A population of newly hatched DSX larvae was passed through the COPAS machine the indicated number of times and larvae of the indicated sex were requested successively. The number of larvae surviving to adulthood was scored and the sex of the resulting adults was verified. No error was found and survival was not affected by the number of passes through the machine.
