A Taxonomic Review Of Chlosyne Ismeria With Description Of A New Subspecies From The Southern Appalachian Mountains, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The taxon Boisduval and Le Conte described in 1833 as Melitaea ismeria is examined as a historical entity and confirmed as a sister subspecies of the taxon Chlosyne ismeria nycteis. The ismeria populations in the southern Appalachian mountains (United States) are described as a new subspecies: Chlosyne ismeria obsoleta. In facies, this new subspecies is most similar to the western subspecies Chlosyne ismeria drusius in that it is dark and contrasting in its dorsal markings. It is known to range from the mountain region of extreme northern Georgia north in the Appalachians to near southwestern Virginia, United States. …

Convergent Habitat Segregation Of Aedes Aegypti And Aedes Albopictus (Diptera : Culicidae) In Southeastern Brazil And Florida, Marieta A H Braks, Ricardo Lourenco-De-Oliveira, Steven A. Juliano, Nildimar A. Honorio, L Philip Lounibos

Faculty Publications – Biological Sciences

During the rainy season of 2001, the incidence of the dengue vectors Aedes aegypti and Ae. albopictus was examined in different habitats of two cities (Rio de Janeiro and Nova Iguacu) in Rio de Janeiro State, Brazil, and in two cities (Palm Beach and Boca Raton) in Florida. Oviposition trap collections were performed in urban, suburban, and rural habitats in both areas. Our hypothesis that the abundances and frequencies of occurrence of Ae. aegypti and Ae albopictus are affected in opposite ways by increasing urbanization was only partially supported. City, habitat, and their interaction significantly affected the abundance of both …

Host Species, Age And Sex As Factors Affecting The Susceptibility Of The African Tephritid Fruit Fly Species, Ceratitis Capitata, C. Cosyra And C. Fasciventris To Infection By Metarhizium Anisopliae, S. Dimbi, N. K. Maniania, S. A. Lux, J. M. Mueke

All Peer-Reviewed Publications

The effect of host age and sex on the susceptibility of 3 tephritid fruit fly species, Ceratitis capitata (Wiedemann), C. cosyra (Walker) and C. fasciventris (Bezzi) to the entomopathogenic fungus Metarhizium anisopliae (Metchnikoff) Sorokin was studied in the laboratory. Three adult host ages, 0 (<1 day-old), 7-day-old and 14-day-old, were used. All 3 species were susceptible to fungal infection, although there were differences in the levels of susceptibility among the hosts. Age accounted for the largest variability in mortality followed by species, while sex had the lowest variability. Of the 3 host ages tested, the 0- and 7-day-old flies were more susceptible to fungal infection than the 14-day-old flies. Male and female C. fasciventris flies generally succumbed earlier to fungal infection than the other two species. Female flies of C. cosyra and C. fasciventris were also generally more susceptible to fungal infection than the males, although differences were apparent at 3 and 4 days after treatment but not 5 days after treatment. Age accounted for the largest variability in lethal time mortality values (LTs). Mean LT-values generally indicated that the speed of kill was faster among younger flies than the older flies. LT95 ranged between 3.9-4.9 days in the 0-day-old flies, 4.3-6.1 days in the 7-day-old flies and 4.6-6.1 days in 14-day-old flies in the different species and sexes. The implication of this study for the management of fruit flies is discussed.

Responses Of Glossina Morsitans Morsitans To Blends Of Electroantennographically Active Compounds In The Odors Of Its Preferred (Buffalo And Ox) And Nonpreferred (Waterbuck) Hosts, Nicholas K. Gikonyo, Ahmed Hassanali, Peter G.N. Njagi, Rajinder K. Saini

All Peer-Reviewed Publications

In a previous study, comparison of the behavior of teneral Glossina morsitans morsitans on waterbuck, Kobus defassa (a refractory host), and on two preferred hosts, buffalo, Syncerus caffer, and ox, Bos indicus, suggested the presence of allomones in the waterbuck odor. Examination of the volatile odors by coupled gas chromatography-electroantennographic detection showed that the antennal receptors of the flies detected constituents common to the three bovids (phenols and aldehydes), as well as a series of compounds specific to waterbuck, including C8 - C13 methyl ketones, δ-octalactone, and phenols. In this study, behavioral respones of teneral G. m. morsitans to different …

Research On The Genetics Of Screwworms In Lincoln, Nebraska, Steven Skoda, Dennis Berkebile, Margaret Allen

Department of Entomology: Faculty Publications

The success of the screwworm eradication program - these pests have been eliminated from the North American continent to Panama - has been facilitated by insightful research. The recent research on screwworms by ARS scientists at Lincoln, NE has concentrated on 1) discovering molecular markers useful in population genetics and population identification; 2) genetic research useful in developing a genetic sexing strain (males-only) in screwworms. Amplified fragment length polymorphisms (AFLP) have been studied in screwworms; this technique shows the potential for use in population identification and population genetics. AFLP's will be further explored to determine their utility: a grant proposal …

Parameter Estimation For Distributed Delay Based Population Models From Laboratory Data: Egg Hatching Of Oulema Duftschmidi Redthenbacher (Coleoptera, Chrysomelidae) As An Example, Maurizio Severini, Johann Baumgärtner, Lidia Limonta

