Dengue haemorrhagie fever
is one of the disease which caused by dengue virus. It spreads out by
mosquito Aedes aegypti as the vector. To date, people use abate as the
larvacidal. Yet it causes the negative effects, such as bad odor,
rustiness of the water container and resistency either to the larvae or
to the living environment if continue using it. The objective of the
research was to examine the larvacidal activity of Didemnum molle
extract against A. aegypti larvae. The sample was extracted with
methanol to give methanolic extract which was further partitioned with
ethyl acetate, hexane, and chloroform to yield three fractions of ethyl
acetate, hexane, and chloroform. Methanolic extract and the three
fractions were tested against the A. aegypti larvae instar III for
several concentrations. Abate and tap water were used as controls. The
result exhibited that Didemnum molle extracts contain or produce
larvacidae substances against A. aegypti larvae. They are approved by
the data of methanolic extract and the 3 fractions which are more
powerful than abate, particularly hexane. However it still needs to be
purified to obtain single active compound.
