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.

Diel Periodicity In The Production Of Green Leaf Volatiles By Wild And Cultivated Host Plants Of Stemborer Moths, Chilo Partellus And Busseola Fusca, K. Chamberlain, Z. R. Khan, J. A. Pickett, T. Toshova, L. J. Wadhams

All Peer-Reviewed Publications

The volatile chemicals produced by four poaceous plant species, blue thatching grass, Hyparrhenia tamba, Napier grass, Pennisetum purpureum, sorghum, Sorghum bicolor, and maize, Zea mays, which are host plants for the lepidopterous stemborers, Chilo partellus and Busseola fusca, were collected by air entrainment and analyzed by gas chromatography. The total quantities of volatiles collected hourly, over a 9-hr period, from P. purpureum and H. tamba showed an approximately hundredfold increase in the first hour of the scotophase. Thereafter, the amount decreased rapidly to levels present during photophase. Although onset of scotophase also triggered an increase in quantities of volatiles collected …

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 …

Woy '06: Spicebush Provides A Salad Bar To Some Caterpillars, W. John Hayden

Biology Faculty Publications

While many wildflower enthusiasts appreciate spicebush (Lindera benzoin), the 2006 Virginia Wildflower of the Year, for its subtle beauty, plant ecologists have found this humble shrub to be a fruitful subject for scientific inquiry. The notes that follow relay just a few of the interesting nuggets that can be gleaned from a cursory study of the scientific literature about this plant.

Reproductive Isolation And Differentiation Between Five Populations Of Cotesia Plutellae (Hymenoptera: Braconidae), Parasitoid Of Plutella Xylostella (Lepidoptera: Plutellidae), Claudia Rincon, Dominique Bordat, Bernhard Löhr, Stéphane Dupas

All Peer-Reviewed Publications

Many taxa used in biological control may be composed of several population units reproductively isolated to various degrees. Yet, the introductions of non-compatible populations may result in a depression of intended biological control. Cotesia plutellae has been widely used as a biological control agent of the diamondback moth, Plutella xylostella. However, not all introductions and augmentations were successful. With the aim to develop markers of compatibility for this species, we studied the reproductive compatibility between five populations (South Africa, Benin, Martinique, Reunion, and Taiwan) and analyzed its statistical relationship with three morphological characters (antennae and body length and antennae/body ratio), …

Interspecific Competition Between Xanthopimpla Stemmator Thunberg And Dentichasmias Busseolae Heinrich (Hymenoptera: Ichneumonidae), Pupal Parasitoids Attacking Chilo Partellus (Lepidoptera: Crambidae) In East Africa, Benjamin K. Muli, Fritz Schulthess, Rosebella O. Maranga, Helen L. Kutima, Nanqing Jiang

All Peer-Reviewed Publications

Interspecific competition between Xanthopimpla stemmator and Dentichasmias busseolae was studied using pupae of the invasive crambid stemborer Chilo partellus as the host. While X. stemmator is an old association, D. busseolae formed a relatively new association with C. partellus in East Africa. Two different time intervals between parasitism (0 and 48 h) and two parasitoid sequences [i.e., X. stemmator before D. busseolae (Xs-Db) and D. busseolae before X. stemmator (Db-Xs)] were chosen. In addition, the parasitoids' performance on pupae in maize stems and ears was assessed. For both X. stemmator and D. busseolae, there was no difference in foraging time …

Stability And Persistence Of Aldrin And Methyl-Parathion Resistance In Western Corn Rootworm Populations (Coleoptera: Chrysomelidae), Srinivas Parimi, Lance J. Meinke, B. Wade French, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

The susceptibilities of laboratory and field-collected western corn rootworm populations (Diabrotica virgifera virgifera LeConte) to methyl-parathion and aldrin were estimated by topical application of insecticide during 2002 to determine the stability of resistance in the absence of selective pressures. Most of the laboratory-reared and field-collected populations were significantly resistant to both insecticides. Average LD ₅₀ values of laboratory and field-collected populations were 19- and 13-fold greater than the susceptible population in methyl-parathion bioassays, respectively, and 204- and 125-fold greater in the aldrin bioassays, respectively. The presence of aldrin and methyl-parathion resistance in field-collected populations strongly suggests that both resistance …

Rediscovery And Redescription Of The Remarkable Phoenicus Sanguinipennis Lacordaire (Coleoptera: Cerambycidae: Trachyderini) From The Dominican Republic, Steven Lingafelter, Eugenio Nearns

USDA Systematic Entomology Laboratory

Phoenicus sanguinipennis was described by Lacordaire in 1869 based on one male specimen of unknown origin. We rediscovered this species 135 years later in the Punta Cana region in La Altagracia Province of eastern Dominican Republic (18°30.477’N, 68°22.499’W). Twenty-seven specimens were collected at lights and on dead Maclura tinctoria (Linnaeus) D. Don ex Steudel (Moraceae). We provide a thorough description of the species and the previously unknown female, and a discussion of the previous and current knowledge of the species.

