Abstract:Tigrasti komar, Aedes albopictus (Skuse, 1895), je invazivna tujerodna vrsta komarjev, ki je v Sloveniji prisotna že 16 let. Zaradi svojega hitrega širjenja, sposobnosti izkoraiščanja umetnih vodnih habitatov za svoj razvoj, nadležnosti za prebivalstvo ter predvsem nevarnosti prenosa različnih zoonoz ima izjemen pomen za javno zdravje. Namen doktorske disertacije je bil določiti razširjenost tigrastega komarja v celotni državi ter preučiti njegovo potencialno razširjenost v bližnji prihodnosti. Popisi komarjev so temeljili na iskanju ličink v različnih vodnih habitatih. Komarje smo do vrste določili na podlagi morfoloških znakov ter s pomočjo DNA (deoksiribonukleinska kislina) črtnih kod. V dveh letih vzorčenja smo ugotovili stabilno populacijo tigrastega komarja na Primorskem, v Ljubljani in širši okolici ter na Dolenjskem. Ob popisu tigrastega komarja smo naleteli še na dve invazivni vrsti, japonskega komarja, Ae. japonicus japonicus, ter korejskega komarja, Ae. koreicus. Zaradi hitro rastoče populacije, pomena za javno zdravje ter nejasnih ekspanzijskih mehanizmov japonskega komarja v Evropi smo dodatno opravili populacijsko študijo te vrste na osnovi genetskih markerjev. Genotipizirali smo sedem mikrosatelitnih lokusov na reprezentativnem številu vzorcev in obenem sekvenirali del njihovega mitohondrijskega gena za nikotin-dehidrogenazo; NAD4. Rezultati so pokazali, da so populacije v Sloveniji najbolj podobne populacijam, ki naseljujo območje Nemčije. S to raziskavo smo dokazali, da sta populaciji tigrastega in japonskega komarja simpatrični na velikem delu Slovenije. Na podlagi zbranih podatkov o njuni razširjenosti, različnih kombinacij bioklimatskih spremenljivk iz dveh baz, WorldClim in CHELSA, in nadmorske višine smo v računalniškem programu MaxEnt izdelali različne modele potencialne razširjenosti za obe vrsti. Najboljši modeli so bili izbrani na podlagi AIC in AUC vrednosti. Kot primernejši za napovedi razširjenost obeh vrst se izkazali modeli s spremenljivkami iz baze CHELSA, kar smo potrdili tudi s terenskimi podatki. Tigrati komar lahko po napovedih modelov potencialno naseli še območje v severovzhodni Sloveniji, zato bi morali v prihodnosti temu nameniti pozornost, da bi preprečili naselitev in ustalitev vrste. Populacija japonskega komarja se je v primerjavi s tigrastim komarjem v času vzorčenja razširila na večino države, kar so predvedili tudi izdelani modeli. S študijo smo potrdili, da so modeli uporabno orodje za predvidevanje razširjenosti invazivnih vrst komarjev in bi jih lahko uporabili za preprečevanje širjenja invazivnih komarjev v prihodnosti v drugih državah s podobnimi bioklimatskimi pogoji.

Title:Dispersial capacity of Asian tiger mosquito, Aedes albopictus (Diptera: Culicidae), an invasive species in Slovenia
Abstract:The invasive Asian tiger mosquito, Aedes albopictus (Skuse, 1895), is present in Slovenia for 16 years. It is of great concern for public health due to its rapid spreading, easy exploitation of new habitats, its painful bites and the ability to transfer various diseases. The aim of this study was to determine the presence of Asian tiger mosquitoes throughout the country and to examine its potential distribution in near future. We based mosquito catches on the search for their larvae in various water contaitners. Caught mosquitoes were determined to the species level according to their morphological character or with the help of DNA barcoding. During the two years of sampling, we found an established population of Asian tiger mosquitoes in the Primorska and Dolenjska regions and in Ljubljana and its surroundings. Apart from Asian tiger mosquito, we confirmed the presence of two additional invasive mosquito species, i.e. Asian bush mosquito Ae. japonicus japonicus and Ae. koreicus. Because of rapidly expanding Asian bush mosquito's population, its importance for public health and unclear paths of spread in Europe, we additionally carried out a population study of this species. We genotyped seven microsatellite loci from a representative number of specimens and sequenced part of their mitochondrial gene NAD4. According to obtained results Slovenian populations are linked to the German ones. Our study confirms that the Asian tiger mosquito and Asian bush moquito are co-occuring in a large part of the country area. Based on collected data on their presence, various combinations of variables from two sets of bioclimatic layers, WorldClim in CHELSA, and altitude, we produced different models of potential distribution for both species. We used MaxEnt for the production of models. The best modeks were selected according to AIC in AUC values. Produced models with variables from the CHELSA database proved to be more suitable for the prediction of both species distribution, which was confirmed by field data. According to the models, the Asian tiger mosquito can potentially become established additionally in the North-Eastern Slovenia. In order to prevent its establishment, in the future special attention on its occurence and control should be made in this area. The population of Asian bush mosquito expanded to almost whole country during the study, which was anticipated by produced models. We proved that the models are a reliable tool to predict the expansion of invasive mosquito species and they could be used for future prevention of invasive mosquitoes spreading in other countries with similar bioclimatic conditions.
