abstract
Insects belong to order Lepidoptera include moths, comprising approximately 1,60,000 species acts as a major crop pest of the world. Many insects play as host to different microbes by forming close mutualistic relationships. The study on this topic reveals bacterial symbiont play important role on host’s biology, it may impact on host’s digestion, immunity, anti-pathogenic responses, nutrient absorption of host food etc.; Fruit piercing moths are common agricultural pest which damages the commercially important fruit crops such as moth of genus Othreis as a harmful pest on pomegranate, citrus and orange mostly found in Maharashtra state. Most of the moth vertically transmit the endosymbiotic microorganisms, which can affect the host in different parameters like fitness, reproduction, genetic diversity etc. according to study of genome sequencing of Erebidae moths focusing on bacterium Wolbachia. Different life stages like egg, larva, pupa, adult, varies in their gut microbiota. This review reveals the work done on the diversity and richness of gut microbiota, their role on host fruit piercing moth, in Maharashtra, India and different countries of world.
