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.

Distribution And Biological Notes For Some Cerambycidae (Coleoptera) Occurring In The Southeastern United States, Roy F. Morris Ii

Insecta Mundi

The beetle family Cerambycidae is a favorite of many collectors and has been the focus of studies in the southeastern United States. Recent collecting has revealed significant new biological and distribution information for 33 cerambycid species. Included are five new state records and one new country record. Host plants are reported for the first time for 31 species. Unless otherwise stated all collections were made by the author. Rearing was done by collecting infested plant material and placing it in individual clear plastic tubs, which were checked regularly for emerging specimens. Moisture was supplied from a plastic spray bottle as …

Notes On Oriental Lamiini (Coleoptera: Cerambycidae: Lamiinae), Karl-Ernst Hüdepohl, Daniel J. Heffern

Insecta Mundi

Longhorned beetles of the Tribe Lamiini have evolved into approximately 180 genera in South East Asia and nearby regions. Many genera and species are poorly-known and some taxa are still undescribed. As a prelude to a checklist and further studies of this group, the authors propose some taxonomic changes and provide corrections to previous literature.

The private collection and literature of the senior author are deposited in Zoologische Staatssammlung Munchen, Munchhausenstrabe 21, D-8000, Munchen, Germany.

A New Species Of Ceroplastes From Florida (Hemiptera: Coccoidea: Coccidae), Greg Hodges

This number has grown recently with the establishment of the Ceroplastes rusci and the discovery of C. feltyii (new species). A description and illustration of C. feltyii is provided along with a key to all of the wax scales currently found in Florida.

Three Bostrichid Beetles New To Florida (Coleoptera: Bostrichidae), Robert L. Beiriger

Insecta Mundi

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. …

Luchoelmis, A New Genus Of Elmidae (Coleoptera) From Chile And Argentina, P. J. Spangler, C. L. Staines

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 …

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 …

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 …

A Review Of Poanes Hobomok (Hesperiidae: Hesperiinae), With The Description Of A New Subspecies From The Southern Appalachians, Ronald R. Gatrelle

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 …

Morphology Of The Minute Larva Of Ptinella Tenella, With Special Reference To Effects Of Miniaturisation And The Systematic Position Of Ptiliidae (Coleoptera: Staphylinoidea), Vasily V. Grebennikov, Rolf G. Beutel

All Peer-Reviewed Publications

External and internal features of minute reared ex ovo larvae of Ptinella tenella Erichson with the head widths ranging from 108 to 138 μm are described. In total 139 setae (trichoid sensilla), 18 pores (non-trichoid sensilla), and 60 muscles were identified. The complexity of the chaetotaxy, the musculature of the head, the tentorium, and the digestive tract are not affected by the extremely small size of the larvae. Specific features, which may have resulted from miniaturisation are the elongate shape of the brain reaching the mesothorax posteriorly, the reduced condition of the thoracic sclerites and endosternites, the simplified musculature of …

Relative Safety Of Sprays Of Two Neem Insecticides To Diadegma Mollipla (Holmgren), A Parasitoid Of The Diamondback Moth: Effects On Adult Longevity And Foraging Behaviour, A. M. Akol, S. Sithanantham, P. G.N. Njagi, A. Varela, J. M. Mueke

All Peer-Reviewed Publications

The non-target safety of two neem-based insecticides, Neemroc EC® (an oil formulation) and Neemros® (an oil-free powder formulation) to adults of Diadegma mollipla (Holmgren), a larval parasitoid of the diamondback moth, Plutella xylostella (L.), was investigated in laboratory bioassays. The neem insecticides were compared against Karate® (a synthetic pyrethroid insecticide) and water as sprays. Karate® caused 100% mortality in treated wasps within 6 h, while the two neem insecticides did not cause any significant mortality. The mean longevity of wasps was not significantly affected by exposure to the two neem insecticides. The time allocation to different components of foraging behaviour …

High-Temperature Controlled Atmosphere For Post-Harvest Control Of Indian Meal Moth (Lepidoptera: Pyralidae) On Preserved Flowers, Jodi A. Sauer, Mark D. Shelton

Office of the Dean (CAFES) Scholarship

High carbon dioxide atmospheres combined with high temperature were effective for controlling Indian meal moth, Plodia interpunctella (Hübner) pupae. Pupae were exposed to atmospheres of 60, 80, or 98% carbon dioxide (CO₂) in nitrogen (N₂), or 60 or 80% CO₂in air at temperatures of 26.7°C or 32.2°C and 60% RH. Controlled atmosphere treatments at 32.2°C controlled pupae faster than the same treatments at the lower temperature. At both temperatures high CO₂ concentration treatments combined with nitrogen killed pupae faster than high CO₂ concentration treatments combined with air. Exposure to 80% carbon dioxide …

Evaluation Of Buffalograss Germplasm For Resistance To Blissus Occiduus (Hemiptera: Lygaeidae), Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan, John E. Foster

Department of Entomology: Faculty Publications

Blissus occiduus Barber has emerged as an important insect pest of buffalograss, Buchloe dactyloides (Nuttall) Engelmann, in Nebraska. This research evaluated selected buffalograss germplasm for resistance to B. occiduus. Eleven buffalograss selections were screened for chinch bug resistance in three greenhouse studies and two field evaluations. Based on chinch bug damage, NE91-118, ‘Tatanka’, ‘Bonnie Brae’, and ‘Cody’ were rated highly to moderately resistant. These four buffalograsses exhibited minimal damage, even though all were heavily infested with chinch bugs. NE84-45-3 and ‘378’ were highly susceptible to B. occiduus. Field evaluations confirmed chinch bug resistance ratings under field conditions. NE91-118 …
