Natural Distribution Of Parasitoids Of Larvae Of The Fall Armyworm, Spodoptera Frugiperda, In Argentina, M Gabriela Murua, Jamie Molina Ochoa, Patricio Fidalgo

Department of Entomology: Faculty Publications

Abstract To develop a better understanding of the natural distribution of the fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), and to update the knowledge of the incidence of its complex of parasitoids. S. frugiperda, samplings in whorl-stage corn were carried out in provinces of Argentina from 1999 to 2003. S. frugiperda larvae were collected from corn in localities of the provinces of Tucumán, Salta, Jujuy, Santiago del Estero, La Rioja, Córdoba, San Luis, Chaco and Misiones. In each locality 30 corn plants were sampled and only larvae located in those plants were collected. The parasitoids that emerged from S. …

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 …

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 …

Gene Expression Profiling Of Tolerant Barley In Response To Diuraphis Noxia (Hemiptera: Aphididae) Feeding, A. Gutsche, Tiffany Heng-Moss, Gautam Sarath, P. Twigg, Y. Xia, G. Lu, D. Mornhinweg

Department of Entomology: Faculty Publications

Aphids are, arguably, the single most damaging group of agricultural insect pests throughout the world. Plant tolerance, which is a plant response to an insect pest, is viewed as an excellent management strategy. Developing testable hypotheses based on genome-wide and more focused methods will help in understanding the molecular underpinnings of plant tolerance to aphid herbivory. As a first step in this process, we undertook transcript profiling with Affymetrix GeneChip Barley Genome arrays using RNA extracted from tissues of tolerant and susceptible genotypes collected at three hours, three days and six days after Diuraphis noxia introduction. Acquired data were compared …

Adaptation And Invasiveness Of Western Corn Rootworm: Intensifying Research On A Worsening Pest, Michael E. Gray, Thomas W. Sappington, Nicholas Miller, Joachim Moeser, Martin O. Bohn

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is an established insect pest of maize (Zea mays L.) in North America. The rotation of maize with another crop, principally soybeans, Glycine max (L.), was the primary management strategy utilized by North American producers and remained highly effective until the mid-1990s. In 1995, widespread and severe root injury occurred in east-central Illinois and northern Indiana maize fields that had been annually rotated with soybeans on a regular basis for several decades. The failure of this cultural tactic from a pest management perspective was attributed to a behavioral adaptation by a …

Expressed Sequence Tags From Larval Gut Of The European Corn Borer (Ostrinia Nubilalis): Exploring Candidate Genes Potentially Involved In Bacillus Thuringiensis Toxicity And Resistance, Chitvan Khajuria, Yu Cheng Zhu, Ming-Shun Chen, Lawrent L. Buschman, Randall A. Higgins, Jianxiu Yao, Andre Lb Crespo, Blair D. Siegfried, Subbaratnam Muthukrishnan, Kun Yan Zhu

Department of Entomology: Faculty Publications

Background: Lepidoptera represents more than 160,000 insect species which include some of the most devastating pests of crops, forests, and stored products. However, the genomic information on lepidopteran insects is very limited. Only a few studies have focused on developing expressed sequence tag (EST) libraries from the guts of lepidopteran larvae. Knowledge of the genes that are expressed in the insect gut are crucial for understanding basic physiology of food digestion, their interactions with Bacillus thuringiensis (Bt) toxins, and for discovering new targets for novel toxins for use in pest management. This study analyzed the ESTs generated from the larval …
