摘要

An actinomycete strain KN-0647 was isolated from a forest soil sample collected from Dali Cangshan mountain, Yunnan Province, China. The strain was identified as Streptomyces sp. according to the morphological, physiological characteristics and whole nucleotide sequence analysis of 16S rRNA gene, and could not be identified up to species level, just suggesting a potential new taxon. The ethyl acetate extract from this strain displayed growth inhibition on the test pathogenetic insects, such as Spodoptera exigua, Dendrolimus punctatus, Plutella xylostella, Aphis glycines and Culex pipiens. The active compound was isolated and identified through a combination of spectral and chemical methods (UR, MS, and 1HNMR) as quinomycin A. This is the first report on the insecticidal activity of antibiotic quinomycin A.
