Abstract:Goriška regija z Novo Gorico je zaradi milega podnebja in prehodne lege ugodno okolje za tujerodne vrste, tako rastlinske kot živalske. V zadnjih letih je invazivna vrsta tigrastega komarja (Aedes albopictus Skuse, 1894) na tem območju naselila areal, v katerem se nemoteno razmnožuje in vzdržuje stalno populacijo. V diplomskem delu smo se odločili spremljati letno dinamiko pojavljanja jajčec in ličink komarjev na različnih lokacijah mestnega, primestnega in gozdnega okolja. S preverjanjem prisotnosti ličink tigrastega komarja na različnih lokacijah smo poskušali dobiti odgovor na to, kje se nahajajo za to vrsto ugodni mikrohabitati. Rezultati so bili pridobljeni s pomočjo pasti, s katerimi smo spremljali številčnost ličink v okolju. Ob zaključku smo preverili še razmerje med številom ličink avtohtonih vrst komarjev in ličink tigrastega komarja. Dobljene vrednosti smo primerjali med seboj, ugotavljali dinamiko razmnoževanja in določali območja, ki jih ta vrsta v večjem številu naseljuje. Iz raziskave smo ugotovili, da tigrasti komar na tem območju naseljuje predvsem urbane habitate, manj pa je zastopan v gozdovih. Začetek pojavljanja prvih ličink smo zabeležili v drugi polovici maja, njihovo število je strmo naraščalo do julija, ko smo raziskavo tudi zaključili. Največje število ličink na vseh vzorčnih mestih je pripadalo tigrastemu komarju, manj pa je bilo avtohtonih vrst komarjev. Med preučevanimi potencialnimi razmnoževalnimi habitati smo daleč največjo številčnost ličink tigrastega komarja zaznali v peskolovih.

Title:REPRODUCTION OF TIGER MOSQUITO (Aedes albopictus) IN NOVA GORICA
Abstract:The Goriška region and the town of Nova Gorica itself are a hotspot for reproduction and further spreading of many plant or animal non-native species. The reason for this are its transitional position and its mild climate. In recent years an invasive species known as the tiger mosquito (Aedes albopictus Skuse, 1894) has colonized this area. Here it successfully reproduces and maintains its population. In this paper we studied the seasonal dynamics of its reproduction from the appearance of first eggs until the development of the species' larvae in various urban, suburban and forested locations. We studied the presence of tiger mosquito larvae in different surroundings and tried to determine its most suitable microhabitat. In order to acquire appropriate results we used ovitraps, which are commonly used to monitor mosquito larvae in their natural environment. At the end we examined the ratio between larvae of indigenous species and tiger mosquito larvae. The data were compared to shed light on its reproductive dynamics and to identify habitats that are advantageous for this species. Results demonstrate that the tiger mosquito prefers urban habitats to forested areas. The larvae started to appear in the second half of May. Their numbers were growing exponentially until July when we concluded our research. The analysis of data from selected locations indicates that tiger mosquito larvae dominate the larvae of indigenous species in all locations. The highest number of larvae in urban environments was found in sand traps for rainwater.
