SUMMARY Sixty strains of 11 viruses were isolated from 25,901 mosquitoes of 32 species collected at Mitchell River Mission, Cairns and Normanton in 1960 and 1961. The viruses, the local prototype strains and the mosquito species, geographical location and year of repeatable isolations, were: Group A: Sindbis (MRM39) from Culex annulirostris and Aedes normanensis at Mitchell River (1960) and Cairns (1961); AMM2021 (N544) from Anopheles amictus amictus and Culex bitaeniorhynchus at Normanton (1961). Group B: Murray Valley encephalitis virus from C. annulirostris at Mitchell River (1960 and 1961); Kunjin (MRM16) from C. annulirostris at Mitchell River (1960); Kokobera (MRM32) from C. annulirostris at Mitchell River (1960 and 1961); Edge Hill (C281) from Aedes vigilax and C. annulirostris at Cairns (1961); Stratford (C338) from Ae. vigilax at Cairns (1961). Koongol group: Koongol (MRM31) from C. anulirostris at Mitchell River (1960) and Normanton (1961); Wongal (MRM168) from C. anulirostris at Mitchell River (1960 and 1961). Ungrouped: MRM1 (found resistant to ether and sodium desoxycholate) from C. anulirostris at Mitchell River (1960); Mapputta (MRM186) from Anopheles meraukensis at Mitchell River (1960) (not reisolated). C. annulirostris was the commonest mosquito collected (12,124) and the source of 44 of the virus strains. Eight of the viruses appear to be new. One (Murray Valley encephalitis virus) has previously been isolated from man in Australia and two (Sindbis and AMM 2021) from mosquitoes elsewhere.

Three strains of Japanese encephalitis (JE) virus were recovered from mosquitoes collected in Lombok Indonesia, during March 1979, from pools of Anopheles vagus, An. annularis and Culex tritaenior t ynchus respectively. This is believed to be the first report of isolation of JE virus from An. vagus. The frequencies of JE viral infection in zoophilic Ampheles species were higher than in Cx tritaeniorhynchus, the principle vector of JE virus in Asia. The low frequency of infection in Cx tritaeniorhynchus and the relatively infrequent raising of pigs may account for the low prevalence of JE neutralixing antibodies in the human populations of Lombok.

“…It seems favorable to consider that it appeared in Japan rather recently, taking the following facts into account. Firstly, it had not been isolated by the extensive mosquito surveys hitherto tried by the previous investigators (Mitamura et al, 1938;Buescher, 1956;Buescher et al, 1959). Secondly, no antibody againt Akabane has been shown as yet by the serological survey among residents in Gumma Prefecture even though the virus is harbored in common mosquitoes in the survey area.…”
