WP 5 - Novel approaches for the improved trapping of wood-boring beetle tree pests ('Pest Trapping')

Workpackage 5

Partners: David Hall (Greenwich), Boonham (Fera)

Traps baited with volatile attractants based on pheromones and/or chemicals produced by host plants can provide highly sensitive tools for detection and monitoring of insect pests and are widely used in insect pest management. The traps are relatively cheap to purchase and deploy and they catch the adult stage before eggs are laid and larvae develop, providing an inherent early warning system for alien tree pests.

Lures and traps have been developed or are being developed for most of the key moth pests considered to be a threat to the UK, including the horse chestnut leafminer, pine lappet moth, oak and pine processionary moths. However this technology is less developed for beetles, including many of the critical wood-boring pests threatening the UK such as Asian longhorn beetle, emerald ash, pine sawyer beetles, citrus longhorn borer and the bronze birch borer.

The overall aim of this WP will be to develop better and more appropriate pest trapping technology for alien tree pests. We will identify attractants for key pest species where these are unknown. Of particular interest is the possibility of developing traps designed to attract more than one species to detect both known and unknown threats. We will establish the most appropriate designs of traps and lures, assess their performance and work with WP1 to establish effective, risk-based trapping networks involving a range of stakeholders.
