Abstract:

The ability of phytoseiids for inducing plant defensive responses was studied. First, the activation of citrus defense pathways in two rootstocks with different resistance to Tetranychus urticae, Citrus aurantium and C. reshni, was analysed. Metabolomic analyses showed that the jasmonic acid, salicylic acid and flavonoids defense pathways were modified depending on plant genotype and phytoseiid diet specialization. Second, attraction and repellence of volatiles released by citrus infested by phytoseiids was studied. This depended on the species of the predator triggering these responses. We al

Abstract:

Plant-based defence mutualisms involve aspects of plant morphology that influence the performance of plant parasites, their natural enemies and trophic interactions. Leaf domatia, small indentations on the underside of leaves, can be structurally complex, and are often inhabited by potentially beneficial mites and other arthropods. Plant morphological traits such as domatia that enhance mutualistic relationships may result in increased plant growth rates, and reproductive success. New Zealand supports ~60 plant species that have domatia, the most speciose genus being Coprosma. The aim of this

Thesis (MSc (Plant Pathology))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: Dry core rot (DCR) and wet core rot (WCR) are among some of the most important postharvest diseases of apples in South Africa. Mouldy core (MC) is also a symptom associated with the core region of apples, but it is not of economical importance since apple tissue surrounding the core region is not affected as is the case with DCR and WCR. The incidence of core rots in harvested fruits can be as high as 12%, but in general ranges from 3 to 8%. Infections and losses can also occur during fruit handling in

The predatory mite, Phytoseiulus persimilis, is a commercially-available predator that is commonly used to control twospotted spider mites on greenhouse crops; but its efficacy varies among crops, and it is generally ineffective at low prey densities. In general, predator foraging efficiency depends on how well predators find prey patches, the length of stay in prey patches, and consumption of prey while in pr

Abstract:

Spider mites (Acari: Tetranychidae) are an important agricultural pest of many crops and landscape plants. They can reproduce rapidly and quickly develop resistance to many pesticides, making them difficult to manage. Plant water-stress and high temperatures promote spider mite infestations, while spider mite outbreaks can also result from neonicotinoid insecticide applications. Drought is predicted to increase in the Intermountain West due to increases in temperature and reduced frequency of precipitation events in the region, and neonicotinoids are currently one of the most widely used class

Abstract:

Invasive plant species threaten native plant communities and inhibit efforts to restore disturbed landscapes. Surface coal mines in the Appalachian Mountains are some of the most disturbed landscapes in North America. Moreover, there is not a comprehensive understanding of the land cover characteristics of post- mined lands in Appalachia. Better information on mined lands' vegetative cover and ecosystem recovery status is necessary for implementation of effective environmental management practices. The invasive autumn olive (Elaeagnus umbellata) is abundant on former coal surface mines, often

Abstract:

Aloe mites are herbivores of the genus Aloe (ALOACEAE) and are associated with hyperplastic growth in various aloe species, but the biochemistry of this interaction is poorly understood. In an effort to characterize plant defense responses to herbivory in the genus Aloe, a salivary extract was isolated from aloe mites (Aceria aloinis Keifer) and its bioactivity was tested using a hypocotyl elongation assay. Subsequently, Aloe striata plants were treated with jasmonic acid (JA), salicylic acid (SA), and the mite salivary extract. Using water and methanol, compounds of different polarity were ex

Abstract:

<p> Growing crops for biofuel production on agricultural land has caused a debate between whether we should grow corn grain on productive, agricultural lands to feed a growing human population or to fuel our vehicles. This has increased interest in growing cellulosic biofuel feedstocks on marginal lands. Switchgrass (<i>Panicum virgatum</i> L.), a warm-season perennial grass, has been shown to be a viable bioenergy crop because it produces high yields on marginal lands under low water and nutrient conditions. West Virginia contains immense acreages of reclaimed surface mine lands and could off

Abstract:

<p> The high cost and environmental risks associated with non-renewable energy sources has caused an increased interest in, and development of renewable biofuels. Switchgrass (<i>Panicum virgatum</i> L.), a warm season perennial grass, has been investigated as a source of biofuel feedstock due to its high biomass production on marginal soils, its tolerance of harsh growing conditions, and its ability to provide habitat for wildlife and soil conservation cover. West Virginia contains vast expanses of reclaimed surface mine lands and could potentially benefit from the production of switchgrass a

Le développement de la théorie de Hodge a permis une compréhension plus profonde de nombreux invariants topologiques dans le cadre de la géométrie algébrique complexe. Dans ce travail de thèse, nous nous proposons de géométriser la notion de structure de Hodge mixte (SHM). Dans ce but, nous généralisons la construction de Rees et son inverse qui permettent d'associer anneaux gradués et anneaux filtrés par une chaîne d'idéaux. Nous établissons des équivalences entre catégories d'espaces vectoriels filtrés munies de morphismes strictement compatibles et catégories de faisceaux cohérents équivari

Abstract:

The predatory mite Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is a key player in the biological control of pests in greenhouse crops. However, on tomato crops, the release of A. swirskii does not provide effective pest control, as it cannot become established. In summary, this study concludes that the acyl sugars produced by tomato trichomes are detrimental to the phytoseid A. swirskii, and this information can serve as a basis for future research in plant breeding programs, with the aim of a successful application of phytoseids for the protection of tomato crops.

Abstract This thesis deals with the Holocene development of palsa mires in continental Europe, especially permafrost dynamics and its consequences on vegetation succession and peat accumulation. Peat deposits of four permafrost mires in boreal and subarctic northeastern European Russia and in northern oroboreal Finland have been studied using plant macrofossil analysis, (AMS) radiocarbon dating, dry bulk density and carbon content measurements. In addition, preliminary results are available from another palsa mire in northeastern European Russia. Modern vegetation has been investigated to supp
