In females, the ovipositor is very slender and sharply pointed (e), Figure 15: Adults of the Oriental fruit fly. Khamis, F.M., D.K. C.A.B International in association with ACIAR, Wallingford, Oxon. Their Identification and Bionomics. In tropical environments, Oriental fruit flies breed throughout the year. Copeland, I.M. For more information with regards to the many names of this species, head over to the. The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is a destructive agricultural pest causing severe economic losses to more than 600 kinds of fruits and vegetables, such as citrus and chili peppers, and has been listed as a quarantine pest in many countries and regions (Chen et al., 2019). Steiner, L. F., 1957. Although ripe fruit are preferred for oviposition, oviposition on immature fruits has also been observed. EENY-083 Oriental Fruit Fly, Bactrocera dorsalis (Hendel) (Insecta: Diptera: Tephritidae) 1 H. V. Weems, J. In Nilaparvata lugens, miR-2703 targets chitin synthase A to affect the development of nymphs by reducing their chitin content and injection or feeding of miR-2703 mimic causes a lethal phenotype (Chen et al., 2020). Photo credits: Florida Division of Plant Industry, The Tephritidae family comprises non-fruit feeding tephritids, which are rarely pestiferous, , and frugivorous tephritids, which contain several genera which are of major economic concern globally, . Results: The results show that intestinal probiotics elicit beneficial foraging decision and enhance the female reproduction fitness and survival of B. dorsalis (symbiotic and axenic), yet preferences for probiotic diets were significantly higher in axenic flies to which they responded faster compared to full diet. The Oriental fruit fly belongs to the Bactrocera dorsalis species complex, a group of almost 100 morphologically similar tephritid taxa4 Cell basal radial with microtrichae at the base. Some notorious fruigivorous tephritid species include: the Mediterranean fruit fly or Medfly (, . Hoested on. Terga markings: terga III–V withmedial longitudinal black band, tergum III with a basal narrow transverse black band, terga IV and V with black triangular lateral markings, sometimes longitudinal black bands on lateral margins and sometimes without any mark. These markings may form a T-shaped pattern, but the pattern varies considerably. The first signs of an infestation are small discoloured patches on the skin fruit skin, which develop from the "sting" of the female fly during ovipositon. These species have been recognised as possibly the world’s most important pests of horticulture. Image credits: Adapted from various sources; Permission pending 16 Several "outgroup species" were also used in this study, some being species within the, species complex (namely the Australian species, ) and some not being within the species complex (namely, ). In 1985, all Japanese territories were declared free of the Oriental fruit fly after an 18-year program of eradication combining insecticide-impregnated fiberblocks or cotton containing the powerful male attractant methyl-eugenol, and the sterile insect (sterile male) technique. Identification of Pest Species in Oriental Fruit Fly. through the import of infected fruits from native regions in Asia. In addition, the temporal expression patterns of several stage-specific miRNAs in pupa were analyzed. Image credit: Biodiversity Heritage Library 37. Affected young fruit tend to become distorted, callused and usually drop prematurely whereas affected mature fruits develop a water soaked appearance. Figure 6: Life Cycle of Tephritid fruit fly. Foretibia pale fuscous to dark fuscous, mid-tibia pale fuscous to fuscous, hind tibia fuscous to dark fuscous. When mature, larvae emerge from the fruit and jump or drop onto the ground (watch the video below to see how the larvae jumps!). Fresh agricultural produce being transported into each country is meticulously monitored and quarantined in order to isolate and eliminate the accidental introduction of these flies. Whenever the phrase "fruit fly" is mentioned, the image of the model organism, Drosophila melanogaster, comes to mind. Recent advancement in the technologies for studying the gene expression has accelerated the discovery of new players in the insect-baculovirus interactions. Usually approximately 60-80% the length of the larva 35 Whereas tip hardening is key to their ability to penetrate surfaces, it is often also important for probes to be maneuverable through substrates. Fortunately, populations of the Oriental fruit fly are manageable and can be eradicated, albeit a huge financial cost incurred. species, such as Bactrocera zonata, Ceratitis quilicii and Ceratitis capitata. Results of clade monophyly statistics are shown as boxes (1–5 = a priori group analysis; a–g = root‐to tip analysis), with only those achieving 4/5 (orange) or 5/5 (red) shown. Among these noncoding RNAs, miRNAs are the best characterized. The combined phylogenetic tree was produced through partitioned Maximum Likelihood (ML) analysis of data calculated in RAxML. 12 These enveloped viruses have multiple applications in biotechnology and biological pest control methods. For example, miR-8-3p was found to regulate reproduction by controlling mitoferrin to ensure normal spermatogenesis (Tariq et al., 2016b), let-7 targets the ecdysone signaling pathway E75 gene to control larval-pupal development (Peng et al., 2019) and miR-1-3p targets the transformer gene to regulate sex determination (Peng et al., 2020). Figure 7: Table showing some of the common host plants of B. dorsalis. URL: Fabricius located in the Natural History Museum of Denmark,” by Verner Michelsen, Oct 2014. Finally, the function of miR-100/miR-317 and miR-100/miR-285 was explored in larva and pupa, respectively. For a better understanding of baculoviruses, it is necessary to elucidate the molecular basis of insect-baculovirus interactions. In this study, we measured the profile of small RNAs over the developmental transitions of the oriental fruit fly Bactrocera dorsalis from egg hatching, molting, and pupation to adult eclosion. 