In this article, the biology and fertility life table parameters of the cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), were studied on cauliflower leaves, Brassica oleracea var. botrytis (Brassicales: Brassicaceae), of the cultivars Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG, and Tokita. This study was conducted under controlled conditions: 25 ± 2°C, 65 ± 5% relative humidity (RH), and 16:8 (L:D) h photoperiods. Statistical analysis showed that there was a significant difference (P < 0.05) between the different growth stages and the mean number of laid nymphs. Further, the maximum and minimum growth periods were observed on Galiblanka and Buris cultivars, respectively. The shortest nymphal instar growth period was observed on the Smilla cultivar (6.70 d), and the longest lifespan was seen on the White cloud (8.10 d). The Smilla cultivar (39%), in an adult emergence stage, and the SG (88%) revealed the lowest and highest rates of survival, respectively. Aphids reared on the Smilla cultivar were found to have increased due to the high intrinsic (r(m)) and finite (λ) rate of increase and the low doubling time (DT). The results indicated that the application of cultivars affecting adult reproductive parameters could be a good solution to cabbage aphid control management.
在本文中，研究了甘蓝蚜（Brevicoryne brassicae (L.)，半翅目：蚜科）在栽培品种斯米拉（Smilla）、雪之魅（Snow mystique）、白云（White cloud）、布里西斯（Buris）、加利布兰卡（Galiblanka）、雪冠（Snow crown）、SG和户田（Tokita）的花椰菜叶片（甘蓝变种花椰菜，十字花目：十字花科）上的生物学和繁殖力生命表参数。本研究在可控条件下进行：温度25±2°C，相对湿度65±5%，光周期16:8（光照:黑暗）小时。统计分析表明，不同生长阶段与若虫平均产卵数之间存在显著差异（P<0.05）。此外，在加利布兰卡和布里西斯品种上分别观察到最长和最短的生长期。在斯米拉品种上观察到最短的若虫龄期生长期（6.70天），在白云品种上观察到最长的寿命（8.10天）。在成虫羽化阶段，斯米拉品种（39%）和SG品种（88%）分别显示出最低和最高的存活率。发现在斯米拉品种上饲养的蚜虫由于其较高的内禀增长率（r(m)）和有限增长率（λ）以及较低的加倍时间（DT）而数量增加。结果表明，应用影响成虫繁殖参数的品种可能是控制甘蓝蚜的一个良好解决方案。
