Gall-Inducing Species of the Family Cecidomyiidae (Diptera) Recorded from the Korean Peninsula and Surrounding Islands,in Comparison with the Gall-Midge Fauna of Japan

Abstract

A total of 52 gall-inducing species of Cecidomyiidae (Diptera) (53 in the sorts of midge gall, because one polyphagous species was included) were recognized to occur in the Korean Peninsula (including surrounding islands) through literature survey, field surveys by Dr. K. Yamagishi and ourselves, and by examining photographs of arthropod galls taken by the late Prof. W.-H. Paik and one of us, JCP. The previous and current identification of these Korean gall midges relied largely upon their gall morph and host plant species that correspond to those of Japanese gall midges. The identification of these gall midges was considered to be mostly reliable, because recent DNA analysis suggested that some South Korean gall midges were identical with Japanese gall midges when they induce the same sorts of gall on the same host plants as those in Japan. At the moment, 47 (88.7 %) out of the 53 sorts of Korean midge galls were commonto Japan. This means that more numerousmidge galls will be detected in the * Contribution from the Entomological Laboratory, Faculty of Agriculture, Kyushu University, Fukuoka (Ser. 5, No. 1 10). 58 J.-C.