1.Introduction. The combined phylogenetic tree was produced through partitioned Maximum Likelihood (ML) analysis of data calculated in RAxML. Whenever the phrase "fruit fly" is mentioned, the image of the model organism. Throughout her lifetime (typically 1-3 months), a female fly is able to typically lay between 1,200 to 1,500 eggs (under field conditions) and over 3,000 eggs (under optimum conditions), Figure 4: Gif showing adult Oriental fruit flies on an orchid. Bactrocera dorsalis was first described by Friedrich Hendel as Dacus dorsalis in the "Entomologischen Mitteilungen" or "Entomological Messages" in 1912. The adult, which is noticeably larger than a house fly, has a body length of about 7.0-8.0 mm; the wing is about 7.3 mm in length. Figure 2: Comparison table showing differences between the Common fruit fly and Oriental fruit fly. x; UniProtKB. The long history of host and virus co-evolution suggests that the virus keeps on evolving its arsenals to succeed in infection whereas the host continues investing in antiviral defense mechanisms.

Malaysian fruits, for example, cannot be freely exported to lucrative markets like USA, Japan and Australia, because of strict quarantine regulations in these countries, which prohibit entry of fresh fruits from the fruit flies infested countries unless proper disinfestation treatments are carried out 26 Video credits: YouTube, In the soil, they form tan to dark brown puparium. In this paper, we studied the CPs in the oriental fruit fly (Bactrocera dorsalis), one of the most economically important pests in the Tephritidae family around the world. Docking analysis of a long peptide with several DpCALs modeled with digestive Tenebrio molitor CAL (TmCAL3) as template showed that on adapting to luminal digestion DpCALs (chiefly DpCAL5) changed in relation to their ancestral lysosomal enzyme (DpCAL10) mainly at its S2 subsite. In Aedes aegypti, miRNA-277 plays a critical role in mosquito lipid metabolism and reproduction by targeting insulin-like peptides 7 and 8 (Esslinger et al., 2013; Ling et al., 2017). The first complete mitochondrial genome of. We use cookies to help provide and enhance our service and tailor content and ads. 4, p. 609. One major cause was the large variability in colouration and patterning, between the otherwise morphologically and genetically similar pest species within the, species complex.This resulted in the hindrance of the development of reliable diagnostic characters to distinguish between intra- and inter-specific variation. (Diptera: Tephritidae) using next-generation sequencing and mitochondrial genome phylogeny of Dacini tribe. Once hatched, fruit fly larvae able to tunnel deeply into the fruit flesh for feeding, spreading widely within infested fruit and making the whole fruit unpalatable. Episodic radiations in the fly tree of life. Lateral vittae of scutum present, parallel-sided, yellow, ending at or just behind intra-alar seta. Males attracted to methyl eugenol 36 Version 2.1, A Product of the USDA Compendium of Fruit Fly Host Information (CoFFHI), a Farm Bill Project, “Alerta Verde: La Mosca Oriental de la Fruta,” by DaniSilva TV. Image credit: Bhagat et al. For clarity only supports for backbone nodes are shown; in cases where actual nodal support is absent, posterior probability support values are >0.5 except for those marked with an asterisk (>0.95). In addition, we identified the miRNAs differentially expressed over the developmental transitions. Figure 15: Adults of the Oriental fruit fly. . (permission pending), “Jumping Tephritidae fruit fly maggots,” by, Daniel, C. & J.Grunder, 2012. (Diptera: Tephritidae), a new invasive fruit fly pest for the Afrotropical Region: host plant range and distribution in West and Central Africa. Watch the video below to see the impacts of Oriental fruit fly infestations on the community in Mpumalanga, South Africa. MicroRNAs (miRNAs) are endogenous small noncoding RNAs (18–25 nt) that are involved in many physiological processes including development, cancer, immunity, apoptosis and host-microbe interactions through post-transcriptional regulation of gene expression. Scutum colour (other than vittae) red-brown to black. Singh, R.B., 1991. This study provides a useful resource for studying the regulatory role of miRNAs in the developmental transitions of B. dorsalis, and the involvement of miR-100\miR-317 and miR-100/miR-285 in the process of pupation and adult eclosion, respectively. The Oriental fruit fly, = em>Bactrocera dorsalis (Hendel= , 1912), is a member of the Tephritidae (fruit flies) family. Image obtained from Biodiversity Heritage Library (BHL). 5 A similar conclusion arrived from structure alignment-based clustering of DpCALs based on structural similarity of the modeled structures. Youtube, 21 Sep 2015. . 1.Intr= oduction. This document is EENY-083 (originally published as DPI Entomology Circulars No. Squares at the nodes are Bayesian posterior probabilities for 1, 2, 5 and 6, ML bootstrap values for 3, 4, 7 and 8. [13-16]. MicroRNAs (miRNAs) constitute a novel class of gene expression regulators and are found to be involved in regulating a wide range of biological processes such as development, cell cycle, metabolism, apoptosis, immunity, host-pathogen interactions etc. . Notorious pest species known for causing immense economic lossesAdult's appearance: Variable colour & pattern; prominant yellow and dark brown to black markings on dorsal surface of thorax; Generally with two horizontal black stripes and a longitudinal mark on dorsal surface of abdomen, Information: Animal Diversity Web7 okinawanus Shiraki, 1933 Chaetodacus okinawanus Shiraki, 1933 Dacus dorsalis Hendel, 1912 Musca ferruginea Fabricius, 1794 Homonyms Bactrocera dorsalis (Hendel, 1912) Common names oriental fruit fly in English 東方果實蠅 in language. Figure 1: Oriental fruit flies on a fruit. Mahanarva fimbriolata does not seem to have digestive CALs and their digestive CABs are mainly expressed in the first digestive section of the midgut and do not diverge much from their lysosomal counterparts.

