ABSTRACT The gut microbiota plays a vital role in nutrient and energy utilization, as well the host's ability to adapt its immune system environmental changes. As biological control agent for invasive Parthenium weed, beetle Zygogramma bicolorata ( Z. ) Pallister is often exposed fluctuating temperatures, which may induce stress natural habitat. This study utilized 16S amplicon sequencing explore impact of temperature on microbiome under cold (15°C), (27°C), hot (35°C) conditions. A total 11 bacterial phyla 149 genera were identified, with Firmicutes, Proteobacteria, Cyanobacteria being most abundant. Temperature treatments significantly influenced diversity microbiota, evidenced by alpha measures. Principal coordinate analysis further revealed substantial variations composition across different Additionally, PICRUSt2 suggested that linked metagenomic functions related amino acid carbohydrate transport, inorganic ion metabolism, cellular processes. Our findings suggest thermal alters beetles, offering new insights into how these beetles have ecologically adapted fluctuations, while also highlighting potential microbes maintaining health stress.
