摘要
An aphicidal metabolite produced by Bacillus amyloliquefaciens G1 was isolated, and its activity was examined against green peach aphid (Myzus persicae). Bioassay-guided column chromatography followed by instrumental analyses identified surfactin as a major metabolite, showing LC50 value of 35.82 mu g/mL. This is the first report of surfactin as an insecticidal metabolite against Myzus persicae.
