SUMMARY Tomato crops in Lanarkshire, Scotland, were surveyed in 1974–77 to assess the incidence of glasshouse whitefly ( Trialeurodes vaporariorum (Westw.)), glasshouse red spider mite (Tetranychus urticae (Koch)) and tomato moth (Lacanobia oleracea (L.)). Glasshouse red spider mite infested 65–76 per cent of the cropped area but glasshouse white‐fly, which affected 62–65 per cent of the cropped area, was the most damaging pest. The survey indicated the success of biological control of whitefly by its parasite, Encarsia formosa Gahan, in 1977 and demonstrated the potential for biological control by contract operators. The percentage of holdings with fruit damaged by tomato moth increased from 4 in 1974 to 23 in 1977.
