What is Elaeagnus sucker?
Elaeagnus sucker or psyllid is a sap sucking insect. These are a group of sap-feeding insects allied to aphids.
Elaeagnus sucker originates from eastern Asia and was first detected in Britain in 2002. It has spread rapidly and now occurs throughout most of England and parts of Wales.
When elaeagnus sucker first arrived in Britain, it spread very rapidly and was feared to become a major problem for Elaeagnus. In many places however, the high populations, seen soon after the insects arrival, are no longer occurring. This suggests that natural enemies may be having an effect on this insect helping to keep it at relatively low levels at which serious damage does not occur.
