抄録: The ecology of Japanese encephalitis (JE) Virus has been investigated in Nagasaki area since 1964, in Amami-and Okinawa-islands since 1973. The virus isolation from overwintering female mosquitoes of Culex tritaeniorhynchus caught in winter and early spring in Nagasaki from 1965 to 1973 was quite unsuccessful. This result coincides with the fact that the incidence of gonotrophic dissociation in hibernated tritaeniorhynchus females was extremely rare. Consequently, we came to the supposition that the possibility of the presence of JE virus in overwintering tritaeniorhynchus might be greatly low in Nagasaki area. On the other hand, the persistence of JE virus in overwintering female mosquitoes of Culex tritaeniorhynchus and the maintenance of the cycle of the virus between vector mosquitoes and pigs through the year was demonstrated in Amami island in 1973 and in Okinawa island in 1976. However, the persistence and the cycle of the virus in vector mosquitoes and pigs were interrupted in both island at the following surveys. Taking these evidences into consideration, one may propose a speculation that the mosquitoes infected with the virus will be transported by the wind into southernpart of Japan including Amami- and Okinawa-islands from a certain epidemic area. As an attempt to verify these speculation a collection of transoceanic insects on East China Sea was made on board of a training ship of the Fisheries Faculty, Nagasaki University, "Nagasaki-Maru" from 24th June to 3rd July 1976. In this paper, the result of the captured transoceanic insects was recorded. Unfortunately, no mosquito was detected in this case, but regular migrants such as the dragonfly, Pantala flavescens, several moths and leaf-hoppers were recognized.
