摘要: It is widely documented that in Bonellia viridis Rolando (Echiura), the larvae settle on proboscis of adult female and differentiate into males. This study shows although settlement preferred, can also body trunk Aqueous extracts homogenized tissues are as effective those masculinizing larvae. The natural secretion trunk, which produced when worm disturbed, has potent properties. preferential probiscis may not result from a different chemical nature substratum.
