Migratory routes and times

By combining molecular studies, experts have managed to establish the migratory routes of this species. According to their conclusions, the first presence of the wasp outside its native habitat was recorded in New Zealand in 1900, and the next one was recorded in Australia in 1961. Its advance continued from Europe and Oceania towards South America, where it settled in Uruguay in 1980, Argentina in 1985, and Chile in 2001. From the Southern Cone and Oceania, the wasp reached South Africa in 1994. The next migration took place from Europe and South America towards the United States and Canada where it settled in 2004 and 2005, respectively.

To conduct this research, the researchers have genetically studied 500 specimens of the Sirex noctilio. The specimens captured on the Iberian Peninsula were analysed by the Basque Institute for Agricultural Research and Development, Neiker-Tecnalia.
