The Triatominae subfamily (Reduviidae) harbors some hematophagous insect species that have been firmly connected to the transmission of Trypanosoma cruzi , causative agent Chagas disease. Triatomines not only host and transmit trypanosomatids, but also coexist with a variety symbiotic microorganisms generally reside in insect’s intestinal flora. microbiome has profound effects on physiology, immunity, fitness survival animals plants. interaction between triatomines bacteria investigated extent revealed important symbionts. In contrast, range viral can infect triatomine insects is almost completely unknown. cases, genomic metatranscriptomic approaches uncovered sequences related possible genomes, but, date, eight positive single-strand RNA viruses, namely Triatoma virus Rhodnius prolixus viruses 1 - 7 more detail. Here, we review literature available viruses-insect relationship. lack broader metagenomic studies these medically relevant underscores importance expanding our knowledge virome both for surveillance purposes as well possibly harness their potential vector population control strategies.