Figure 16: Larvae of the Oriental fruit fly. . The oriental fruit fly, Bactrocera dorsalis (Hendel), is a very destructive pest of fruit in areas where it occurs. Steiner traps baited with a lure and toxicant are also used to monitor the presence and control of the flies. Analysis of miRNA expression profiles facilitated the identification of differentially expressed miRNAs (DEMs), of which predicted target genes were analyzed, and RT-qPCR was performed to confirm sequencing results. The conversion of the glycerophospholipid phosphatidic acid (PA) into diacylglycerol (DAG) is essential for the biosynthesis of membrane phospholipids and storage fats. 11- 29. spinulosa Megachile centuncularis Megachile circumcincta Megachile dorsalis Megachile lapponica Megachile ligniseca Megachile maritima Megachile versicolor 1932 Megachile centuncularis Linnaeus, 1758 Megachile cinnamomea Alfken, 1926 Megachile concinna Smith, 1879 Megachile dorsalis Perez, 1879 Megachile esseniensis This list of Megachile species is an almost comprehensive listing of … One major cause was the large variability in colouration and patterning, between the otherwise morphologically and genetically similar pest species within the Bactrocera dorsalis species complex.This resulted in the hindrance of the development of reliable diagnostic characters to distinguish between intra- and inter-specific variation. Lectotype ♀ in The Natural History Museum, London, U.K. Shiraki, 1933; Hardy & Adachi, 1956; Hardy, 1969, Hardy & Adachi, 1956; Hardy, 1969; 1973; 1974, Drew & Hancock, 1994; Norrbom et al., 1998; Mahmood & Hasan, 2005; White, 2006; Drew et al., 2007, Lectotype designation by Drew & Hancock, 1994, Holotype in HEIQ; synonymized by Drew & Romig, 2013: 76. 22). The fruit fly genus Bactrocera within the family Tephritidae consists of over 460 described species, mostly distributed in the Asia-Pacific region. (accessed on 14 Nov 2016). Eggs are laid in batches of 1-20 eggs per fruit, just under the fruit's skin, where fruit-decaying bacteria is subsequently deposited. Results of clade monophyly statistics are shown as boxes (1–5 = a priori group analysis; a–g = root‐to tip analysis), with only those achieving 4/5 (orange) or 5/5 (red) shown. Image adapted from Okinawa Prefectural Fruit Fly Eradication Project Office, Barrel-shaped with most larval features unrecognisable. This situation is also faced in the Philippines, Thailand, Indonesia, India, Taiwan and China. Many other regions in the world are at risk of invasion and establishment of B. dorsalis [2,3]. Molecular and morphological data from 149 of 157 dipteran families, including 30 kb from 14 nuclear loci and complete mitochondrial genomes as well as 371 morphological characters were used in this analysis45 What led to this decision was in particular, the scutum colour of the Kenyan specimens which ranged "from pale red-brown to black with the existence of variable lanceolate-patterned intermediates". Generally, the abdomen has two horizontal black stripes (b) and a longitudinal median stripe extending from the base of the third segment to the apex of the abdomen (c). . Image: Malcolm Storey © Copyright, Information: Plant Health Australia8 With the rapid development of high-throughput small RNA sequencing technologies, miRNAs can be efficiently and comprehensively identified, in both model and non-model species. The genus Bactrocera, on the other hand is not monophyletic. Bactrocera zonata (Diptera: Tephritidae) originates in South and South-East Asia where it attacks many fruit species (more than 50 host plants), including guavas, mangoes, peach, apricots, figs and citrus.
