation and parasitism behaviour, and the association between olfactory orientation and immediate parasitism activity. Levels of glycogen, fructose, total sugars, proportional weight …


Pollen Interception By Linyphiid Spiders In A Corn Agroecosystem: Implications For Dietary Diversification And Risk-Assessment, Julie A. Peterson, Susan Romero, James D. Harwood 2010 University of Nebraska-Lincoln

Pollen Interception By Linyphiid Spiders In A Corn Agroecosystem: Implications For Dietary Diversification And Risk-Assessment, Julie A. Peterson, Susan Romero, James D. Harwood

West Central Research and Extension Center, North Platte

Dietary diversification, including consumption of plant tissues such as pollen, can enhance the fecundity of generalist predators, resulting in improved control of pest prey. Supplemental pollen feeding has been observed in many natural enemies, including sheet-web spiders (Araneae: Linyphiidae), which represent a major component of food webs in agroecosystems. Their horizontal, ground-based webs have the potential to intercept pollen grains during anthesis of crop plants, providing the opportunity for consumption of pollen to occur. In laboratory feeding trials, Frontinella communis and Tennesseellum formicum (Araneae: Linyphiidae) readily fed on pollen grains dusted on their webs, with 82 and 92% of spiders …


Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman III, Rebecca F. Hazen 2010 Wright State University - Main Campus

Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman Iii, Rebecca F. Hazen

Biological Sciences Faculty Publications

Multitrophic interactions play key roles in the origin and maintenance of species diversity, and the study of these interactions has contributed to important theoretical advances in ecology and evolutionary biology. Nevertheless, most biodiversity inventories focus on static species lists, and prominent theories of diversity still ignore trophic interactions. The lack of a simple interaction metric that is analogous to species richness is one reason why diversity of interactions is not examined as a response or predictor variable in diversity studies. Using plant-herbivore-enemy trophic chains as an example, we develop a simple metric of diversity in which richness, diversity indices (e.g., …

Modeling Evolution Of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) To Transgenic Corn With Two Insecticidal Traits, David W. Onstad, Lance J. Meinke 2010 University of Illinois, Urbana

Modeling Evolution Of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae) To Transgenic Corn With Two Insecticidal Traits, David W. Onstad, Lance J. Meinke

Department of Entomology: Faculty Publications

Asimulation model of the population dynamics and genetics of western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), was created to evaluate the use of refuges in the management of resistance to transgenic insecticidal corn, Zea mays L., expressing one or two toxin traits. Hypothetical scenarios and a case study of a corn hybrid pyramided with existing toxins are simulated. In the hypothetical situations, results demonstrated that evolution is generally delayed by pyramids compared with deployment of a single-toxin corn hybrid. However, soil insecticide use in the refuge reduced this delay and quickened the evolution of resistance. Results were sensitive …

Degree-Day Requirements For Alfalfa Weevil (Coleoptera: Curculionidae) Development In Eastern Nebraska, A. R. Stilwell, Robert J. Wright, Thomas E. Hunt, Erin E. Blankenship

Department of Entomology: Faculty Publications

The alfalfa weevil, Hypera postica (Gyllenhal), is a serious, yet sporadic defoliator of alfalfa, Medicago sativa L., in Nebraska. A 2-yr study was conducted in 2005 and 2006 to test for variation in degree-day requirements by location in eastern Nebraska. Sampling took place along a latitudinal gradient in three regions of eastern Nebraska. Three fields were sampled in each region during the 2 yr of the study. Alfalfa weevil larval degree-day requirements were found to vary by latitude in eastern Nebraska. Alfalfa weevil larvae were discovered in southern regions after fewer developmental degree-days had accumulated than in fields in the …

(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. …


Niche Specialization And Conservation Biology Of Cicindela Nevadica Lincolniana, Tierney R. Brosius 2010 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 2010 International Centre of Insect Physiology and Ecology Nairobi

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 2010 University of Southern Mississippi

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 …
