          Abstract

          Objective To understand the effective temperature for whole generation development of mosquitoes, thus to provide theory evidence for vector control. The development and reproductive conditions of Aedes albopictus, Culex pipiens pallens and Anopheles sinensis under different temperatures were observed in this study.

          Methods The vegetative reproductive cycle, egg, larvae and pupae stages and gonotrophic cycler of Aedes albopictus, Culex pipiens pallens and Anopheles sinensis at 7 different temperatures, as 10, 15, 20, 25, 30, 35, 40 °C with illumination incubation were observed in 2017.

          Results Among 7 groups, the Aedes albopictus and Anopheles sinensis couldn’t complete the full developmental cycler at 10 °C, 15 °C and 40 °C, the temperature of the other 4 groups could complete the whole generation development. The average developmental time for Aedes albopictus and Anopheles sinensis were 37.73 d, 18.50 d, 16.92 d, 13.66 d and 29.13 d, 15.46 d, 12.19 d, 10.90 d respectively at 20 °C, 25 °C, 30 °C, 35 °C. Culex pipiens pallens couldn't complete the full developmental cycler at 40 °C, the temperature of the other 6 groups could complete the whole generation development. The average developmental time for Culex pipiens pallens were 80.88, 46.32, 31.07, 24.97, 17.14 and 14.48 d respectively at other 6 temperature.

          Conclusion The cyclogeny time decreased with high temperatures. The mosquitoes cannot complete the full developmental stages under excessive low or high temperatures. The temperature has different effect on the 3 species mosquitoes.

          Abstract

          摘要: 目的 观察白纹伊蚊、淡色库蚊和中华按蚊等3种江苏省主要传病媒介在不同温度条件下各虫期发育与繁 殖情况, 了解蚊虫完成全代发育的有效温度, 为制定或实时调整蚊虫防制措施提供理论依据。 方法 2017年用光照培 养箱饲养法, 设置10、15、20、25、30、35和40 ℃等7组不同温度, 分别观察实验室饲养的白纹伊蚊、淡色库蚊和中华按蚊 生殖营养周期、卵期、幼虫和蛹期的发育繁殖和全发育时期情况。 结果 在7组温度中, 白纹伊蚊和中华按蚊在10、15 和40 ℃时不能完成蚊虫全代发育, 其余4组温度均能完成全代发育, 其中在20、25、30和35 ℃时白纹伊蚊的平均发育 时间分别为37.73、18.50、16.92和13.66 d, 中华按蚊的平均发育时间分别为29.13、15.46、12.19和10.90 d; 淡色库蚊除 40 ℃不能完成全代发育外, 其余6组温度均能完成全代发育, 按照温度递增顺序平均时间分别为80.88、46.32、31.07、 24.97、17.14和14.48 d。 结论 一定温度范围内, 蚊虫的发育周期随着温度升高而缩短, 温度过高和过低均对蚊虫发育 繁殖起到损害作用; 温度对3种蚊虫的发育与繁殖影响有所区别。
