Two Species Of Cecidomyiidae Predacious On Citrus Rust Mite, Phyllocoptruta Oleivora, On Florida Citrus, Raul T. Villanueva, Raymond Gagne, Carl Childers

USDA Systematic Entomology Laboratory

Larvae of two undescribed species of Cecidomyiidae (Diptera) were found preying upon Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae) on Florida citrus. Identifications to genus were made from adults reared in the laboratory. The two species had distinctive larval coloration. One larval type was completely yellow and was identified as Feltiella n. sp., while the second larval type had an orange color with a transverse white band close to the mouthparts. The latter cecidomyiid was identified as belonging to a genus near Lestodiplosis in the broad sense. Feltiella n. sp. (n = 17) and the species near the genus Lestodiplosis ( …

Effect Of Bacillus Thuringiensis Cry3bb1 Protein On The Feeding Behavior And Longevity Of Adult Western Corn Rootworms (Coleoptera: Chrysomelidae), Timothy M. Nowatski, Xugou Zhou, Lance J. Meinke, Ty Vaughn, Blair Siegfried

Department of Entomology: Faculty Publications

The first transgenic corn hybrids expressing the Bacillus thuringiensis (Bt) Cry3Bb1 protein to control corn rootworm (Diabrotica spp.) larvae were registered for commercial use in 2003. This study was conducted to investigate the effect of Cry3Bb1 protein in combination with a cucurbitacin bait on adult feeding and longevity of both organophosphate-resistant and -susceptible western corn rootworms, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae). In choice and no-choice tests, possible repellency to the Bt protein was quantified by comparing beetle consumption of cellulose disks treated with three concentrations of Bt in combination with a feeding stimulant (Invite EC) to disks treated …

Phylogenetic Approach To The Study Of Triatomines (Triatominae, Heteroptera) = Abordagem Filogenética Em Triatomíneos (Triatominae, Heteroptera), Ester Tartarotti, M. T. V. Azeredo-Oliveira, C. R. Ceron

Harold W. Manter Laboratory of Parasitology: Library Materials

Abstracts

Triatomines are insects belonging to the Hemiptera order, Heteroptera suborder, Reduviidae family and Triatominae subfamily. All members of this subfamily are hematophagous. Triatomines evolved from Reduviidae predators and they are probably polyphyletic in origin. The combination of anatomical, physiological and ethological factors observed in this group, as well as the plesiomorphic and apomorphic characters that differentiate the five tribes and fourteen triatomine genera reinforce the polyphiletic hypotesis. However if we consider the five groups of triatomines, the Rhodniini, Cavernicolini, Bolboderini, Linshcosteini and Alberproseniini tribes constitute monophyletic groups, while the Triatomini tribe is considered polyphyletic. The New World is the …

Microbial Decomposition Of Skeletal Muscle Tissue (Ovis Aries) In A Sandy Loam Soil At Different Temperatures, David O. Carter, Mark Tibbett

Department of Entomology: Faculty Publications

A laboratory experiment was conducted to determine the effect of temperature (2, 12, 22 °C) on the rate of aer­obic decomposition of skeletal muscle tissue (Ovis aries) in a sandy loam soil incubated for a period of 42 days. Measurements of decomposition processes included skeletal muscle tissue mass loss, carbon dioxide (CO₂) evo­lution, microbial biomass, soil pH, skeletal muscle tissue carbon (C) and nitrogen (N) content and the calcula­tion of metabolic quotient (qCO₂). Incubation temperature and skeletal muscle tissue quality had a significant effect on all of the measured process rates with 2 °C …

Pyemotes Herfsi (Acari: Pyemotidae), A Mite New To North America As The Cause Of Bite Outbreaks, Alberto B. Broce, Ludek Zurek, James A. Kalisch, Robert Brown, David L. Keith, David Gordon, Janis Goedeke, Cal Welbourn, John Moser, Ronald Ochoa, Eduardo Azziz-Baumgartner, Fuyuen Yip, Jacob Weber

Department of Entomology: Faculty Publications

High incidences of red, itching, and painful welts on people in the midwestern United States led to the discovery of a European species of mite, Pyemotes herfsi (Oudemans) (Acari: Pyemotidae), preying on gall-making midge larvae on oak leaves. The mites' great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.

