(Kabilan et al., 2005). Much isolation of all the four
serotypes of dengue virus (DENV) was made from
pools of
Ae. aegypti
; for the first time DEN1 and
DEN4 (five isolates) in 1961 (Carey et al., 1964) and
DEN2 (two isolates) in 1966 (Myers et al., 1966) and
36 isolates of all the four serotypes in 1968. During
that time there was no much breeding of
Aedes
species.

So dengue fever was absent. Subsequently, with the
introduction of piped water supply, storage facility,
etc., dengue made incursions to rural areas of south
India and outbreaks have been reported (Abdul, 1997).
In rural areas of India, the role of
Ae. aegypti
as a
principal vector had already been well documented
(Ilkal & Dhanda, 1991).
Ae. albopictus
also has been
considered a potential vector of dengue and several
virus isolations have been made in southeast Asia
(Hawley, 1988).
Vector control has been the main program to control
the communicable diseases. However, continuous and
indiscriminate use of pesticides for public health or
agriculture purpose, has posed serious problems such
as development of insecticide resistance by vectors
and pests. Various attempts to overcome this problem
have lead to the discovery of more potent insecticides.
Among these, synthetic pyrethroids are playing a
major role because of their high efficacy, low
mammalian toxicity and photostable nature with a
