We revealed that *Ae. geniculatus* is highly susceptible to CHIKV infection and could transmit the virus. By specifically exploring the vector competence dynamic in *Ae. geniculatus* and *Ae. albopictus* mosquito species, we revealed that the cumulative distribution of CHIKV incubation period in *Ae. geniculatus* was delayed by several days as compared to *Ae. albopictus*.
