Abstract

New A83543 components, including fermentation products A83543K, A83543O, A83543P, A83543U, A83543V, A83543W and A83543Y and N-demethyl derivatives, and salts thereof, are useful for the control of insects and mites. The pseudoaglycones of the new A83543 components are useful for the preparation of A83543 components. Methods are provided for making the new A83543 components by culturing of Saccharopolyspora spinosa NRRL 18395, NRRL 18537, NRRL 18538, or NRRL 18539, or NRRL 18743 or NRRL 18719 or NRRL 18823 in suitable culture medium. Insecticidal and ectoparasiticidal compositions containing new A83543 components are also provided.

Claims2

Dependent claims

A method of reducing a population of insect ectoparasites which consume blood of a host animal which comprises administering to the host animal an insect-inactivating amount of a compound of the following formula:

##STR20## wherein R.sup.7 is hydrogen or a group of formula ##STR21## R.sup.8, R.sup.9, R.sup.10, R.sup.11, and R.sup.12 are independently hydrogen or methyl, provided that R.sup.11 and R.sup.12 are not concurrently hydrogen;
or an acid addition salt thereof when R.sup.7 is other than hydrogen.

Dependencies are inferred from the claim text.
