aPhinity HL ®

Advanced Hemlock Looper Detection and Monitoring

aPhinity HL is a pheromone lure developed to support the detection and monitoring of Hemlock Looper (Lambdina fiscellaria) populations in Canadian forests. Designed for forestry professionals, researchers, and forest health programs, it provides a reliable monitoring tool for both low- and high-density populations.

Containing a di-methylated hydrocarbon blend that mimics the natural female sex pheromone, the lure attracts male moths to sticky traps for population monitoring. By supporting early detection and ongoing surveillance, aPhinity HL helps improve decision-making and strengthen integrated forest pest management programs.

Target Pest Information

Hemlock Looper

(Lambdina fiscellaria)

Hemlock Looper is one of Canada's most important native forest defoliators, capable of causing significant damage to conifer forests during outbreak years. Larvae feed on the needles of host trees, particularly balsam fir and hemlock, reducing tree vigour and, in severe infestations, contributing to widespread tree mortality. Population levels can fluctuate dramatically over time, making regular monitoring essential for detecting population increases before visible damage becomes widespread. Effective surveillance helps forestry professionals assess risk, support management decisions, and protect forest resources.
