摘　　要：目的比较白纹伊蚊溴氰菊酯抗性品系和敏感品系的生物学特性及种群变化。方法实验室内观察2个蚊虫品系的繁殖、发育、吸血等生物学特性,构建实验种群生命表。结果白纹伊蚊抗溴氰菊酯品系的孵化率、蛹化率以及羽化率分别比敏感品系低16.67%、8.92%和0.44%,除羽化率外,上述指标两者之间差异均有统计学意义(P<0.05)。抗性品系的吸血率及单雌产雌数均比敏感品系低。前者的净增值率和内禀增殖率分别为151.86和0.16,后者的净增殖率和内禀增值率分别为177.18和0.20。结论白纹伊蚊抗性品系已表现出环境适应能力下降和繁殖不利性的影响。Objective To compare biological characteristics and population dynamics of dehamethirn-resistance strain and susceptible strain of Aedes albopictus in the laboratory. Methods Biological characteristics of two mosquito strains such as reproduction, development and bloodsucking were observed and recorded in the laboratory, and the life tables of them were established. Results The hatching rate, pupation rate and emergence rate of resistance strain were lower than that of susceptible strains, decreasing about 16.67%, 8.92%, and 0.44% respectively, and the difference of them were significant （P〈0.05）. The bloodsucking rate and the quantity of female filial generation reproduced by each female of resistance strain were also lower than that of susceptible strain. R0 and r. of resistance strain were 151.86 and 0.16 respectively, however that of susceptible strain were 177.18 and 0.20. Conclusion The resistance of Ae.albopictus to deltamethrin results in the decrease of adaptability to environment change and the disadvantage of reproduction.
