Description Of Khamul, Gen. N. (Hymenoptera: Chalcidoidea: Eurytomidae), With A Hypothesis Of Its Phylogenetic Placement, Michael W. Gates Jan 2008

Description Of Khamul, Gen. N. (Hymenoptera: Chalcidoidea: Eurytomidae), With A Hypothesis Of Its Phylogenetic Placement, Michael W. Gates

USDA Systematic Entomology Laboratory

Khamul n. gen., a distinctive eurytomid in the subfamily Eurytominae is described from the Neotropics based upon the type species, K. erwini, n. sp. A hypothesis of its phylogenetic placement within Eurytominae is presented, and four new species are described: K. erwini, K. gothmogi, K. lanceolatus, and K. tolkeini. Diagnostic features are included to distincguish this taxon from other eurytomines and a key to species presented. Its biology is unknown, but label data indicate walking stick eggs ( sp.; Phasmatodea: Prisopodidae) as a possible host.

Review Of What Wasp Is That?, Matthew L. Buffington Jan 2008

Review Of What Wasp Is That?, Matthew L. Buffington

USDA Systematic Entomology Laboratory

The digital revolution is in the midst of changing the very nature of systematic entomology. The discipline has been wrenched from the confines of traditional paper outlets for the dissemination of data through the brave new world of the internet, on-line journals and email attachments. At the root of this renaissance, however, there exists a need for the expertise, experience and basic courage of high-quality researchers to continue probing the Earth for the unusual, the spectacular, and the unbelievable.

Seed Predators Of Canada Milk-Vetch And Their Parasitoids, Arvid Boe, Paul J. Johnson Jan 2008

Seed Predators Of Canada Milk-Vetch And Their Parasitoids, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

Canada milk-vetch (Astragalus canadensis L.), North America’s most widespread species of Astragalus, is important for herbivores and granivores in natural ecosystems but suffers heavy seed losses to bruchids and curculionids. Our objectives were: (1) compile a species inventory and describe life histories of insects associated with seed production in Canada milk-vetch, and (2) determine frequencies of pod predation and primary parasitism in Canada milk-vetch. The seed predators were Acanthoscelides perforatus (Horn) and Tychius liljebladi Blatchley. Frequency of pod predation varied between two plant populations (46 and 70%) and between A. perforatus (37 %) and T. liljebladi (21 %). The primary …

Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom Jan 2008

Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom

Faculty Research & Creative Activity

Males of many species guard their mates to prevent rivals from usurping paternity of the potential offspring. Environmental conditions, such as temperature, may affect a male’s ability to guard a female effectively and consequently the amount of sperm competition that occurs. We tested whether temperature and light affected mating behavior in laboratory experiments on the Japanese beetle, Popillia japonica Newman, a species in which males guard females for minutes to many hours after mating. When tested in groups, under conditions of high temperature and high light, males guarded females for shorter periods of time and males and females both mated …

Biology Of Dendroctonus Murrayanae (Coleoptera: Curculionidae: Scolytinae) In Idaho And Montana And Comparative Taxonomic Notes, Malcolm M. Furniss, Sandra J. Kegley Jan 2008

Biology Of Dendroctonus Murrayanae (Coleoptera: Curculionidae: Scolytinae) In Idaho And Montana And Comparative Taxonomic Notes, Malcolm M. Furniss, Sandra J. Kegley

Entomology Papers from Other Sources

We studied the biology of Dendroctonus murrayanae Hopkins (Coleoptera: Curculionidae: Scolytinae) in lodgepole pine, Pinus contorta Douglas, in Idaho and Montana. The beetle was not a primary agent of tree mortality. Susceptible host trees were physically damaged, had thin foliage, or were otherwise predisposed to infestation. Beetles attacked individual trees, not in groups, near ground level and at low density. Life stages and their behavior are described. Egg galleries were constructed upward and usually had short spurs. Mating occurred in the egg gallery. Eggs were laid in an elongated group, not in niches, in a shallow excavation along only one …

The Role Of Spiders In The Detrital Food Web Of An Eastern Deciduous Forest, Erin Elizabeth Hladilek Jan 2008

The Role Of Spiders In The Detrital Food Web Of An Eastern Deciduous Forest, Erin Elizabeth Hladilek

University of Kentucky Doctoral Dissertations

Historically, terrestrial food web research has focused on describing the structure of aboveground grazing webs, and determining how interactions among plants, herbivores and higher trophic levels influence primary productivity. Detrital food webs however, play a significant role in regulation of ecosystem dynamics through direct impacts on decomposition. Unraveling the complex nature of detrital food web structure is critical to developing a better understanding of ecosystem function. Therefore the primary objective of this research was to describe the structure of the leaf-litter food web in a temperate deciduous forest, with emphasis on interactions between a community of generalist predators, the forest-floor …

First Come, First Serve: “Sit And Wait” Behavior In Dung Beetles At The Source Of Primate Dung, Jennifer Jacobs, Ines Nole, Susanne Palminteri, Brett C. Ratcliffe Jan 2008

First Come, First Serve: “Sit And Wait” Behavior In Dung Beetles At The Source Of Primate Dung, Jennifer Jacobs, Ines Nole, Susanne Palminteri, Brett C. Ratcliffe

