[Advances in researches of biogenic molluscicides]

Biogenic molluscicides refer to the use of plants, animals and micro-organisms or their metabolites, and synthesis biomimetic molluscicides to kill Oncomelania hupensis snails. With the rapid development of science and technology, new biogenic molluscicides are continuously emerging and the category also continues to expand. According to the molluscicidal active ingredient and sources, at present, the biogenic molluscicides with in-depth studies include plant-derived molluscicides, micro-organism molluscicides, microbial metabolite molluscicides and animal molluscicides. This paper reviews the advances in the researches of biogenic molluscicides in recent years.
