| Research Abstract |
Nealsomyia rufella (Diptera; Tachinidae) is a host specific parasitic fly of the bagworm, Eumeta japonica (Lepidoptera, Psychidae). N. rufella invaded Japan in about 1995 and it drove E. japonica population into the extinction state so as not to find E. japonica population in various parts of Japan. In Kochi prefecture, E. japonica population was not seen as much as before either, but kept in small population up to the present day. At the stage that passed from an invasion of N. rufella for 15 years, the situation of E. japonica population Kochi prefecture was investigated and the factor that E. japonica did not become extinct was discussed.
