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. …

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 …

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.

Plasticity In Selective Phonotaxis And Neuronal Responses Of Acheta Domesticus, Benjamin Alejandro Navia

Loma Linda University Electronic Theses, Dissertations & Projects

Plasticity of phonotaxis in Acheta domesticus was evaluated in 207 young (5-7 days) and 328 old (28 days) female crickets. Of those that responded (508), their phonotaxis was grouped into selective (80% of young and 34% of old) and unselective (66% of old and 20% of young) on the basis of their responses to syllable period (SP). Two additional subcategories were also found. Some females were selective to the longer syllable periods (18% young, 20% old) while others were selective to the shorter syllable periods (7% young and 12% old). The L3 prothoracic auditory interneuron exhibits a decrementing response to …

Interactions Among Western Corn Rootworm (Coleoptera: Chrysomelidae), Yellow Foxtail, And Corn, M. M. Ellsbury, K. R. Banken, S. A. Clay, F. Forcella

Agronomy, Horticulture and Plant Science Faculty Publications

Field studies at sites with two contrasting soil types investigated effects from the presence of yellow foxtail [Setaria pumila (Poir.) Roem. and Schult.], established in bands parallel to corn rows, on western corn rootworm (Diabrotica virgifera virgifera LeConte) survival, corn root injury, lodging, biomass production, and yield. Results suggested that the presence of foxtail as an alternate host inßuenced the degree and progression of corn rootworm damage and adult emergence in a givenlocality. Rootworm adults emergedlater from foxtail band areas and had smaller head capsule size than did individuals from areas without foxtail, consistent with earlier Þndings that foxtail in …

Life Tables, Key Factor Analysis And Density Relations Of Natural Populations Of The Spotted Maize Stemborer, Chilo Partellus (Lepidoptera: Crambidae), Under Different Cropping Systems At The Kenyan Coast, C. A.O. Midega, C. K.P.O. Ogol, W. A. Overholt

All Peer-Reviewed Publications

Studies were conducted at Mtwapa, in the coastal area of Kenya, during the long and short rains of 1999 and 2000 to evaluate interaction of mortality factors in lowering Chilo partellus (Swinhoe) populations in diverse agroecosystems. Treatments consisted of hedgerows of leucaena only, gliricidia only, alternating rows of leucaena and gliricidia, and three plots without trees. During the cropping seasons, maize was planted between the hedgerows while a row of cowpea was planted between the rows of maize. One of the plots without trees was planted to an intercrop of maize and cowpea. The remaining two plots without trees were …

Rhabditis (Oscheius) Colombiana N. Sp. (Nematoda: Rhabditidae), A Necromenic Associate Of The Subterranean Burrower Bug Cyrtomenus Bergi (Hemiptera: Cydnidae) From The Cauca Valley, Colombia, S. Patricia Stock, Ana M. Caicedo, Paul A. Calatayud

All Peer-Reviewed Publications

Rhabditis (Oscheius) colombiana n. sp. is described as a necromenic associate of the burrower bug Cyrtomenus bergi (Hemiptera: Cydnidae) collected in the Cauca Valley, Colombia. The new species resembles others of the insectivora-group, viz, Rhabditis (O.) insectivora Körner, 1954 and Rhabditis (O.) lucianii Maupas, 1919, in a number of morphological and life history traits, but can be separated by a combination of morphological and morphometric characters. The most distinctive morphological features that separate R. (O.) colombiana n. sp. from these two Rhabditis species are the total size of both males and females, which are much shorter and slimmer in the …

Natural Loggers: Leaf Cutter Ants As Pests In Northwestern Ecuador, Aaron Honig

Independent Study Project (ISP) Collection

The biological world is under attack. All across the world in every continent and sub-continent biological diversity is rapidly decreasing (Wilson, 1999). As the human population continues to exponentially increase, especially in Third World countries where biological diversity reaches its peak, countless diverse biological habitats are threatened by accelerating human consumption and the growing needs of growing human populations. In Ecuador, only 1% of the original tropical forest remains, as a result of the accelerating need of viable agricultural tracts for Ecuador’s relatively poor farmers, as well as the unsustainable harvest of valuable hardwood tree species endemic to Ecuador’s primary …

Fumigant Toxicity Of The Essential Oils Of Some African Plants Against Anopheles Gambiae Sensu Stricto, M. O. Omolo, D. Okinyo, I. O. Ndiege, W. Lwande, A. Hassanali

All Peer-Reviewed Publications

The essential oils from 15 species of African plants selected by ethnobotanical considerations and field inspection (odour and presence of insects) were screened for fumigant toxicity to Anopheles gambiae s.s. in the laboratory. Essential oils from 6 species showed varying levels of toxicity, with Conyza newii (Compositae) and Plectranthus marruboides (Labiateae) being the most potent. Fifty compounds representing ∼74% of the essential oil of C. newii were identified by GC-MS and GC-coinjection (for available standards). The major and some of the minor constituents of the two oils were assayed at different doses. Two compounds, from C. newii, perillaldehyde and perillyl …

Collagenus Dasysternus, A New Genus And Species Of Dynastinae From Eastern Venezuela With A Key To The New World Genera Of Pentodontini (Coleoptera: Scarabaeidae: Dynastinae), Brett C. Ratcliffe, Martin Hardy

University of Nebraska State Museum: Entomology Papers

Collagenus dasysternus Ratcliffe and Hardy, new genus and species, is described from eastern Venezuela. We include a revised key to the 26 genera of New World Pentodontini. When the second author (Hardy) first saw this Venezuelan specimen in the Henry Howden collection, he could not readily place it to genus. When the first author (Ratcliffe) received the specimen from Hardy for examination in mid-2003, he was immediately taken with its gestalt similarity with the genus Coscinocephalus Prell that occurs in Arizona and Mexico. Unfortunately, there is only one specimen, but our examination revealed such unique character states that were indicative …

New Distribution Records For Two Species Of Cryptolestes Ganglbauer (Coleoptera: Laemophloeidae), Michael C. Thomas

Insecta Mundi

Suction traps being used to monitor aphid populations in Florida have produced specimens of two exotic species of Cryptolestes, suggesting both species are newly established in the “wild” in the United States. Examination of other collections has produced other new country records for one of the species. Specimens representing the Florida records are in the Florida State Collection of Arthropods; other specimens are in the collection of Rudolf Schuh, Vienna, Austria.

New Distribution Records For Arthrolips Fasciata (Erichson) (Coleoptera: Corylophidae), Michael C. Thomas

Insecta Mundi

While curating the Corylophidae in the Florida State Collection of Arthropods (FSCA) I came across a pair of strikingly marked Arthrolips from the Florida Panhandle. Shortly thereafter, I found another pair of apparently identical beetles from Taiwan. Examination of the spermathecae sup ported the conclusion that the two series represented the same species. Based on the illustrations of the spermatheca and habitus supplied by Bowestead (2003), both series are A. fasciata (Erichson). This species was described from Tasmania and has been recorded also from New South Wales and New Zealand, and recently (Bowestead 2003), as an immigrant, from France. Bowestead …
