This invention relates to a new substance trehalostatin, a method of producing said substance, and an actinomycete producing said substance. Trehalostatin has the following physicochemical properties: form: white powder, solubility: soluble in water, and difficultly soluble in hexane, benzene, ether and petroleum ether, UV spectrum: no absorption maxima above 220 nm, color reaction: positive in Rydon-Smith reaction, and negative in ninhydrin reaction, 3,6-dinitrophthalate reaction and Elson-Morgan reaction, molecular weight:366 (m/z 367, M+H, according to SIMS),[α]D: +115°. Trehalostatin exhibits an inhibitory effect on insect, especially trehalose of Aldrichia grahami , even at an extremely low concentration and thus is useful as an insecticide. |
