Environmental Hypoxia Influences Hemoglobin Subunit Composition In The Branchiopod Crustacean Triops Longicaudatus, J. A. Guadagnoli, A. M. Braun, S. (Stephen) P. Roberts, C. L. Reiber

Biological Sciences Faculty Research & Creative Works

Hemoglobin (Hb) is a Highly Conserved Protein that Provides a Vital Link between Environmental Oxygen and its Use And/or Storage within an Organism. While Ubiquitous among Vertebrates, Hb Occurs Frequently in Invertebrate Phyla as Well. Many Arthropod Species Use the Copper-Binding Pigment Hemocyanin, But Unique in This Phylum Are the Branchiopod Crustaceans, Which Express Hb. Branchiopod Hb Concentration and Structure Are Exquisitely Sensitive to Environmental Oxygen Availability. Hemoglobin Concentration and Oxygen-Binding Affinity Increase with Decreasing Oxygen Tension in Daphnia, Artemia and Triops. the Change in Binding Affinity is Attributed to Differential Hb Subunit Expression in Daphnia and Artemia But Remains …

First Report Of Diaphorina Citri (Hemiptera: Psyllidae) In Costa Rica, William Villalobos, David Hollis, Carolina Godoy, Carmen Rivera

Insecta Mundi

The Asian citrus psyllid (Diaphorina citri Kuwayama (Psyllidae)) and the African citrus psyllid (Trioza erytreae (Del Guercio) (Triozidae)) are two of the most serious pests of citrus in the world (Hoy and Nguyen 1998). The Asian citrus psyllid is usually found crowded on the lower sides of leaves, with the head almost touching the surface and the body raised almost to a 30 degree angle. The greatest activity of this psyllid occurs simultaneous with new citrus growth (Frank 1998). The Asian psyllid causes leaf distortion and curling in young tender growth due to direct feeding damage and toxic …

The First Record Of Phidippus Bidentatus (Araneae: Salticidae) In The United States, G. B. Edwards

Insecta Mundi

University of Florida, Gainesville, FL A male of a neotropical jumping spider, Phidippus bidentatus F. O. P.-Cambridge 1901, was collected by John Scott Armstrong and his staff from a boll weevil trap in Cameron County, Texas. The recent revision of the genus Phidippus (Edwards 2004) gave the range of this species as central Mexico to northwest Costa Rica. In addition, the specimen has a character, namely the presence of a distinct cheliceral distal dorsal tubercle, that would make it key out in the second couplet of the key, along with Phidippus audax (Hentz) and P. regius C. L. Koch. However …

New Host Records Of Chewing Lice (Mallophaga) On Birds In Florida Iii, J. Adam Holt

Insecta Mundi

Here, I report some new county and Florida host records as well as two new U.S. host records for avian lice. County records for avian lice are less significant than the host records themselves. Considering that most avian lice are host specific, the county records should resemble the area the host would most likely be encountered. The main source of material for this publication has been the Marathon Wildlife Rehabilitation Center in Marathon, Monroe County, Florida, with Kelly Grinter as the official curator and keeper. The center takes in about 90 different species of birds per year. The following is …

A Distributional Checklist Of The Leaf-Cutting Bees (Hymenoptera: Megachilidae) Of Florida, J. M. Leavengood Jr., D. Serrano

Insecta Mundi

The leaf-cutting bees are a diverse group which is commonly encountered all across the country. With over 600 North American species, most of which are in the genera Anthidium, Dianthidium, Stelis, Heriades, Hoplitis, Osmia, Megachile and Coelioxys, there are numerous “non-Apis” pollinators. Being an important taxon, there is a definite need for an awareness of their distribution across the United States and, perhaps in time, everywhere. This may allow us to follow the establishment of exotic species such as Megachile [Callomegachile] torrida Smith, M. [Pseudomegachile] lanata Fabricius, and an unidentified exotic which is listed below in the subgenus Callomegachile …

Curius Punctatus (Fisher), New Combination (Coleoptera: Cerambycidae: Cerambycinae: Curiini), Eugino H. Nearns, Marc A. Branham

Insecta Mundi

Fisher (1932) described Pentomacrus punctatus from eight specimens, the holotype of which is a male specimen deposited in the USNM, type locality Santiago de las Vegas, Cuba (Fig. 1b). Giesbert (1985) synonymized Pentomacrus with Plectromerus. Plectromerus punctatus (Fisher) is listed as endemic to Cuba (Fisher 1932, Monné 2005, Monné and Hovore 2003, Peck 2005).

