BIOTHUR is an aerobic, gram-positive, bacillus found naturally in soil and plants.
It was discovered in Japan in 1902 by Ishiwata and a few years later was isolated in Thuringen (Germany).
It was first sold in France, in 1938, and is now the most widely used biopreperation. Its larvicidal action varies depending on the chosen strain; the variety kurstaki, serotype 3a3b, has an action against Lepidoptera.
