Abstract:
Objective To screen 18 endophytes from Pseudolarix kaempferi Gord for molluscicidal effect and identify them by morphology. Methods Molluscicidal tests were performed according to the immersion test suggested by WHO and the strain screened was identified by the slide culture. Results The mortality rates of snails immersed by JJ18 broth salified (pH=7) were 26.7%, 76.7% and 100.0% for 24,48 h and 72 h, respectively, and 53.3% and 86.7% in 5% and 10% concentrations of JJ18 broth, respectively. The active components were extracellular moiety of the broth which had no acute toxicity to fish, and JJ18 strain belonged to Aspergillus. Conclusion Extracellular moiety of endophyte JJ18 from Pseudolarix kaempferi Gord is a new resource of molluscicide.
