Available in PDF, EPUB and Kindle. Book excerpt: As a group, pine stem rusts are considered the most important forest tree disease problem in Canada. This paper proposes a new strategy for biological control of pine stem rusts with aggressive hyperparasites using certain free-moving organisms (mainly insects) as possible vectors of hyperparasitic micro-organisms. A candidate vector organism & mycoparasite, found through a literature search, are proposed for use in this strategy and a brief description of the life cycle of the candidate vector is presented.
