Abstract: During the period from middle June to early July throught the three years 1976, 1977 and 1978, 3738 of transoceanic insects belonging to 60 species were captured. A great number of leaf-hoppers were taken composing 88 percent of total number of the insects captured in these years. A female of Culex tritaeniorhynchus captured on the first of July in 1978 was found to have copulated but likely unengorged, giving negative data in the subsequent virus isolation test. However, we have records that 8 females of vector mosquito (Hayashi et al., 1975) and 90 female of them (Asahina, 1970) were captured on the sea in 1973, and 1969, respectively. We consider, on these evidences, that infected vector mosquitoes may be able to disperse over the sea on the wind. Most of the other transoceanic insects now captured seems to be obligatory fliers and the majority of them are belonging to agricultural pests. The finding of Simulium sp. and Culicoides, the latter may carry akabane virus which causes bovine abortion, may be of particular interest. Further investigation on the ecology of transoceanic insects including Culex tritaeniorhynchus and Culicoides midges seems urgently needed.
