Abstract
Fermentation product A83543, comprising major components A83543A and A83543D and minor components A83543B, A83543C, A83543E, A983543F, A83543G, A83543H and A83543J, is produced by a newly described species, Saccharopolyspora spinosa. The A83543 components and their acid-addition salts (A83543 compounds) are useful as insecticides, particularly against Lepidoptera and Diptera species. Insecticidal, miticidal or ecto-parasiticidal combinations, compositions and methods are provided.

A process for producing fermentation product A83543, comprising A83543A, A83543B, A83543C, A83543D, A83543E, A83543F, A83543G, A83543H, and A83543J which comprises cultivating a Saccharopolyspora spinosa strain selected from NRRL 18395, NRRL 18537, NRRL 18538 or NRRL 18539, or an A83543-producing strain derived therefrom, in a culture medium containing assimilable sources of carbon, nitrogen, and inorganic salts under submerged aerobic fermentation conditions until a recoverable amount of A83543 is produced.
A biologically purified culture of Saccharopolyspora spinosa selected from NRRL 18395, NRRL 18537, NRRL 18538, or NRRL 18539, or an A83543-producing strain derived therefrom.
