Abstract

Lac insect – host plant interaction: practical implications Synergistic system of insect plant interaction has been exploited for many purposes. The interaction whether herbivory or insectplant mutualism including pollination are best understood only when the implications of biochemical events and its physiological role is understood. The concept becomes more important when the interaction results in an economic gain for the mankind. Many currently available pharmaceuticals including opium, aspirin, cocaine, and atropine are derived from the secondary metabolites of plants which are used to protect themselves from herbivores. The concept of biological control agents in pest control wherein use of repellent companion planting, defensive live fencing, and ‘obstructive-repellent’ interplanting are making use of those compounds synthesised by plants as a defensive measures to act against its insect counterpart.
