甘蓝蚜是危害十字花科植物的重要害虫之一，寄主范围广。本研究以Smilla、Snow mystique、白色云、Buris、Galiblanka、Snow crown、SG和Tokita等8个花椰菜品种为材料，对菜蚜的生物学参数进行了研究。本研究在受控条件下进行（25 +/- 2 ℃，65 +/-5%RH和L-D：16-8）。统计分析表明，不同生长时期和平均产卵若虫数存在显著差异（p < 0.05），因此品种Galyblanka和Buris分别出现最大和最小生长期。若虫总龄平均寿命在白色云上最长，在Smilla上最短。Galiblanka的最高若虫前期、若虫生产期、平均产卵量、成虫寿命和总寿命分别为8.60、13.50、58.60、17.30和25.90。结果表明，选用影响甘蓝蚜成虫生殖参数的品种，为降低其生殖提供条件，是解决甘蓝蚜防治的一个较好途径。
The cabbage aphid, Brevicoryne brassicae is one of the most important pests with broad host range that does damage to cruciferae plants. In this research, biology parameters of the cabbage aphid was studied on the eight cauliflower cultivars: Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG and Tokita. This study was conducted under controlled conditions (25 +/- 2 degrees C, 65 +/- 5% RH and L-D: 16-8). Statistical analysis showed that there is significant difference between different stages of growth and mean number of laid nymphs period (p < 0.05), so that the maximum and minimum growth period were observed on the cultivars Galyblanka and Buris, respectively. The longest mean longevity of total nymphal instars was obtained on White cloud, and the shortest on Smilla. The highest pre nymph period, nymph production period, mean number of laid nymphs, Adult longevity and total lifespan on the Galiblanka cultivar was calculated as 8.60, 13.50, 58.60, 17.30 and 25.90, respectively. The results showed that using cultivars that affected on the adult reproductive parameters and provides conditions for reduction of reproduction could be a good solution for the cabbage aphid control management.
