Effect Of Constant Temperatures On Germination, Radial Growth And Virulence Of Metarhizium Anisopliae To Three Species Of African Tephritid Fruit Flies, Susan Dimbi, Nguya K. Maniania, Slawomir A. Lux, Jones M. Mueke

All Peer-Reviewed Publications

The effect of temperature on conidial germination, mycelial growth, and susceptibility of adults of three tephritid fruit flies, Ceratitis capitata (Wiedemann), C. fasciventris (Bezzi) and C. cosyra (Walker) to six isolates of Metarhizium anisopliae were studied in the laboratory. There were significant differences among the isolates in the effect of temperature on both germination and growth. Over 80% of conidia germinated at 20, 25 and 30°C, while between 26 and 67% conidia germinated at 35°C and less than 10% at 15°C within 24 hours. Radial growth was slow at 15°C and 35°C with all of the isolates. The optimum temperature …

Partial Purification And Characterization Of A Methyl-Parathion Resistance-Associated General Esterase In Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae), Xuguo Zhou, Michael E. Scharf, Gautam Sarath, Lance J. Meinke, Laurence D. Chandler, Blair Siegfried

Department of Entomology: Faculty Publications

Increased hydrolytic metabolism of organophosphate insecticides has been associated with resistance among Nebraska western corn rootworm populations. In this study, resistance-associated esterases were partially purified by differential centrifugation, ion exchange, and hydroxyapatite column chromatography, with a final purification factor of 100-fold and recovery of approximately 10%. Kinetic analysis of the partially purified enzyme indicated that the K_m of the group II esterases was identical for the two populations, although V_max was consistently threefold higher in the resistant population. A putative esterase, DvvII, was further purified to homogeneity by preparative polyacrylamide gel electrophoresis. DvvII is a monomer with a …

A New Subspecies Of Cicindela Nevadica Leconte (Coleoptera: Carbidae: Cicindelinae) From The Badlands Of South Dakota, Stephen M. Spomer

University of Nebraska State Museum: Entomology Papers

A new subspecies of Cicindela nevadica LeConte, Cicindela nevadica makosika Spomer, is described from the South Dakota Badlands. Geographically, the population occurs at the periphery of the range of C. nevadica knausii Leng. However, this new population is geographically isolated from the nearest C. n. knausii populations, which occur ca. 100 air miles north and over 100 air miles south. Phenotypically, C. n. makosika appears most similar to C. n. tubensis Cazier from northeast Arizona. A possible threat to this population is habitat destruction by cattle.

Sunflower Beetle (Coleoptera: Chrysomelidae): Pattern Of Larval Distribution And Parasitism In Cultivated Sunflower Fields, Gary J. Brewer, Laurence D. Charlet

Department of Entomology: Faculty Publications

The sunflower beetle, Zygogramma exclamationis (Fabricius), is a major pest of commercial sunflower, Helianthus annuus L. (Asteraceae), in the Plains area of central North America. Although an economic injury level for the sunflower beetle has been determined, in-field distributions of the larvae and their natural enemies have not been described. Over a three year period, fields were sampled for sunflower beetle larvae and for larvae of the endoparasitoid, Myiopharus macellus (Reinhard). Sunflower beetle larvae were generally found to have aggregated distributions. Knowledge of the distribution pattern will allow the development of more efficient sunflower beetle sampling protocols. Parasitism rates of …

Mammals Of Carlsbad Caverns National Park, New Mexico, Kenneth N. Geluso, Keith Geluso

Bulletin of the University of Nebraska State Museum (1924–2023)

Carlsbad Cavern was established as a national park on 14 May 1930, after being designated as a national monument for nearly seven years. The park is located in southeastern New Mexico, and today it encompasses 189.3 km² (73.1 mi²). Eighty-eight percent of the park lies in the rugged Guadalupe Mountains, while 12% is located on relatively flat land along the base of the mountains. The park contains a variety of habitats ranging from desert scrub at the lowest elevations to coniferous woodlands on the highest summits. Five months after Carlsbad Cavern was declared a national monument, Vernon …

Characterizing Bean Pod Rot In Arkansas And Missouri, Jeremy H. Taylor, Craig S. Rothrock

