TY  - JOUR
AB  - Laboratory-derived temperature dependencies of life history traits are increasingly being usedto make mechanistic predictions for how climatic warming will affect vector-borne diseasedynamics, partially by affecting abundance dynamics of the vector population. Thesetemperature-trait relationships are typically estimated from juvenile populations reared onoptimal resource supply, even though natural populations of vectors are expected toexperience variation in resource supply, including intermittent resource limitation. Usinglaboratory experiments on the mosquito Aedes aegypti, a principal arbovirus vector,combined with stage-structured population modelling, we show that low-resource supply inthe juvenile life stages significantly depresses the vector’s maximal population growth rateacross the entire temperature range (22–32°C) and causes it to peak at a lower temperaturethan at high-resource supply. This effect is primarily driven by an increase in juvenilemortality and development time, combined with a decrease in adult size with temperature atlow-resource supply. Our study suggests that most projections of temperature-dependentvector abundance and disease transmission are likely to be biased because they are based ontraits measured under optimal resource supply. Our results provide compelling evidence forfuture studies to consider resource supply when predicting the effects of climate and habitatchange on vector-borne disease transmission, disease vectors and other arthropods.
