Abstract

This study aims to determine the effective concentration and mortality of Bti who have expired mosquito larvae Ae. aegypti. This research was conducted in December 2018 at the Zoology Laboratory II, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. This research was conducted with RAL (Complete Random Design) using Bti expiration as the main factor with 6 levels of concentration: 0 ppm (positive control), 50 ppm, 100 ppm, 150 ppm, 200 ppm, 250 ppm, 300 ppm and normal Bti 20 ppm as a negative control consisting of 4 replications. As a parameter is the mortality rate of larvae Ae. aegypti. Data was analyzed using ANOVA test and continued with LSD test at the 5% level. The results showed that the Bti concentration expiry of 300 ppm the highest expiration Bti concentration and the longest contact time to cause death to the larvae Ae. aegypti up to 100%. In conclusion, the Bti expired has an effective and influence on the death of the larvae Ae. aegypti.
