The cyclamen mite, Phytonemus pallidus (Banks) (Acari: Tarsonemidae) has been considered as a lower priority pest compared to broad mite, Polyphagotarsonemus latus mostly because the cyclamen mite had rarely occurred in economic plants in Korea. This is the first report of field occurrence of the cyclamen mite on economic crop, strawberry. From the summer cultivation of strawberry in Samcheok, Gangwon province, infestation of the cyclamen mites was confirmed in 2010. Infested leaves and sepals turned discolored on the tip and stunted growth producing blotched appearance, distorted leaves, and malformed fruits. Infestation was found on late July and spreaded quickly until mid September, but only in imported Sharott variety not in domestic Goha variety. Released Amblyseius swirkii survived and were found in the damaged fruits even 1 month after release.
