A new species of the genus cricotopus (Diptera: Chironomidae), a pest of rice in seosan, Korea

Abstract

We found some larvae of non‐biting midges (Diptera: Chironomidae) that injured rice crops by feeding on seeds and/or roots in the reclaimed rice fields in Seosan, Chungchongnam‐do, Korea, in May 1997. Four instar larvae were collected and reared in the laboratory‐ This pest species of the rice plant was identified as a new species of Cricotopus, similar to C. sylvestris. The main differences are the color pattern of the abdominal tergites. Both adult and immature stages of the new species are described with illustrations
