Fig 6. Effect of ingestion of harman and norharman with the diet on adult molt of Galleria mellonella pupae.

1H- harman 750 ppm, 2H- harman 1000 ppm, 3H- harman 1250 ppm. 1N- norharman 750 ppm, 2N- norharman 1000 ppm, 3N- norharman 1250 ppm. Insects received alkaloids on the third day of the final larval instar. In control groups, all pupae became adults. In the 1H, 2H, 3H, 1N, 2N and 3N groups, respectively, 90%, 90%, 80%, 90%, 90% and 75% of pupae became adults.
