摘要通过对野外采集和室内孵化的圆腹Sitona discoideus Gyllenhal幼虫头囊宽度的分析，确定该种幼虫有5个龄期。概率分析允许更准确的统计定义的头胶囊大小范围内的每个特定的龄期，尽管连续龄期之间的大小重叠。
Abstract Analysis of head-capsule widths of field-collected and laboratory-hatched Sitona discoideus Gyllenhal larvae confirmed that this species possesses five larval instars. Probit analysis allowed for more accurate statistical definition of the head-capsule size ranges of each particular instar, despite size overlap between successive instars.
