Investigation Into The Population Dynamics And Key Life History Characteristics Of Non-Biting Midge (Diptera: Chironomidae) Which Can Be Utilised To Improve Nuisance Control At Lake Joondalup, Western Australia, Michael Roberts

Theses : Honours

Non-biting midges (Diptera: Chironomidae) become a severe nuisance to humans living close to urban wetlands when they emerge at night to form mating swarms. The phototactic nature of adult chironomids means that large quantities of chironomids congregate around artificial lighting prominent in the surrounding suburbs of urban wetlands. This nuisance problem has compelled the investigation of suitable control options which are able to reduce the numbers of midges to below nuisance levels for an extended period. Currently the options available to control chironomid populations rely on the treatment of affected wetlands with pesticide. These treatment regimes are usually only successful …

Integrated Arthropod Pest Management Systems For Human Health Improvement In Africa, Johann Baumgärtner, Fritz Schulthess, Yunlong Xia

All Peer-Reviewed Publications

In a sub-Saharan African context, limited natural resources, infectious diseases, including those transmitted by arthropod vectors, and chronic exposure to food contaminated with mycotoxin-producing fungi which, among others, are vectored by insects, are among the major constraints to human health. Thus, pest control should be an important component in human health improvement projects. It appears that the advantages of preventive over curative methods are rarely recognised in Africa, with more emphasis being given to the search for the 'silver bullet' than to integrated control approaches. Integrated pest management (IPM) systems can be assigned to different decision-making levels as well as …

Ring A-Seco Mosquito Larvicidal Limonoids From Turraea Wakefieldii, Mary Ndung'u, Ahmed Hassanali, Antony M. Hooper, Sumesh Chhabra, Thomas A. Miller, Rowena L. Paul, Baldwyn Torto

All Peer-Reviewed Publications

Five novel limonoids, 1-5, were isolated from the root bark of Turraea wakefieldii and were characterized as tecleaninoid derivatives. This is the first report of the natural occurrence of tecleanin-type limonoids with a five-membered-ring A-seco structure for which we propose the name neotecleanins. The relative stereochemical structures of compounds 1-5 were established on the basis of NMR spectroscopy. The absolute stereochemical structure of 5 was confirmed by X-ray diffraction methods. In mosquito larvicidal assays, compounds 1, 2 and 4 showed dose-dependent larvicidal activity against larvae of Anopheles gambiae s.s. © 2003 Elsevier Ltd. All rights reserved.

Olfactory Responses Of Cotesia Flavipes (Hymenoptera: Braconidae) To Target And Non-Target Lepidoptera And Their Host Plants, Bekele Jembere, Adele J. Ngi-Song, W. Overholt

All Peer-Reviewed Publications

The attraction of Cotesia flavipes Cameron to volatiles from a range of non-target lepidopteran larvae and their host plants (grasses and trees) or food substrate (honeycomb) was evaluated using a Y-tube olfactometer. The non-target host larvae used in the study included Galleria mellonella (L.), Charaxes cithaeron Felder, Bombyx mori L., and Eldana saccharina Walker. The target insects, Chilo partellus (Swinhoe) and Chilo orichalcociliellus (Strand), were used as controls. Host plants included Afzelia quanzensis Welw., Morus alba L., Cyperus papyrus L., Pennisetum purpureum Schumach, and Zea mays L. The response of C. flavipes to volatiles from the non-target larvae and their …

Nzovu, Weidong Gu, Guiyan Yan, James T. Gunter, Chris Swalm, Joseph Keating, James L. Regens, Josephat I. Shililu, John I. Githure, John C. Beier

All Peer-Reviewed Publications

The seasonal dynamics and spatial distributions of Anopheles mosquitoes and Plasmodium falciparum parasites were studied for one year at 30 villages in Malindi, Kilifi, and Kwale Districts along the coast of Kenya. Anopheline mosquitoes were sampled inside houses at each site once every two months and malaria parasite prevalence in local school children was determined at the end of the entomologic survey. A total of 5,476 Anopheles gambiae s.l. and 3,461 An. funestus were collected. Species in the An. gambiae complex, identified by a polymerase chain reaction, included 81.9% An. gambiae s.s., 12.8% An. arabiensis, and 5.3% An. merus. Anopheles …

