Insect parasites and predators of Phyllophaga anxia (LeConte) (Col., Scarabaeidae) in Quebec, Canada

Phyllophaga anxia (LeConte), is the most common and destructive species of June beetle in the province of Quebec, Canada. In the course of a systematic 4‐year survey in southern Quebec, 29 species (belonging to 13 families in 3 orders) of parasitic and predaceous insects were found associated with the pest. Tachinid flies and tiphiid wasps were the most common parasites. The roles of the parasites and predators of P. anxia are reviewed. The survey showed that these natural enemies had low impact on field populations of the June beetle.
