Dengue Hemorrhagic Fever
(DHF) is a disease caused by virus through Aedesaegypti mosquitoes as
the vector. The disease is spreading across the world andendanger and
threaten human life. Measures in controlling the vector using the
commonlarvaside “abate” are in adequate and less affective. The
objectives of the research is tofind out larvaside extracted from three
kinds of ascidian. The each ascidians (Polycarpaaurata, Didemnum molle
and Rophalaea crassa) were extracted with ethanol, and thecrude extracts
were subjected to larvasidal test by dissolving in water containing
thelarvae. The remarkable extract activity was partition in ethyl
acetate, hexane andbuthanol. The results show that extract of Polycarpa
aurata has the highest activity. Theactivity of fractions show that
ethyl acetate at 100 ppm reveals the highest mortality oflarvae 100% in 8
hours, followed by hexane fraction (12 hours) then buthanol fraction
(18hours). All the fractions (Ethyl acetate, Hexane and Buthanol) could
totality kill the larvaewithin 24 hours which is comparable to the
abate.
