The Microbiome of Field-Caught and Laboratory-Adapted Australian Tephritid Fruit Fly Species with Different Host Plant Use and Specialisation

摘要: Tephritid fruit fly species display a diversity of host plant specialisation on scale from monophagy to polyphagy. Furthermore, while some prefer ripening fruit, few are restricted damaged or rotting fruit. Such use may be reflected in the microbial symbiont tephritids and their grade dependency microbiomes. Here, we investigated microbiome six tephritid three genera, including that polyphagous pests (Bactrocera tryoni, Bactrocera neohumeralis, jarvisi, Ceratitis capitata) monophagous specialist cacuminata). These were compared with non-pestiferous but is (Dirioxa pornia). The bacterial community associated whole flies was analysed by 16S ribosomal DNA (rDNA) amplicon pyrosequencing detect potential drivers taxonomic composition. Overall, dominant families Enterobacteriaceae Acetobacteraceae (both Proteobacteria), Streptococcaceae Enterococcaceae Firmicutes). Comparisons across genera found different composition limited consistent differentiation between species. Within species, seemed influenced environment, possibly diets; beyond this, identity ecology also had an effect. D. pornia most distinct other five which due its ecologically niche as opposed favoured Our study first compare microbiomes thus delivers important information about turnover within application pest management strategies.
