The antiinsectan properties of the Fusarium graminearum ‐derived novel sterol sulfate, 4, 4, 24‐trimethylcholesta‐8, 14, 24(28)‐trien‐2α, 3β, 11α, 12β‐tetrol 12 acetate, 3‐sulfate were tested on the corn ear‐worm ( Heliothis zea (Boddie), the fall armyworm ( Spodoptera frugiperda (J. E. Smith), and the driedfruit beetle ( Carpophilus hemipterus L.). The sterol sulfate could not be used as a sterol source by any of the insects. The sterol sulfate inhibited growth of S. frugiperda and C. hemipterus larvae at 2500 and 4000 ppm, respectively. Defensive implications of this compound are discussed.
