IPM and Diseases of Litchi

Insect pests are the major biotic constraints in healthy litchi production apart from some abiotic stresses. Nearly 42 insect species and mite pests have been reported to attack litchi trees and fruits at different stages of growth and fruiting. Borers, bugs, leaf rollers, loopers, weevils and mites are the important group of pests affecting litchi production. Diseases are one of the constraints to the production of litchi fruits too. They indirectly reduce yield by debilitating trees, and directly reduce yield or quality of fruit before and after harvest. Most of the diseases are caused by fungal pathogens. Monitoring is one of the important tools to keep track of the pathogens and their potential damage. Knowledge about diagnostic symptoms of various diseases and their management practices are important.
