Taxonomic Redefinition Of The Genera Parataenius Balthasar And Pseudataenius Brown, With Descriptions Of Three New Species (Scarabaeidae: Aphodiinae: Eupariini), Z. Teresa Stebnicka, Paul E. Skelley

Insecta Mundi

The New World euparine scarab genera Parataenius Balthasar, 1961 and Pseudataenius Brown, 1927 are revised. Ataenius brunneus Schmidt is transferred to the genus Parataenius becoming Parataenius brunneus (Schmidt), new combination. The monospecific genus Ataenioides Petrovitz, 1973, is synonymized with Pseudataenius Brown, 1927, (new synonymy) and the type species, Ataenioides gracilitarsis Petrovitz, is given the new combination Pseudataenius gracilitarsis (Petrovitz). New species of Parataenius are described from southern South America: Parataenius selvae, P. estero, and P. martinezi. Keys for species of both genera are presented and pertinent morphological details are illustrated.

Larra BicolorFabricius (Hymenoptera: Crabronidae): Its Distribution Throughout Florida, J. H. Frank, N. C. Leppla, R. K. Sprenkel, A. C. Blount, R. F. Mizell, Iii

Insecta Mundi

We document the presence of Larra bicolor Fabricius (Hymenoptera: Crabronidae) in 46 of Florida’s 67 counties. The species is represented by two stocks. The first (released in 1981) originated in Pará, Brazil, but was obtained from Puerto Rico, and became established in Broward County in southern Florida. The second (released in 1988) originated in Santa Cruz de la Sierra, Bolivia, and became established in Alachua County in northern Florida. The Bolivian stock, aided by additional satellite releases from Alachua County, is now widely distributed. The species probably occupies all counties in central and northern Florida, but may yet be absent …

Hypoxia Tolerance In Adult And Larval Cicindela Tiger Beetles Varies By Life History But Not Habitat Association, Mathew L. Brust, W. Wyatt Hoback

Entomology Papers from Other Sources

Flooding exposes terrestrial organisms to severe hypoxia. Among the best-studied insects that are frequently exposed to flooding are tiger beetle (Coleoptera: Cicindelidae) larvae. In previous studies with a limited number of species, a correlation was found between habitat and hypoxia tolerance. In the current study, we examined hypoxia tolerance among third instars of six Cicindela species that vary in habitat association; we also tested adult survival of these species. We found that larvae of the different species survived an average of between 60 and 120 h of submersion in severely hypoxic water at 20°C, with larvae that occur in dry …

Protein Digestion In Larvae Of The Red Oak Borer Enaphalodes Rufulus, Damon Crook, Sheila Prabhakar, Brenda Oppert

Entomology Papers from Other Sources

In the Ozark Mountains of the U.S.A., the red oak borer Enaphalodes rufulus contributes to the destruction of red oaks. To understand nutrient digestion in E. rufulus larvae, digestive proteinases are compared in both larvae fed heartwood phloem and those transferred to artificial diet. The pH of gut extracts is approximately 6.3 in the midgut and foregut and decreases to 5.5 in the hindgut region. The hydrolysis of casein by midgut extracts from E. rufulus larvae fed either artificial diet or phloem from tree sections increases in buffers greater than pH 6.19, with maximum hydrolysis being observed at pH 10.1. …

Supercooling Point Plasticity During Cold Storage In The Freeze-Tolerant Sugarbeet Root Maggot Tetanops Myopaeformis, Joseph Rinehart, George Yocum, Anitha Chirumamilla-Chapara, Mark Boetel

Entomology Papers from Other Sources

The sugarbeet root maggot Tetanops myopaeformis (Röder) overwinters as a freeze-tolerant third-instar larva. Although most larvae are considered to overwinter for only 1 year, some may exhibit prolonged diapause in the field. In the laboratory, they can live for over 5 years using a combination of diapause and post-diapause quiescence. In the present study, the cold survival strategies of these larvae during storage is investigated by measuring their supercooling points in combination with survival data. Supercooling points (SCPs) change significantly during storage, highlighted by a marked increase in the range of SCPs recorded, although the ability to tolerate freezing is …

Species Richness And Host Associations Of Lepidoptera-Attacking Tachinidae In The Northeast Ecuadorian Andes, John O. Stireman Iii, Harold F. Greeney, Lee A. Dyer

Biological Sciences Faculty Publications

Most of the unknown biological diversity of macro-organisms remaining to be discovered and described lies in the tropical regions of the world and consists primarily of insects. Those insects with parasitoid lifestyles constitute a significant portion of insect diversity, yet parasitoids are among the most poorly known of major insect guilds in the humid tropics. Here we describe and analyze the richness of one diverse taxon of parasitoids, flies in the family Tachinidae, reared from Lepidoptera as part of a biological survey of Lepidoptera and their parasitoids in one mid-elevation (2000 m) area in the northeast Ecuadorian Andes. One hundred …

