Zhao, W.D. 2002 [The damage of Korean hardy scale and its control.]. China Fruits No.4: 55.

Notes: Korean hardy [globose?] scale (Didesmococcus koreanus) is an important pest for peach and apricot trees. It has only one generation/year, with nymphs hibernating on branches and starting to attack branches in mid-March. Control is possible by spraying lime sulfur [calcium polysulfide] before bud bursting.
