The aim of the present study was to describe the phytophagous fauna of strawberries in Latvia. This study was carried out in 2000–2004 on plantations in Tukums, Rîga, Do- bele, and Limbaþi districts. Insects were collected from strawberry fields by pitfall trapping, sweep netting and leaf sampling methods. A total of 137 insect belonging to seven orders and 41 families were identified to species. Of the phytophagous insects, the order Orthoptera was represented by one species, other orders by a larger number of species: (3), Dip- tera (16), (20), Thysanoptera (21), Hemiptera (39), and Coleoptera (37). Of the re- corded insects, 48 species have a status of general strawberry pests. Key words: Fragaria × ananassa, strawberry pests, insect diversity.
