Usage of synthetic pesticides to control pests has a number of disadvantages. Many phytochemicals possess antifeedant, grain protectant activities and act as effective pesticides. Administration of phytochemicals as viable alternatives to pesticides is suggested.

Entomologia Agraria, Via de Nicola, 07100 Sassari, Italy) Recent Studies on Essential Oils Formulations Used for Control of Insect Pests of Cultivated Plants. In: Crop Improvement, Production Technology, Trade and Commerce, V. 5, p 16 (Ref 66).

Wide range investigations of essential oils useful in the control of the phytophagous insects have demonstrated and enormous progress in the field. Their actions could be attributed to the interference with metabolic, biochemical, physiological, and behavioral functions of insects. Earlier evaluations have established their activity as ovicides, fumigants, and contact toxicants. Some essential oils exhibit acute toxicity, whereas other are attractive or repellents, antifeedants or affect on growth and development or reproduction. In the last ten years, great advances have been made in laboratory and field studies about use of the essential oils for the control of many insect pests. Activity, mechanism of action and useful formulations are discussed for the following insect orders: Diptera, Lepidoptera, Coleoptera, Orthoptera, Isoptera, Hymenoptera and Homoptera. In particular, the problems related to the volatility of the oils and their poor solubility in water have been discussed for an optimal application in field.

Indian subcontinent is endowed with varied agroclimates and topography. Therefore, it is one of the richest plant biodiversity of the world and rightly acclaimed as ‘Botanical garden of the world’. Among the ancient civilizations, Indian subcontinent has been known to be a rich repository of medicinal plants. The Rigveda (5000 B.C.) mentioned 67 medicinal plants, Yajurveda 81 and Atharvaveda (4500-2500 B.C.) 290 species. Charak Samhita (700 B.C.) and Sushruta Samhita (200 B.C.) have described properties and uses of 1,100 and 1,270 plants, respectively, in compounding of drugs and these are still used in classical formulations in the Ayurvedic system of medicine. Unani and Sidha system of medicines also utilize number of plants for medicinal purpose. Medicinal plants yield variety of complex chemical substances including glycosides, alkaloides and essential oils. The current worldwide trend towards the utilization of these natural plant products has created an enormous need for information about the properties and uses of these plants. Progress in medicinal plants research has undergone a phenomenal growth during the last couple of decades. Drugs therapy based on traditional system of medicine employing herbs forms a major therapy because of its no sideeffects. India accounts for 8% global biodiversity which exists in 2.4% land area of the world.
