Microbiota and potential opportunistic pathogens associated with male and female fruit flies of Malaysian Bactrocera carambolae (Insecta: Tephritidae)
Bactrocera carambolae Drew & Hancock is an agricultural pest that causes considerable damage to various fruit crops in Southeast Asia and South America. We report here the bacterial communities associated with field-caught male and female adult flies from University Malaya campus. The microbiota...

Bactrocera carambolae Drew & Hancock is an agricultural pest that causes considerable damage to various fruit crops in Southeast Asia and South America. We report here the bacterial communities associated with field-caught male and female adult flies from University Malaya campus. The microbiota was determined by targeted 16S rRNA gene (V3–V4 region) sequencing using the Illumina MiSeq. At 97% similarity, four bacterial phyla (with relative abundance of ≥1% in at least one specimen) – Bacteroidetes, Firmicutes, Proteobacteria, and Tenericutes – were recovered from the adult flies. Proteobacteria was the predominant phylum in all the samples, with the female flies (86.81 ± 6.57%) having higher mean relative abundance than the male flies (71.57 ± 18.37%). The Firmicutes was more abundant in the male flies (14.47 ± 17.30%) than female flies (0.69 ± 1.25%). There were in total seven classes, nine orders, 13 families, 23 genera, and 31 putative species.
