| an overview of remote sensing and gis for surveillance of mosquito vector habitats and risk assessment. | this paper provides a brief nontechnical overview of the use of remote sensing to achieve multiple objectives, focusing on mosquito management. it also shows how geographic information systems, combined with remote sensing analysis, have the potential to assist in minimizing disease risk. examples are used from subtropical queensland, australia, where the salt marsh mosquito, aedes vigilax, and the freshwater species, culex annulirostris, are vectors of human arbovirus diseases such as ross rive ... | 1998 | 9673930 |
| entomological investigations of an outbreak of japanese encephalitis virus in the torres strait, australia, in 1998. | japanese encephalitis (je) virus first appeared in australia in 1995, when three clinical cases (two fatal) were diagnosed in residents on badu island in the torres strait, northern queensland. more recently, two confirmed human je cases were reported in the torres strait islands and cape york peninsula, in northern queensland in 1998. shortly after je virus activity was detected in humans and sentinel pigs on badu island in 1998, adult mosquitoes were collected using co2 and octenol-baited cdc ... | 2001 | 11476340 |
| vector competence of australian mosquitoes (diptera: culicidae) for japanese encephalitis virus. | australian mosquitoes were evaluated for their ability to become infected with and transmit a torres strait strain of japanese encephalitis virus. mosquitoes, which were obtained from either laboratory colonies and collected using centers for disease control and prevention light traps baited with co2 and octenol or reared from larvae, were infected by feeding on a blood/sucrose solution containing 10(4.5 +/- 0.1) porcine stable-equine kidney (ps-ek) tissue culture infectious dose50/mosquito of t ... | 2003 | 12597658 |
| collection of wind-borne haematophagous insects in the torres strait, australia. | circumstantial evidence has implicated wind-borne mosquitoes (diptera: culicidae) in the introduction of japanese encephalitis (je) virus into australia from the new guinea mainland. a study was initiated on saibai island in the northern torres strait, during january and february 2000, to identify the potential source of insects collected in aerial (kytoon) and surface-level traps. wind speed and direction were recorded to determine wind profiles during insect sampling. northerly winds capable o ... | 2003 | 12680932 |
| flavivirus isolations from mosquitoes collected from western cape york peninsula, australia, 1999-2000. | after the 1st appearance of japanese encephalitis virus (je) on mainland australia in 1998, a study was undertaken to investigate whether je had become established in enzootic transmission cycles on western cape york peninsula. adult mosquitoes were collected during the late wet season from kowanyama and pormpuraaw in april 1999, and pormpuraaw and barr's yard in april 2000. despite processing 269,270 mosquitoes for virus isolation, no isolates of je were obtained. however, other flaviviruses co ... | 2003 | 14710742 |
| experimental infection of culex annulirostris, culex gelidus, and aedes vigilax with a yellow fever/japanese encephalitis virus vaccine chimera (chimerivax-je). | australian mosquitoes from which japanese encephalitis virus (jev) has been recovered (culex annulirostris, culex gelidus, and aedes vigilax) were assessed for their ability to be infected with the chimerivax-je vaccine, with yellow fever vaccine virus 17d (yf 17d) from which the backbone of chimerivax-je vaccine is derived and with jev-nakayama. none of the mosquitoes became infected after being fed orally with 6.1 log(10) plaque-forming units (pfu)/ml of chimerivax-je vaccine, which is greater ... | 2006 | 17038690 |
