On the ceiling of the Oriental hornet comb cell, there are mineral granules of polycrystalline material known to belong to the group of perovskites. In a comb cell intended to house a worker hornet, the roof base usually carries one or several such perovskite granules containing titanium (Ti), whereas in the roof base of a cell housing a developing queen, there are usually several granules containing a high percentage of silicon (Si), aluminum (Al), calcium (Ca), and iron (Fe), but very little if any Ti. In worker comb cells, Ti usually appears as ilmenite (FeTiO3). Besides documenting the above-mentioned facts, this report discusses possible reasons for the appearance of ilmenite crystals in worker cells only and not in queen cells.
在东方大黄蜂蜂巢巢室的顶部，存在已知属于钙钛矿类的多晶材料矿物颗粒。在一个用于容纳工蜂的巢室中，顶部通常带有一个或几个这样含钛（Ti）的钙钛矿颗粒，而在一个容纳发育中蜂王的巢室顶部，通常有几个含有高比例硅（Si）、铝（Al）、钙（Ca）和铁（Fe），但钛含量极少（如果有的话）的颗粒。在工蜂巢室中，钛通常以钛铁矿（FeTiO₃）的形式出现。除了记录上述事实外，本报告还讨论了仅在工蜂巢室而非蜂王巢室中出现钛铁矿晶体的可能原因。
