(Fabricius) (Coleoptera: Chrysomelidae) is one of the most damaging pests affecting vegetables. This pest feeds on the leaves and roots of Brassicaceae plants during their adult and larval stages, respectively, resulting in substantial economic losses. The laboratory-rearing methods for and its life-history parameters have not been fully studied. This study developed a laboratory method for the generational rearing of , including techniques for egg collection and rearing immature individuals, which allows for the continuous observation and collection of individuals at various developmental stages. This method established five F1 populations and three consecutive generations of from various field-collected parent populations. During the rearing process, developmental durations and survival rates at four stages of were acquired, confirming the method's effectiveness. The female ratio, tibia length of the hind leg, and fluctuating asymmetry of adults in three of the five F1 populations were measured to assess 's adaptability to the rearing conditions. The established laboratory-rearing method and life-history parameters of could potentially contribute to research in its ecology, population dynamics prediction, and pest management.
（法布里丘斯）（鞘翅目：叶甲科）是危害蔬菜最严重的害虫之一。这种害虫在成虫和幼虫阶段分别取食十字花科植物的叶片和根部，造成巨大经济损失。其实验室饲养方法及其生活史参数尚未得到充分研究。本研究开发了一种实验室世代饲养方法，包括卵收集和未成熟个体饲养技术，可对不同发育阶段的个体进行连续观察和收集。该方法从不同田间采集的亲代种群中建立了五个F1种群和三代连续的（法布里丘斯）。在饲养过程中，获得了（法布里丘斯）四个阶段的发育历期和存活率，证实了该方法的有效性。测量了五个F1种群中三个种群成虫的雌虫比例、后腿胫节长度和波动不对称性，以评估（法布里丘斯）对饲养条件的适应性。所建立的实验室饲养方法和（法布里丘斯）的生活史参数可能有助于其生态学、种群动态预测和害虫管理方面的研究。
