  • Paralysis is defined as the condition in which the animal lies on its back with little movement of the wings and legs. The temperature of paralysis is assessed by the occurrence of paralysis within 2 min at a specific temperature. Wild-type flies (ORR) are incapacitated at 42°; however, this behavior cannot be confused with the typical features of shi paralysis, which is preceded by characteristic behavioral seizures and uncontrolled wing-beating.
