Abstract

Dengue Haemorrhagic Fever (DHF) is a disease that has become a public health problem in Jakarta, including Rawasari Village. One of the way that can be done to control the dengue vector is using biolarvacide, that is known as Bacillus thuringiensis israelensis (Bti). The purpose of this study is to examine the effectiveness of Bti larvacide in controlling dengue vectors in water containers. This research is using quasi-experimental design with intervention of Bti applications liquid form with  4 ml/m2 of concentration. Before Bti application which was taken on 14 of February 2010 and after Bti applications on 15 of March 2010 in Rawasari Village, Jakara Pusat. The entomology survey is conducted with single-larval container method in water containers of 100 houses. The data is processed using SPSS version 20 with and analyzed by using McNemar test. Results showed that after application of Bti, the number of Ae.aegypti larvae decreased from 15 to 12 of positive larvae. As a result the  McNemar test shows P = 0.629, which means that the density of Ae.aegypti larvae remains high. So that, Bti cannot reduce the existence of Ae.aegypti larvae in the water containers with the concentration of 4 ml/m2.
