The diverticula of the organ showed drastic increases of the volume and number according to the larval growth. Especially passing through the stage of postlarva 10, they increased rapidly more than at previous stages as from the zoea 3 to the postlarva 9. It suggested that the early larvae so far as of the postlarva 10 would suffer diseases more easily than at the later period, if the midgut gland functioned as a member of the defence mechanism during their developmental process.}, pages = {221--225}, title = {Organogenesis of the Midgut Gland in the Prawn Penaeus japonicus}, volume = {36}, year = {} }
