We investigated how constant temperatures of 22, 24, and 26 degreesC experienced across the full life cycle affected the dynamics of caged populations of Aedes albopictus (Skuse). All cages were equipped with plastic beakers that served as sites for oviposition and larval development. We measured the per capita daily mortality and emergence rates of the adults and size of adult females, and estimated the intrinsic rate of increase (r) and asymptotic density (K) for each adult population. populations at 26 degreesC had greater intrinsic rates of increase and lower asymptotic densities than populations at 22 and 24 degreesC. Populations at high temperatures initially had greater daily. per capita emergence rates, and steeper. declines in per capita emergence rate as density increased over tire course of the experiment, There was no temperature effect on the size of adult females nor on the per capita daily mortality rate of adults. Results indicated that populations of Ae. albopictus occurring in regions with relatively high summer temperatures are likely to have hiyh rates of population growth with populations of adults peaking early in the season. These populations mn)l attain relatively. low peak densities of adults. Populations occurring in regions with low summer temperatures are likely to experience slow, steady production of adults throughout the season with population size peaking later in the season, and may attain higher peal, densities of adults. Nigh temperature conditions, associated with climate change, may increase the rate of spread of Ae, albopictus by increasing rates of increase and by. enhancing colonization due to rapid population growth.
