Trees: Ips typographus

Lord Jones of Cheltenham Excerpts

Monday 1st November 2021 Lords Chamber

[Lord Benyon (Con)]

The noble Lord is aware that this is a very difficult area to get right. The beetle in question affects only mature spruce trees. It is very hard to use an insecticide on mature trees that would, first, be effective with the beetle, and secondly, not be further damaging to other species. It is part of the ongoing discussion with the Forestry Commission and its scientific experts.

[Lord Jones of Cheltenham (LD) [V]]

My Lords, for more than 200 years trapped trees, pheromone traps, which the Minister mentioned, treated trapped trees, standing trapped trees and lure-baited fallen wood have been used to capture and reduce numbers of this beetle. Does the Minister consider this a more environmentally sound way of dealing with the beetle than spraying with insecticides? What research is being carried out to discover whether these tried and tested techniques are no longer working?

[Lord Benyon (Con)]

We constantly ask ourselves whether we are getting this right. As things stand, the pheromone traps are very effective in identifying the range and quantity of beetles as they move around the country, but we have this matter constantly under review.