Effect Of Investigator Disturbance In Experimental Forensic Entomology: Succession And Community Composition, G. D. De Jong, W. W. Hoback

Department of Entomology: Faculty Publications

Carrion insect succession studies have historically used repeated sampling of single or a few carcasses to produce data, either weighing the carcasses, removing a qualitative subsample of the fauna present, or both, on every visit over the course of decomposition and succession. This study, conducted in a set of related experimental hypotheses with two trials in a single season, investigated the effect that repeated sampling has on insect succession, determined by the number of taxa collected on each visit and by community composition. Each trial lasted at least 21 days, with daily visits on the first 14 days. Rat carcasses …

Creating & Evaluating Artificial Domiciles For Bumble Bees, Douglas A. Golick, Marion D. Ellis, Brady Beecham

Department of Entomology: Faculty Publications

Most biologists agree that the availability of suitable nesting sites is a limiting factor for bumble bee populations (Free, 1959). Bumble bees always select areas with preexisting insulation for nesting. Fur-lined abandoned rodent dens are especially attractive, but occasionally, abandoned man-made materials are inhabited. It is not rare to find multiple dead queens in a nest indicating that they have fought for ownership.

Despite our knowledge of bumble bee nest site selection, most efforts to attract bumble bees to artificial domiciles have been met with limited success (Fye & Medler, 1954; Hobbs et al.,1960). Creating and evaluating artificial domiciles provides …

Assessing Risk Of Resistance To Aerial Applications Of Methyl-Parathion In Western Corn Rootworm (Coleoptera: Chrysomelidae), Michael A. Caprio, Tim Nowatski, Blair Siegfried, Lance J. Meinke, Robert J. Wright, Larry D. Chandler

Department of Entomology: Faculty Publications

We validated a stochastic model of the evolution of resistance to adulticidal sprays of methyl-parathion in western corn rootworm, Diabrotica virgifera virgifera LeConte, populations in Nebraska. The population dynamics predicted by the model resembled that reported for field populations, and time until control failures occurred closely matched reports by commercial crop consultants. We incorporated uncertainty about the values used for 18 model parameters by replacing default values with random draws taken from a normal distribution. One parameter, the initial resistance allele frequency, was no longer measurable because of the evolution of resistance. We therefore proposed five candidate initial allele frequencies …

Inheritance Of Resistance To The Cry1ab Bacillus Thuringiensis Toxin In Ostrinia Nubilalis (Lepidoptera: Crambidae), Analiza P. Alves, Terrence A. Spencer, B.E. Tabashnik, Blair Siegfried

Department of Entomology: Faculty Publications

Laboratory selection with Cry1Ab, the predominant Bacillus thuringiensis (Bt) toxin in transgenic corn, Zea mays L., produced >1000-fold resistance in two laboratory strains of European corn borer, Ostrinia nubilalis (Hubner). We tested the offspring of various crosses to determine the mode of inheritance of resistance to Cry1Ab. Patterns of inheritance of resistance were similar in the two resistant strains. The progeny of reciprocal F₁ crosses (resistant male x susceptible female and vice versa) responded alike in bioassays, indicating autosomal inheritance. The median lethal concentrations (LC₅₀ values) of F₁ were intermediate between the resistant and susceptible parents, indicating …

Movement Of Cicindela Hirticollis Say Larvae In Response To Moisture And Flooding, Mathew L. Brust, William Wyatt Hoback, Kerri Farnsworth Skinner, Charles Barry Knisley

