Review of Literature
Literature on various aspects of the utilization of botanicals in the management of
selected culicine larvae pertaining to the present investigation is reviewed.
Use of larvicides, dates back to as early as 1899, when Sir Ronald Ross
applied kerosene on anopheline larval breeding sites in Sierra Leone, West Africa
was an approach with great potential for malaria control (Bockarie et al.,
1999;Kileen et al., 2002). Toxicity of phytochemicals to mosquitoes was first
reported by Campbell et al. (1933). They have also evaluated the relative toxicity of
nicotine, nabasine, methylanabasine and lupine for culicine mosquito larvae.
Watson (1941) reported the effect of antimalarial oil against mosquito larvae.
Toxicity of rotenone extracted from indigenous Derris roots to mosquito larvae was
investigated by Ameen et al. (1983).
Toxicity of natural essential oils to mosquitoes, Aedes aegypti L. and
Culex fatigans Wiedemann (syn. Culex quinquefasciatus Say) was investigated by
Sharma et al. (1994). Perich et al. (1994) demonstrated the toxicity of extracts of
three species of Tagetes against adults and larvae of yellow fever mosquito and
Anopheles stephensi Liston. (Diptera: Culicidae). Sharma and Saxena (1994)
studied the phytotoxicological potential of Tagetes erectes L. extract on aquatic
stages of An. stephensi. Das et al. (1996) studied the toxicity of some alkaloids on
the larvae of Culex quinquefasciatus Say. Azmi et al. (1998) evaluated the toxicity
of neem leaf extract (NLX) and compared the same with that of malathion (57 E.C.)
against late third instar larvae of Cx. fatigans (wild strain) by the WHO method.

plant extracts (Azadirachta indica A. Juss, Rhazya stricta Decne and Syzygium
aromaticum L. Merrill and Perry) on Culex pipiens larvae (Diptera: Culicidae).
Differential toxicity of leaf litter to dipteran has been worked out by David et al.
(2000). Anyaele and Amusan (2003) highlighted the toxicity of hexanolic extract of
Dennettia tripetala G. Baxer to the larvae of Ae. aegypti. Toxicity of the latex of

active compounds â- Caryophyllene, germacrene D, Camphor, Artemisia ketone, 1-8
Cineole, D-Copaene and Sabinyl acetae.
Efficacy of bioactive compounds from Curcuma aromatica Salisb. against
mosquito larvae was described by Madhu et al. (2010). Phytochemicals of the leaf
extracts of Pedilanthus tithymaloides L. (Family: Euphorbiaceae) were found
to be toxic to the filariasis vector Cx. quinquefasciatus (Diptera: Culicidae)
(Kamalakannan et al., 2010).
Biological Studies
Botanicals that are tested against the life stages of the mosquitoes have a profound
effect on the developmental period, growth, adult emergence, fecundity, fertility and
egg hatchability. Several studies have been carried out by various researchers to
assess the impact of plant products in the life stages of mosquitoes.
Maradufu et al. (1978) reported the isolation of (5E)-ocimenone, a mosquito
larvicide, from Tagetes minuta L. Effects of certain essential oils on mortality and
metamorphosis of Ae. aegypti were reported by Osmani and Sighamony (1980).
Arnason et al. (1981) analysed the mosquito larvicidal activity of polyacetylenes
from certain species of the family Asteraceae. Some components and their properties
of the neem tree (A. indica) and their use in pest control in developing countries
were assessed by Schmutterer (1981). Kalyanasundaram and Babu (1982) described
the biologically active extract of the plant, Cleome viscose L. as a mosquito
larvicide. Saxena and Yadav (1983) evaluated the extract of Oligochaeta ramose
Roxb. Wagenitz (Family:Compositae) to suppress the population of the yellow fever
and dengue vector Ae. aegypti (Diptera: Culicidae).

Studies on the larvicidal properties of Nerium indicum Mill. (Apocynaceae)
leaves were carried out by Chavan and Nikam (1983). More than 2,000 plant species
have been known to produce chemical factors and metabolites of value in pest
control programmes (Ahmed et al., 1983). Zebitz (1984) suggested that azadirachtin
acts as an antiecdysteroid and thus kills the larvae by inhibiting their growth. Effects
of Melia azadirachta L. extracts on many insects have been reported by various
investigators (Saxena et al., 1984; Schmidt et al., 1998; Juan et al., 2000; Carpinella
et al., 2003; Nathan and Saehoon, 2005). The effect of crude methanolic extracts of
Ajuga spp. on postembryonic development of different mosquito species was
observed by Marcard et al. (1986).
Laboratory studies of some plant extracts as mosquito larvicides were
reported by Qureshi et al. (1986). Indigenous plant oils were evaluated for their
larvicidal potential against An. stephensi (Kumar and Dutta, 1987). Evaluation of
Melia volkensii Gurke extract fractions as mosquito larvicides was done by Mwangi
and Mukiama (1988). Growth-inhibiting and larvicidal effects of M. volkensii
extracts on Ae. aegypti larvae were suggested by Mwangi and Rembold (1988).

fluviatilis (Lutz) (Diptera: Culicidae) in the laboratory was reported by Consoli et al.
(1989). Mosquito larvicidal and ovipositional activity of Descurania sophia (L.)

extracts upon Cx. pipiens larvae. Chockalingam et al. (1990) analysed the larvicidal
activity of different plant products against mosquito larvae.

et al., 1995; Batra et al., 1998). Sharma (1996) assessed the ovicidal and growth-
disrupting activity of Sphaeranthus indicus Linn extract against the filariasis vector,
Cx. quinquefasciatus. Dhar et al. (1996) demonstrated the effect of neem oil
volatiles on the gonotropic cycle and inhibition of oviposition in An. stephensi and

Fruit extracts of Melia azadirachta Linn. exhibit a variety of effects in

disorders, morphogenetic defects and changes in behaviour (Schmidt et al., 1998;
Gajmer et al., 2002; Banchio et al., 2003; Wandscheer et al., 2004). Moawed (1998)
compared the combined action of some plant extracts against Cx. pipiens larvae and
their physiological impact.
Various investigators have reported that the members of the family
Meliaceae are known to contain a variety of compounds, which show insecticidal,
antifeedant, growth-regulating and development-modifying properties (Nugroho
et al., 1999; Greger et al., 2001; D’Ambrosio and Guerriero, 2002; Nakatani et al.,
2004). Mulla and Su (1999) found out that neem contains atleast 35 biologically
active principles, of which azadirachtin (AZA), a triterpenoid, is the predominant
insecticidal active ingredient in the seeds, leaves and other parts of the neem plants.
Azadirachtin and other ingredients were shown antifeedant, sterility-inducing and
larvicidal action against insects.
