bactrocera dorsalis life cycle

Life tables were established for trichlorphon-resistant and susceptible Bactrocera dorsalis strains based on the laboratory observations. Five male Bactrocera dorsalis specimens were detected in five separate Methyl Eugenol baited traps in urban areas in the coastal town, Jeffreys Bay between 28 February and 21 May 2019. The Oriental fruit fly, Bactrocera dorsalis (Hendel, 1912), is a member of the Tephritidae (fruit flies) family. The common species reported on mango include the Queensland fruit fly (B. tryoni Frogatt), Oriental fruit fly (B. dorsalis Hendel), B. zonata (Saunders), B. neobumeralis (Hardy), B. jarvisi (Tryon), and B. frauenfeldi (Schiner) (Yahia et al., 2006a). Bactrocera dorsalis females produced significantly more eggs when fed on guava (623.30 eggs female-1) than on papaya (527.80 eggs female-1) or banana (399.60 eggs female-1). Therefore, the further study recommended that mango was the most acceptable fruit for faster development of Bactrocera dorsalis. Three larval stages develop inside the fruit, feeding on the plant tissue. Approximately one life cycle period has passed without further detections. common name: a guava fruit fly scientific name: Bactrocera correcta (Bezzi) (Insecta: Diptera: Tephritidae) Introduction - Synonymy - Distribution - Identification - Hosts - Survey and Detection - Selected References Introduction (Back to Top). For life-cycle study, slices of ripe guava var. The first-instarlarvae ofthe fruit-flieswere then exposed to 100 females of Biosteres persulca­ Trichlorphon-resistant B. All applications and simulations were made using the Insect Life Cycle Modeling (ILCYM) software. 12 The mitochondrial DNA (mtDNA) sequences were obtained from the 4 species of Bactrocera by PCR and sequenced. Three larval stages develop inside the fruit, feeding on the plant tissue. The life cycle from eggs to male (146.95 ± 3.43 d) and female (164.94 ± 3.85 d) adults was significantly longer on papaya than those on banana and guava. In past years, this species has invaded South America via the trade of fruits from Indonesia. The mitochondrial DNA (mtDNA) sequences were obtained from the 4 species of Bactrocera by PCR and sequenced. are pests of major importance in the eastern hemisphere. Life Cycle Eggs of B. dorsalis are white to yellow-white and are laid below the skin of the host fruit. S1 in the supplemental material), indicating that the bacterial libraries produced from our samples well represented the microbial communities present in B. dorsalis. It is one of the major pest species in the genus Bactrocera with a broad host range of cultivated and wild fruits, second in damage only to Bactrocera … This species was discovered by Drew and Hancock in 1994. Laboratory study was undertaken at Shendi area, River Nile State, Sudan during season 2007-2008 to determine the Life cycle and sex ratio of three species of fruit flies including Bactrocera invadens, Ceratitis capitata and Ceratitis cosyra. MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs that regulate various biological processes including sexual dimorphism. Datasheet of Bactrocera occipitalis (BCTROC) Little is known about the biology of B. occipitalis.The general life cycle is considered similar to those of other Bactrocera species infesting fruits: eggs are deposited inside fruits by the female puncturing the fruit skin. 1978). Bactrocera dorsalis completed its development at temperatures ranging between 15 and 33 ᵒC with the mean developmental time of egg, larva, and pupa raging between 1.46 – 4.31 days, 7.14 – 25.67 days, and 7.18 – 31.50 respectively. 12 2.6 Sampling of Fruit Flies. The wings are clear. Here, we present empirical evidence that commensal bacteria mediate mate-selection in the Oriental fruit fly, Bactrocera dorsalis. The adult oriental fruit fly is somewhat larger than a housefly, about 8 mm in length. 11 2.5.1 Ovipositor of Female Bactrocera carambolae. 12 2.7 Hatchability Percentage. Bactrocera carambolae are specifically native to Malaysia, southern Thailand and western Indonesia. Fruit flies have a great influence on fruit and vegetable industry of Pakistan. Most species that have been investigated demonstrate that the life cycle can be accomplished more quickly during warmer temperatures than in even slightly less warm temperatures. Commensal bacteria influence many aspects of an organism’s behaviour. The female has a pointed slender ovipositor to deposit eggs under the skin of host fruit. Primers for the amplified of the complete mitochondrial of Bactrocera dorsalis, Bactrocera papayae, Bactrocera carambolae, Bactrocera philippinensis, were designed based on the complete mitochondrial genome of Bactocera oleae and Ceratitis capitata in GenBank. Bactrocera dorsalis is one of the most economically important fruit flies around the world. Drew, RA and Hancock, DL (1994) The Bactrocera dorsalis complex of fruit flies (Diptera: Tephritidae: Dacinae) in Asia. Bactrocera dorsalis Delimitation Survey Timeline. Bactrocera spp. 1.Introduction. complex (Bactrocera dorsalis and relatives) and the melon fly (Bactrocera cucurbitae). The oriental fruit fly, Bactrocera dorsalis (Hendel), is a destructive agricultural pest that is widely distributed in many areas of the Asian countries [].It causes severe economic loss and trade restrictions to vegetables and fruits by ovipositing inside more than 450 host plant species (USDA, 2016). Although its' name does not illicit much response here in Singapore, in countries such as the United States and Kenya, the mention of the Oriental fruit fly will send agricultural farmers, fruit vendors, immigration authorities fuming mad. Life history and adult dynamics of Bactrocera dorsalis in the citrus orchard of Nanchang, a subtropical area from China: implications for a control timeline Xiaozhen Lia,, Haiyan Yangb, Tao Wanga, Jianguo Wang a, Hongyi Wei a College of Agronomy, Jiangxi Agricultural University, Nanchang 330045 China Bactrocera dorsalis females produced significantly more eggs when fed on guava (623.30 eggs female −1) than on papaya (527.80 eggs female −1) or banana (399.60 eggs female −1). 10 2.5 The Characteristics and Life Cycle of Bactrocera. As the maggots are confined within the fruit in which they hatch, However, studies on the influence of commensal bacteria in insect mate-selection are scarce.
