Results of previous vector mosquito surveys and the regular mosquito monitoring programme carried out by the
Health Surveyor, Mr W. Morgan, indicate Alyangula does not have a marked mosquito problem for most of the year. Apart from relatively low numbers of container breeding mosquitoes it would appear Aedes vigilax is the principal pest and disease vector mosquito affecting Alyangula.
Previous vector mosquito surveys have identified a number of potential breeding sites, for this species, that could be of significance to Alyangula. In liaison with the Groote Eylandt Mining Company Environmental Officer
(Mr ALAN Philliskirk) and the Alyangula Health Surveyor these sites were visited following the spring tides of
December 4-7 (maximum of 1.6m). Potential breeding sites with limited access were studied from aerial photography supplied by the Groote Eylandt Mining Company.
