【摘要】 在实验室条件下观察白纹伊蚊种群发育、存活和繁殖的动态,得出年龄特征存活率、繁殖率等数据,编制成生命表,计算出有关种群各项参数,包括内禀增长能力（r_m=0.1333）,净增殖率（R₀=45.3017）,增殖有限速率（λ=1.1426）,平均世代周期长（T=33.3299天）,瞬时出生率和死亡率（b=0.5562,d=0.4229）,稳定年龄组配,成虫前期占90.66％,成虫期占9.34％。该蚊种群大约每隔5.2天增加一倍。根据结果对该蚊种群传播登革热的关系和防制加以讨论。更多还原

【Abstract】 A laboratory experiment on Aedes (Stegomyia) albopictus (Skuse) was carried out to look for the information of mortality and fecundity and to derive statistical estimation of some population parameters. The rearing conditions were maintained at 26° ± 1℃, 60-90% RH and a light regime of 14L:10D. Data are provided for the rates of development in different stages, the percentages of survival, reproductive capacity and the sex ratio. Life expectancy is calculated for bath sexes. The following parameters have been obtained: innate capacity of population increase (rm=0.1338), instantaneous rates of birth and death (b=0.5562, d=0.4429), net reproductive, rate (R0=45.3017), finite rate of increase (A=1.1426/day), generation time (T=33.3299 days). Stable age distribution gives indication that about 90% of the population is included between the egg stage, and the beginning of the adult life. The population of this mosquito under this condition would increase by one fold in about 5.2 days. These results are discussed in the context of Dengue fever transmission.更多还原
