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.

    The River Chambal is a principal tributary of the river Yamuna, supports a rich fauna and flora including the Ganges River dolphin, Gharial,Mugger, turtles and wetland birds. The Ganges River dolphin (Platanista gangetica gangetica),locally known as Susu, is restricted to the Ganga, Brahamputra, Karnaphuli-Sangu and Meghna river systems and their tributaries. Once believed to be in tens of thousands, their numbers have gradually reduced to 1800-2000 individuals in all the tributaries of its distribution. The subspecies is facing a series of threats to its survival including poaching,habitat destruction and incidental catches in gill nets. Information on the effects of anthropogenic pressure on dolphin distribution is either scanty or completely lacking, and thus are an impediment to effectively understand the conservation needs of the species.
