ABSTRACT Seedlings of kale cultivars in New Zealand are highly susceptible to direct feeding by the wheat bug Nysius huttoni (Hemiptera: Lygaeidae), an endemic insect pest. Two assays (choice and no-choice) were conducted to compare the relative susceptibility of seedlings of the six most popular kale cultivars in New Zealand (Kestrel, Gruner, Sovereign, Regal, Corka and Coleor). The earliest occurrence of feeding damage in the choice assay was on cv. Kestrel, significantly earlier than on Corka and Gruner. In the no-choice assay, significantly more wheat bugs were found on Kestrel than on Corka. Damage to Kestrel occurred significantly earlier than on all the other cultivars except Corka. Reduction in plant dry weight was significantly higher on Coleor and Kestrel. These results are important for developing integrated pest management protocols for kale pests.

羽衣甘蓝品种对新西兰小麦虫 Nysius huttoni（半翅目：Lygaeidae）的敏感性

摘要 新西兰羽衣甘蓝品种的幼苗极易受到小麦虫 Nysius huttoni（半翅目：Lygaeidae）（一种地方性害虫）的直接喂养。进行了两种检测（选择和不选择）来比较新西兰六种最受欢迎​​的羽衣甘蓝品种（红隼、格鲁纳、君主、富豪、科卡和科尔）幼苗的相对易感性。选择试验中最早发生的摄食损伤是在 cv。Kestrel，明显早于 Corka 和 Gruner。在无选择试验中，在 Kestrel 上发现的小麦虫明显多于在 Corka 上。除了 Corka 之外，Kestrel 的损坏发生时间明显早于所有其他品种。Coleor 和 Kestrel 的植物干重降低显着更高。
