Fig 1.
Location and collection year of traps.
Green, yellow, blue, red, orange are the traps collected in 2006, 2007, 2008, 2009, 2010 respectively.

Results of statistical modeling.
Fig 2.
Relationship between proportion of positive traps and distance to main colonized area (red line) and to area colonized sporadically (“jump”, blue line).
The x-axis is in km. The gradual relationship shown on the red line suggests an invasive wave. Conversely, abrupt drop of the blue line suggests that such “jump” did not result so far in a new front of invasion. Curves have been fitted through loess algorithm.
Fig 3.
Positive traps observed (A,B) and model predictions (C,D) for 2012.
(A,C) First semester; (B,D) Second semester. Values range from probability of 0% to observe Ae. albopictus (blue) to 100% (red).
Fig 4.
Prediction of probability of presence of Aedes albopictus in 2013 (A,B) and 2014 (C,D) for the first and second semesters (A,C and B,D respectively).
Values range from probability of 0% to observe Ae. albopictus (blue) to 100% (red).
