Outbreaks of spider mites (Acari: Tetranychidae) in vineyards have been increasing with the expansion of the industry in Virginia. Only three effective acaricides are registered on grapes and as resistance begins to occur, control options are limited. Biological control of spider mites by inoculative or inundative releases of predatory mites has been tried on a wide range of crops including grapes. This project examined the feasibility of using <i>Neoseiulus fallacis</i> (Acari: Phytoseiidae) as a potential large-scale biological control agent in vineyards. Slide dip bioassays were conducted on <i>N. fallacis</i> to determine the toxicity of insecticides, fungicides and herbicides commonly used on grapes in Virginia. In addition to laboratory experiments, commercially obtained <i>N. fallacis</i> were released in vineyards with spider mite infestations. The populations of both mites were then monitored on a regular basis to determine dispersal and distribution patterns. Among the insecticides tested in the laboratory bioassays, carbaryl, azinphos-methyl, phosmet, cyhexatin, and pyridaben all caused significantly higher mortality than the control treatment. Fungicides tested were not toxic to the predator, but three herbicides caused high mortality. Glufosinate caused 100% mortality after 24 hours and both oxyfluorfen and paraquat had adverse effects on <i>N. fallacis</i>. The use of materials that were found to be toxic to the predator would not be compatible with inoculative releases of <i>N. fallacis</i>. Field release results were variable. Three releases were made in 1999 and 2000., Recovery of the predator was low following the releases at two of the sites, probably due to lack of prey. At the third site enough predators were recovered to analyze the spatial distribution of the predator and prey populations. It appears that there is no similar aggregation pattern between the predator and prey at the same point in time although there is an indication of the predator spreading is response to the prey distribution. A more complete season of sampling would give more conclusive evidence of this trend. Although the distribution of the two populations were dissimilar, the predator was present throughout the season and did spread through the entire plot indicating that the predator may be able to colonize the vineyard if it successfully overwinters. / Master of Science

Jumping spiders (Family Salticidae) are known for their exceptional vision, including color vision and spatial acuity. Salticids use their vision in many behaviors, including predation and courtship. Recently evidence of their ability to sense airborne vibrations, i.e. sound, was published. I used a specialized jumping-spider-specific eyetracker to study the visual reaction of the retinas of the jumping spider Phidippus princeps when exposed to the sound of a predator. I used a generic wasp sound, previously shown to induce a startle response, as stimulus and played it from different directions. The spiders showed strong reactions to the sound stimulus by large increases in retinal movement when exposed to the stimulus, and they showed no habituation to the stimulus over three rounds of exposure. However, I found no indication that the direction of retinal movement corresponded to the location of the sound source. Future experiments may examine whether spiders are primed to search for particular types of images by cross-modal cues such as sound and if they can determine the direction of a sound source.

En esta tesina, investigo el arquetipo de la mujer araña . Empiezo en el primer capítulo con el prototípo--Aracne, joven tejedora de la mitología grecorromana, de cuyo nombre viene la raíz de todo lo “arácnido.” Según la fábula, Aracne, famosa tapicera, fue transformada en una araña por ofender a Minerva. Investigo el mito—como primero apareció, recordado por Ovidio en las Metamorfosis (8 a.D)--y su propia metamorfosis a lo largo de dos milenios. Me enfoco en la tradition exegética de L’ovide moralisé, nacida en Francia en el siglo XIV, como ejemplo del discurso moralista que ha envuelto a Aracne, y, por consiguente, la mujer araña. En el segundo capítulo, expongo, a grandes rasgos, el arquetipo de la araña que se ha desarollado. Pasando revista al arte y literatura hispánica tanto como lo francófono, estudio algunas representaciones claves de la mujer-araña. Ato los elementos en común para entretejer tres sub-arquetipos de la mujer araña: la blasfema (Aracne), la depredadora (Femme Fatale), y la storyteller (Grandmother Spider).En el tercer capítulo, propongo que El beso de la mujer araña presenta, refleja, cuestiona, invierte, y finalmente reconcilia estas tres caras para presentar una nueva version de la mujer araña. Es una historia de conciliación de polos opuestos, y también de re-lectura—igual que la de Aracne, y de toda la tradición araña.

abstract: Spider dragline silk is well known for its outstanding mechanical properties - a combination of strength and extensibility that makes it one of the toughest materials known. Two proteins, major ampullate spidroin 1 (MaSp1) and 2 (MaSp2), comprise dragline silk fibers. There has been considerable focus placed on understanding the source of spider silk's unique mechanical properties by investigating the protein composition, molecular structure and dynamics. Chemical compositional heterogeneity of spider silk fiber is critical to understand as it provides important information for the interactions between MaSp1 and MaSp2. Here, the amino acid composition of dragline silk protein was precisely determined using a solution-state nuclear magnetic resonance (NMR) approach on hydrolyzed silk fibers. In a similar fashion, solution-state NMR was applied to probe the "13"C/"15"N incorporation in silk, which is essential to understand for designing particular solid-state NMR methods for silk structural characterization. Solid-state NMR was used to elucidate silk protein molecular dynamics and the supercontraction mechanism. A "2"H-"13"C heteronuclear correlation (HETCOR) solid-state NMR technique was developed to extract site-specific "2"H quadrupole patterns and spin-lattice relaxation rates for understanding backbone and side-chain dynamics. Using this technique, molecular dynamics were determined for a number of repetitive motifs in silk proteins - Ala residing nanocrystalline &beta-sheet; domains, 3"1"-helical regions, and, Gly-Pro-Gly-XX &beta-turn; motifs. The protein backbone and side-chain dynamics of silk fibers in both dry and wet states reveal the impact of water on motifs with different secondary structures. Spider venom is comprised of a diverse range of molecules including salts, small organics, acylpolyamines, peptides and proteins. Neurotoxins are an important family of peptides in spider venom and have been shown to target and modulate various ion channels. The neurotoxins are Cys-rich and share an inhibitor Cys knot (ICK) fold. Here, the molecular structure of one G. rosea tarantula neurotoxin, GsAF2, was determined by solution-state NMR. In addition, the interaction between neurotoxins and model lipid bilayers was probed with solid-state NMR and negative-staining (NS) transmission electron microscopy (TEM). It is shown that the neurotoxins influence lipid bilayer assembly and morphology with the formation of nanodiscs, worm-like micelles and small vesicles. / Dissertation/Thesis / Ph.D. Chemistry 2014