Inhibitory Properties Of Microplitis Croceipes Teratocyte Secretory Products And The Recombinant Protein Tsp14 On Protein Synthesis, Francis Anthony Diluna

University of Kentucky Master's Theses

Microplitis croceipes is a solitary endoparasitic wasp that oviposits in the hemocoel of Heleothis virescens larvae. Upon parasitization, the host larvaes physiology is altered; resulting in a compromised immune system and a decrease in the production of some vital proteins resulting in a terminal post-wandering prepupal state. Teratocytes, cells derived from the extraembryonic serosa of the parasitic wasp, mimic symptoms of parasitization when injected into host larvae, independent of other factors like polydnavirus and venom. Some of the inhibition of protein synthesis can be attributed to proteins secreted by the teratocytes (teratocyte secretory proteins or TSP). A fraction of TSP …

Malariasphere: A Greenhouse-Enclosed Simulation Of A Natural Anophelesgambiae (Diptera: Culicidae) Ecosystem In Western Kenya, Bart G.J. Knols, Basilio N. Njiru, Evan M. Mathenge, Wolfgang R. Mukabana, John C. Beier, Gerry F. Killeen

All Peer-Reviewed Publications

Background: The development and implementation of innovative vector control strategies for malaria control in Africa requires in-depth ecological studies in contained semi-field environments. This particularly applies to the development and release of genetically-engineered vectors that are refractory to Plasmodium infection. Here we describe a modified greenhouse, designed to simulate a natural Anopheles gambiae Giles ecosystem, and the first successful trials to complete the life-cycle of this mosquito vector therein. Methods: We constructed a local house, planted crops and created breeding sites to simulate the natural ecosystem of this vector in a screen-walled greenhouse, exposed to ambient climate conditions, in western …

The Taxonomic Report of the International Lepidoptera Survey

A study was conducted in six different localities around Skardu, Pakistan to document the butterfly fauna of that region. The study revealed that 16 species in 5 families and 14 genera occur in the area. The families include: Papilionidae (represented only by the genus Parnassius); Pieridae (genera Pieris, Pontia, and Colias are represented); Lycaenidae (genera Lycaena, Everes, Aricia, Plebejus, Zizeeria, and Zizina are represented); Nymphalidae (only two genera, Aglais and Cynthia are represented); and Satyridae (represented by the genera Pararge and Maniola).

Bolboceras Kirby, 1819 (July) (Insecta, Coleoptera): Proposed Precedence Over Odonteus Samouelle, 1819 (June), Mary Liz Jameson, H. F. Howden

University of Nebraska State Museum: Entomology Papers

The purpose of this application, under Articles 23.9.3 and 8 1.2.3 of the Code, is to conserve the generic name Bolboceras Kirby, 1819 for a group of scarab beetles (family GEOTRUPIDAE) by giving it conditional precedence over the older name Odonteus Samouelle, 18 19 whenever they are considered to be synonyms. The name Bolboceras is threatened by a single usage by Krelljn 1990 of the otherwise unused name Odonteus.

Three species of bostrichid beetles, previously unknown from Florida, were found in the Florida State Collection of Arthropods (FSCA) and in the Archbold Biological Station Collection. The genus Stephanopachys Waterhouse, in Florida, is now represented by four species. These new records probably represent infrequently collected species and not new introductions to Florida. A key to all species of Stephanopachys adults from Florida is presented.