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Green beans are an important crop grown for processing in both Arkansas and Missouri. Green beans are harvested mechanically using non-selective picking fingers. Harvested beans are then transported in bulk to processing plants that are located at various locations throughout the mid-South. Thus, the crop is managed for high quality, avoiding pod blemishes caused by insects and diseases. One of the consistent quality problems that affect Arkansas and Missouri green bean crops is pod rot. Two of the causal agents of pod rot that have been reported by researchers and vegetable companies alike are Pythium aphanidermatum and an unidentified Phytophthora …

Bees Associated With Louisiana Longleaf Pine Savannas, Chanda Sara Bartholomew

LSU Master's Theses

Longleaf pine savannas are perhaps the most threatened ecosystems in North America. Despite a well documented and highly diverse flora, little has been published on insects in general and, in particular, on bees that provide the valuable service of plant pollination. Thus, the aims of this study were to: 1) survey bees found in two savanna types in southeastern Louisiana; and 2) contrast the diversity and species composition of these two savanna types. An ancillary goal was to contrast two collecting protocols for bees in the savanna habitat. Overall, a total of 3,407 bees were collected representing 125 species. Of …

Volatiles Associated With Formosan Subterranean Termites And Related Methods Development, Paul Mclaughlin

LSU Master's Theses

An investigation was conducted to identify volatiles associated with active Formosan termites. Using a combined technique of short path thermal desorption-gas chromatography/mass spectrometry (SPTD-GC/MS), qualitative comparisons were made between compounds detected in treatments containing active Formosan termites versus those detected in controls without Formosan termites. Except for dimethyl disulfide, none of the compounds were consistently detected in the treatments but not the controls for the four termite groups tested. However, in each of the three groups that dimethyl disulfide was detected, dead termites that were decomposing along with active termites were present. Therefore, none of the compounds could be classified …

Bollworm (Lepidoptera: Noctuidae) Production From Alternate Host Crops And Their Contribution To A Non-Bollgard Cotton Refuge, Edward Ashley Peters

LSU Master's Theses

The bollworm’s, Helicoverpa zea (Boddie), inherent tolerance to the Bacillus thuringiensis toxin expressed in Bollgard® cotton and its ability to exploit numerous hosts has caused the Environmental Protection Agency to re-evalute the refuge component of the resistance management strategy. The goal of this project was to evaluate selected alternate host crops as supplemental non-cotton refuges for bollworm. The relative density, temporal occurrence, and life stage synchrony for bollworm larvae and adults was studied in Bollgard® cotton, Bollgard® cotton non-Bollgard® cotton, field corn, grain sorghum, and soybean. Native populations of bollworm larvae were monitored June to September during 2002 and 2003 …

Effect Of Cotton Aphids, Aphis Gossypii (Glover), On Cotton Plant Development And Yield Components, Robert Hankins Jones

LSU Master's Theses

The effect of cotton aphids, Aphis gossypii (Glover), on cotton plant development and yield was studied during 2000 and 2001. Tests were conducted at the Macon Ridge Station (Winnsboro, Louisiana) in 2000 and 2001, and at the Northeast Research Station (St. Joseph, Louisiana) in 2001. Tests were performed in irrigated and non-irrigated regimes using individual plant comparisons, micro-plots, and whole plots. In both years and at both locations, cotton aphid densities induced chlorosis, and a downward cupping of leaves during the infestation period. The insecticides, pymetrozine and thiamethoxam, were applied to control natural infestations of cotton aphids. Although pymetrozine and …

Plant Surrogacy: An Evaluation Of Its Use And Application In The Effort To Conserve Ground Dwelling Invertebrates, Kerry Leigh Ironside

Theses : Honours

A study conducted in the Ridges State Forest, Yanchep was designed to investigate the relationship between plant species richness, vegetation association and ground dwelling invertebrate species richness. Four plant communities were sampled at two scales of measurement. Two treatments were located in woodland and two in heath. Within each vegetation association, plant communities that were representative of both high and low species richness were selected. Three invertebrate orders, Araneae, Coleoptera and Araneae were sorted to morphospecies level. Ordinal richness was also investigated. Two-way ANOVAs indicated that there was no relationship between plant species richness, vegetation association· or the interaction between …

Interactions Of Insect Herbivory And Multiple Abiotic Stress Agents On Two Wetland Tree Species In Southeast Louisiana Swamps, Rebecca Faye Souther-Effler

