Indigenous mango (Mangifera indica L.) varieties have unique aroma, taste, flavour, texture and size. The interactions among volatile compounds and with sugars and acids have a role in the distinct mango flavor. Murshidabad district of West Bengal has several indigenous mango varieties that have unique attributes like taste and aroma. The indigenous Champa mango variety of Murshidabad district has a distinct aroma very similar to that of the champaka flower (Michelia champaca L.). The present investigation was to determine if there was any phyto-chemical which could be responsible for the distinct and unique aroma present in the mango variety Champa. Eugenol, a phytogenic bioactive component frequently found in diversified herbal plants was found by GC-MS analysis of the methanolic extract of the fruit pulp of indigenous mango variety, Champa.

Rapid Urbanization

Given that urbanization is considered as one of the most signicant anthropogenic alteration of the overall environment, the present study attempts to understand spatial-temporal characteristics of urban population growth and its implications on land-use as well as understanding their relationship with environmental degradation with special focus on the Kolkata, the capital city of West Bengal. Urbanization is one of the major driving forces behind the development of today's land-use and land cover system. A large number of contemporary urbanization has been characterized as urban sprawl namely in an extensive form of land-use for urban uses that have environmentally detrimental effects. There are indications of Urban sprawl and city expansion in our Study Area of Kolkata indicating expansion of settlements and built-up area and thus causing environmental degradation in the city area. The process of urbanization always had signicant implications that can affect cumulative changes in demographic characteristics and/or transformation of the physical environment; unplanned, unsystematic and rapid urbanization can cause intense impacts on various environmental aspects, specically on land and air and water. A thorough understanding of the dynamic relationship between urbanization and its generated land-cover changes thus becomes completely essential for managing environmental changes and enabling sustainability of the environment and its resources.

Complementary Strategy

Many important varieties of field, horticultural and forestry species are conserved as Field Gene Banks (FGB). FGBs provide easy and ready access to conserved material for research as well as for use. Plant breeders are in need of a continuous supply of diverse and novel genetic diversity to produce new crop varieties able to cope with the impacts of changing cultivation conditions and climate change. FGB is one of the options of a complementary strategy for the conservation of germplasm of many plant species. Murshidabad and Malda, the once famous districts for Mango (Mangifera indica L.) diversity, districts of West Bengal are now facing tremendous genetic erosion of the mango germplasm. The Field gene bank will be an ex situ conservation approach. 25 (Twenty five) mango varieties were collected from Malda and Murshidabad districts and cuttings transferred to Gurudas College, Kolkata 700054 for conservation as Field Gene Bank. The mango germplasm accessions were collected with the assistance of the West Bengal Biodiversity Board (WBBB). Some of the valuable mango varieties viz. Bimli, Churmur, Dobani, Do Phala, Golap Bhog, Golap Khash, Molam Jam, collected from orchards of Malda and Murshidabad districts. As a field Gene Bank these varieties are readily accessible and useable for characterization and evaluation. These field gene banks will aid in documentation of the rich mango legacy of West Bengal and help in mango crop improvement.

Two new species, Diptilomiopus indogangeticus n. sp., infesting Ficus tinctoria subsp. gibbosa (Blume) Corner (Moraceae), and Diptilomiopus mohanasundarami n. sp., infesting Mangifera indica L. (Anacardiaceae), are described from West Bengal, India. Diptilomiopus holoptelus Chakrabarti and Mondal and Diptilomiopus strebli (Boczek) are possible junior synonyms of Diptilomiopus integrifoliae Mohanasundaram and Diptilomiopus asperis Ghosh and Chakrabarti, respectively.
