“Interspecific” stands for crosses between female Ae. aegypti, La Réunion island strain and Ae. albopictus (strains from China, Italy, La Réunion island) and “conspecific” for control mating between male and female of the same species. Réunion*= male Ae. aegypti from La Réunion island. Numbers in parentheses represent the number of dissected females for insemination assessment. Different letters show significant differences between groups.
