Notes: The biology and ecology of the diaspidid Pseudaulacaspis pentagona, a pest of peach, plum, apricot, cherry, mulberry, Camellia and lilac, was studied in Shanghai, China. There were three generations a year, the inseminated female overwintering in scales. The female oviposited in late March. Prepupation occurred in mid-May, and males emerged from pupae in mid-late June. Females did not undergo the prepupal and pupal stages. Females deposited 136-304 eggs (a mean of 229) each in June. Nymphs of the 2nd and 3rd generations hatched in early-mid-July and September, respectively. The diaspidid was preyed on by the coccinellid Chilocorus kuwanae and the nitidulid Cybocephalus, and parasitized by the aphelinids Aphytis chrysomphali and Marietta sp.
