Efektivitas Pemanasan Kelambu Berinsektisida, Olyset terhadap Nyamuk Aedes aegypti (Diptera: Culicidae)
The aim of this research was to know the effectiveness of heating insecticide bednet, against the mosquito Aedes aegypti. As many as 240 Olyset samples from eleven health centers in Bangka District were tested its effectiveness against mosquitoes with WHO ball test method. In these test, there were used 25 Aedes aegypti female, and 3-5 days old. Bednet sample treatments was collected from six health centreareas that the people washed and heated the nets. Control samples was taken from five health centre areas where the people only washed their nets without heating. Sample collections were done for four periods with interval time of three months, from September 2007 to June 2008. The observation on knockdown effect/mortality of Aedes aegypti was done on 30 minutes, 60 minutes, and 24 hours after 3 minutes exposured. The effectiveness of Olyset bed net was based on the value of knock-down time 50% (KT-50). The result showed that the difference of the average percentage mortality of Aedes aegypti after 30 minutes, 60 minutes and 24 hours exposured on period of I, II, III and IV in the control groups and on the treatment groups were not significant enough. However, based on the value of KT-50, the heat regeneration on Olyset net has a better effectiveness compared with the control (p
