INTRODUCTION: 

INTRODUCTION Belong to order Isoptera . Live in colonies. About 4000 species of termites are estimated. 10% of which are damaging. Commonly known as white ants. Termites mostly feed on dead plant materials. Most important economically important wood destroying pest in the world Termites are often called the "silent destroyer". 4 “TERMITES AS INSECT PEST OF RANGELAND & FOREST”

DAMAGE: 

11 DAMAGE Termites feed upon old roots, tree stumps, fallen tree limbs and branches on the ground, and similar materials. Occasionally termites attack living plants, including the roots of shrubs and trees Odontotermes and Microtermes , occur in young, exotic trees such as Eucalyptus in dry regions in Africa and India Termites occasionally attack healthy trees and shrubs, but they prefer trees and shrubs already in a declining state of health. “TERMITES AS INSECT PEST OF RANGELAND & FOREST”

PLANT DEFENCES AGAINST TERMITES: 

12 PLANT DEFENCES AGAINST TERMITES Many plants have developed effective defences against termites. Defence is typically achieved by secreting anti- feedant chemicals (such as oils, resins, and lignins ) into the woody cell walls. This reduces the ability of termites to efficiently digest “TERMITES AS INSECT PEST OF RANGELAND & FOREST”
