| Summary: | Background:
Dengue is the most mosquitoes borne viral disease of
human, frequently in subtropics and tropical countries.
Dengue occurs as dengue fever or dengue hemorrhagic fever
(DF/DHF). It is caused by a virus and transmitted by Ae.
aegypti mosquito. Pandanus amaryllifolius Roxb is a plant
which belongs to the family Pandanaceae. Pandanus
amaryllifolius Roxb had been reported to be used as an
insecticide before. The investigation is to be done is
therefore designed to prove the effects of methanol
extract of P. amaryllifolius R. leaves specifically
against Aedes aegypti.
Aims:
To proven that Pandanus amaryllifolius Roxb leaves
have a larvicidal effect against Aedes aegypti and to
know the LC50 and LC90 of methanol extract from Pandanus
amaryllifolius Roxb leaves against Aedes aegypti.
Methods:
It Performed by using methanol extract from Pandanus
amaryllifolius Roxb leaves against Aedes aegypti larvae.
Third and fourth larvae stage were used, with different
variation dosage after 24 hours of exposure and under
standard condition in laboratory.
Results:
LC50 of methanol extract from Pandanus amaryllifolius
Roxb�s leaves is 1733.94 ppm while LC90 is reported at
7000.01 ppm.
Conclusions:
In laboratory setting, the methanol extract of
Pandanus amaryllifolius Roxb leaves have larvicidal
effect against Aedes aegypti. From the probit graph the
increase of dosage concentration of extract also saw a
linear increase in the mortality of the larvae. |
