West Bengal, IndiaA survey had been conducted in districts of South 24 parganas, Nadia, Barddhaman and Jalpaiguri of West Bengal, India on shoot fly infestation of bamboo. Acroceratitis parastriata David & Hancock, Rioxoptilona dunlopi (Wulp) (Diptera: Tephritidae) and Neosilba sp. (Diptera: Lonchaeidae) a saprophytic species could be recorded on young shoots of bamboo. Amongst the infesting species, Acroceratitis parastriata David & Hancock had been found to be predominant. Infestation of the pests caused severe damage of newly emerged shoots of the crop, resulting in oozing, stunted growth with hollow internode and drying up of the entire shoots. The activity of the flies could be recorded during day. Maximum pest attack took place when bamboo shoots were of 15-20 cm height. The extent of damage ranged from 35.27 -55.42 %. All the species could be recorded form the infested samples of Bambusa tulda collected from districts of South 24 pgs, Bardhaman and Nadia; only Acroceratitis parastriata was recorded from infested samples of Bambusa balcooa (Roxb) collected from district of Jalpaiguri. This is the first report of dipteran shoot fly infestation on bamboo from West Bengal.
