摘要
171,348 mosquitoes and 4,353 other arthropods collected at three centres in Queensland in 1972-1976 yielded 151 strains of 18 viruses. Culex annulirostris was the major source of virus isolation but 42 strains from Aedes normanensis indicate it to be a vector of importance. Ross River and Kokobera viruses were isolated at Kowanyama in the dry season, a finding of interest as being compatible with year-round survival in vector-vertebrate cycles. Culex fatigans has in part replaced Culex annulirostris in peridomestic breeding sites at Kowanyama; the infrequency of virus isolation from it suggests that this replacement may lower arbovirus infection rates. Twelve strains were identified as viruses antigenically distinct from any previously isolated in Australia or New Guinea: Ch16129, shown by the International Reference Centre for Arboviruses to be a previously undescribed member of the Simbu Group (Facey's Paddock virus), Ch16313 (Murweh), Ch19520 (Parker's Farm) and Ch19546 (Little Sussex). The remaining strains were identified as viruses previously known in Australia, but included many new host or geographical records.
