Wang, Z.M., & Xu, X.M. 2006 Biological observation and chemical control of the white wax scale, an invasive alien species in Changchun City.. Jilin Agricultural University 28(2): 152-154.

Notes: The biological characteristics of white wax scale (Ericerus pela), and the chemical control measures used on the pest were evaluated. Mated females pass the winter on twigs and small branches of Ligustrum obtusifolium. In Changchun (Jilin, China), females develop in mid-April and produce a large number of eggs from early to late May. Eggs hatch in early June and tiny crawlers begin to move on the leaf surface. In late August, females settle down for winter after mating with males. The insecticides chlorpyrifos and alpha-cypermethrin were the most effective in killing nymphs.
