The Effects Of Extrinsic And Intrinsic Factors On The Reproductive Biology Of Male Western Bean Cutworm Moths, Striacosta Albicosta (Smith), Jasmine Farhan
Electronic Thesis and Dissertation Repository
Pheromones are important in the mating systems of nocturnal moths as they are relied on to find and/or assess mates. Extrinsic and intrinsic factors have been shown to influence female emission of and male response to pheromones. My thesis focuses on the reproductive biology of males of the western bean cutworm, Striacosta albicosta, a pest of beans and corn that has recently began expanding its range eastwardly. I conducted a field-based experiment to determine the effects of extrinsic factors on pheromone trap catches. I also conducted laboratory based mating experiments to determine the effect of male age on acceptance …
Microbial Gut Diversity Of Africanized And European Honey Bee Larval Instars,

Microbial Gut Diversity Of Africanized And European Honey Bee Larval Instars, Svjetlana Vojvodic, Sandra M. Rehan, Kirk E. Anderson
Faculty Scholarship for the College of Science & Mathematics
The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming increasingly apparent, there is very little and inconsistent information concerning symbiotic bacterial communities in honey bee larvae. The larval gut is the target of highly pathogenic bacteria and fungi, highlighting the need to understand interactions between typical larval gut flora, nutrition and disease progression. Here we show that the larval gut is colonized by a handful of bacterial groups previously described from guts of adult honey bees or other pollinators. …

Evaluation Of The Efficacy Of 1-Octen-3-Ol And Carbon Dioxide Chemoattractants With Mosquitoes And Bloodmeal Analysis Of Culex Mosquito Spp. In Lancaster County, Nebraska, Julianne N. Matczyszyn
Department of Entomology: Dissertations, Theses, and Student Research
The purpose of mosquito-borne disease surveillance is to assess the risk of pathogen transmission by assessing mosquito populations and the prevalence of disease pathogens in those populations. West Nile virus (WNV) is an important mosquito-borne virus in Nebraska, and can be transmitted by several mosquito species found in Lancaster County, Nebraska, including Culex pipiens L., Culex salinarius Coquillett, Culex restuans Theobald, Culex tarsalis Coquillett, Culex territans Walker, and Culex erraticus Dyar & Knab. These species are ornithophilic, yet many studies indicate a shift in host feeding to mammalian in late summer months. One-octen-3-ol (octenol) can be isolated …

Previous molecular analyses of higher hymenopteran relationships have largely been based on subjectively aligned ribosomal sequences (18S and 28S). Here, we reanalyze the 18S and 28S data (unaligned about 4.4 kb) using an objective and a semi-objective alignment approach, based on MAFFT and BAli-Phy, respectively. Furthermore, we present the first analyses of a substantial protein-coding data set (4.6 kb from one mitochondrial and four nuclear genes). Our results indicate that previous studies may have suffered from inflated support values due to subjective alignment of the ribosomal sequences, but apparently not from significant biases. The protein data provide independent confirmation of …

Effects Of A Corn Root Defense Substance On Western Corn Rootworm Diabrotica Virgifera Virgifera Leconte Larvae, Zixiao Zhao
Department of Entomology: Dissertations, Theses, and Student Research
The objectives of this research were to evaluate the effects of hydroxamic acids, a group of corn root defense substances on western corn rootworm (Diabrotica virgifera virgifera LeConte) larvae and identify putative molecular mechanisms for hydroxamic acid detoxification. Corn line 428G carries a homozygous mutant bx1 gene, which makes it unable to synthesis hydroxamic acids. In contrast, H88 is the wild type parental line of 428G and is able to synthesize hydroxamic acids. Larvae were fed on 428G and H88 roots for 7 days for comparison. No significant difference was observed in growth, development, or survival rate. A RNA-Sequencing …

Cold Tolerance Of The Eastern Subterranean Termite, Reticulitermes Flavipes (Isoptera: Rhinotermitidae), In Ontario., Matthew W. Clarke, Graham J. Thompson, Brent J Sinclair
Biology Publications
We characterized the cold tolerance of natural populations of the Eastern subterranean termite (Reticulitermes flavipes (Kollar) [Isoptera, Rhinotermitidae]) in southwestern Ontario, Canada. We measured cold tolerance in workers from six colonies of termites established from Pelee Island in Lake Erie, and Point Pelee National Park. The mean critical thermal minimum, at which termites entered chill coma, ranged from 8.1 to 5.7°C. Mean supercooling points (SCP, the temperature at which individuals freeze) ranged from -4 to -4.6°C, and did not differ significantly between colonies, nor was SCP dependent on body size. Individuals survived brief exposure to low temperatures, as long as …

Frequency And Distribution Of Extended Diapause In Nebraska Populations Of Diabrotica Barberi (Coleoptera: Chrysomelidae), Ryan W. Geisert, Lance J. Meinke
Department of Entomology: Faculty Publications
The frequency of extended diapause in populations of the northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae), was measured in eastern Nebraska. Adult collections were made during late summer in 2008 and 2009 from eight sites each year (seven sites were consistent over years). Eggs were obtained from 12 to 20 females per site and were held on moist soil under appropriate temperature profiles to facilitate egg survival, diapause development, and diapause termination. Percentage egg hatch was recorded after the first and second year for the 2008 and 2009 collections. Additional extended diapause expression was estimated for the …

The recent resurgence of bed bugs has led to an explosion of bed bug research influenced by the applied needs of pest management professionals. I assessed the needs of pest management professionals who deal with bed bugs in South Carolina. Bed bugs were reported in 28 of 46 counties in South Carolina. Previous samples of bed bug populations have displayed a 1:1 sex-ratio suggesting females do not use aggregations and harborages to hide from males and traumatic insemination, which can be harmful to females. Aggregations are biased in composition, suggesting that females are able to hide from males within harborages. …

Identification And Characterization Of Peak Activity, Environmental Variables, And Bacterial Pathogens In A. Americanum L. At Ames Plantation, West Tennessee, Brian Hendricks
Masters Theses
The status of tick-borne diseases (TBD) in the southeastern United States is uncertain due to a number of factors including, but not limited to emerging pathogens, misdiagnoses, and modifications to landscapes. Ehrlichiosis and rickettiosis are two of the most common TBDs; these are caused by Ehrlichia and Rickettsia bacteria that can be transmitted by a number of different tick species. The objectives of this study were to identify Amblyomma americanum (the Lone Star tick) peak activity and habitat preferences and characterize the potential role of A. americanum in tick-borne disease cycles in southwestern Tennessee. Using vegetation drags and CO2 …

A three-year study (2009-2011) was conducted to examine the spatial and temporal dynamics of stink bugs in three commercial farmscapes in South Carolina and Georgia. Crops included wheat, Triticum aestivum (L.), corn, Zea mays (L.), soybean, Glycine max (L.), cotton, Gossypium hirsutum (L.), and peanuts, Arachis hypogaea (L.). Farmscapes were sampled weekly using whole-plant examinations for corn, with all other crops sampled using sweep nets. The predominant pest species of phytophagous stink bugs were the brown stink bug, Euschistus servus (Say), the green stink bug, Chinavia hilaris (Say), and the southern green stink bug, Nezara viridula (L.). Chi-square tests indicated …

Squash bug (Anasa tristis) is a “true bug” with piercingsucking mouthparts (Order Hemiptera) in the leaffooted bug family (Coreidae). It is common throughout the U.S. and found from Canada to Central America. Adults (Fig. 1) emit a foul odor when disturbed and may be called “stink bugs”; however, true stink bugs are in a different true bug family.
