Balsam fir sawfly. : Fo103-4/4-2022E-PDF
"The balsam fir sawfly (Neodiprion abietis) is a native defoliating insect of fir and spruce trees in Canada. Unlike spruce budworm, balsam fir sawfly prefers older needles, and feeding often leaves trees with a "lion's tail appearance" as older needles fall, and younger needles remain. This document describes the biology of the insect, type of damage caused, and the use of a sprayable formulation of a naturally occurring virus called AbietivTM as a management option for control of balsam fir sawfly"--Provided by publisher.