LSU Doctoral Dissertations

Forested wetlands in Louisiana are hydrologically isolated from the Mississippi River, impounded by manmade structures, impacted by saltwater intrusion, and are sinking, resulting in more frequent flooding for longer periods. Additionally, defoliation of the two dominant trees, baldcypress (Taxodium distichum L. Rich) and water tupelo (Nyssa aquatica L.), occur frequently during spring. In Louisiana, the baldcypress leafroller, BCLR, (Archips goyerana Kruse) and the forest tent caterpillar, FTC, (Malacosoma disstria Hubner) defoliate up to 120,000ha of baldcypress-tupelo swamps. Restoration plans call for reintroducing Mississippi River water (diversions) to increase sediment elevation, promote natural regeneration, and enhance primary and secondary productivity. In …

Biology And Host Finding Of Predaceous Hister Beetles (Coleoptera: Histeridae) Associated With Ips Spp. (Coleoptera: Scolytidae) In Loblolly Pine (Pinus Taeda L.), William Pinson Shepherd

LSU Doctoral Dissertations

The most common predaceous Histeridae (Coleoptera) found associated with Ips engraver beetles (Coleoptera: Scolytidae) in Louisiana were Platysoma attenuata LeConte, Pla. cylindrica (Paykull), Pla. parallelum (Say), and Plegaderus transversus (Say). Seasonal abundance of histerids in flight traps coincided with Ips spp. activity in the area. Histerid adults arrived at loblolly pine (Pinus taeda L.) logs one wk after Ips attacks had begun. As a group, histerids exhibited a bimodal emergence pattern with the first peak occurring during Ips emergence and a second four wks later, indicating that they fed on bark beetles and associated organisms arriving later in the colonization …

Evaluation Of Injury And Management Strategies For Stink Bugs (Heteroptera: Pentatomidae) On Cotton, Gossypium Hirsutum L., Melissa Marie Willrich

LSU Doctoral Dissertations

The effects of brown stink bug, Euschistus servus (Say), and southern green stink bug, Nezara viridula (L.), feeding on pre-flowering, flowering, and senescing cotton, Gossypium hirsutum L., plants were evaluated in field studies. Vegetative stage seedlings and flower buds (squares) were not significantly injured by adults or nymphs of either species in no-choice studies. Brown stink bug adults induced boll abscission, and reduced seedcotton yield and seed germination in bolls accumulating „T 350, „T 550, and 101 to „T 600 heat units beyond anthesis, respectively. In free-choice tests, boll preference was evaluated during each of the initial five weeks of …

Integration Of Management Tactics For The Rice Water Weevil Lissorhoptrus Oryzophilus Kuschel With Particular Emphasis On Use Of Plant Resistance (Tolerance), Li Zou

LSU Doctoral Dissertations

Studies were conducted to test the hypothesis, significant benefits can be achieved for the management of rice water weevil, Lissorhoptrus oryzophilus Kuschel, by the use of rice varieties with low levels of host plant resistance coupled with the judicious use of cultural practices and insecticides. Tolerant traits of a current commercial variety of rice, "Bengal", was manifested consistently over multiple years. Study on rice growth as effected by weevil injury showed that pruning of root systems by larvae of weevil resulted in a decrease in tiller number and shoot biomass of rice plants in the vegetative stage of growth. Yield …

The Performance Of The Baldcypress Leafroller (Archips Goyerana Kruse, Lepidoptera: Torticidae) In Response To Fertilization, Thinning, And Genetic Variation In Host Baldcypress (Taxodium Distichum L. Richard), Crawford Wood Johnson

LSU Master's Theses

Mississippi River diversions into coastal Louisiana wetlands aim to provide nutrient inputs and slow the impacts resulting from saltwater intrusion. Baldcypress (Taxodium distichum L. Richard) exhibits significant intraspecific tolerance to salinity and is being developed for restoration projects. Two studies were conducted using five half-sibling families of baldcypress planted at two locations in southeast Louisiana to investigate the effects of nutrient additions, thinning, and phenology on the growth of the baldcypress leafroller (Archips goyerana Kruse, BCLR). In the Jeanfreau study, families were subjected to a control, low, and high level of fertilization simulating two-four years’ effects, respectively, from a Mississippi …
