Abstract

Black-horned tree crickets (Oecanthus nigricornis F. Walker) were reared from rows of eggs laid in the twigs of recently planted peach trees in Essex County, Ontario. Eggs were laid in September and hatched the following June. Egg laying injury was most frequent at the edges of peach blocks. The injuries did not become infection sites for peach canker fungi (Cytospora cincta Sacc. and C. leucostoma Sacc). Twenty-one per cent of the twigs died above the injury and eggs then hatched, but if the injuries healed and the twigs survived, very few eggs hatched.
