In 2014, the seasonal abundance of adult thrips in paddy fields in Shizuoka Prefecture was investigated by using blue sticky traps, and the incidence of speckled rice damage by the insects was assessed. The most dominant thrips species was Stenchaetothrips biformis (Bagnall), followed by Thrips palmi Karny. From 26% to 38% of all speckled rice was black spotted rice. It is considered that many black spotted rice is caused by thrips.
