Efektivitas Bacillus thurigiensis

Research output: Contribution to journalArticlepeer-review


Dengue hemorrhagic fever (DHF) is apublic health problemin Indonesia, especially in Jakarta, whichhasthe highest incidence of DHF in South East Asia. So far DHF control can only be done through vector (Ae.aegypti) elimination including biological control using Bacillus thuringiensis israelensis (Bti). The purpose of this study was to determine the effectiveness of liquid Bti in decreasing the density of Ae.aegypti in DHF red zone in District Cempaka Putih (West Cempaka Putih Village and Rawasari Village, Central Jakarta). This study used quasi-experimental design with liquid Bti application on 4 mL/m2 concentration as the intervention. Entomology survey was conducted in100 houses using a single method larval in March and April 2010. Effectiveness of
Bti was analyzed by McNemar test. Prior Bti applications in the Rawasari Village, 15 of 203 water containers were positive with Ae.aegypti larvae and in the West Cempaka Putih Village 9 of 189 water containers was positive. After application of Bti in the Rawasari Village,12 water containers were still positive while in the West Cempaka Putih no reduction of Aedes aegypti larvae (McNemar test p=0.629) was found. It is concluded that Bti is not effective in controlling the population density of Ae.aegypti.
