| Summary: | Dengue Fever (DF) and Dengue Haemorrhagic Fever
DHF), is one of the major health problem afflicting
Indonesia. Dengue Fever (DF) is caused by an arthropodbourne
virus of the genus Flavavirus, within the family
Flavaviridae, which is transmitted through the bite of
female
Aedes aegypti
mosquitoe. Elimination of vector
can be done by environmental management, biological
control, chemical control (WHO, 2004). Various research
and experiment done shows that
Pandanus amaryllifolius
Roxb.
leaves contain several compounds that can be used
as natural insecticide. Previous study has
demonstratedIt is containing poliphenol, flavanoid,
saponin, volatile oil, and alkaloid.
Aim of study:
To determine whether there is larvicidal effect of
chloroform extract of pandan leaves (
P.
Amaryllifolius)
againts
Ae. aegypti
larvae and the effective
concentration of LC50 and LC90 of the extract, and also
to establish whether an increase in concentration of
thr extract cause an increase in the mortality of
larvae.
Method:
The test is performed by introducing a set amount
of chloroform extract of
P. amaryllifolius
leaves
against
Ae. aegypti
larvae of the 3
rd
and 4
th
instar,
with variation of concentration, under standarized
bioassay methods.
Result:
The LC50 and LC90 of chloroform extract of
P.
amaryllifolius
leaves against
Ae. aegypti
larvae is
221.67 ppm and 855.58 ppm, respectively.
Conclusion:
There is larvicidal effect of chloroform extract
of pandan leaves (
P. amaryllifolius
Roxb.) againts
Ae.
aegypti
larvae and with LC50 is 221.67 ppm and LC90
855.58 ppm. An increase in concentration of the extract
cause an increase in the mortality of larvae.
