Biological invasions, particularly those of xylophagous insects such as cerambycids, are constantly increasing, mainly due to climate change and the intensification of trade exchanges. These insects, primarily transported through international wood trade, establish themselves in new ecosystems where they may not have natural enemies. Once established, they can cause considerable damage to forests and urban areas, thus threatening biodiversity, the economy, and the health of ecosystems. Therefore, these invasions require rigorous monitoring and management to prevent and mitigate their devastating impacts.In this context, this thesis has the following main objectives: (i) to assess the effectiveness of metabarcoding, a method that allows for the simultaneous and rapid identification of multiple insect species collected in the same trap, using the MinION sequencer from Oxford Nanopore®. This sequencer has the advantage of being portative and inexpensive, making it more accessible than competing technologies. (ii) To create a reference library of molecular barcodes for European Cerambycids to provide the scientific community with a database for reliable DNA-based identification analyses. (iii) To study the genetic structure of invasive populations of an exotic species introduced from Asia to the Mediterranean basin (Xylotrechus stebbingi) to better understand the invasion dynamics of this insect native to Asia. Regarding the first objective of this thesis, our results showed that the MinION sequencer from Oxford Nanopore® was efficient for the rapid detection and identification of invasive species, in comparison to Illumina® and IonTorrent sequencing technologies. Our results also show that the trapping method and sample preservation in the traps are essential prerequisites for the reliable detection of species present in the samples. For the second chapter, we assembled 2928 DNA barcode sequences from 147 species of cerambycids, representing over 79% of the 185 species captured in Europe using multi-pheromone traps. This new database could be used to accurately identify the contents of multi-pheromone traps deployed in Europe during barcode or metabarcoding analyses. Finally, in the third chapter of this thesis, we demonstrated that the invasion of the xylophagous Xylotrechus stebbingi in the Mediterranean basin resulted from a series of multiple introductions, probably linked to maritime trade exchanges rather than a single introduction that would have spread over time. These results imply that this highly polyphagous species has a strong invasive potential and is likely to invade new regions of the world (outside the Mediterranean basin) in the coming years through maritime transport. Consequently, it is necessary to remain vigilant in port areas to limit the spread of this insect as much as possible

Despite the fact that Carpobrotus edulis and C. Affine acinaciformis have been introduced in southern France for over 200 years, few studies have addressed the invasion processes of these South Africa succulents. Investigations of their genetic traits, reproductive systems, a high frequency of hybridization, native pollinators, seed dispersal by introduced mammals, as well as links with insularity, suggest that the invasion by Carpobrotus spp. Is a complex and evolutionary phenomenon which results in profound changes of the invaded ecosystems. The latter includes a decrease in the percent abundance of various plant groups, soil transformation in the case of C. Affine acinaciformis, a restructuration of pollinator webs, and facilitation with introduced mammals. The fact that C. Edulis is more common in south east France compared to C. Affine acinaciformis can potentially be explained by genetic and reproductive differences between the two taxa. Recurrent indications of hybridization could partly explain the invasive nature of these two alien plants, their differences with populations from their native distributions, as well as their strong evolutionary potential and the possibility of polyploidization. Together, these results suggest that the evolutionary biology of invasive species is necessary for a better understanding of the invasion process and contemporary evolution

The invasion by the land snail Xeropicta derbentina is spectacular because this species forms many very large populations. Native of eastern Mediterranean, X. Derbentina has been introduced in France in the forties. The invasion was limited to the of Aix-en-Provence region during the sixties, but now affect the overall Provence and even the Hautes-Alpes and the right bank of the Rhone. X. Derbentina colonizes dry grasslands, abandoned lands, pastures and man-modified lands up to 900 m above the sea level. The spreading of X. Derbentina seemed to be favoured by its active dispersal ability (18m during six months) and by human activities as vectors of passive dispersal. .
