^ᵀᴹBioControl-1

Targeted Biological Control of Douglas-Fir Tussock Moth

^ᵀᴹBioControl-1 is a highly selective biological insecticide developed for the control of Douglas-Fir Tussock Moth (Orgyia pseudotsugata) larvae. Manufactured by Andermatt Canada, this baculovirus-based solution provides effective control of a major forest defoliator while preserving beneficial insects, pollinators, and other non-target organisms.

Containing a naturally occurring nucleopolyhedrovirus, ^ᵀᴹBioControl-1 works when feeding larvae ingest treated foliage. Following infection, the virus replicates within the insect, causing disease and mortality in feeding larvae. Its species-specific mode of action makes it a valuable tool for sustainable forestry and integrated pest management programs.

Target Pest Information

Douglas-Fir Tussock Moth

(Orgyia pseudotsugata)

Douglas-Fir Tussock Moth is a native defoliating insect found throughout western North America. Larvae feed on the needles of Douglas-fir, true firs, and other conifer species, causing significant defoliation during outbreak periods. Repeated feeding can reduce tree growth, weaken stands, and increase susceptibility to secondary pests and environmental stress.

Severe outbreaks can affect large forested areas and impact both commercial and natural forest resources. Monitoring population levels and implementing appropriate management strategies can help reduce the impact of infestations.
