BACKSTORY AND PROBELM Mosquitoes are a major cause of discomfort and distress in Australia, and in UoN it has become a nightmare for everyone. The global statistics shows a boom in mosquitoes borne diseases such as malaria, dengue, chikungunya, filariasis, leptospirosis and many more. This makes the mosquito as one of the most menacing creature on the planet. Australia is very famous for wetlands, marshes and waterbodies and interestingly these stagnant water bodies are the breeding grounds for mosquitoes. The unnoticed other areas are the sewages and drainages where these mosquitoes multiply. Especially, our University is situated in a wetland area serving as the ideal location for mosquito breeding. Basic research shows that if the breeding is controlled, the population of mosquitoes can be limited. The peak in mosquito population is observed during warmer months when several mosquitoes are suddenly observed. Most of the adult mozzies die after summer but keep their offspring as winter eggs (dormant) in the ground or near the water bodies (some of the female mozzies hide in dark areas). During spring season, eggs merge with water and hatch suggesting water is needed for their breeding. Thus, elimination of mozzies during the hatching phase is the best method of controlling mozzie menace at UoN. IDEA & SOLUTION There are number of measures available to control the breeding of mosquitoes and thereby their population. But, most of the existing methods are creating problems to the habitat and ecosystem. In our approach, we are establishing natural biological methods that will not affect the ecosystem and balance the inhabitants around. Introducing guppy fishes (Poecilia reticulate) to the nearby waterbodies and drainage systems and use of BT (Bacillus thuringiensis bacteria) balls for land can considerably reduce the number of mosquitoes. The Guppies are ornamental fishes and they can feed on mosquito larvae and eggs. The research shows that Guppy fishes are one of the five most effective forms of dengue control. The BT balls can be prepared from Bacillus thuringiensis bacteria (toxins kill larvae) by mixing it with sand or compost. Thus, by releasing these tiny fishes in water bodies in wetland areas and around university can substantially reduce the mosquito population. The fish population would add to the beauty and elegance of the place. In wetlands, it does not create any environmental issues as it feeds on larvae and zooplanktons. It can also happily stay with other fishes and is tolerant to Australian climate. Thus, this approach can be established to control the population of mosquitoes not only in the University but also around all the places. The BT balls can be dispersed to various parts of University dry land during winter (by student volunteers) and it enriches the land with bacteria. During spring when the eggs start to hatch in the water logging areas toxins released from BT will destroy the larvae and eggs. The mosquitoes can fly over long distances and this control method is applicable to a wide area making it an effective controlling method.
