Description

There has been little recent research on control of damage by the white pine weevil, and available insecticides have been few and have become obsolete. Tests in Canada suggested that the insect growth-regulating chemical diflubenzeron was effective, and we have successfully repeated those tests in Maine using several formulations of Dimilin and several ground application systems. Aerial trials have not succeeded; the probable reasons for their failure are discussed. We present a general description of the weevil and its damage, approaches to control of damage, and specific recommendations for use of ground applications of Dimilin, which has recently become registered for this use.
