Introduction
Background of the Study
The Neem tree (Azadirachta indica) is a tropical evergreen tree native to India and is also found in other southeast countries. In India, neem is known as “the village pharmacy” because of its healing versatility, and it has been used in Ayurvedic medicine for more than 4,000 years due to its medicinal properties. Neem is also called ‘arista’ in Sanskrit- a word that means ‘perfect, complete and imperishable’. The seeds, bark and leaves contain compounds with proven antiseptic, antiviral, antipyretic, anti-inflammatory, anti-ulcer and antifungal uses. The Sanskrit name ‘nimba’ comes from the term ‘nimbati syasthyamdadati’ which means ‘to give good health’.
Termites are a group of eusocial insects that mostly feed on dead plant material, generally in the form of wood, leaf litter, soil, or animal dung, and about 10% of the estimated 4,000 species (about 2,600 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests. As eusocial insects, termites live in colonies that, at maturity, number from several hundred to several million individuals. Colonies use decentralized, self-organized systems of activity guided by swarm intelligence which exploit food sources and environments unavailable to any single insect acting alone. A typical colony contains nymphs (semimature young), workers, soldiers, and reproductive individuals of both sexes, sometimes containing several egg-laying queens.Many
