  1. The table refers to the hatching characteristics of Ae. aegypti and Ae. albopictus from Mayotte and the Reunion Island infected with two CHIKV strains: CHIKV E1-226A and CHIKV E1-226V. N corresponds to the number of female analysed, SD to the standard deviation, 1 and 2 to respectively, trial 1 and trial 2, DINF to females with disseminated infection, NDINF to females with non-disseminated infection, and NI to non-infected females.
