Abstract

Dengue hemorrhagic fever (DHF) is one of the major public health problem in Indonesia because of its high incidence. Specifically one area in Jakarta which is Rawasari village is known as a 'red zone' area in which the transmission of DHF is high. Several preventive measures were proposed to control the vector, Ae. aegypti, such as the use of biological agent. In the current study, Bacillus thuringiensis israelensis (Bti) was used. Hence this study aimed to evaluate the effectiveness of Bti in reducing the distribution of Ae. aegypti in Rawasari village. Data collection were done before (14th of February 2010) and after (14 th of March 2010) the intervention of Bti. Out of 100 houses included, House index was 18% in pre-test and 12% in post-test. This decreament is statistically significant (p = 0.00 on McNemmar test). Despite this significance result, improvement were found mostly on non-water containers (non-TPA) that did not receive Bti. This suggests that the reduction of HI was not due to the use of Bti and that the use of Bti is not effective in reducing the distribution of Ae. aegypti.
