Abstract

Two leafroller spades are major pests of apple in British Columbia, Archips argyrospilus (Walker) and Archips rosanus (Linnaeus). Field observations showed that both species overwinter in the egg stage and that larval emergence times are similar. Experiments demonstrated that both species are susceptible to sprays of azinphos-methyl, diazinon, or trichlorfon applied at either the pink bud or petal fall stages. Dipel (Bacillus thuringiensis) failed to control larvae of either species.
