Abstract Background Insect pests belonging to genus Bactrocera sp. (Diptera: Tephritidae) pose major biotic stress on various fruits and vegetable crops around the world. Zeugodacus and Bactrocera sp. are associated with diverse bacterial communities which play an important role in the fitness of sterile insects. The wild populations of melon fly, Zeugodacus cucurbitae (Coquillett) and Oriental fruit fly, Bactrocera dorsalis (Hendel) were collected from pumpkin and mango fields, respectively. The laboratory populations of Z. cucurbitae and B. dorsalis were mass-reared on bottle gourd and sweet banana, respectively. Bacterial communities present in the gut of wild and mass-reared mature (~ 12 days old) and newly emerged (< 1 h after emergence) male and female adults of Z. cucurbitae and B. dorsalis were assessed. We used Illumina HiSeq next-generation sequencing of 16S rRNA gene to profile the gut bacterial communities of wild and mass-reared mature and newly emerged Z. cucurbitae and B. dorsalis adults. Results We found diverse bacterial composition in the gut of wild and mass-reared Z. cucurbitae (ZC) and B. dorsalis (BD) with varied relative abundance. Few taxonomic groups were common to both the species. The most dominant phyla in all samples of Z. cucurbitae and B. dorsalis adults were Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. The phylum Proteobacteria occurred more in wild Z. cucurbitae (~ 87.72%) and B. dorsalis (~ 83.87%) as compared to mass-reared Z. cucurbitae (64.15%) and B. dorsalis (~ 80.96%). Higher relative abundance of Phylum Firmicutes was observed in mass-reared fruit fly than wild adults. Cyanobacteria/Chloroplast and Actinobacteria were also present with very low relative abundance in both wild as well as mass-reared melon fly and Oriental fruit fly. Enterobacteriaceae (61.21%) was dominant family in the gut of both wild and mass-reared adults. Providencia and Lactococcus were dominant genera with varied relative abundance in wild as well as in mass-reared mature and newly emerged fruit fly adults of both species. Some of the genera like Morganella and Serratia were only detected in mass-reared mature and newly emerged Z. cucurbitae and B. dorsalis adults. Principal Coordinate Analysis (PCoA) showed that fruit fly adult samples were grouped based on species and age of the adults while no grouping was observed on the basis of sex of the adult fruit fly. Conclusions The gut bacterial communities associated with wild and mass-reared mature and newly emerged adults of Z. cucurbitae and B. dorsalis showed variation that depends on species and age of the insects. Understanding the gut microbiota of wild and mass-reared Z. cucurbitae and B. dorsalis using high throughput technology will help to illustrate microbial diversity and this information could be used to develop efficient mass-rearing protocols for successful implementation of sterile insect technique (SIT).

The objective of this study was to develop oral and topical toxicity data for fipronil in Solulys protein bait to wild melon fly, Bactrocera cucurbitae (Coquillett), and the oriental fruit fly, Bactrocera dorsalis (Hendel). For the oral study, both females and males were evaluated, whereas in the contact study only females were evaluated. The 24 h oral LC50 estimates for female B. cucurbitae and B. dorsalis were 113 and 108 mg ai/l, respectively. Female B. cucurbitae were more susceptible than males, but female and male B. dorsalis were equally susceptible to fipronil after the oral route of exposure. Female B. cucurbitae were significantly less susceptible to the fipronil-bait mixture after topical exposure compared with feeding exposure. However, female B. dorsalis were equally susceptible to either route of exposure. At the LC50, B. dorsalis was significantly more susceptible than B. cucurbitae by the topical route of exposure. At the LC90, B. dorsalis was significantly more susceptible than B. cucurbitae by both oral and topical routes of exposure. Results of this study indicate that there are differences In susceptibility between B. cucurbitae and B. dorsalis to fipronil, especially at the LC90. Bactrocera dorsalis was more susceptible to fipronil than B. cucurbitae by oral and topical routes of exposure. LC90 estimates were significantly lower than the 5,333 mg ai/l applied to Amulet Attract and Kill Stations for control of B. cucurbitae and B. dorsalis.
