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 ...200111476340
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 ...200312597658
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 ...200312680932
climatic, high tide and vector variables and the transmission of ross river virus.this report assesses the impact of the variability in environmental and vector factors on the transmission of ross river virus (rrv) in brisbane, australia. poisson time series regression analyses were conducted using monthly data on the counts of rrv cases, climate variables (southern oscillation index and rainfall), high tides and mosquito density for the period of 1998-2001. the results indicate that increases in the high tide (relative risk (rr): 1.65; 95% confidence interval (ci): 1.20-2.26 ...200516248864
efficacy of vectobac (bacillus thuringiensis variety israelensis) formulations for mosquito control in australia.laboratory bioassays were conducted on the efficacy of a water-dispersible granule (wg) formulation of bacillus thuringiensis variety israelensis (vectobac wg; active ingredient [ai]: 3,000 bti international toxic units [itu]/mg) against third instars of six common australian mosquito species, aedes aegypti (l.), ochlerotatus vigilax (skuse), ochlerotatus notoscriptus (skuse), culex sitiens wiedemann, culex annulirostris skuse, and culex quinquefasciatus say. the normal model for log-linear mort ...200314977116
