Master Thesis on Thursday Sep 30, 2021 at 11:00 Place: IFISC Seminar Room Title: A compartmental model for vector transmitted diseases: an application to Xylella fastidiosa Speaker: Rosa Flaquer Galmés, IFISC Abstract: <p>In 2016 the presence of the bacterium Xylella fastidiosa was detected in Majorcan almond trees<br /> and was regarded as the causal pathogen agent of the mortality of these trees over the last fifteen<br /> years. Xylella fastidiosa, being endemic of the Americas, is an insect-transmitted bacterium which<br /> is considered one of the major threats to plants worldwide for its large number of hosts, strains<br /> and potential vectors. By 2017 the reported incidence of the bacterium over Majorcan almond<br /> trees was 79.5% &plusmn; 2.0, presenting a great danger to one of the historical crops of the Balearic<br /> Islands. then, the aim of this project is to develop a first step on the study of this epidemic by<br /> means of a deterministic compartmental (mean-field) model. In particular, we present a model<br /> for the vector assisted transmission of the pathogen, performing an analytical and computational<br /> analysis. The model incorporates the specific biological and epidemiological considerations of the<br /> bacterium Xylella fastidiosa and its interactions with insects and hosts in Majorca Island. In our<br /> work the vector (insect) population varies with time, mimicking the field observations. One of the<br /> conclusions is that, in general, this temporal variation hinders the theoretical characterization of<br /> epidemic thresholds.<br /> Advisor: Manuel Matias<br /> Jury: Jose J.
