Population genetic structure of the Asian bush mosquito, Aedes japonicus (Diptera, Culicidae), in Belgium suggests multiple introductions

Abstract: Background Aedes japonicus japonicus has expanded beyond its native range and has established in multiple European countries, including Belgium. In addition to the population located at Natoye, Belgium, locally established since 2002, specimens were recently collected along the Belgian border. The first objective of this study was therefore to investigate the origin of these new introductions, which were assumed to be related to the expansion of the nearby population in western Germany. Also, a… Show more

“…However, although Culex pipiens is not considered a primary vector, given its high abundance in temperate zones (including Europe) and its competence for JEV, the potential contribution of this vector species to the spread of JEV upon introduction should not be underestimated. In this respect, Aedes japonicus also might play a role as it is known to be abundant in certain regions [ 123 , 124 , 125 , 126 , 127 ] and present far beyond its endemic zone ( Figure 3 ). It is one of the world’s most invasive Culicidae species, with a confirmed presence in Europe.…”

“…The collected polystyrene pieces from OT were checked for the presence of IMS eggs in the laboratory by using a stereomicroscope. From 2007 to 2010 and from 2013 to 2019, a subsample of the eggs from the polystyrene piece (1–5 eggs per side) was always DNA-barcoded [ 18 , 26 , 27 , 36 , 40 ]. In 2012 and 2020 the positive polystyrene pieces or wooden paddles were immerged in water in secured containers, which were stored in a secured mosquito breeding room (2012 [ 25 ]) or climate controlled cupboard (2020).…”

“…japonicus spread again in southwest direction as it was the case in 2012. It seems that the small forest located southwest of the tyre company forms a good ‘green corridor’ for the spread of the mosquito [ 40 , 72 ]. At the northeast side, the company is surrounded by open meadows, which possibly hamper the spread of the population in that direction.…”