First Record Of Plectromerus Exis Zayas In The Dominican Republic (Coleoptera: Cerambycidae), Eugenio H. Nearns, Robert H. Turnbow Jr.

Insecta Mundi

During revisionary work on the tribe Curiini LeConte, 1873, a new country record for Plectromerus exis Zayas was noticed. Plectromerus exis was described by Fernando de Zayas in 1975 from five specimens collected in several localities in Cuba (Zayas, 1975) and is listed as endemic to that island (Monné, 2005; Monné and Hovore, 2005; Peck, 2005). The senior author recently studied the holotype and type series of P. exis deposited in the Zayas Collection, La Habana, Cuba (Nearns, 2005).

Termite (Isoptera) Diversity In Senegal And Their Damage On Reforestation Areas And Cultures, Makhfousse Sarr, Nguya K. Maniania, A. Russell-Smith, Abdoulaye Niassy

All Peer-Reviewed Publications

Studies conducted from 1969 to 2000 on termite ecology and biology in Senegal revealed high termite diversity and an influence of climate and soil conditions on termite group distribution. Sixty-four termite species were recorded. Some were specific to ecologically similar zones while others were widely distributed. Some species, known to inhabit wet zones, were found in semi-arid zones where relic forest vegetation still exists. Nioro, in the central part of the country, seems to be the buffer zone between species to the north and south of Senegal. In Ferlo, an arid zone, Macrotermes species was in regression and the subsisting …

Repellency Of Essential Oils Of Some Plants From The Kenyan Coast Against Anopheles Gambiae, Josiah O. Odalo, Maurice O. Omolo, Hamisi Malebo, John Angira, Patrick M. Njeru, Isaiah O. Ndiege, Ahmed Hassanali

All Peer-Reviewed Publications

Volatile oils extracted by hydrodistillation from six plant species growing in the Kenyan coast, Croton pseudopulchellus Pax, Mkilua fragrans Verdc. (Annonaceae), Endostemon tereticaulis (poir.) Ashby, Ocimum forskolei Benth., Ocimum fischeri Guerke and Plectranthus longipes Baker (Labiateae), were evaluated for repellency on forearms of human volunteers against Anopheles gambiae sensu stricto. All oils were found to be more repellent (RC50 range = 0.67-9.21 × 10-5 mg cm-2) than DEET (RC50 = 33 × 10-5 mg cm-2). The individual components of the oils were identified by GC-MS and GC co-injections with authentic standards. The repellency of 15 of the main constituents of …

The Effect Of Host Larvae On Three Psyttalia Species (Hymenoptera: Braconidae), Parasitoids Of Fruit-Infesting Flies (Diptera: Tephritidae), M. K. Billah, S. Kimani-Njogu, W. A. Overholt, R. A. Wharton, D. D. Wilson, M. A. Cobblah

All Peer-Reviewed Publications

Three species of fruit fly parasitoids, Psyttalia concolor (Szépligeti), Psyttalia cosyrae (Wilkinson) and Psyttalia lounsburyi (Silvestri) (Hymenoptera: Braconidae) were reared on different host larvae to determine the effects of host species, size and colour on parasitoid development. Ovipositor, ovipositor sheath and hind tibia lengths were found to be different for progenies from preferred and non-preferred host larvae. Ratios of ovipositor-tibia and ovipositor sheath-tibia showed no difference when P. concolor was reared on a bigger host (Ceratitis cosyra (Walker) (Diptera: Tephritidae), whereas rearing P. cosyrae on a smaller host (C. capitata (Wiedemann) showed significant differences. Comparison of the linear measurements, ratios …