All Peer-Reviewed Publications

The cohort development of poikilotherms under favorable temperature conditions may be described by the time-invariant distributed delay models that require three parameters, i.e. the thermal threshold T0, the thermal constant W and the variability parameter H representing distributed maturation times, also known as time distributed or stochastic development. Here, a parsimonious method is developed that uses stage-frequency matrices obtained under controlled conditions. The analysis of these matrices permits the estimation of the three parameters, while the incorporation of both developmental threshold and thermal constant into the time-invariant distributed delay model permits the representation of stochastic cohort development under constant temperatures. …

Book Review: Insecta Coleoptra Chironidae (Huchet, J.-B. 2003), Andrew B. T. Smith

University of Nebraska State Museum: Entomology Papers

The Fauna of Madagascar series has been around for almost 50 years. In that time authors have published on a variety of taxa that occur on this remarkable island. Throughout the history of the series there has been a heavy emphasis on beetles. The latest volume by Jean-Bernard Huchet is no exception. Huchet is an expert on Chironidae (or Chironinae depending on which scarab classification scheme you ascribe to). He is in the process of giving a much-needed taxonomic overhaul to the group. Chironidae are odd-looking scarabs that occur in Africa, Asia (mainly India), and Madagascar and are allied taxonomically …

Taxonomic Changes For Fifteen Species Of North American Mordellidae (Coleoptera), Anneke E. Lisberg

Insecta Mundi

In an attempt to more consistently apply generic concepts, 13 species of Mordellidae are transferred to different genera. Mordellistena bihamata (Melsheimer) and Mordellistena discolor (Melsheimer) are transferred to Falsomordellistena Ermisch, 1941, while 11 species (Mordellistena ancilla LeConte, Mordellistena floridensis Smith, Mordellistena guttulata Helmuth, Mordellistena impatiens LeConte, Mordellistena infima LeConte, Mordellistena lecontei Ermisch, Mordellistena minutalis Liljeblad, Mordellistena nigricans Melsheimer, Mordellistena parva Liljeblad, Mordellistena semiusta LeConte, and Mordellistena testacea Blatchley) are transferred to Mordellina Schilsky, 1908. Two species, Mordellistena rufa Liljeblad and Mordellina ustulata (LeConte), are proposed as junior synonyms of Mordellina ancilla (LeConte).

First Records Of Cyclolabus Carolinensis Heinrich In Florida (Hymenoptera: Ichneumoninae: Platylabini), Charles C. Porter

Insecta Mundi

Cyclolabus Heinrich may be recognized by the following combination of characters: clypeus convex in profile; propodeum with spiracle circular or nearly so and without projecting cristae; petiole dorsally flattened, wider than high; thyridia strongly trans- verse (each wider than the space between them).

This genus is mostly Holarctic in distribution with some overlap into the Oriental region and the northern Neotropics (Yu and Horstmann 1997). In the Nearctic it is known mainly from Canadian and Transition zone localities, except for C. carolinensis described by Heinrich (1962) from western South Carolina. Heinrich does not include Cyclolabus in his 1977 review of …

External Morphology Of The First And Second Instars Of Lecanodiaspis Tingtunensis (Coccoidea: Lecanodiaspididae), P. L. Lambdin, Elzbieta Podsiadlo

Insecta Mundi

The first and second instars of Lecanodiaspis tingtunensis are described and illustrated. First instars are distinguished from other species of Lecanodiaspis by the arrangement of dorsal 8-shaped pores in six complete longitudinal rows and a partial row in the thoracic region and the number of labial, anal plate, and spiracular setae. Second instars are dimorphic with males possessing well developed 5-segmented legs, dorsal tubular ducts, and long hair-like setae on the venter between the antennae and on the abdominal segments. Females have fewer 8-shaped pores in transverse rows on the dorsum, as well as legs reduced to stubs and only …

An Annotated Checklist Of Wisconsin Mordellidae (Coleoptera), Anneke E. Lisberg, Daniel K. Young

Insecta Mundi

A three-year survey of Wisconsin Mordellidae (Coleoptera) encompassing a compilation of data from literature records and local collections as well as field work including trapping, hand-collecting, and rearing yielded 68 species comprising 14 genera in three tribes. Sixty-three species (92% of Wisconsin fauna) represent new state species records, not previously recorded from the state in the literature. Plant-associations and state-specific temporal and spatial distribution data for larvae and adults are noted as available. Distributional records suggest 16 additional species and one additional genus are likely to occur in Wisconsin.

Ataeniopsis Edistoi (Cartwright) In Florida (Scarabaeidae: Aphodiinae), Paul E. Skelley

University of Nebraska State Museum: Entomology Papers

Ataenius edistoi Cartwright (1974) was described from a series of eight specimens collected near the Edisto River in South Carolina. All were "collected under surface litter on sandy but hard ground along the roadside". According to Cartwright (1974) attempts to collect the species at light at the type locality were not successful, indicating the species does not come to light. The species was transferred to the genus Ataeniopsis Petrovitz by Stebnicka (2003) in a revision of the genus. Ataeniopsis differs from Ataenius Harold in that the apical half of the pygidium in Ataeniopsis is smooth and glabrous, while in Ataenius …
