The pest had 1 generation a year and diapaused in the egg stage in soil for about 7 months. Each female laid an average of 300 eggs over 12 days. Nymphs started to hatch in mid-December. Mealy powder appeared just before the moult to the 3rd instar. The nymphal period lasted 12-39 days and the pupal period 10 days. Males lived for 4-6 days and females for 18-51 days.
