The wings are clear. Keywords: Biology, cucurbit and Bactrocera cucurbitae This is the typical life cycle of a fruit fly2.

The d uration of total life cycle was 16.81±2.18days during 2015 in June and July under room temperature in meerut condition.

The body color is variable but generally bright yellow with a dark T shaped marking on the abdomen. Eggs are minute cylinders laid in batches. 12 2.6 Sampling of Fruit Flies. The mitochondrial DNA (mtDNA) sequences were obtained from the 4 species of Bactrocera by PCR and sequenced. exposed to approximately 2000 females ofBactrocera (B) sp. 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. Background The oriental fruit fly, Bactrocera dorsalis (Hendel), is one of the most economically important pests in the world, causing serious damage to fruit production. This species was discovered by Drew and Hancock in 1994. total life cycle was finalized in 24.50 to 46.50 days on different hosts however; it was little on mango than rest of the fruits. The adult oriental fruit fly is somewhat larger than a housefly, about 8 mm in length. The Oriental fruit fly, Bactrocera dorsalis (Hendel, 1912), is a member of the Tephritidae (fruit flies) family. 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. Approximately one life cycle period has passed without further detections. 10 2.4 Bactrocera carambolae Distribution. Therefore, traps were serviced daily for one full life cycle after the last B. dorsalis detection and weekly thereafter for a period of two additional life cycles. Bactrocera carambolae, also known as the carambola fruit fly, is a fruit fly species in the family Tephritidae, and is native to Asia. 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). Approximately one life cycle period has passed without further detections. The female has a pointed slender ovipositor to deposit eggs under the skin of host fruit. 11 2.5.1 Ovipositor of Female Bactrocera carambolae. 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. 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. Bulletin of Entomological Research Supplement Series 2 , 1 – 68 . 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. 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). S1 in the supplemental material), indicating that the bacterial libraries produced from our samples well represented the microbial communities present in B. dorsalis. However, lack of genetic information on this organism is an obstacle to understanding the mechanisms behind its development and its ability to resist insecticides. However, studies on the influence of commensal bacteria in insect mate-selection are scarce. Bactrocera spp. As the maggots are confined within the fruit in which they hatch, dorsalis strain had longer pupal and preoviposition periods, and mean generation time compared to the trichlorphon susceptible strain. Fruit flies have a great influence on fruit and vegetable industry of Pakistan. complex (Bactrocera dorsalis and relatives) and the melon fly (Bactrocera cucurbitae). It is a major pest on mango and causes up to 31% fruit loss in India3. AN organism exploits its resources to maximize its fit-ness. Three larval stages develop inside the fruit, feeding on the plant tissue. Keywords: Bactrocera dorsalis, climate change, geo-graphical distribution, Oriental fruit fly. 12 2.7 Hatchability Percentage. Keywords: Bactrocera dorsalis, host biomass, mango, oviposition strategy. 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 Life Cycle Eggs of B. dorsalis are white to yellow-white and are laid below the skin of the host fruit. MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs that regulate various biological processes including sexual dimorphism. 1978). The damage caused by the above mentioned species was determined on fruits of mango, guava and citrus. For life-cycle study, slices of ripe guava var. Therefore, the further study recommended that mango was the most acceptable fruit for faster development of Bactrocera dorsalis. Trichlorphon-resistant B. 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. 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. 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. 10 2.5 The Characteristics and Life Cycle of Bactrocera. Here, we present empirical evidence that commensal bacteria mediate mate-selection in the Oriental fruit fly, Bactrocera dorsalis. Section 2 covers the life cycle of typical fruit flies, male lures (particularly methyl eugenol and Cuelure), protein baits, fruit fly damage and crop losses, and the host fruit preferences of … 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 … Three larval stages develop inside the fruit, feeding on the plant tissue. The mitochondrial DNA (mtDNA) sequences were obtained from the 4 species of Bactrocera by PCR and sequenced. 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. Life tables were established for trichlorphon-resistant and susceptible Bactrocera dorsalis strains based on the laboratory observations. Bactrocera dorsalis Delimitation Survey Timeline. Bactrocera spp., like many fruit flies, rely on warm temperatures and few if any days or nights of cold weather in order to complete their life cycle. THE Oriental fruit fly (OFF), Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is a destructive polyphagous pest on a range of wild and cultivated fruit crops1,2. All applications and simulations were made using the Insect Life Cycle Modeling (ILCYM) software. B. dorsalis will not develop at temperatures below 55 degrees Fahrenheit. Bactrocera dorsalis is a species of tephritid fruit fly that is endemic to Southeast Asia, but has also been introduced to Hawai'i, the Mariana Islands and Tahiti. This section gives an overview on the two main climatic factors impacting the development of the olive fruit fly in Mediterranean regions: temperature and … Keywords: Oviposition, pupal period, hosts, Bactrocera dorsalis Introduction 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. 1.Introduction. 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).
