| 中文摘要: |
| 为了明确温度对韭菜迟眼蕈蚊生长发育和繁殖的影响, 本文利用年龄-阶段两性种群生命表研究了该虫北京种群在4种温度(15、20、25和30℃)下的发育历期、存活率、繁殖力以及其他的种群参数。结果表明, 韭菜迟眼蕈蚊各虫态发育历期以及产卵前期均随温度升高而缩短。在25℃条件下的单雌产卵量为85.34粒, 显著高于其他3个温度。内禀增长率(r)和周限增长率(λ)随温度的升高而升高, 平均世代周期(T)则出现相反的趋势, 在25℃下净增殖率(R0)最大, 为45.77。韭菜迟眼蕈蚊在15~30℃范围内都能完成生长发育和繁殖, 但25℃下种群存活率高、繁殖力大、世代周期较短, 更适合种群暴发。 |
| 英文摘要: |
| In order to understand the effects of temperature on Bradysia odoriphaga Yang et Zhang, the age-stage two-sex life table was used to obtain the developmental duration, survival rate, fecundity and population parameters of Beijing population under four different temperatures (15, 20, 25 and 30℃). The results showed that the developmental duration and pre-oviposition duration of B. odoriphaga decreased with increasing temperature. The average number of eggs laid per female at 25℃ was 85.34, significantly higher than at the other three temperatures. The intrinsic rate of increase (r) and the finite rate of increase (λ) increased with increasing temperature; however, the mean generation time (T) had a different trend. The highest net reproductive value (R0) occurred at 25℃ (45.77), significantly different from those at the other temperatures. These results indicated that B. odoriphaga was able to develop, survive and reproduce successfully across the entire temperature range from 15℃ to 30℃; however, under the condition of 25℃, with higher survival rate and fecundity and shorter generation, it was the most suitable temperature for the population growth of B. odoriphaga. |
