  abstract = {{B}ackground{A}edes aegypti and {A}e. albopictus are primary vectors of dengue virus in {C}ambodia, distributed throughout the country. {C}limate change is predicted to affect the relative density of these two species, but there is a lack of studies evaluating the impact of temperature on populations of these two species in this region. {T}his study investigates the impact of temperature on the survival, development and longevity of {A}e. aegypti and {A}e. albopictus from populations collected in {P}hnom {P}enh, {C}ambodia.{M}ethods{A}edes aegypti and {A}e. albopictus populations were collected in {P}hnom {P}enh. {T}he experiment was conducted in a climatic chamber with temperatures ranging from 15 degrees {C} to 40 degrees {C}, with a 5 degrees {C} increment between each treatment. {B}ionomic parameters from the {F}2 egg hatching rate to the number of {F}3 eggs produced at each temperature treatment were measured.{R}esults{T}emperature significantly influenced all life history traits of {A}e. aegypti and {A}e. albopictus. {T}he highest egg hatching rates were observed at 25 degrees {C} for {A}e. aegypti (97.97%) and 20 degrees {C} for {A}e. albopictus (90.63%). {L}arvae of both species could not survive beyond the first stage at 40 degrees {C}. {D}uring immature stages, development time decreased at higher temperature (35 degrees {C}), but mortality was increased. {F}emale longevity peaked at 25 degrees {C} for {A}e. aegypti (66.7 days) and at 20 degrees {C} for {A}e. albopictus (22.6 days), with males having significantly shorter lifespans. {I}n addition, the optimal temperature for female survival is predicted higher in {A}e. aegypti than in {A}e. albopictus, at 27.1 degrees {C} and 24.5 degrees {C}, respectively. {W}ing length increased at lower temperatures, with {A}e. aegypti consistently longer than {A}e. albopictus at 15 degrees {C} and 35 degrees {C}. {B}lood-feeding rates were highest at 30 degrees {C} for {A}e. aegypti (61.0%) and at 25 degrees {C} for {A}e. albopictus (52.5%).{C}onclusion{A}edes albopictus appears better adapted to lower temperatures, whereas {A}e. aegypti is better adapted to higher temperatures. {W}armer temperatures accelerate mosquito development but also increased mortality and reduced adult longevity, which could influence their ability to transmit pathogens. {T}hese findings highlight the critical role of temperature in mosquito biology and emphasize the potential impact of climate change on dengue transmission dynamics in the future.},
