520 _aBamboo (Poaceae) is a tall, arborescent grass which is called as ‘Green gold’ owing to its versatile uses, ecological significance, etc. Bamboo-shoot fruit fly breed and feed in the newly developed bamboo shoots, causing damage and disrupting normal growth of bamboo. Two groups of Tephritidae are known to be associated with bamboo in the oriental region: Gastrozonini (Dacinae) and Acanthonevrini (Phytalmiinae). The present study was carried out from July, 2023 to June, 2024 at four locations (Bhoirymbong, Umeit, Umtrew and Kyrdemkulai) in the Ri-Bhoi district of Meghalaya to understand the diversity, richness, and abundance of the bamboo-shoot fruit fly. For sampling, two different methods: food baits and active searching were used. A total of 13 different bamboo-shoot fruit fly species were recorded belonging to 10 genera (Genus Acrotaeniostola, Acroceratits, Chaetellipsis, Gastrozona, Paraxarnuta and Xanthorrachis of tribe Gastrozonini; Genus Ptilona, Rioxoptilona, Themara and Erectovena of tribe Acanthonevrini). Two unidentified bamboo-shoot fruit fly species were also recorded each from Umeit and Bhoirymbong. Among the 13 different species; 6 species were recorded for the first time in Meghalaya and one species (Chaetellipsis alternata) in India. Rioxoptilona dunlopi (287) was the most dominant species in all the four experimental locations while the least was Acrotaeniostola apiventris (14). Among all the locations, Umeit recorded the highest number of species (523) followed by Bhoirymbong (295), Kyrdemkulai (199) and Umtrew (150). Biology of Gastrozona soror was studied under laboratory condition to understand the different biological parameters of the species. The highest and lowest Margalef’s D index was observed in the month of September and January respectively, at Bhoirymbong. Whereas, Shannon-Weiner index highest value of 2.285 was observed in the month of June and the lowest value of 0.636 in the month of December, January and February. Pielou’s evenness index was highest during April and November at Kyrdemkulai and the lowest was during January at Umeit. Beta diversity indices viz., Jaccard (0.769) and Sorenson (0.869) were observed to be relatively low, which indicated similarity in both the locations. In PC analysis, the maximum and minimum eigenvalue were 1.81 for PC1 and 0.17 for PC2. Cluster analysis was carried out to understand the fly population and its association with habitat specific occurrence. The Correlation analysis (p=0.05) showed that the population of flies had a significant positive correlation with relative humidity for Umiam and Kyrdemkulai. Also, in Kyrdemkulai, population of bamboo-shoot fruit flies had a positively significant correlation with maximum temperature but negatively significant correlation with minimum temperature. This study will provide a data base for the future quarantine and taxonomic study
