This book is an outcome of hard work done during the compilation of my M.Phil. degree at CSR&TI, Pampore, Kashmir, India. It contains a piece of useful information for the researchers who are engaged in the development of Sericultural Industry. This study will be very useful to the farmers in all areas were a major insect or non-insect pests are appearing year after year and causing serious damage to Mulberry foliage. It will also help in developing an integrated pest management programme for the said mites so that their damage to mulberry foliage could be controlled and we may be able to get good quality of leaf which will indirectly provide us better quantity and quality of silk.
