Three strains of Aedes aegypti and 3 strains of Ae. albopictus of laboratory colonies were reared in different temperatures to compare their development in the immature stage (larval and pupal periods). The duration of developmental times of Ae. aegypti strains averaged 31.0-32.0 days at 15℃, 13.9-16.6 days at 20℃, 10.2-11.8 days at 25℃ and 7.4-8.2 days at 30℃. The developmental zero was 8.2-10.6℃ and the effective cumulative temperature was 145-176 days degree. For Ae. albopictus the duration of developmental times averaged 12.6-15.1 days at 20℃, 10.0-11.7 days at 25℃ and 7.6-8.4 days at 30℃. The developmental zero was 4.2-8.2℃ and the effective cumulative temperature was 166-214 days degree. Male adults emerged 0.2-1.0 days faster than females due to a difference in the duration of the 4th-instar larval period. Aedes aegypti that easily breeds in urban environment could be re-established if introduced in Japan.
