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 …

Book Review: Brentidae Of The World (Coleoptera: Curculionoidea) (Sforzi, A., And L. Bartolozzi), Nico M. Franz

Insecta Mundi

This new book on the Brentidae of the World was originally conceived as an update of Richard Kleine’s (1938) checklist. It turned out to be much more. The checklist evolved into a comprehensive and meticulously annotated catalogue. A long introductory section was added, and enriched with clear illustrations and superb color photographs of charismatic specimens. It could stand on its own as a smaller book on the biology and taxonomic history of brentid beetles. The editors also enlisted a select group of experts to contribute four chapters on lineages recently placed within or close to the family. The result is …

Close-Range Host Searching Behavior Of The Stemborer Parasitoids Cotesia Sesamiae And Dentichasmias Busseolae: Influence Of A Non-Host Plant Melinis Minutiflora, Linnet S. Gohole, William A. Overholt, Zeyaur R. Khan, Louise E.M. Vet

All Peer-Reviewed Publications

Studies were conducted on the host searching behavior of the larval parasitoid Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) and the pupal parasitoid Dentichasmias busseolae Heinrich (Hymenoptera: Ichneumonidae), both of which attack lepidopteran (Crambidae, Noctuidae) cereal stemborers. The behavior of D. busseolae was observed in a diversified habitat that consisted of stemborer host plants (maize, Zea mays L. and sorghum, Sorghum bicolor (L). Moench (Poaceae)) and a non-host plant (molasses grass, Melinis minutiflora Beauv. (Poaceae)), while C. sesamiae was observed separately on host plants and molasses grass. In previous olfactometer studies, C. sesamiae was attracted to molasses grass volatiles while D. busseolae …
