目前还没有关于竹子钻孔虫的性别鉴定的现有文献。在这项研究中，为了区分这种特殊物种的性别，研究了小黄龙成虫和幼虫的发育阶段。在体视显微镜下观察了刚杀净的成虫和幼虫的体视显微镜，并比较了这两个阶段的不同特征。结果表明，在成虫期没有明显的形态特征可用来区分性别特征。然而，在蛹阶段观察到了分化的性特征。雌蛹腹部末端有一对圆锥形突起，雄蛹则有一对附着体。这些形态特征仅在蛹阶段鉴定，证明是最可靠的性别鉴定方法。
There is no available documented literature on sexual identification of the bamboo borer Dinoderus minutus (Fabricius). In this study, adult and pupal stages of Dinoderus minutus were examined in an attempt to differentiate the sexes for this particular species. Freshly killed and cleaned adult as well as pupal stages were examined under stereomicroscopy and different characteristics for both stages were compared. Results showed that there were no distinct morphological features in the adult stage that could be used as distinguishing sexual characters. However, differentiating sexual features were observed in the pupal stage. Gonapophyses, comprising of a pair of conical extrusions were present at the terminal abdominal segment in the female pupa whilst a pair of parameres was observed in the male. These morphological characteristics which were identified only in the pupal stage, proved to be the most reliable method to determine the sex of D. minutus.
