铃木果蝇（Drosophila suzukii（Matsumura））（双翅目：果蝇科）是一种起源于亚洲的水果害虫，于2008年入侵北美。尽管该物种的广泛经济影响，但这种害虫的大部分生物学和一般生活史仍然在很大程度上未知。在最佳实验室条件下（22 ℃，相对湿度约25%），我们测量了北美D.铃木。生活史性状被用来构建生命表和繁殖表，并计算种群的内禀增长率。平均（+/- SE）总寿命（卵至成虫死亡）为86.1 +/- 4.25 d，最大值为153.7 d。平均而言，雌性每天产生5.7 +/- 0.24个卵，平均一生总产量为635.6个卵。雌虫的毛生殖率为317.8粒，净生殖率为240.4粒。内禀自然增长率为0.179。稳定的年龄分布（c（x））包括51%的幼虫，25%的卵，16%的蛹，和8%的成虫。随着时间的推移，性别比例接近1：1。我们的结论与我们的数据与以前的工作D。suzukii和其他果蝇，并讨论了控制和监测这种害虫的影响。
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a fruit pest of Asian origin that invaded North America in 2008. Despite the widespread economic impact of this species, much of the biology and general life history of this pest remains largely unknown. Under optimal laboratory conditions (22 degrees C, approximate to 25% relative humidity), wemeasured development, survival, fecundity, hatch rate, and sex ratio of a North American ecotype of D. suzukii. Life history traits were used to construct a life table and reproductive schedule, and to calculate the intrinsic rate of population increase. The mean (+/- SE) total lifespan (egg to adult mortality) was 86.1 +/- 4.25 d, with a maximum value of 153.7 d. On average, females produced 5.7 +/- 0.24 eggs per day, with a mean total lifetime production of 635.6 eggs. The gross reproductive rate was 317.8 daughter eggs per female and the net reproductive rate was 240.4 daughter eggs per female. The intrinsic rate of natural increase was 0.179. The stable age distribution (c(x)) was comprised of 51% larvae, 25% eggs, 16% pupae, and 8% adults. The sex ratio over time was approximate to 1:1. We conclude with a comparison of our data with previous work on D. suzukii and other Drosophila, and discuss the implications for control and monitoring of this pest.
