ord river arboviruses--isolations from hundred and thirty presumptive viruses have been isolated from 485 pools made from 23,872 mosquitoes collected in the ord river area of north-west australia. one hundred and eleven of the virus isolates isolates came from pools of culex annulirostis, the dominant mosquito species caught in the vicinity of kununurra. forty-five of the viruses pathogenic for newborn mice have been further characterized-19 as flaviviruses, 1 alphavirus, 9 koongol, 1 mapputta and 15 non-haemagglutinating viruses ...197614613
two possible mechanisms for survival and initiation of murray valley encephalitis virus activity in the kimberley region of western australia.two possible mechanisms are described for the initiation of murray valley encephalitis (mve) virus activity in arid, epizootic regions of tropical australia. virus isolations were made from mosquitoes trapped shortly after the first heavy wet season rains and flooding in the east kimberley, which followed approximately nine months of drought. a number of isolates of mve virus were obtained, including isolates from pools of blood-engorged culex annulirostris mosquitoes and from a single pool of m ...19957625542
point source inoculation of mesocyclops (copepoda: cyclopidae) gives widespread control of ochlerotatus and aedes (diptera: culicidae) immatures in service manholes and pits in north queensland, australia.this study details the novel application of predacious copepods, genus mesocyclops, for control of ochlerotatus tremulus (theobald) group and aedes aegypti (l.) mosquito larvae in subterranean habitats in north queensland, australia. during june 1997, 50 mesocyclops sp. 1 were inoculated into one service manhole in south townsville. wet season rainfall and flooding in both 1998 and 2000 was responsible for the dispersal of copepods via the underground pipe system to 29 of 35 manholes over an are ...200212061442
the importance of subterranean mosquito habitat to arbovirus vector control strategies in north queensland, north queensland, 14 localities were surveyed for mosquito larvae (third and fourth instar) during summer/autumn and winter from 1996 to 1999. absolute population numbers in subterranean habitats, mainly service manholes and pits (97%) but also some wells, septic tanks, storm drains, and sumps, were expressed as a proportion of total numbers in these sites plus surface sites within a 100-m radius. when correction factors were applied to subterranean samples, the 472,477 larvae mainly of aedes ...200011126539
a sticky entry-exit trap for sampling mosquitoes in subterranean habitats.this paper addresses the problems of sampling adult aedes aegypti and other mosquitoes which utilize subterranean habitats such as wells and service manholes. the sticky pipe trap is a simple device with an adhesive paper insert that can be clipped to the undersides of service manholes to record the entry and exit of adult mosquitoes through the keyhole openings. this trap was 1st used successfully in townsville, charters towers, and saunders beach in north queensland, australia, in dry seasons ...200011081658