Comparative Genetic Studies Of Native And Introduced Coccinellidae In North America, Elliot S. Krafsur, John J. Obrycki, James D. Harwood

Entomology Faculty Publications

During the past four decades, several species of aphidophagous Coccinellidae became established in North America, including Coccinella septempunctata, Harmonia axyridis, Hippodamia variegata, and Propylea quatuordecimpunctata. After their establishment, unknown circumstances favoured a rapid increase in population densities and distribution of H. axyridis and C. septempunctata at localities hundreds and thousands of kilometers from their release sites. Propylea quatuordecimpunctata and Hippodamia variegata have spread more slowly after becoming established in northeastern North America. Comparative studies based upon allozyme variation in these four introduced species and in six native North American species of ladybird beetles revealed …

Quantifying Aphid Predation Rates Of Generalist Predators In The Field, James D. Harwood, John J. Obrycki

Entomology Faculty Publications

The community of predators within agroecosystems has the potential to restrict aphid populations, especially early in the season before exponential increases in density and prior to the arrival of specialist natural enemies. Although direct observations of predation, laboratory feeding trials and manipulative field studies have been used to estimate levels of biological control exerted by different species (or potentially negative interactions between them), it is often difficult to extrapolate results to naturally occurring interactions in the field.

Over 100 investigations have utilized gut-content analysis to estimate aphid predation rates by predators. Throughout the last century, gut dissection, which enables the …

Baseline Susceptibility Of Western Corn Rootworm (Coleoptera: Crysomelidae) To Cry3bb1 Bacillus Thuringiensis Toxin, Blair D. Siegfried, Ty T. Vaughn, Terrence A. Spencer

Department of Entomology: Faculty Publications

Susceptibility to Cry3Bb1 toxin from Bacillus thuringiensis (Bt) was determined for western corn rootworm, Diabrotica virgifera virgifera LeConte, neonates from both laboratory and field populations collected from across the Corn Belt. Rootworm larvae were exposed to artificial diet treated with increasing Cry3Bb1 concentrations, and mortality and growth inhibition were evaluated after 4Ð7 d. The range of variation in Bt susceptibility indicated by growth inhibition was similar to that indicated by mortality. Although interpopulation variation in susceptibility was observed, the magnitude of the differences was comparable with the variability observed between generations of the same population. In general, the toxin was …

Flight Behavior Of Methyl-Parathion-Resistant And –Susceptible Western Corn Rootworm (Coleoptera: Chrysomelidae) Populations From Nebraska, Jenny A. Stebbing, Lance J. Meinke, Steve E. Naranjo, Blair Siegfried, Robert J. Wright, Laurence D. Chandler

Department of Entomology: Faculty Publications

Relative flight behavior of methyl-parathion-resistant and -susceptible western corn rootworm, Diabrotica virgifera virgifera LeConte populations, was studied as part of a larger effort to characterize the potential impact of insecticide resistance on adult life history traits and to understand the evolution and spread of resistance. A computer interfaced autograph was used to compare flight of resistant and susceptible individuals, and flight of resistant individuals with and without prior exposure to methyl-parathion. In each case, mean trivial and sustained flight durations were compared among treatments. In general, there were few differences in trivial or sustained flight characteristics as affected by beetle …

Taxonomic Analysis Of The Genus Megisto (Satyridae) In The Eastern United States, Part I: Types, Type Localities, And Taxonomic Relationships Of The Available Names, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

The genus Megisto Hübner, 1819 in the eastern United States and southeastern Canada is currently comprised of the original epithets Papilio eurytus Fabricius, 1775, Papilio cymela Cramer, 1777, Papilio eurytris, Fabricius, 1793, and Neonympha eurytris viola Maynard, 1891. Because the eastern Megisto is considered by some, including the present author, to contain two or more sibling species, the types and type localities of each of these names were studied. Where no type was found and no type locality fixed, typification was established by lectotypification or neotypification and a type locality was fixed. The taxonomic relationship of these taxa were …