2008 Soybean Insect Losses For Mississippi And Tennessee, F. R. Musser

Midsouth Entomologist

Survey-based soybean insect losses provide a glimpse of current soybean management practices and allow one to see evolving trends. Continuing a survey begun in 2004 in Mississippi, the 2008 survey showed that seed treatments were used extensively for the first time and soybean acreage monitored by crop scouts continued to increase. Stink bugs (Hemiptera: Pentatomidae) remained the most important pest in Mississippi followed by soybean looper (Lepidoptera: Noctuidae), bean leaf beetle (Coleoptera: Chrysomelidae) and threecornered alfalfa hopper (Hemiptera: Membracidae). In the first year of published losses for Tennessee, economic costs in yield loss plus control costs were greatest for stink …

Bioavailability Of Chlorantraniliprole And Indoxacarb To Eastern Subterranean Termites (Isoptera: Rhinotermitidae) In Various Soils, Neil A. Spomer, Shripat T. Kamble, Blair D. Siegfried

Department of Entomology: Faculty Publications

A laboratory study was conducted to determine the toxicity of indoxacarb and chlorantraniliprole to Eastern subterranean termites, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae) resulting from topical applications and exposure to treated soil. Soils with varying organic matter (0.57-3.64%) and chemical characteristics were used in termiticide bioassays. Lethal dose resulting from topical application indicated that chlorantraniliprole was two- to 11-foldmoretoxic than indoxacarb. Lethal concentration assays yielded opposite results where concentrations of indoxacarb in soil that caused either 50 or 90% mortality of R. flavipes workers at 48 and 144 h were two- to six-fold lower than chlorantraniliprole. The bioavailability of indoxacarb and …

European Populations Of Diabrotica Virgifera Virgifera Are Resistant To Aldrin, But Not To Methyl-Parathion, M. Ciosi, S. Toepfer, H. Li, T. Haye, U. Kuhlmann, Haichuan Wang, Blair D. Siegfried, T. Guillemaud

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a major pest of cultivated corn in North America and has recently begun to invade Europe. In addition to crop rotation, chemical control is an important option for D. v. virgifera management. However, resistance to chemical insecticides has evolved repeatedly in the USA. In Europe, chemical control strategies have yet to be harmonized and no surveys of insecticide resistance have been carried out. We investigated the resistance to methyl-parathion and aldrin of samples from nine D. v. virgifera field populations originating from two European outbreaks thought to have originated …

Apparent Hybridization Between Trimerotropis Agrestis And Trimerotropis Maritima (Orthoptera: Acrididae) In A Recently Disturbed Habitat, Mathew L. Brust, W. Wyatt Hoback, Robert J. Wright

Department of Entomology: Faculty Publications

In Nebraska, the ranges of Trimerotropis maritima (eastern species) and T. agrestis (western species) overlap but populations usually remain separated by habitat preferences. The morphological and color differences between the species are described. However, around Lake McConaughy, a reservoir on the North Platte River which has declined markedly in depth as a result of recent drought, a habitat was created in which the two species coincide and hybridize frequently. The water level in this reservoir had dropped in excess of 20 meters as of 2007, resulting in large expanses of dunes grading into beach habitats. Grasshoppers were collected in the …

Taxonomy Of Janetiella Thymi (Kieffer) (Diptera: Cecidomyiidae) And Of The Species Formerly In Janetiella That Feed On Vitis (Vitaceae), Raymond Gagne

USDA Systematic Entomology Laboratory

The poorly known European species Janetiella thymi (Kieffer), type species ofJanetiella Kieffer (Diptera: Cecidomyiidae), is redescribed. Gall makers on grape that were formerly placed in Janetiella are shown to be distinct from that genus and transferred to Vitisiella Fedotova & Kovalev, a genus recently erected for a species on grape in Siberia. Among the distinguishing traits of Vitisiella, more fully characterized here than previously, are the closed costal vein at its juncture with R5, the deeply divided male hypoproct, and the conspicuous dorsolateral sclerites of the ovipositor. Janetiella brevicauda Felt, also redescribed, and Cecidomyia oenephila Haimhoffen, both previously …

A New Filatima Busck (Lepidoptera: Gelechiidae) Associated With Lupine And Early Herbivore Colonization On Mount St. Helens, David Adamski, Jennifer L. Apple, John G. Bishop

USDA Systematic Entomology Laboratory

Filatima loowita, n. sp. is described from the Pumice Plain on Mount St. Helens in Washington, United States. An apparent specialist on lupine, early instars feed as leaf-miners, while later instars tie leaflets together into silken tunnels and feed externally, mainly on the leaf tissue. The larvae make webbed tunnels, which extend from the root bundles to the uppermost leaves of the plant. Illustrations are provided of the adult male and female genitalia, and chaetotaxal maps of the last-instar larva, supplemented with scanning electron micrographs and images of the host on the volcano.

