This study proposed a design that could be used for anti-mosquito fumigation. Any mosquito-repellent materials can be used with it. It is made from thrown-away cans. It is looked forward to that the junked can would become an invaluable material for fumigation especially in the barangays or in camping areas where there are no available commercial repellents. It won third in Individual, Cluster 1 Physical Science during the 2007 Regional Science Fair.

ABSTRACT

The practicability and efficiency of a fumigation gadget made from tin can were explored through two-group ratings. A regular sized sardine tin can was designed into a fumigation gadget following the principles of oxygen combustion. Pieces of paper were used as fire starter. The upper fillings were dried chopped leaves of mosquito repellent Madre de cacao. The time it took to smoke and the numbers of repelled caged mosquitoes were counted. Result showed an average of 3.30 - minute fumigation. The fumes were concentrated at the start of fuming. 100% of the caged mosquitoes were repelled. For practicability, a mean of 8.6 was rated by group A and a mean of 7.6 by B. The T –test analysis revealed that such ratings did not significantly differ with a t – value of 1.043, which had a significance level of .328. On the efficiency, the mean rating given by group A was 9.00 and 9.20 for B. With a t – value of -.232, it was said that the ratings did not significantly differ from each other at a level of .822. It was then concluded that the gadget was both practical and efficient. The researcher therefore recommended that this gadget be tried out in the households, camping sites and other mosquito vulnerable areas.
