Introduction
Mosquitoes are the major vector for the transmission of
malaria, dengue fever, yellow fever, filariasis, schistosomiasis, and Japanese encephalitis (James 1992; Gubler 1998).
Mosquitoes also cause allergic responses that include local
skin and systemic reactions such as angioedema in humans
(Peng et al. 1999). The yellow fever mosquitoes, Aedes
aegypti, is responsible for dengue fever in India where the
number of dengue fever cases has increased significantly in
recent years. Dengue viruses occur as four antigenically
related but distinct serotypes, which cause a broad range of
disease, including clinically asymptomatic forms, classic
dengue fever, and the more severe forms such as dengue
hemorrhagic fever–dengue shock syndrome (Fundacaõ
Nacional de Saú de 2002). Dengue is present in more than
100 countries and threatens the health of approximately 2.5
billion people. Worldwide, around 80 million people are
infected annually at an attack rate of 4% (Monath 1994).
Culex quinquefasciatus, a vector of lymphatic filariasis, is a
widely distributed tropical diseases with around 120 million
people infected worldwide and 44 million people having
common chronic manifestation (Bernhard et al. 2003).
Control of the mosquito larvae is frequently dependent
on continued applications of organophosphates and insect
growth regulators (Yang et al. 2002). An obvious method
for the control of mosquito-borne diseases is the use of
insecticides, and many synthetic agents have been developed and employed in the field with considerable success.
However, one major drawback with the use of chemical
insecticides is that they are non-selective and could be
harmful to other organisms in the environment. It has also
provoked undesirable effects, including toxicity to nontarget organisms, and fostered environmental and human
health concerns (Lee et al. 2001). The toxicity problem,
together with the growing incidence of insect resistance,
has called attention to the need for novel insecticides
(Macedo et al. 1997) and for more detailed studies of
naturally occurring insecticides (Ansari et al. 2000). These
