OBJECTIVE: To explore the effect of different temperatures on the different development stages of Aedes albopictus. METHODS: The changes at different development stages of mosquitoes (egg, larva, pupae) and gonotrophic cycle were observed at different temperature conditions of 10, 15, 20, 25, 30, 35 °C and 40 °C. The full developmental cycles were compared during different temperatures. RESULTS: All the stages of the mosquitoes could not develop at 10 °C. Under the different temperatures of 15, 20, 25, 30, 35 °C and 40 °C, the hatchabilities of the mosquitoes were 0, 32%, 82%, 83%, 82% and 59% respectively; the pupation rates of the mosquitoes were 38%, 53%, 84%, 88%, 72% and 42% respectively; and the emergence rates of the mosquitoes were 92%, 95%, 97%, 97%, 83% and 17% respectively. The mosquitoes could well develop at 20, 25, 30 °C and 35 °C, the development time was 37.73, 18.50, 16.92 and 13.66 days respectively. CONCLUSION: The development time of Aedes albopictus is shorter at the higher temperature. The optimum temperature for the mosquitoes to develop is between 25-30 °C, and higher or lower the temperatures will suppress the development of the mosquitoes.