A New Holcocera Clemens From Guatemala And Redescription Of H. Iceryaeella (Riley) From The United States (Lepidoptera: Coleophoridae: Blastobasinae: Holcocerini): Two Congeners With Incidental Preference For Avocado, David Adamski, Mark Hoddle

USDA Systematic Entomology Laboratory

Two species of Holcocera Clemens (Lepidoptera: Coleophoridae: Blastobasinae: Holcocerini) are known to feed on Persea americana Mill. (Lauraceae), but their frequency of infestation appears low. One species, Holcocera plagatola, n. sp., from Guatemala, is described herein. Holcocera iceryaeella (Riley) is known only from California and has been recorded on many different host plants; it is also known to be a predator of immature Hemiptera and scale insects. Photographs of the imagos of both Holcocera species are included, in addition to illustrations of the male and female genitalia. We comment on host preferences for both species.

Not All Oak Gall Wasps Gall Oaks: The Description Of Dryocosmus Rileypokei, A New, Apostate Species Of Cynipini From California, Matthew L. Buffington, Shelah I. Morita

USDA Systematic Entomology Laboratory

Cynipini gall wasps (Hymenoptera: Cynipidae) are commonly known as oak gall wasps for their almost exclusive use of oak (Quercus spp.; Fagaceae) as their host plant. Previously, only three of the nearly 1,000 species of Cynipini have been recorded from hosts other than Quercus. These three are known from western chinquapin (Chrysolepis), chestnut (Castanea) and tan bark oak (Lithocarpus), all lineages of Fagaceae related to Quercus. Here we describe Dryocosmus rileypokei Morita & Buffington, new species, a second species of cynipine which attacks Chrysolepis. Unlike the previously known gall wasp …

Description, Circumscription And Phylogenetics Of The New Tribe Zaeucoilini (Hymenoptera: Figitidae: Eucoilinae), Including A Description Of A New Genus, Matthew L. Buffington

USDA Systematic Entomology Laboratory

Neotropical eucoiline genera that have been included in and allied with the Zaeucoila genus group are redescribed. Following character analysis and phylogenetic reconstruction (25 taxa, 96 morphological characters, 1452 ribosomal and mitochondrial characters), this informal genus group was found to be monophyletic, and hence raised to formal recognition as a tribe of eucoilines, namely Zaeucoilini new tribe. Through phylogenetic reconstruction, Aegeseucoela Buffington was determined to be polyphyletic; the type species of Aegeseucoela, A. grenadensis (Ashmead), is transferred to Agrostocynips comb.n.; the orphaned species, A. flavotincta (Kieffer), is transferred to Marthiella Buffington gen.n., comb.n. Based on the …

Data Publication And Dissemination Of Interactive Keys Under The Open Access Model, Lyubomir Penev, Michael Sharkey, Terry Erwin, Simon Van Noort, Matthew Buffi Ngton, Katja Seltmann, Norman Johnson, Matt Taylor, F. Christian Th Ompson, Michael J. Dallwitz

Revision Of The Ant Genus Crematogaster (Hymenoptera: Formicidae) In North America, Cynthia Ellen Morgan

Open Access Theses & Dissertations

The natural history of thirty-eight species of the genus Crematogaster in North America has been discussed and distribution of specimens mapped. A dichotomous key to the workers of these species has been developed. I hypothesized that the species richness is not as great as previously thought in North America. A taxonomic review of these species has been made with the following changes:

Crematogaster cerasi Fitch 1855 senior synonym of C. browni Buren1968.

C. coarctata Mayr 1870 senior synonym of C. californica Emery 1895, C. mormonum

Systematics Of Ichneutine Parasitic Wasps (Braconidae: Ichneutinae), John Ray Fischer

Theses and Dissertations--Entomology

Ichneutine wasps have received little attention, despite their hypothesized placement at the base of an economically and ecologically important clade, the Microgastroidia s.s. This study combines previous hypotheses based on morphology with molecular evidence from multiple genes (28S: D1-5, 18S, COI, and CAD) to examine phylogenetic relationships of Ichneutinae using maximum parsimony and Bayesian inference. The three main ichneutine groups (Ichneutini, Muesebeckiini, and Proteropini) are each found to be monophyletic, but evidence exists that Ichneutinae itself is paraphyletic with respect to the rest of Microgastroidea s.l. Lispixys is found to be derived from within Oligoneurus, and Masonbeckia is almost …

Examination Of The Internal Morphology Of The Ixodid Tick, Amblyomma Maculatum Koch, (Acari: Ixodidae); A “How-To” Pictorial Dissection Guide, K. T. Edward, J. Goddard, A. S. Varela-Stokes

Midsouth Entomologist

There is inadequate documentation of how to dissect ticks, a process required for many tick and disease studies. While the literature may contain numerous line drawings and instructions describing the process, none is adequate for the novice tick dissector. We present a “how-to” description and pictorial essay outlining our approach to tick dissection. The ticks used in this study were adult male and female Gulf Coast ticks, Amblyomma maculatum Koch, though the methods described herein could be applied to any species. None of the A. maculatum specimens we dissected adequately demonstrated ovaries, so we used one female A. americanum L.tick …
