Transmission of<i>Leptographium procerum</i>to Eastern White Pine by<i>Hylobius pales</i>and<i>Pissodes nemorensis</i>(Coleoptera: Curculionidae)

Abstract

Two weevils, Hylobius pales and Pissodes nemorensis, were studied as potential vectors of the fungus Leptographium procerum, the causal agent of procerum root disease. Transmission of the fungus to living trees was determined by caging field-collected and artificially contaminated H. pales and P. nemorensis on eastern white pine (Pinus strobus) seedlings for 24 hr and by caging artificially contaminated H. pales on 5-yr-old trees for 5 days (...)
