Bacterial communities associated with the gut of tomato fruit borer, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) based on Illumina Next-Generation Sequencing
TLDR
The search on function of different gut inhabiting bacteria of H. armigera revealed their role in nutrition, detoxification of lethal insecticide molecules, and defensive action against pathogens.Abstract:
Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae), a polyphagous agricultural pest of global importance, harbour diverse bacterial communities in its gut. We analysed the composition and diversity of gut bacteria using Illumina Next-Generation Sequencing of 16S ribosomal RNA amplicons. The data set consisted of 864,813 high-quality paired end sequences with mean length of 150 base pairs. Highly diverse bacterial communities were present in the sample containing approximately 2303 operational taxonomic units (OTUs). A total of 17 bacterial phyla, 34 classes, 84 orders, 173 families, 334 genera, and 707 species were identified from the sequence analysis. Actinobacteria was the most dominant groups, followed by Proteobacteria and Firmicutes . The search on function of different gut inhabiting bacteria of H. armigera revealed their role in nutrition, detoxification of lethal insecticide molecules, and defensive action against pathogens. Insecticidal toxin producing bacterial species were also found associated with the H. armigera gut .read more

Metagenomic and functional analysis of hindgut microbiota of a wood-feeding higher termite
TL;DR: A metagenomic analysis of the bacterial community resident in the hindgut paunch of a wood-feeding ‘higher’ Nasutitermes species shows the presence of a large, diverse set of bacterial genes for cellulose and xylan hydrolysis, the first system-wide gene analysis of a microbial community specialized towards plant lignocellulose degradation.

Annotation of gut bacterial taxonomic and functional diversity in Spodoptera litura and Spilosoma obliqua.
TL;DR: The significance of the inherent microbiome of two defoliators in shaping the metagenome for nutrition and detoxifying the chemical molecules is highlighted, and an avenue for exploring role of insect gut bacteria in host selection, metabolic endurance of insecticides and synergistic or agonistic mechanisms inside gut of insects feeding on insect‐resistant biotech crops is opened.
