  abstract = {{B}ackground: {T}he diapause of {A}edes albopictus is maternally induced by photoperiod and initiates at the pharate larvae stage in eggs. {T}his pre-diapause results in enhanced survival eggs during the winter. {T}his study aims to disentangle the effects of photoperiod and diapause on embryonic developmental time and egg size in {A}. albopictus. {A} temperate strain capable to perform diapause and a tropical strain unable of diapause were reared at 21 degrees {C} with long-({LD}) and short-day ({SD}) lengths. {F}our distinct traits were studied on embryos and eggs were measured at the end of embryogenesis. {R}esults: {T}he chronologies of embryo development for both strains were influenced by maternal photoperiod, especially in the temperate strain in which the development of {SD} eggs took longer than {LD} eggs. {T}he delay increased gradually in the temperate strain, and reached up to 38 h at the end of embryogenesis. {T}he kinetics of embryogenesis differed among the temperate and the tropical strains, each one of the 4 studied traits showing differences. {F}or example the serosal cuticle was secreted precociously in the tropical strain. {E}gg width and volume are influenced by the maternal photoperiod and the strain x photoperiod interaction. {F}or both strains, larger eggs were laid by female reared under {SD} when compared to {LD}. {C}onclusions: {T}he influence of several maternal effects was demonstrated in this study. {T}he diapause process modifies greatly the length of embryogenesis in the temperate strain, whereas the maternal photoperiod has a direct influence on egg size and embryogenesis regardless of the strain considered. {T}hese findings provide useful data on chronology of embryonic development for integrative biology studies of egg pre-diapause stages.},
