Abstract

Insidence of filariasis in Indonesia is still increasing and this disease may cause many disabilities. In order to decrease the incidence rate, we can interfere with the life cycle of Culex, the filariasis vector, by using  larvicides.    Most  larvicides  sold  in  the  market  contain  chemical  substances,  such  as  temephos. Therefore, it is necessary to find out more friendly natural larvicides, which are effective but safe; one of them is Papaya Leaves Infusion (PLI). The aim of this research is to find out the effectiveness of PLI as a larvicide  of  Culex  sp.  and  compare  it  with  temephos  powder.  This  research  is  a  real  comparative experimental laboratory study using complete randomized design. 720 Culex’ larvae were divided into 6 treatment  groups,  each  group  was  given  Papaya’s  Leaves  Infusion  1%,  1.5%,  2%,  2.5%,  aquadest (negative  control),  and  temephos  1%  (positive  control).  The  observed  data  were  the  numbers  of  killed larvae within 24 hours. The data were analyzed using one way ANOVA which was continued by  Tukey HSD ( = 0,05). The result showed that PLI 1%, 1.5%, 2%, and 2.5% had very significantly different effects compared to the negative control (p=0.000), but there was no significantly different effect between PLI 2 % and temephos 1%. It is concluded that PLI  2% has a larvicide effect as strong as temephos does.  Keywords : Culex sp larvae, papaya’s leaves infusion, temephos
