不同温度下白纹伊蚊发育情况的观察

目的 目的 观察不同温度下白纹伊蚊各虫期的发育情况。方法 方法 在温度为10、 15、 20、 25、 30、 35 ℃和40 ℃的条件下， 观察实验室饲养的白纹伊蚊卵期、 幼虫、 蛹期和生殖营养周期变化情况， 比较不同温度下全发育时期之间的区别。结 结果 果 白纹伊蚊在10 ℃时各虫期均不能发育； 在15、 20、 25、 30、 35 ℃和40 ℃下其孵化率分别为0、 32%、 82%、 83%、 82%和59%； 蛹化率分别为38%、 53%、 84%、 88%、 72%和42%； 羽化率分别为92%、 95%、 97%、 97%、 83%和17%； 在20、 25、 30 ℃和35 ℃下全代发育时间分别为37.73、 18.50、 16.92 d和13.66 d。结论 结论 白纹伊蚊的发育周期随着温度升高而缩短， 最适宜发育温度为25 ~ 30 ℃， 温度过高和过低均对蚊虫发育起到抑制作用。

Effect of different temperatures on development of Aedes albopictus

Objective Objective To explore the effect of different temperatures on the different development stages of Aedes albopic?tus. Methods Methods The changes at different development stages of mosquitoes（egg，larva，pupae）and gonotrophic cycle were ob?served at different temperature conditions of 10，15，20，25，30，35 ℃ and 40 ℃. The full developmental cycles were com?pared during different temperatures. Results Results All the stages of the mosquitoes could not develop at 10 ℃. Under the differenttemperatures of 15，20，25，30，35 ℃ and 40 ℃，the hatchabilities of the mosquitoes were 0，32%，82%，83%，82% and59% respectively； the pupation rates of the mosquitoes were 38%，53%，84%，88%，72% and 42% respectively； and the emer?gence rates of the mosquitoes were 92%，95%，97%，97%，83% and 17% respectively. The mosquitoes could well develop at20，25，30 ℃ and 35 ℃，the development time was 37.73，18.50，16.92 and 13.66 days respectively. Conclusion Conclusion The devel?opment time of Aedes albopictus is shorter at the higher temperature. The optimum temperature for the mosquitoes to develop isbetween 25-30 ℃， and higher or lower the temperatures will suppress the development of the mosquitoes.
