Datana ministra larvae possess a gland situated in the ventral anterior portion of the prothorax. The gland consists of a single sac and is only charged with secretion in the last instar. Its orifice, a simple slit, opens into a transverse invagination of the integument in the cervical margin of the prosternite. The components of the gland have been identified by GC and GCMS and have been shown to be dodecanol, dodecyl acetate, and dodecyl formate. The morphology of the gland and the chemistry of the secretion are discussed in relation to other notodontid larvae which have been investigated. It is conjectured that the secretion is not defensive in nature but may function as a dispersal pheromone.
达塔那幼虫拥有一个位于前胸腹前部的腺体。该腺体由一个单一的囊组成,仅在最后一龄时充满分泌物。它的开口是一个简单的裂缝,通向前胸腹板颈缘表皮的横凹入处。通过 GC 和 GCMS 鉴定了腺体的成分,证实其为十二醇、乙酸十二酯和甲酸十二酯。讨论了该腺体的形态和分泌物的化学性质与其他已研究过的 Notodontid 幼虫的关系。据推测,该分泌物不是防御性的,而可能作为一种扩散信息素起作用。
