Abstract:Effects of parathion intoxication on gut functions of the Madeira cockroach, Leucophaea maderae (F.), were studied in vivo with X-ray techniques. The foregut accumulated large volumes of air and sometimes fluid during the prostration and paralysis stage of poisoning. Rapid rebloating occurred in these insects when the initial gas contents were removed with a syringe. Carbon dioxide accumulated in the foregut while oxygen decreased during the time of bloating. This condition appears to be a secondary effect of prolonged intoxication by parathion as well as a number of other nerve poisons, resulting from the uncontrolled entry of air into the foregut. Sphincter valve operation and peristaltic contractions of the gut continued after the somatic muscles became paralyzed, as was evidenced by the movement of barium sulfate throughout the alimentary canal in prostrate cockroaches.
