目的:实验室条件下比较不同温度对白纹伊蚊氯氰菊酯抗性品系和敏感品系生物学特性的影响和差异。方法选择20、25℃和28℃3个不同温度条件下饲养的白纹伊蚊氯氰菊酯敏感和抗性品系,观察2个品系的繁殖、发育及平均寿命等生物学特性,并对结果进行统计分析。结果25℃下抗性品系卵的孵化率(69.37%±0.01%)和化蛹率(77.04%±0.07%)显著低于敏感品系(孵化率和化蛹率分别为85.24%±0.03%和88.23%±0.05%),分别下降了25.88%和11.18%;在实验温度下各品系成蚊预期寿命随温度增加而缩短,敏感品系在28、25℃和20℃下历期分别为19.75±0.10、23.65±0.07 d和25.08±0.08 d,而抗性品系在上述3种温度下则分别降为17.21±0.09、20.95±0.09 d和22.58±0.10 d;同时,抗性品系成蚊平均寿命低于敏感品系;同一实验温度下抗性品系幼虫发育周期较敏感品系延长,28℃下差异最大,抗性品系和敏感品系分别为156.2 h和137.1 h;不同品系幼虫发育历期随温度升高而缩短,28、25℃和20℃下敏感品系和抗性品系幼虫发育历期分别为137.1、163.3、247.7 d和156.2、182.3、263.2 d,上述指标两者之间差异均有统计学意义(P均<0.05)。结论不同温度下,白纹伊蚊抗氯氰菊酯品系环境适应能力和生殖力水平均低于敏感品系。

Objective To study the biological characteristics of cypermethrin?resistance strain and?susceptible strain of Ae?des albopictus under different controlled temperatures in the laboratory. Methods The two strains were raised at three different temperatures 20 25℃and 28℃respectively and the biological characteristics of the two mosquito strains such as reproduc?tion development and life expectancy were observed and recorded in the laboratory. Results The life expectancy of both strains became shorter as the temperature raised and the resistant strain 69.37%± 0.01% 77.04%± 0.07% lived shorter than the susceptible strain 85.24%±0.03% 88.23%±0.05% in average. Under 25℃ the hatching rate of resistant strain decreased by 25.88% and the pupation rate decreased by 11.18%. In the three temperatures all the life expectancy expanded as the tem?perature went up the periods for the susceptible strain were 19.75±0.10 23.65±0.07 d and 25.08±0.08 d under 28 25℃and 20℃. While life expectancy for the resistant strain decreased to 17.21±0.09 20.95±0.09 22.58±0.10 d. Under the same tem?perature the development timing of the resistance strain was longer than that of the susceptible strain and the period was the longest under 28 ℃ 156.2 h 137.1 h . In the three temperatures all the development periods expanded as the temperature went up the susceptible and resistant larvae developed 137.1 d and 163.3 d 247.7 d and 156.2 d 182.3 d and 263.2 d under 28 25℃and 20℃. The differences show statistic significance P<0.05 . Conclusion The resistance of A. albopictus to cy?permethrin results in the decrease of adaptability to the environment change and the disadvantage of reproduction at different temperatures.
