摘要

The genus Brassica, particularly Chinese cabbage (Brassica rapa L.), play an important role in global agriculture and Asian cuisine, particularly in Korean dishes such as kimchi. Despite its nutritional benefits and popularity, Chinese cabbage cultivation faces challenges from the diamondback moth (DBM, Plutella xylostella L.), a pest notorious for causing extensive damage and showing resistance to conventional insecticides. The aim of this study is to evaluate resistance to DBM in different cultivars of Chinese cabbage using the clip-cage assay. We also measured glucosinolate (GSL) levels in the cultivars to examine the variation in specific GSL profiles associated with DBM resistance. This analysis may help identify key compounds essential for developing pest-resistant cultivars. Our findings suggest potential resistance cultivars for breeding program, contributing to sustainable agricultural practices and food security. In addition, this study supports the wider use of clip-cage assays for advancing integrated pest management strategies in plant-pest interactions.
