Rhodnius prolixus is an obligatorily hematophagous insect known as an important vector of Chagas disease. 1.Introduction. A new invasive fruit fly species from the Bactrocera dorsalis (Hendel) group detected in East Africa. Importantly, both PA and DAG can also serve signaling functions in the cell. First flagellomere shorter than ptilinal fissure, face with a black spot in each antennal furrow. Proceedings First International Symposium on Fruit flies in the Tropics (eds. , and frugivorous tephritids, which contain several genera which are of major economic concern globally3 Photo credit: Scott Bauer (permission pending), Video 1: Video showing jumping tephritid larvae found inside a squash. Here, two essential genes of the autophagic pathway, Atg6/Beclin1 (RpAtg6) and Atg8/LC3 (RpAtg8), were silenced and the storage of lipids during starvation in Rhodnius prolixus was monitored. Comparing miRNA profiles over different developmental stages has facilitated the identification of miRNAs involved in controlling developmental stage transitions (Menzel et al., 2019; Nouzova et al., 2018). . B. dorsalis s.s. (purple), B. papayae (dark blue), B. philippinensis (light blue) and B. carambolae (green)]. 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). Bactrocera dorsalis is native to tropical Asian countries such as Singapore, India, Malaysia and Bangladesh. Applied Entomology and Zoology, Vol. Photo credit: Verner Michelsen, Originally described by Hendel in 1912 as, , the Oriental fruit fly has since been redescribed, reclassified and renamed multiple times by numerous authors internationally. In particular, B. dorsalis belongs to a complex of physically similar flies called the Bactrocera dorsalis complex, whose defining characteristics include a mostly black thorax and dark T-shaped marking on the fly's abdominal segment. Bactrocera Bactrocera dorsalis Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Diptera Family: Tephritidae Subfamily: Dacinae Tribe: Dacini Genus: Bactrocera Macquart, 1835 Type species Bactrocera longicornis Macquart, 1835 Species B. correcta B. dorsalis B. oleae B. tryoni B. zonata Hundreds more Diversity 464 species Synonyms Aglaodacus Munro, 1984 Apodacus Perkins, 1939 Chaetodacus Bezzi, 1913 Dasyneura Saunders, 1842 Hemigymnodacus Hardy, 1973 Mar… These tiny molecules are abundantly found in higher eukaryotes and viruses. The prolonged difficulties in differentiating putative species, coupled with the highly disjunct geographic distribution of closely-related species within the, species complex, has resulted in grouping errors in the form of separate populations of, worldwide being described as new separate Bactroceran species, One example of a grouping error was a group of, specimens detected in Kenya in 2003. Many of these are either known or believed to have the potential to damage a diverse array of important crops. 21 and 303),, one of a series of the Entomology and Nematology Figure 15: Adults of the Oriental fruit fly. 17 Larvae (commonly known as maggots) develop within the fruit10 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. In addition, the temporal expression patterns of several stage-specific miRNAs in pupa were analyzed. 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. This page focuses solely on the Oriental fruit fly. The hopper hAT-family transposable element isolated from the Oriental fruit fly, Bactrocera dorsalis, is distantly related to both the Drosophila hobo element and the Activator element from maize. Gif made using. Image credit: 47. The wings are clear (d). 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. Once mature, the flies emerge from their puparia as adult flies. This study identified critical miRNAs involved in the transitions of this important holometabolic model and pest insect B. dorsalis from egg hatching to adult eclosion, thus providing a useful resource for exploring the regulatory role of miRNAs during insect post-embryonic development. It is a member of the family Tephritidae, which are the most agriculturally important family of flies, and can be considered an out-group to well-studied members of the family Drosophilidae. 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. ... Family Tephritidae ( 1TEPHF ) Genus Bactrocera ( 1BCTRG ) Species Bactrocera dorsalis ( DACUDO ) … Affected young fruit tend to become distorted, callused and usually drop prematurely whereas affected mature fruits develop a water soaked appearance. The availability of a complete genome sequence (NCBI Assembly: ASM78921v2) allowed the identification of 164 CP genes in B. dorsalis. 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. .

Image adapted from Okinawa Prefectural Fruit Fly Eradication Project Office34. Eggs laid in a period of 1 h from adults ten days after eclosion were collected and placed into water on fresh-keeping film to be allowed to develop. Some of these proteins are members of the extracellular immune signaling network found in feeding larvae, and others may play additional roles and hence confer new features in the later life stages. Figure 3: Phylogeny tree indicating positions of the Tephritidae and Drosophilidae families on the Schizophora phylogeny tree. Furthermore, we found that some genes involved in lipid metabolism had their expression levels altered in silenced insects, such as the Brummer lipase (down regulated) and the adipokinetic hormone receptor (up regulated), suggesting that, as previously observed in mammalian models, the autophagy and neutral lipolysis machineries are interconnected at the transcriptional level. Wing length: 5.4–6.9mm. Figure 7: Table showing some of the common host plants of B. dorsalis. Setae: anterior supra-alar present, prescutellar present, scutellar one pair. Romig, 2013. It has spread to other parts of the world, in particular to several countries in the Near East and to Egypt. For this reason, Oriental fruit flies are known to spread far and fast, causing much damage to crop fruits 10 According to ICZN (1999), three species are treated as synonyms under B. dorsalis s.l.
