The 1989 outbreak of the green spruce aphid, Elatobium abietinum


, : The 1989 outbreak of the green spruce aphid, Elatobium abietinum. Research Information Note Forestry Commission Research Division ( 161): 2 pp.

Severe attacks were reported from some areas of the UK attributed to autumn and winter weather in 1988-89 being ideal for successful overwintering, and summer drought exacerbating the effects.

A general introduction to the biology of this pest, a mass outbreak of which occurred in Switzerland in 1980 (the last was in 1961).

Compared with survival on mature needles, survival of aphids on young needles was significantly red...
