title: Microbial metabolites with insecticidal properties.
abstract: A screen of fungi for insecticidal activity revealed the ability of Aspergillus versicolor to make versimide, methyl-alpha-(methylsuccinimido)acrylate, a novel contact insecticide. The larvicidal activities of Alternaria tenuis and Fusarium lateritium were found to be due to tenuazonic acid and diacetoxyscirpenol, respectively. Thiolutin, cycloheximide, rubratoxin, patulin, trichothecin, an actinomycin, and scirpene-producing fungi also had insecticidal activity.