Department of Entomology: Faculty Publications

The larvae of the tiger beetle, Cicindela hirticollis Say, inhabit sandy shoreline areas that flood periodically. This species has declined over much of its range and at least one subspecies is near extinction, possibly as a result of human alteration of waterways. In addition to physiological tolerance for anoxia, the larvae have physical and behavioral adaptations to avoid drowning. We hypothesized that C. hirticollis larvae would exhibit behavioral responses to soil moisture change and flooding because, unlike most other tiger beetles, they frequently relocate their burrows. Our laboratory studies demonstrated that larvae select surface soil moisture levels of 7–50% saturation …

Distribution And Biology Of The Ectoparasitic Beaver Beetle Platypsyllus Castoris Ritsema In North America (Coleoptera: Leiodidae: Platypsyllinae), Stewart B. Peck

Insecta Mundi

The distribution and biology of the beaver beetle, Platypsyllus castoris Ritsema, are summarized for North America. In light of the fact that the beetle uses two beaver species as hosts which have seemingly been separated for some five million years on two continents, it is asked if the Nearctic and Palearctic beetle populations are really the same species.

An Annotated Checklist Of Wisconsin Sap And Short-Winged Flower Beetles (Coleoptera: Nitidulidae, Kateretidae), Michele B. Price, Daniel K. Young

Insecta Mundi

A survey of Wisconsin Nitidulidae and Kateretidae yielded 78 species through analysis of literature records, museum and private collections, and three years of field research (2000-2002). Twenty-seven species (35% of the Wisconsin fauna) represent new state records, having never been previously recorded from the state. Wisconsin distribution, along with relevant collecting techniques and natural history information, are summarized. The Wisconsin nitidulid and kateretid faunae are compared to reconstructed and updated faunal lists for Illinois, Indiana, Michigan, Minnesota, Ohio, and south-central Canada. Literature and distributional records suggest at least 11 additional nitidulid species may occur in Wisconsin.

Physiological Responses Of Resistant And Susceptible Buffalograsses To Blissus Occiduus (Hemiptera: Blissidae) Feeding, Tiffany Heng-Moss, Tulio Macedo, Lisa Franzen-Castle, Frederick P. Baxendale, Leon G. Higley, Gautam Sarath

Department of Entomology: Faculty Publications

The impact of Blissus occiduus Barber feeding on resistant (‘Prestige’) and susceptible (‘378’) buffalograsses, Buchloe dactyloides (Nuttall) Engelmann, was evaluated through measurement of carbon exchange rate, light and carbon assimilation (A-C) curves, chlorophyll a fluorescence, and nonstructural carbohydrates. No significant differences in carbon exchange rates were observed between infested and control plants for 378 at 5 and 10 d after infestation; however, at 20 d after chinch bug introduction, significant differences in carbon exchange rates between infested and control 378 plants were detected. Carbon exchange rates were similar between infested and control Prestige plants at 5, 10, and 20 d …

Evaluation Of Cool- And Warm-Season Grasses For Resistance To Multiple Chinch Bug (Hemiptera: Blissidae) Species, Wyatt G. Anderson, Tiffany Heng-Moss, Frederick P. Baxendale

Department of Entomology: Faculty Publications

Chinch bugs are common pests of many agronomic and horticulturally important crops and turfgrasses. The extensive overlap of plant hosts and geographic distribution of Blissus leucopterus leucopterus (Say), Blissus leucopterus hirtus Montandon, Blissus insularis Barber, and Blissus occiduus Barber underscores the importance of identifying resistant germplasm. Cool- and warm-season turfgrasses and sorghum, Sorghum bicolor (L.) Moench, were evaluated for resistance to chinch bugs in the Blissus complex, and the presence of multiple resistance was documented. Greenhouse studies established that B. occiduus-resistant (‘Prestige’, formerly NE91-118) and -susceptible (‘378’) buffalograsses, , Buchloe dactyloides (Nuttall) Engelmann, were susceptible to all other chinch …
