This book is useful for plant protection scientists by knowing peak period of major pests of tomato and managing the pest accordingly. Because nowadays, tomato faces severe yield loss cause by different pests of India and major pests of tomato are leaf miner, fruit borer and whitefly which cause more than 50 percent yield loss. To avoid the yield losses caused by these destructive pest and encourage cultivation as well as to increase the production and productivity of tomato, our efforts are needed to tackle these pests by knowing the peak period of infestation in relation to the weather parameters, effective insecticides against these pest and knowing the residual effect of used chemical insecticides in field condition. Looking to the above facts in view, a research theme was undertaken as population dynamics and management of leaf miner, fruit borer and whitefly on tomato.
