Turnip Mosaic Virus is also vectored by this aphid. There are many generations of this aphid throughout the year in Hawaii. In Hawaii the average life span is about 18 days. The life span represents the period from birth of the nymphs to the death of the adult. Reproduction in Hawaii does not involve mating and egg laying.
Females give birth to live female nymphs.
As a consequence of this type of reproduction, populations are composed solely of females and there are no males. Since winters in Hawaii are mild, there is no need for an overwintering egg stage. In temperate regions, these aphids overwinter during the egg stage. The shiny black eggs are often laid on the bark of fruit trees. No eggs are found in Hawaii.
