Reproduction and development of Ferrissia rivularis (Say) (Basommatophora: Ancylidae) and the effects of maleic hydrazide on its development and fecundity

Kang, Yuan-Hsu 01 April 1973 (has links)
Ferrissia rivularis was selected for research because of its local accessibility and because essentially nothing was known of its reproduction and development. Reproductive and developmental biology is first described herein from the natural environment. This is then compared with the effects created by experimental exposure to a selected herbicide, maleic hydrazide, which might be a potential threat to certain invertebrates in the natural environment.
