The adults and nymphs of Bemisia tabaci (Gennadius) were collected on tomato crop from different locations during 2021-2023. Bacterial colonies were isolated from adults and nymphs of B. tabaci using spread-plate technique and identified through 16srRNA sequencing. Nymphs showed high (55%) abundance of bacteria than adults (45%). 63.64% of the bacterial population in the nymphs belong to the phylum Bacillota followed by pseudomonadota (36.36%). In adults, Bacillota found dominant (100%). The class bacilli were dominant in both nymphs and adults (63.64 and 100% respectively). In the nymphal stage Bacillales was dominant order (54.55%). Similarly, in adults also Bacillales was found dominant (77.79%). Bacillaceae was abundant in nymphs (45.45%) and in adults same family accounted for 66.67%. The genus Bacillus was dominant in both nymphs (45.45%) and adults (55.55%). The species, B. licheniformis, B. pumilus, B. safensis and Staphylococcus saprophyticus were found common between adults and nymphs.
