BRIEF RESUME OF THE INTENDED WORK:
6.1 NEED FOR THE STUDY:

Insect-transmitted diseases remain a major source of illness and death worldwide. Mosquitoes alone transmit disease to more than 700 million people annually. Malaria alone kills 3 million each year, including 1 child every 30 seconds. Although mosquito-borne diseases currently represent a greater health problem in tropical and subtropical climates, no part of the world is immune to this risk1.

Control of such diseases is becoming increasingly difficult because of increasing resistance of mosquitoes to pesticides. An alternative approach for mosquito control is the use of natural products of plant origin. The botanical insecticides are generally pest specific, readily biodegradable and usually lack toxicity to higher animals. One plant species may possess substances with a wide range of activities, for example extracts from the neem tree Azadirachta indica showed antifeedant, oviposition deterrent, mosquito repellent and growth regulating activity.

In recent years interest in plant based products has been revived because of the development of cross-resistance and possible toxicity hazards associated with synthetic insecticides and their rising cost. Phytochemicals obtained from the huge diversity of plant species are important source for safe and biodegradable chemicals, which can be screened for mosquito repellent and insecticidal activities and tested for mammalian toxicity2.

In addition to application as general toxicants against mosquito immature, phytochemicals may also have potential uses as growth and reproduction inhibitors, repellents, and oviposition deterrents.

The most common mosquito repellent formulations available on the market contain DEET (N,N-diethyl-3-methylbenzamide), which has shown excellent repellency against mosquitoes and other biting insects .However, human toxicity reactions after the applications of DEET vary from mild to severe. To avoid these adverse effect, research on repellents that are derived from plant essential oil to replace DEET. Botanical repellents are promising in that they are effective, safe to users, and also inexpensive1.



A large number of such plants are available in ayurveda, which if validated scientifically helps a lot to the society. Hence the present study is proposed to investigate the LARVICIDAL ACTION OF ESSENTIAL OILS FROM THE FLOWERS OF NELUMBO NUCIFERA AND TAGETES ERECTA.

6.2 REVIEW OF THE LITERATURE:
NELUMBO NUCIFERA1
Synonym: Nelumbium nelumbo.

Family: Nelumbonaceae.

Description: Perennial aquatic herb, Root stock stout, cylindrical. Leaves peltate, radiately nerved. Flowers large, solitary, fragnant, ovoid, fleshy, sunk separately in cavities of receptacle, maturing into nut-like achenes.

Parts used: Root, leaves, flowers, seeds

Chemical constituents: Leaves contain alkaloids: nuciferine, roemerine, flavanoid: quercetin. The plumules yield proteins, sugars and vitamins. The receptacles contain quercetin.

Uses: Lotus is helpful in controlling the burning sensation, due to its cold potency. The leaf paste is applied to the body in case of fever and inflammatory skin conditions. The flower stalk, mixed with other herbs, is used to treat bleeding from the uterusons. The leaves are also used in treating sunstroke, diarrhea, dysentery, dizziness and vomiting of blood.
TAGETES ERECTA2

Synonym: Mexican marigold.

Family: Asteraceae

Description: Tagetes erecta is a bushy composite plant, having pinnate leaves and large yellow or orange flower heads. Also called Aztec marigold.

Parts used: Flowers, leaves, stem.

Chemical constituents: Tagetes erecta contains thiophenes, flavonoids, carotenoids, triterpenoids. Glucoside of Quercetagenin, phenolics, syringic acid, quercetin, thienyl and ethyl gallat.

Uses: The flowers of Tagetes erecta are the source of two food colourant products: Marigold meal and Marigold extract. The plant is most effective against the nematode species Pratylenchus penetrans. T. erecta is grown to extract lutein, a common yellow/orange food colour. The essential oil of the flower contains antioxidants.

will be used to obtain related information regarding this research protocol.
7.2 PLAN OF WORK:

The whole study is divided as:


PLANT COLLECTION AND EXTRACTION:

The plants Nelumbo nucifera (Nelumbonaceae) and Tagetes erecta (Asteraceae) will be collected from wild source and will be authentified. They will be subjected for steam distillation by using Clevenger’s apparatus. The concentrate extract will be useful for our studies.


METHODS:
LARVICIDAL ACTIVITY2:

The larvicidal activity of medicinal plants will be determined against Aedes aegypti and Anopheles stephensi urban mosquito vector after making serial dilutions5. 2,1,0.5,0.25 and 0.125% in acetone. Later 1 ml of the dilution will be made up to 250 ml with distilled water to obtain a final concentration ranging between 200 and 6.25 ppm. Four replicates will be used in the bioassays against 3 instar larvae of the three species along with concurrent controls. Mortality will be recorded after 24 h and percent corrected mortality will be determined by Abotts formula. LC 50 and LC 90 will be calculated.
