Abstract

Laboratory and field experiments showed that <i>Epitrix tuberis</i> Gent. had developed strains that were highly resistant to dieldrin and less so to DDT. Both adults and larvae were resistant to the cyclodiene insecticides. Strains resistant to cyclodienes were centered in the Salmon Arm and Vernon areas. Strains resistant to DDT had a wider range and were present as far north as Pavilion. All tuber flea beetles tested in the province were highly susceptible to diazinon and presumably to other organophosphorus compounds.
