A preparation of citrinin from an isolate of Penicillium citrinum disrupted the spiracle control mechanism of the cockroach, resulting in excessive evaporation of water. The insect rapidly lost body weight and died due to dehydration within 48 h of treatment with citrinin. Presumptive evidence is given here for the neurotoxic nature of the mycotoxin.
