Rapid assessment of the need for a detailed Pest Risk Analysis for Monterey pine aphid, Essigella californica
This rapid assessment shows:
Likelihood of entry was: LIKELY on plants for planting, taking into account the fact the aphid has arrived and was found on a small number of trees at one locality in west London, and a second population is established at a location in Kent.
Entry was UNLIKELY or MODERATELY LIKELY for the other three pathways considered.
Likelihood of establishment is: HIGH The climate of the UK is suitable for establishment and spread, and all Pinus species can act as hosts.
Economic impact is expected to be: LOW, but there is potential for interaction with red band needle blight.
Endangered area: all of the UK, except perhaps the far north and higher altitudes.
Risk management: Infested trees could be sprayed with insecticide, but this is only likely to be practical for smaller trees.
