Sesamia inferens (W.) is polyphagous agricultural pests and prevalent in the India, China, South Asia and South East Asia. Insecticides is not recommended because, apart from the hazardous effects of chemicals, its larvae tunnel throughout the stem from first instar. Associated bacteria with insects provide several benefits to their host, revealing the types of bacteria associated with S. infersns will give basic information, which may throw light on management of this noxious pest. The culture dependant, 16S rRNA gene technique revealed thirty two bacterial isolates from gut of S. inferens from different region of India and host, comprising phyla Proteobacteria, Firmicutes and Bacteroidetes. Among which proteobacteria phyla was dominant with families and genus like Enterobacteriaceae (Citrobacter, Enterobacter, Serratia, Klebsiella and Xenorhabdus), Pseudomonadaceae (Pseudomans), Moraxellaceae (Acinetobactor) and Comamonadaceae (Comamonas). The phyla Firmicutes less dominant with four families and one genus each viz., Staphylococcaceae (Staphylococcus), Bacillaceae (Lysinibacillus), Streptococcaceae (Lactococcus) and Enterococcaceae (Enterococcus). Third phyla had only one family viz., Flavobacteriaceae (Chryseobacterium). The bacterial diversity varied greatly among insects that were from different host plants than those from the same host plant of different locations. This result suggested that the type of host plant greatly influences the mid-gut bacterial diversity more than the location of the host plant of S.inferens. These bacterial populations may have a key role in digestion, as well as other benefits to the S. inferens larvae. Determination of the bacterial community and its biological functions within the insect could provide us with basic information for future pest control research.
