Abstract
In the increasing globalisation era, movement of goods and planting materials between countries being carried out at ease, are potential factors of introduction of invasive alien insects, diseases, and weeds in India. Infested fruits carried by international travellers, cargo / sea shipments of wood logs, food trade, and accidental introduction through air travels were the potential ways of entry of invasive alien insects into any country. The entry of alien invasive pest causes huge economic damage by way of direct crop loss. In addition, the panic situation to save the crops results in indiscriminate use of chemical insecticides that is harmful to applicator, farmer and consumer. Frequent application of insecticides leads to reduction in natural enemies and pollinators there by having an adverse impact on the ecosystem. The present paper critically reviewes the existing plant quarantine regulations in India, recent invasive and migratory insect pest problems and way forwards to safeguard Indian Agriculture.
