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 …

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).

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 …

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 …

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 …

Asymmetrical Competition And Patterns Of Abundance Of Aedes Albopictus And Culex Pipiens (Diptera : Culicidae), Katie S. Costanzo, Kimberly Mormann, Steven A. Juliano

Faculty Publications – Biological Sciences

We tested for competitive advantage among larvae of Aedes albopictus (Skuse) and Culex pipiens L. in a laboratory experiment and determined the frequency and spatial and temporal patterns of co-occurrence in the field in East St. Louis, IL. In a laboratory competition experiment at multiple combined densities of Ae. albopictus and Cx. pipiens larvae, Ae. albopictus survivorship, and developmental times were significantly affected by conspecific densities but not by Cx. pipiens densities. In contrast, Cx. pipiens survivorship, and developmental times were significantly affected by both conspecific and Ae. albopictus densities. Per capita rate of increase (r') for Ae. albopictus cohorts …

Time And Frequency Of Applications Of Entomopathogenic Nematodes And Their Persistence For Control Of Western Flower Thrips Frankliniella Occidentalis, Difabachew Belay, Lemma Ebssa, Christian Borgemeister

All Peer-Reviewed Publications

Post application persistence of two entomopathogenic nematode (EPN) species, Heterorhabditis bacteriophora strain HK3 and Steinernema carpocapsae strain DD136, was studied against soil-dwelling late second instar larvae (L2) of western flower thrips (WFT) Frankliniella occidentalis (Thysanoptera: Thripidae). The nematodes were applied at 200 and 400 infective juveniles (IJ) cm-2, and L2 WFT were introduced at 0 (same day), 3, 6, 9 or 12 days after nematode application (DANA). Heterorhabditis bacteriophora caused higher thrips mortality than S. carpocapsae in most of the tests and both species persisted for at least 6 days, causing WFT mortality of up to 76 and 37.8%, respectively. …

Generalism Versus Specialism: Responses Of Diadegma Mollipla (Holmgren) And Diadegma Semiclausum (Hellen), To The Host Shift Of The Diamondback Moth (Plutella Xylostella L.) To Peas, A. Roßbach, B. Löhr, S. Vidal

All Peer-Reviewed Publications

A population of the diamondback moth Plutella xylostella (L.) (Lepidoptera: Plutellidae) (DBM) was recently found to infest sugar snap- and snowpeas in the Rift Valley in Kenya, causing heavy damage. The influence of this host shift on host location preferences of two parasitoids was investigated: The indigenous Diadegma mollipla (Holmgren) regarded as a relative generalist, and Diadegma semiclausum(Hellen), regarded as highly specific to DBM. The attractiveness of different odour sources was compared for the two parasitoid species using a Y-tube olfactometer using naïve females. D. mollipla was not significantly attracted to any cabbage related odours but showed a significant preference …

Biology, Habitat Preference, And Larval Description Of Cicindela Cursitans Leconte (Coleoptera: Carabidae: Cicindelinae), Mathew L. Brust, W. Wyatt Hoback, C. Barry Knisley

Department of Entomology: Faculty Publications

Cicindela cursitans LeConte is a small, flightless tiger beetle with a widely scattered distribution in the Great Plains, the Ohio Valley, and the north-central Gulf Coast region. Many aspects of the life history of C. cursitans are poorly known, and the larval stages have remained undescribed until now. We designed experiments to determine specific habitat preference, female oviposition preference, and daily activity cycles of the adults. In addition, we describe the entire pre-adult life history. Adults are most numerous on moist clay soils with sparse to patchy vegetation, but they may also occur in tall-grass prairies. Females oviposit strictly in …

Effects Of Grain Legumes And Cover Crops On Maize Yield And Plant Damage By Busseola Fusca (Fuller) (Lepidoptera: Noctuidae) In The Humid Forest Of Southern Cameroon, A. Chabi-Olaye, C. Nolte, F. Schulthess, C. Borgemeister

All Peer-Reviewed Publications

Field trials were run in the humid forest zone of Cameroon to investigate the effects of crop rotation, cover crops and bush fallow on infestations by the noctuid stemborer Busseola fusca (Fuller) and on yield of maize. A continuous maize production system was compared with crop sequence systems, in which maize followed a grain legume (cowpea, soybean), cover crop (mucuna, pigeon pea) or a bush fallow. Compared to the continuous maize cropping system, maize in the crop sequence with legume and fallow systems had significantly higher leaf and stem nitrogen content at 35 and 63 days after planting (DAP), respectively. …

Effects Of Flight Behaviour On Body Temperature And Kinematics During Inter-Male Mate Competition In The Solitary Desert Bee Centris Pallida, Stephen P. Roberts

Biological Sciences Faculty Research & Creative Works

Body Temperatures and Kinematics Are Measured for Male Centris Pallida Bees Engaged in a Variety of Flight Behaviors (Hovering, Patrolling, Pursuit) at a Nest Aggregation Site in the Sonoran Desert. the Aim of the Study is to Test for Evidence of Thermoregulatory Variation in Convective Heat Loss and Metabolic Heat Production and to Assess the Mechanisms of Acceleration and Forward Flight in Field Conditions. Patrolling Males Have Slightly (1-3°C) Cooler Body Temperatures Than Hoverers, Despite Similar Wingbeat Frequencies and Larger Body Masses, suggesting that Convective Heat Loss is Likely to Be Greater during Patrolling Flight Than during Hovering. Comparisons of …

Case 3314: Stegopterus Burmeister & Schaum, 1840 And Trichiotinus Casey, 1915 (Insecta, Coleoptera, Scarabaeidae): Proposed Conservation, Andrew Smith

University of Nebraska State Museum: Entomology Papers

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the names of two well-established genera of cetoniine scarab beetles, Stegopterus Burmeister & Schaum, 1840 and Trichiotinus Casey, 1915. Stegopterus Burmeister & Schaum is a junior synonym of Tetrophthalmus Kirby, 1827 and Trichiotinus Casey a junior synonym of Trichinus Kirby, 1827. The two junior names are in prevailing use and it is proposed that they be conserved by suppression of both Kirby's names.
