Sexual reversal of males is caused by the feminizing action of either intracytoplasmic symbiotic bacteria (F) or a less stable f factor. The inoculation of crushed ovaries of symbiotic females (ZZF neo- � ) in non-symbiotic females (ZW 9 and ZZf neo- � ) does not alter the onset of repro- duction. Growth, however, and consequently fertility, is considerably slowed down by the intro- duction of these feminizing bacteria. There is no such noticeable pathogenic effect in ZZf neo- females. These results are analyzed according to the various possible origins of the micro- organism and of the different types of females.
