The chronic and acute toxicity of fumonisin B 1 (FB 1 ) , a mycotoxin from Fusarium moniliforme , to the larvae of the yellow mealworm, Tenebrio molitor , was assessed. The toxin was administered via the diet or injected directly into the larvae. Young T. molitor larvae fed on a diet containing 450 μg FB 1 per g diet exhibited reduced growth performance but only after consuming the fumonisin‐contaminated diet for several weeks. FB 1 ‐contaminated diet also reduced the rate of carbon dioxide production, food consumption and protein metabolism. The concentrations of FB 1 in the diet did not increase mortality, even when tested at the highest dose of 450 μg FB 1 per g of diet. Injection of 25 ng FB 1 per larva decreased the CO 2 production, but became significant only 11 days after the injection and was reversible with time. A parallel analysis of the retention of FB 1 by the larvae indicated that about 40% of the ingested FB 1 was excreted in the faeces.
