Banana is an important fruit crop in Cooch Behar district of West Bengal, India, located geographically at Teesta flood plain of Terai region. Banana comprises maximum areaof 1915 ha among all fruits grown in this district with the production of 35,480 MT and
productivity of 18.52 MT/ha.There is all time demand for this very fruit in the market, but market price of this fruit varies due to scar and blemishes on the fruit. The scar is developed by the attack
of scarring chrysomelidae beetle, Basilepta subcostatum Jacoby. The scarring beetle, B. subcostatum is a serious pest banana in the entire North-East India which causes about 19.3% damage of fruit yield. Attack of scarring beetle is aggravated by hot and humid weather which is a typical characteristic of weather in this region prevailing from April to October. Adult of the beetle feed on epidermis, i.e., the green portion of ventral and dorsal surface of the leaves and makes irregular patches. The beetle also attack on fruit causing heavy damage, fruits become blemished, and market
value is reduced. Keeping these aspects in mind, the present front line demonstration was conducted to assess the performance
of banana bunch cover in the context of present climatic vulnerability in this region
