Abstract

One female of Harmonia axyridis PALLAS was found to yield the female progeny exclusively. This abnormal sex ratio was inherited maternally through 5 generations when the beetles were reared on pulverized drone honeybee brood. Spontaneous restoration from the abnormal condition as in the SR condition of Drosophila was occasionally observed.
