EFEKTIVITAS BUAH BELIMBING WULUH (Averrhoa bilimbi L.) UNTUK MEMBUNUH LARVA NYAMUK Anopheles aconitus INSTAR III

Abstract

Belimbing wuluh (Averrhoa bilimbi L.) contains akaloids and saponins, which possess larvacidal properties. This study was aimed to find out the effectiveness of Averrhoa bilimbi L. juice to kill Anopheles aconitus instar III larvae. It was an experimental study with post-test-only-with-control-group design, in which the subjects were divided into two groups, i.e. a treatment and control groups. Each treatment as well as control group consisted of 25 mosquito larvae, and the treatments were given in quadruplicate. The death rates of larvae treated with 2.0%, 2,5%, 3,0%, 3,5%, 4,0%, 4,5%, and 5% of Averrhoa bilimbi L. juice were 71%, 79%, 84%, 92%, 96%, 100% and 100%. Kruskall-Wallis analysis to the data revealed that there was significant influence between the treatment and the larvae death at the dose 4,5%, with p=0,000 < α = 0,01.
