Cen, D.H. 1986 A study on Russelaspis pustulans (Ckll.), a new insect pest on tea trees in China.. Plant Protection 12(6): 27-28.
Notes: The biology of the coccid Russellaspis pustulans [Asterolecanium pustulans], a recently discovered pest of tea in Zhejiang, China, was studied in 1982-84. The morphology of the life stages is described. There was one generation a year and 2nd-instar nymphs overwintered on tea branches. The overwintered female nymphs became adults in late April, were mature in mid-late May and laid eggs in mid-late July. The male nymphs developed into prepupae in late April and emerged and mated in mid-May. It was recommended that severely damaged tea trees should be ratooned at 25 cm high and burned. Application of 50% malathion, 80% dichlorvos or 20% fenvalerate at hatching (mid-late July) gave high mortality of A. pustulans.
