Adaptation to temperate climates: Evidence of photoperiod-induced embryonic dormancy in Aedes aegypti in South America.

•Short parental photoperiod inhibited the hatching response of Aedes aegypti eggs.•The hatching response increased with eggs age up to four months.•No effect of the storage photoperiod on the hatching response was detected.•The hatching response was highly variable among egg batches from different females.
