Celastrina Idella (Lycaenidae: Polyommatinae): A New Butterfly Species From The Atlantic Coastal Plain, David M. Wright, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

A new species of Polyommatinae, Celastrina idella, is described from the sandy Atlantic coastal plain of the eastern United States. It is presently known to occur from southern New Jersey through Georgia. Celastrina idella larvae have been recorded from four species of Ilex (holly). Celastrina idella is distinguished from sympatric C. ladon and C. neglecta by differences in larval host, flight period, pupal diapause, and adult size and wing characters. In the New Jersey pine barrens the butterfly is univoltine and flies in the spring between the flights of its sympatric congeners.

Hübner’S Helicta, The Forgotten Neonympha: The Recognition And Elevation Of Neonympha Helicta (Nymphalidae: Satyrinae) To Specific Status, The Designation Of Neotypes For N. Helicta And N. Areolatus, The Subspecific Transfer Of Septentrionalis To Helicta And The Description Of A Third Helicta Subspecies From South Florida, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Hübner (1806) based the name Oreas fimbriata helicta on a John Abbot painting of a southeastern United States satyr without a written description. Subsequent lepidopterists have nearly ignored this taxon. Helicta is herein recognized as a valid species–Neonympha helicta. A neotype is designated for helicta from Aiken County, South Carolina and deposited in the Allyn Museum of Entomology Sarasota, Florida. A neotype is also designated for Papilio areolata J.E. Smith, 1797 from Chatham County, Georia and deposited in the Allyn Museum of Entomology. Septentrionalis Davis, 1924 is recognized as the northern United States subspecies of helicta not areolatus …

All Peer-Reviewed Publications

Freshly deposited third instar Glossina morsitans centralis larvae were infected with the tsetse DNA virus by microinjection, and at emergence adult males were separated from the females and fed on rabbit blood every second day for 8 days. A control group treated with sterile saline were handled similarly. They were dissected, and comparative observations made on the appearance and size of the accessory reproductive glands (ARG) in infected and control males. Regularly fed 8-day-old males from infected and control groups were mated to 2-day-old normal females obtained from the insectay. After separation from copula, the females were dissected and the …

Mechanisms Of Thermal Stability During Flight In The Honeybee Apis Mellifera, Stephen P. Roberts, Jon F. Harrison

Biological Sciences Faculty Research & Creative Works

Thermoregulation of the Thorax Allows Honeybees (Apis Mellifera) to Maintain the Flight Muscle Temperatures Necessary to Meet the Power Requirements for Flight and to Remain Active Outside the Hive Across a Wide Range of Air Temperatures (T(A)). to Determine the Heat-Exchange Pathways through Which Flying Honeybees Achieve Thermal Stability, We Measured Body Temperatures and Rates of Carbon Dioxide Production and Water Vapor Loss between T(A) Values of 21 and 45°C for Honeybees Flying in a Respirometry Chamber. Body Temperatures Were Not Significantly Affected by Continuous Flight Duration in the Respirometer, indicating that Flying Bees Were at Thermal Equilibrium. Thorax Temperatures …

A New Subspecies Of Brephidium Isophthalma (Lycaenidae: Polyommatinae) From Coastal South Carolina, Harry Pavulaan, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Brephidium isophthalma pseudofea was described in 1873 from the Florida Keys, United States. The ventral ground color of the wings in topotypical pseudofea is a yellowish brown. The antennal clubs of pseudofea have prominent orange red tips. The ventral surface of the abdomen of pseudofea is broadly white to very light gray and usually extends halfway around the sides of the light to medium brown abdomen. Specimens of B. isophthalma from coastal South Carolina differ greatly from topotypical pseudofea. Accordingly, B. i. insularus is described as a new subspecies from coastal South Carolina. The antennal clubs …

Chronic Effects Of Atrazine On Tolerance Of A Benthic Diatom, Karen J. Nelson, Kyle D. Hoagland, Blair Siegfried

Department of Entomology: Faculty Publications

The effects of prior chronic exposure to atrazine on responses to subsequent acute exposures were investigated using a common benthic diatom. Clonal, axenic cultures of Craticula cuspidata were established from the Platte River (Nebraska) and obtained from a culture collection (unlikely prior exposure to atrazine). All cultures received a chronic 67-d treatment of 1 μg/L atrazine, and growth was monitored using fluorometric detection of chlorophyll a. Chronic atrazine exposure significantly reduced growth rate only during the first day of treatment (p= 0.0001); no significant effect was detected throughout the remainder of the 67-d period. Following the chronic treatment, …

Baseline Susceptibility Of European Corn Borer (Lepidoptera: Crambidae) To Bacillus Thuringiensis Toxins, Paula C. R. G. Macron, Linda J. Young, Kevin L. Steffey, Blair Siegfried

Department of Entomology: Faculty Publications

Susceptibility to CrylAb and CrylAc toxins from Bacillus thuringiensis was determined for 11 populations of neonate European corn borer, Ostrinia nubilalis (Hiibner), from the United States and 1 from northern Italy. Corn borer larvae were exposed to artificial diet treated with increasing B. thuringiensis concentrations, and mortality and growth inhibition were evaluated after 7 d. The range of variation in B. thuringiensis susceptibility indicated by growth inhibition was very similar to that indicated by mortality. Although interpopulation variation in susceptibility to both proteins was observed, the magnitude of the differences was small (54-fold) and comparable to the variability observed among …

Isolation Of Trypanosoma Brucei From The Monitor Lizard (Varanus Niloticus) In An Endemic Focus Of Rhodesian Sleeping Sickness In Kenya, Zipporah Njagu, Steve Mihok, Elizabeth Kokwaro, Didier Verloo

All Peer-Reviewed Publications

Monitor lizards were sampled along the shores of Lake Victoria to detect natural infections of potentially human-infective trypanosomes. In an area with endemic rhodesian sleeping sickness, one of 19 lizards was infected (Busia, Kenya). Six of ten lizards also showed indirect evidence of infection with Trypanosoma brucei (antibody ELISA). In an area with no recent history of human disease (Rusinga Island), no parasites were found and no antibodies to T. brucei were detected. The isolate was identified as T. brucei through xenodiagnosis (completion of the life cycle in the salivary glands of tsetse), and through molecular techniques (positive reactions with …

Corythalia Canosa (Araneae: Salticidae) Reassigned To Anasaitis, G. B. Edwards

Insecta Mundi

Four species of Corythalia C.L.Koch 1851 were reported by Richman & Cutler (1978) to occur in North America north of Mexico. Subsequently, one of these four species, C. delicatula Gertsch & Mulaik 1936, was synonymized with Euophrys diminuta (Banks 1896) (Edwards 1980). Of the three remaining species, only two species can validly be placed in the genus. These are C. conspecta (Peckham & Peckham 1896) and C. opirna (Peckham & Peckham 1885), the northernmost species in the genus, both with reported distributions ranging from Central America to Arizona.

The Occurrence Of The Genus Maruina (Diptera: Psychodidae) In Texas, David E. Bowles

Insecta Mundi

I recently collected immature stages of the aquatic dipteran genus Maruina from a spring-run located in the Big Bend region of western Texas. The spring-run, Ojito Adentro, is located in the Bofecillos Canyon Drainage, Presidio County, Texas at N29° 29'27.7", W 104° 3' 45.6" (measured with a Garmin GPS40 global positioning system). I collected specimens from the wetted vertical surface of a large boulder in the stream channel. A thin film of water flowed over this boulder creating a madicolous habitat. The habitat was thoroughly described in Sites and Bowles (1995) and Bowles et al. (1999). No adults were collected.
