Surveillance, Screening and Estimation of Yield Losses

The thesis book Ph.D. (Ag. Entomology) 2017, the author has provided a sufficiently critical evolution from which one can deduce that work can potentially produce a significant contribution to the subject area. Litchi is a highly priced, popular and major table fruit in Chhattisgarh. It comes to market in the months of May-June when the market is full of other fresh fruits, particularly mango and jackfruit. But in spite of the availability of different types of fruit in the market the demand for fresh litchi is always very high due to its unique taste, flavor and colour. The study was undertaken to know the surveillance, screening and estimation of yield losses due to major insect pests on litchi genotypes in northern hill region of Chhattisgarh. The book is divided into seven parts each part dealing with separate aspects and all these parts have been presented in a logical sequence.
