摘要
The insecticidal strain 173 was isolated from marine source and its activity was explored by the bioassay of brine shrimp and Helicoverpa armigera . Based on morphological, physiological and molecular properties, the insecticidal strain 173 was identified as Streptomycetes avermitilis , which is the best insecticidal microorganism found in the terrestrial environment. The taxonomy of the strain 173, insecticidal spectrum and properties of the corresponding insecticidal antibiotics are reported.
