Jurnal Effects of Areca Catechu L. Seed Extract on Mortality Anopheles Vagus Larvae

Abstract : Bioinsecticide is an
alternative to overcome larvae resistence to insecticide and reduce environtment
contamination. This research is to analyze the effects of areca seed extract to
An. vagus larvae. The research is taken time in 2017. The research design is
laboratory experiment with post test only control group design. The areca seed
and An. vagus larva are collected from Southwest Sumba District, then the
seeds were extracted with ultrasonic method. The effect of the extract is
evaluated based on LC50 and LC90 value. The sample from 25 An. vagus larvae
instar III are released into areca seed extract on 500, 1250, 2000, 2750, 3500,
4250 and 5000 ppm and observed within 6, 12, 18 and 24 hours and 6 repetition.
The data then analyzed with probit analysis and ANOVA. The areca seed extract
eliminates An. vagus larva as much as 61.33% under 6 hours exposure with 5000
ppm, 52% mortality larvae on 12 hours with 4250 ppm, 56% mortality larvae on 18
hours with 3500 ppm, and 55% larval mortality on 24 hours with 2750 ppm. The
value of LC50 and LC90 on 6, 12, 18 and 24 hours are 4654.374 and 6320,732;
3717.286 and 5127.489 ppm; 3201,473 and 4775,206 ppm; 2385,297 and 4496,708
ppm. There is variation of larva mortality percentage average on every
concentration and exposure time, the higher the concentration and exposure time
the higher An. vagus larva mortality.
