Efficacy of Spinetoram, Methoxyfenozide and Lambda-Cyhalothrin for Control of European Pine Shoot Moth (Rhyacionia bouliana)

Four trials were conducted in 2017 and 2018 in British Columbia, Canada, to test newer insecticides for control of European pine shoot moth in a conifer seed orchard. In each of the four trials, the insecticides spinetoram and lambda-cyhalothrin gave over 80-percent reduction in insect damage when compared to untreated. The insecticide methoxyfenozide was tested in one trial and also provided over 80-percent control. In two trials, excellent control of the pest was obtained with one application made in late April, targeting the larvae moving from overwintering sites to new developing shoots. In the other two trials, excellent control was obtained with two consecutive applications made in mid-June and early July, targeting adults and newly hatched larvae on new plant shoots. This work helped generate data for label extension of the products.
