A Checklist of Iranian Cockroaches (Blattodea) with Description of Polyphaga sp as a New Species in Iran.

ABSTRACT: BACKGROUND:Cockroaches are of vital importance medically and hygienically. They are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. Cockroaches belong to the phylum Arthropoda, class Insecta, and order Blattodea or Blattaria. To date, over 4,500 cockroach species have been reported from different parts of the world. We overviewed the documents involved Iranian cockroaches to up-to-date checklist of cockroach species distributed in various provinces of Iran. METHODS:An extensive literature review was performed in 2013 on Iranian handbooks, reports and published data available since 1986 to obtain a comprehensive list of Iranian cockroaches. Furthermore, in an entomological survey in Tehran, cockroach specimens were collected and identified based on morphological and the DNA sequences of the mitochondrial cytochrome oxidase subunit II (COII) gene (mt-DNA COII) characteristics. RESULTS:Morphological characterization revealed presence of an un-described species very similar to Polyphaga aegyptiaca, P. indica and somehow to Pycnoscelus surinamensis, however, supplementary molecular analysis revealed the species was associated with Polyphaga of Corydiidae (Polyphagidae). With regards to the report of the un-described species, the cockroach fauna of Iran includes three families, 14 genera, and 26 species. CONCLUSION:Some species has not been collected or reported recently and also many geographical regions of the country have not been studied yet, hence a systematic research is required to reveal the real cockroach list of the country. Geographical distributions, nomination changes, and synonyms of cockroach species are presented.

Project description:The gut microbiome is shaped by both host diet and host phylogeny. However, separating the relative influence of these two factors over long periods of evolutionary time is often difficult. We conducted a 16S rRNA gene amplicon-based survey of the gut microbiome from 237 individuals and 19 species of omnivorous cockroaches from the order Blattodea. The order Blattodea represents an ancient lineage of insects that emerged over 300 million years ago, have a diverse gut microbiota, and have a typically gregarious lifestyle. All cockroaches shared a broadly similar gut microbiota, with 66 microbial families present across all species and 13 present in every individual examined. Although our network analysis of the cockroach gut microbiome showed a large amount of connectivity, we demonstrated that gut microbiota cluster strongly by host species. We conducted follow-up tests to determine if cockroaches exhibit phylosymbiosis, or the tendency of host-associated microbial communities to parallel the phylogeny of related host species. Across the full data set, gut microbial community similarity was not found to correlate with host phylogenetic distance. However, a weak but significant phylosymbiotic signature was observed using the matching cluster metric, which allows for localized changes within a phylogenetic tree that are more likely to occur over long evolutionary distances. This finding suggests that host phylogeny plays a large role in structuring the cockroach gut microbiome over shorter evolutionary distances and a weak but significant role in shaping the gut microbiome over extended periods of evolutionary time.IMPORTANCE The gut microbiome plays a key role in host health. Therefore, it is important to understand the evolution of the gut microbiota and how it impacts, and is impacted by, host evolution. In this study, we explore the relationship between host phylogeny and gut microbiome composition in omnivorous, gregarious cockroaches within the Blattodea order, an ancient lineage that spans 300 million years of evolutionary divergence. We demonstrate a strong relationship between host species identity and gut microbiome composition and found a weaker but significant role for host phylogeny in determining microbiome similarity over extended periods of evolutionary time. This study advances our understanding of the role of host phylogeny in shaping the gut microbiome over different evolutionary distances.
