蜜蜂（Apis mellifera）的磁场感受性表现为筑巢和归巢定向等活动，这些活动受地磁场的影响。在其他磁感受物种中，磁铁矿形式的氧化铁晶体已被证明是磁场初级检测所必需的。在这里，它表明，滋养细胞，这显然是唯一的铁颗粒在蜜蜂细胞，含有超顺磁性磁铁矿。这些细胞受神经系统支配，这表明滋养细胞可能主要负责磁感受。电子显微镜也显示细胞骨架附着在铁颗粒膜上。
Magnetoreception by honeybees (Apis mellifera) is demonstrated by such activities as comb building and homing orientation, which are affected by the geomagnetic field. In other magnetoreceptive species, iron oxide crystals in the form of magnetite have been shown to be necessary for primary detection of magnetic fields. Here it is shown that trophocytes, which are apparently the only iron granule-containing cells in honeybees, contain superparamagnetic magnetite. These cells are innervated by the nervous system, which suggests that trophocytes might be primarily responsible for magnetoreception. Electron microscopy also shows cytoskeletal attachments to the iron granule membrane.
