Mango (Mangifera indica L.) is an important natural resource and also known as the 'king of fruits'. The districts of Murshidabad and Malda once famous for mango are now facing tremendous genetic erosion of the mango germplasm. More than 200 varieties of mango were recorded during the time of the royals of these districts. This number has sharply declined in recent times. The traditional varieties are low yielding and are replaced by new high yielding hybrids. These varieties are also facing extinction because of the aggressive cultivation of Amrapali, Chatterjee, Mallika, Himsagar, Langra varieties of mango. Hence, conservation of Mango (Mangifera indica L.) germplasm is of utmost importance. For such conservation extensive survey and proper documentation are necessary. In this context, the present study is an attempt to document the mango varieties from Murshidabad and Malda districts of West Bengal. The mango germplasm diversity data generated will be valuable to communities, scientists and policy managers to formulate and implement conservation strategies of in situ, on-farm as well as ex situ conservation and management of these genetic resources.Keywords

Freshwater lentic water bodies have tremendous importance as they contain valuable aqua resources, both flora and fauna. They are also the recharging reservoirs for drinking water, domestic use and provide the infrastructure for pisciculture. Hydrophytes are important components of lentic ecosystem. Aquatic plants provide shelter and breeding place for aquatic animals and maintain the integral balance of ecosystem. They are the primary producers and contribute dissolve oxygen (DO). All organisms, from the microscopic zooplankton to the fish need the oxygen for survival. Dissolved oxygen is one of the limiting factors for fish diversity in aquatic ecosystems. The present investigation is on the hydrophyte diversity in the freshwater lentic water body of Murshidabad, West Bengal. Rivers Bhagirathi and Jalangi and their tributaries flow through this district. Large number small and large freshwater lentic water-bodies are found in this district too. The survey of the composition and distribution of the hydrophytes in freshwater lentic water body of Murshidabad was carried out. A total of 53 species of aquatic plants were identified from different parts of the district. Of these, 41 species are found throughout the district whereas 12 species are restricted in some pockets of the district. The detailed distribution as well as habitat composition with GPS location was studied. The relationship of DO and the biodiversity components was explored.- Insect Inventories in a Mango-based Agroforestry Area in Murshidabad, West Bengal

Agroforestry is an eco-friendly crop production system that provides habitat for biodiverse flora and fauna. The mango-based agroforestry constitutes of mango trees, crops, weeds, insect pests, predators and pollinators. The mango (Mangifera indica L.) plant is a multipurpose fruit tree that yields fruit, timber and fuel, and is suitable for agro-forestry systems in tropical and subtropical regions. The mango fruit is an important source of sustenance for birds, bats, insects, and mammals. Many insect species damage mango crops by feeding on leaves, stems, flowers, and fruits. Also, many insect species play a vital role in pollination as well as fruit set, and predator prey interactions keep balance between pest incidence and fruit production. Insect species inventories along with pest prevalence and foraging behaviour of pollinators were investigated in several mango orchards of Murshidabad. Insects were collected by capture with sweep net and visual observation followed. The principal insect pest of mango were 2 species of hopper and 1 species of mealy bug, inflorescence midge, fruit fly, scale, shoot borer, leaf webber and stone weevil. The leaf hopper, shoot borer and stone weevil are found to be major pest in Murshidabad mango based agroforestry area.- Mango Field Gene Bank in Gurudas College, Kolkata, West Bengal
