• The hormonal regulation of spermiogenesis of the common armyworm, Leucania separata, was investigated in vivo and in vitro. Elongated spermatocysts were observed on the 3rd day after the last larval ecdysis. Spermatocysts from larvae that have been ligatured between the thorax and abdomen on day 0 showed elongated spermatocysts 4 days after ligature. When testes were removed from day 2 larvae and cultured for 1 day in vitro, elongated spermatocysts were observed; the critical period for their appearance was day 2 stage. These results indicated that spermiogenesis in this species was induced without any stimulating factors such as brain hormone or ecdysone from the head or thorax. Spermiogenesis suppressed by azadirachtin is also discussed.
