Abstract: Objective To observe the effect of clarified lime water on Aedes albopictus at different stages of larval development in the laboratory and determine the effect of quicklime in the prevention and control of Ae. albopictus, and to provide basic data for the application of quicklime in the prevention and control of Ae. albopictus. Methods A certain number of Ae. albopictus at different developmental stages (eggs, 1 st to 4 th instar larvae, and pupae) were separately reared in clarified lime water, and the hatching rate, mortality rate, eclosion rate, and development time for each stage were recorded. Meanwhile, the development of Ae. albopictus in different feeding environments and different stages was analyzed and compared by taking the mosquitoes reared in overnight tap water as a control. Results The hatching rate of Ae. albopictus eggs in the experimental group was 82.22%, and that in the control group was 94.44%; the hatching rate of Ae. albopictus eggs was significantly lower in the experimental group than in the control group (χ2=6.523, P=0.011). According to the t-test, the hatching time of eggs was significantly longer in the experimental group than in the control group. The mortality rate of the 1st to 4th instar larvae was significantly higher in the experimental group than in the control group (χ2=4.624, 234.994, and 284.312, P=0.032, <0.003, and <0.003); particularly, the mortality rate of the 3rd and 4th instar larvae was significantly increased in the experimental group. There was no significant difference in eclosion rate between the experimental group and the control group (χ2=0.593, P=0.441). Conclusion Clarified lime water has a significant inhibitory effect on the development of Ae. albopictus, which increases with the age of mosquito larvae. The results imply that quicklime can be possibly used for the prevention and control of Ae. albopictus. The field control effect of quicklime on Ae. albopictus needs further verification.

摘要: 目的 于实验室观察澄清石灰水对白纹伊蚊生活史幼期不同阶段的影响,用于确定生石灰对防制白纹伊蚊的效果,为生石灰用于现场白纹伊蚊防治提供参考数据。方法 将一定数量的白纹伊蚊依据不同发育阶段(卵、1~4龄期幼虫、蛹)分别饲养于澄清石灰水中,记录不同时期相应孵化率、死亡率、羽化率和发育时间,同时将实验室过夜自来水饲养蚊虫作对照,分析比较不同饲养环境、不同发育阶段白纹伊蚊的变化差异。结果 实验组白纹伊蚊卵的孵化率为82.22%,对照组为94.44%,经χ2检验,实验组白纹伊蚊卵孵化率显著低于对照组(χ2=6.523,P=0.011),经t检验,卵的孵化时间明显滞后;实验组1~4龄幼虫的死亡率高于对照组(χ2=4.624、234.994、284.312,P=0.032、<0.003、<0.003),特别是3、4龄幼虫的死亡率显著升高,而实验组蛹期的羽化率与对照组比较差异无统计学意义(χ2=0.593,P=0.441)。结论 澄清石灰水对白纹伊蚊发育具有明显抑制作用,且随着幼蚊年龄的增长其抑制效果更加显著;实验室结果提示生石灰用于白纹伊蚊防治的可能性,有待现场实验进一步验证。
