Statistical analysis of vector competence parameters after exposition to the CHIKV strain. The effects of mosquito lines (AL_Combani, AL_Kaweni, AL_Moroni, AL_Beauvallon, AL_Praslin, AL_Providence, AL_Gilles, AL_Philippe or AG_Moroni, AG_TBassin) and days post exposure (7 or 14 dpe) were analyzed for each mosquito species separately (Ae. albopictus or Ae. aegypti). The significance of variables was determined using a GLM on the basis of the selected minimal model
