Zhang, J.Y., Kong, D.S., & Liu, H.J. 2001 [The occurrence of Korean globose scale in the River's (Western Corridor region of Gansu province and its control.)]. China Fruits No. 2: 8-10.

Notes: Observations on the Korean globose scale (Didesmococcus koreanus) showed that it infests apple, pear, peach, plum and apricot trees; has one generation a year; and overwinters as larvae. Spraying with different concentrations of lime sulfur [calcium polysulfide], Optunal [1-methylethyl 2-[(aminomethoxyphosphinothioyl)oxy]benzoate], omethoate and Decis [deltamethrin] during different periods in a field experiment conducted during 1996-98 showed that control of the plant pest can be achieved by spraying lime sulfur before bud break.