Mexican Lepidoptera Biodiversity, J. B. Heppner

Insecta Mundi

Being among the most habitat diverse countries in the world (and plant diversity is about 22,000 sp.), Mexico has a Lepidoptera fauna recorded at about 14,385 species but is estimated to be over 22,000 species, if not much higher (some estimates go to 35,000 sp.). High Lepidoptera numbers in Mexico are also due to the large influx of tropical species from the border with Guatemala, as well as Mexican endemics. In this report, the Lepidoptera families are summarized for Mexico, giving known species and what experts estimate to be the true total for each family when all have been described. …

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

Insecta Mundi

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. Nonetheless, the list cited in Forrester and Spalding (2003) contains few and spotty county records. The main source of material for this publication has been the Marathon Wildlife Rehabilitation Center in Marathon, Monroe Co., Florida. The center takes in specimens of about 90 species of birds per year. The following is a list of the avian lice species, hosts, and localities with collection dates. All …

Inbreeding, Male Diploidy, And Complementary Sex Determination In The Solitary Wasp Euodynerus Foraminatus, Julie Kozaczka Stahlhut

Dissertations

In the insect order Hymenoptera, which includes wasps, bees, and ants, females normally develop from fertilized eggs and are diploid, while males develop from unfertilized eggs and are haploid. Underlying mechanisms of sex determination are more complex and vary among different hymenopteran taxa. One such method is single-locus complementary sex determination, or sl-CSD, in which sex is determined by a single gene locus with many alleles. In species with sl-CSD, diploid individuals that are heterozygous at the sex locus develop as normal females and hemizygous (haploid) individuals as normal males, but diploids homozygous at the sex locus will also develop …

Resistance Of Bt Transgenic Maize To Lesser Cornstalk Borer (Lepidoptera: Pyralidae), Francys M. F. Vilella, Jose M. Waquil, Evaldo F. Vilella, Paulo A. Viana, Paul E. Lynch, John E. Foster

Department of Entomology: Faculty Publications

The lesser cornstalk borer, Elasmopalpus lignosellus (Zeller) (Lepidoptera: Pyralidae), maize causes the symptom known as “dead heart” to maize. The objective of this research was to evaluate if Bt maize would protect seedlings against lesser cornstalk borer damage and whether different temperatures affect the insect-plant interaction.

Two experiments were conducted. Seeds from Pioneer Bt maize hybrids P33G27, P34R07, P34G82, P33A14, and P34D34, expressing the toxin Cry1A(b) were obtained from the market. Seeds from the hybrids Mycogen (experimental) and Garst 8539 expressing, respectively, the toxin Cry1F and Cry9C as well as the control Garst 8539 (non-Bt) were obtained from the seed …

Diagnostic Assays Based On Esterase-Mediated Resistance Mechanisms In Western Corn Rootworms (Coleoptera: Chrysomelidae), Xuguo Zhou, Michael E. Scharf, Srinivas Parimi, Lance J. Meinke, Robert J. Wright, Laurence D. Chandler, Blair D. Siegfried

Department of Entomology: Faculty Publications

Resistance to methyl-parathion among Nebraska western corn rootworm, Diabrotica virgifera virgifera LeConte, populations is associated with increased hydrolytic metabolism of an organophosphate insecticide substrate. An electrophoretic method to identify resistant individuals based on the staining intensity of esterase isozymes on nondenaturing polyacrylamide gels was developed. Three groups of esterases (I, II, and III) were visible on the gels, but only group II esterase isozymes were intensified in resistant populations. A total of 26 and 31 field populations of western corn rootworms from Nebraska (in 1998 and 1999, respectively) were assessed with nondenaturing polyacrylamide gel electrophoresis (PAGE) assays and diagnostic concentration …

New World Screwworm Synthetic Sex Stimulant, David A. Carlson, Dennis Berkebile, Steven R. Skoda, Kenji Mori

Department of Entomology: Faculty Publications

The presence of a sex pheromone in (New World Screwworm) females was demonstrated some time ago, but no natural compounds were isolated for proof of activity, and no synthetic compounds were ever tested. We report biological activity as powerful aphrodisiacs for synthetics in declining order of compounds 1, 4, 3, 2 and 5. Two types of bioassays were conducted to compare the stimulatory activity of these compounds against mature virgin males. Four compounds were the acetates of secondary alcohols with 29 carbon backbones, each with a variably-positioned methyl branch near the opposite end of the chain and one was a …
