Popis:	Cruciferous varieties encompassing 10 different crops were compared in the field in the Coastal Plain of North Carolina for resistance to larvae of the diamondback moth, Plutella maculipennis (Curtis). The most resistant varieties were radish, turnip, mustard, and some varieties of cabbage, kale, and collard. The most susceptible varieties were broccoli, rutabaga, brussels sprouts, cauliflower, and some varieties of cabbage, collard, and kale. Vates kale was among the most resistant crucifers and Dwarf Siberian kale was one of the most susceptible to diamondback back moth larvae. In the laboratory, newly hatched larvae were observed to enter the lower leaf epidermis and live as miners. Vates kale showed a higher antibiosis to these larvae than Dwarf Siberian kale. An examination of the leaf tissue showed Vates kale to have densely compact cells without air spaces, while Dwarf Siberian kale had loosely arranged cells and an abundance of air spaces. None of the young larvae survived on old hardened leaves of either variety.
