The adult antennae of the eri-silkworm, Samia cynthia ricini, are prominently bipectinate in both sexes. When β-ecdysone was injected into 4 hour old male pupae of the eri-silkworm at the relatively high dosage of 20μg/g body weight abnormal antenna development was induced. The resulting antennae were missing barbs on all segments of the flagella. The first manifestation of morphological abnormality was the cessation of cuticle deposition on the pupal antennal sheath and the high frequency of cell death in the area of barb formation. This was followed by a chaotic arrangement of the epidermal cells. Histological observations revealed that excessive β-ecdysone accelerates the death of larval cells in the early pupal stage, and impedes the full development of the cells destined to form barbs and other structures of the adult antennae.
