The host range of Otiorhynchus sulcatus (F.) was investigated in cultivated and wild plants in the laboratory. Out of 108 species of candidate plants, representing 49 families, the adults fed on the leaves of 101 species in 46 families. The larvae fed on the roots of 55 species in 24 families, out of 68 candidates, in 29 families. These "positive" plants were classified as severe, moderate and light, according to the extent of injury caused by adult and larval feeding. Ninety species in 45 families were newly recorded hosts for adults and 46 species in 21 families for larvae. O. sulcatus is highly polyphagous but it appears that the favorite hosts of both adults and larvae are those in the rose family, Rosaceae.