Department of Entomology: Faculty Publications

Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) compete intensively for dung resources, and most species forage in the understory. Here, we describe the unique behavior of one dung beetle species, Canthon aff. quadriguttatus (Olivier), associated with two species of monkeys from Peru. We observed this beetle species on the genital and anal regions of the brown titi monkey, Callicebus brunneus (Wagner), and subsequently falling with dung as the monkeys defecated. The same association was also observed with the bald-faced saki monkey, Pithecia irrorata irrorata (Gray). Using the “sit and wait” at the source behavior, C. quadriguttus may arrive first at the dung …

A 1 (1): 1 Atmosphere, C. J. Peterson

Midsouth Entomologist

In his 1995 novel Microserfs, Douglas Coupland describes what it means to be “one-point-oh”: the first to do something really new and cool. In the book, Coupland’s computer coder characters leave the security of software giant Microsoft to start a new company and launch their own new and cool software; a version 1.0. The same atmosphere of one-point-oh can apply to the launch of a new journal. Perhaps it can be called a Volume 1, Number 1, Page 1 atmosphere, or 1(1):1. How exactly that should be pronounced in a cool one-point-oh way I’ll leave up to you. Either way, …

A Survey Of Imported Fire Ant (Hymenoptera: Formicidae), Species And Social Forms Across Four Counties In East-Central Mississippi, T. O. Menzel, D. C. Cross, J. Chen, M. A. Caprio Jan 2008

A Survey Of Imported Fire Ant (Hymenoptera: Formicidae), Species And Social Forms Across Four Counties In East-Central Mississippi, T. O. Menzel, D. C. Cross, J. Chen, M. A. Caprio

Midsouth Entomologist

Molecular technology allows researchers to definitively identify red imported fire ants as either monogyne or polygyne based on the alleles present at the single gene Gp-9. This technique has not previously been applied to hybrid individuals of the red and black imported fire ants. Specimens were collected from 81 imported fire ant colonies from 27 locations over a four county area within the imported fire ant hybrid zone in east-central Mississippi. Gas chromatograph analysis of cuticular hydrocarbons and venom alkaloids was used to determine the species or species hybrid status of all colonies. Polymerase chain reaction (PCR) was used to …

Resource Heterogeneity Moderates The Biodiversity-Function Relationship In Real World Ecosystems, Jason M. Tylianakis, Tatyana A. Rand, Ansgar Kahman, Alexandra-Maria Klein, Nina Buchmann, Jörg Perner, Teja Tscharntke Jan 2008

Resource Heterogeneity Moderates The Biodiversity-Function Relationship In Real World Ecosystems, Jason M. Tylianakis, Tatyana A. Rand, Ansgar Kahman, Alexandra-Maria Klein, Nina Buchmann, Jörg Perner, Teja Tscharntke

Entomology Papers from Other Sources

Numerous recent studies have tested the effects of plant, pollinator, and predator diversity on primary productivity, pollination, and consumption, respectively. Many have shown a positive relationship, particularly in controlled experiments, but variability in results has emphasized the context-dependency of these relationships. Complementary resource use may lead to a positive relationship between diversity and these processes, but only when a diverse array of niches is available to be partitioned among species. Therefore, the slope of the diversity-function relationship may change across differing levels of heterogeneity, but empirical evaluations of this pattern are lacking. Here we examine three important functions/properties in different …

Aquatic Macroinvertebrates Collected From Thirty-Two Missouri Ozark Streams, George L. Harp, Phoebe A. Harp, Samuel B. Mccord Jan 2008

Aquatic Macroinvertebrates Collected From Thirty-Two Missouri Ozark Streams, George L. Harp, Phoebe A. Harp, Samuel B. Mccord

Journal of the Arkansas Academy of Science

A previously reported study of the distribution and status of an endemic dragonfly in Missouri emphasized data collected by aerial netting and examination of specimens housed in the Wilbur Enns Museum of Entomology. Dip net samples were also taken, however, to find naiads of the target species at sites where adults might not have been found and to determine whether there were associated species. Forty-one collections were made in 32 Ozark streams between mid-May and early June 1999-2000. Of the 372 taxa identified, Psephenus herricki was the most frequently associated species. Six of the 32 streams either had not been …

Using Ninhydrin To Detect Gravesoil, David O. Carter, David Yellowlees, Mark Tibbett Jan 2008

Using Ninhydrin To Detect Gravesoil, David O. Carter, David Yellowlees, Mark Tibbett

Department of Entomology: Faculty Publications

Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period …

Sugar Feeding In Adult Stable Flies, David B. Taylor, Dennis R. Berkebile Jan 2008

Sugar Feeding In Adult Stable Flies, David B. Taylor, Dennis R. Berkebile

Department of Entomology: Faculty Publications

Adult stable flies (Stomoxys calcitrans L.) are known to feed readily on sugars in the laboratory. However, little is known concerning the extent of stable fly sugar feeding in wild populations. We examined the frequency of sugar feeding in stable flies collected on Alsynite sticky traps in rural and urban environments. In addition, stable flies were visually examined to determine whether blood was present in the gut. In laboratory studies, sugars were detectable with the anthrone technique in stable flies for ~3 d after being imbibed, and blood could be visually detected in the gut for 24-48 h after …