County-Level Surveillance Of White-Tailed Deer Infestation By Ixodes Scapularis And Dermacentor Albipictus (Acari: Ixodidae) Along The Illinois River, M. Roberto Cortinas, Uriel Kitron

Department of Entomology: Faculty Publications

From 1998 to 2003, 4,935 hunter-killed deer in northern and central Illinois were examined for ticks; 4,066 blacklegged ticks, Ixodes scapularis Say, and 6,530 winter ticks, Dermacentor albipictus (Packard) (Acari: Ixodidae), were collected. I. scapularis was the predominant tick species in the northern portion of the study area, with a decreasing north-to-south prevalence gradient. In contrast, D. albipictus was more common in the south with a decreasing south-to-north prevalence gradient. Compared with previous studies, the geographic range for both species expanded into the central portion of the Illinois River. Prevalence and intensity of both tick species were greater on bucks, …

Relative Abundance Of Exotic And Native Coccinellidae (Coleoptera) In Southeast Nebraska Alfalfa, James C. Kriz, Stephen D. Danielson, James R. Brandle, Erin E. Blankenship

Department of Entomology: Faculty Publications

The seven-spotted lady beetle, Coccinella septempunctata L., and the multicolored Asian lady beetle, Harmonia axyridis Pallas, are exotic Coccinellidae (Coleoptera) that are regularly encountered in southeastern Nebraska. Harmonia axyridis, a native of eastern Asia, was first reported in an established population near Abita Springs, St. Tammay Parish, Louisiana, in 1988. It was hypothesized that the introduction was accidental through commerce in Louisiana and not from introduction for biological control. Coccinella septempunctata, a native of Eurasia, was introduced for biological control several times and at a variety of locations across North America during the last century. As is the case …

Biomass Dynamics Of Tipula (Insecta: Diptera) In Forested Streams Of The Interior Highlands, Arkansas, Samuel B. Mccord, Alan D. Christian, Richard S. Grippo

Journal of the Arkansas Academy of Science

Abundance patterns of aquatic macroinvertebrates that utilize coarse particulate organic matter as a food source are important indicators of non--point source pollution associated with silviculture activities. This group, referred to as shredders, typically decreases in abundance as its food source—primarily leaves—is removed from the ecosystem. We tested whether larval biomass of the crane fly Tipula, a common member of the group, was an effective estimator of shredder abundance. Additionally, we used regression analysis to test whether the length to dry mass relationship of Tipula differed among geographic regions, between seasons, and between years. Results did not indicate significant differences in …

Characteristics Of Bark Beetle Infestations In East Texas During A Period Of Low Southern Pine Beetle Activity, David L. Kulhavy

Faculty Publications

The species composition nf southern pine bark beetle infestations was examined in east Texas in 1979, A total of 545 infestations were located in thirteen 18,000 acresurvey blocks. Ips spp, were observed in 98.9 of ihe infestations, with black turpentine beetles, Dendrnclonus lerebrans Olivier, present in 42.4 % ofthe infestations. Southern pine beetles, D. fronlulis Zimmemiann. were only observed in 11 infestations (2.0%), and were less abundant than other bark beetle species in these infestations. Almost 80% of the infestations were associated with a recognizable pre-disposing factor (lightning, fire, etc.). Most Infestations were small (less than six trees), though infestations …

Thermal Conditioning Of Fifth-Instar Cydia Pomonella (Lepidoptera: Tortricidae) Affects Hsp70 Accumulation And Insect Mortality, X. Yin, S. Wang, J. Tang, J. D. Hansen, S. Lurie

Entomology Papers from Other Sources

Levels of HSP70 protein of fifth-instar codling moth [Cydia pomonella (L.) (Lepidoptera: Tortricidae)] are determined after conditioning at 35 °C for different times and also after recovery at 22 °C. Protein samples from larvae conditioned for different times are separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis electrophoresis. Sub-lethal thermal conditioning at 35 °C for 40 min, 2, 6 and 18 h induces new protein bands in the extracts from treated codling moth larvae. Immunodetection with an antibody to a heat-inducible HSP70 indicates a stronger reaction after 35 °C for 2, 6 and 18 h than after 35 °C for …
