Book Description
Summarizes studies on wildlife predation of the white pine weevil (Pissodes strobi Peck.), a significant pest in Ontario jack pine forests. Investigations were conducted in northern Ontario jack pine plantations and involved: assessment of small-mammal predation using control (open) and screened cages containing weevils, and examination of the effects of type of reforestation, distance from slash, presence of competing vegetation, and depth of the duff layer on adult weevil overwintering mortality; and examination of total mortality of weevil pupae and mortality due to bird predation in five planted stands and five seeded stands. Implications of the results for integrated pest management are discussed.
