Adult female oriental fruit fly, Bactrocera dorsalis (Hendel), laying eggs in fruit. Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. Dacus (Strumeta) correctus (Bezzi)
Caudal view of an adult female guava fruit fly, Bactrocera correcta (Bezzi), showing ovipositor sheath and fully extended ovipositor. Larvae of many species of fruit flies are unknown. Anderson PJ, Dixon WN. It has spread to other parts of the world, in particular to several countries in the Near East and to Egypt. 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 ⦠Adults emerge 7 - 10 days later and feed for a period of ti⦠The other principle species recorded were B. dorsalis and B. zonata, although they were not as abundant as B. correcta. To compare relative cold treatment tolerance across the economically important tephritid fruit flies (Diptera: Tephritidae), Bactrocera carambolae Drew & Hancock, Bactrocera correcta (Bezzi), Bactrocera cucurbitae (Coquillett), four populations of Bactrocera dorsalis (Hendel), Bactrocera zonata (Saunders), and Bactrocera ⦠In his original description of Bactrocera correcta (as Chaetodacus correctus, Bezzi (1915)) stated that Bactrocera correcta was very near Dacus zonatus (now Bactrocera zonata (Saunders) - the peach fruitfly), but it is distinguished by the color of the thorax, and chiefly by the facial black spots being united to form a black transverse band; the whitish cross-band on the second abdominal segment is less developed, and the hind tibiae of the male are distinctly tuberculate before the end, similar to that of two closely related species, Bactrocera zonata (previously Dacus zonatus) and Bactrocera tuberculata (Bezzi) (previously Dacus tuberculatus). A hardening temperature of 35°C produced the largest benefit for B. correcta, while 38°C led to the largest hardening response for B. dorsalis . Results. White IM, Elson-Harris MM. B. correcta was recorded for the first time in Tamil Nadu, India, in 1995, where it caused guava fruit damage ranging from 60 to 80%. Guava Fruit Fly (Bactrocera correcta), ... A life cycle is an estimate of insect phenology based on a heat degree day temperature driven model. These eggs get hatched within 1-2 days. Both species are widely distributed in tropical and subtropical countries, especially in Asia. Photograph taken in Australia. 1973.

⦠Bactrocera zonata, in India called "the Ranchi peach-pest," is very injurious to peach, mango, and several other fruits, including ripe Aegle marmelos (L.) Correa (Bael fruit), Careya arborea Roxb., Ficus carica L. (cultivated fig, common fig, lemon fig), Lagenaria vulgaris (white gourd), and Manilkara zapota (L.) Van Royen (as Achras sapota) (sapodilla), all of which must be considered potential hosts of Bactrocera correcta. Bactrocera correcta (Bezzi), often referred to as the "guava fruit fly" (although the larvae of many other species of fruit flies feed on guava - and Anastrepha striata Schiner is also called the "guava fruit fly") (White and Elson-Harris 1994), was detected for the first time in the Western Hemisphere when one female was found on 6 August 1986 in Garden Grove, Orange County, California. ⦠It was first recorded in China in 1982 in Yuanjiang, in southern Yunnan Province. endstream

The results show that with B. dorsalis (Liu et al. Egg: Eggs are laid in fruit by female. Adults usually are collected by use of stickyboard and baited traps. Citation: Zhao Y, Li Z, Gu X, Su Y and Liu L (2020) Imaginal Disc Growth Factor 6 (Idgf6) Is Involved in Larval and Adult Wing Development in Bactrocera correcta (Bezzi) (Diptera: Tephritidae). Photograph by Division of Plant Industry. Microreticulation near base of the ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). 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. life cycle 1 fly F2 2 flies within a 3 mile (4.8 km) radius during 1 If ALL finds are >4.5 miles (7.2 km) from commercial host production area: 8 flies (either sex) within a 3- mile (4.8 km) radius during 1 life cycle. sexes entirely yellow. Piercer gradually tapered to a short point, about 1.0 mm in length. 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. No stages develop at 15°C or less, the optimum temperature is 25-30°C (Qureshi et al., 1993). Thoracic-Lateral view of an adult guava fruit fly, Bactrocera correcta (Bezzi). The Insect Pest Control Subprogramme carries out Research and Development activities (R&D) at the Insect Pest Control Laboratory located at the FAO/IAEA Agriculture and Biotechnology Laboratories in Seibersdorf, 35 km southeast of Vienna. B. correcta (Guava FF), etc. The mature larva emerges from the fruit, drops to the ground, and forms a tan to dark brown puparium. (2008). An effort should be made to rear some larvae to adults in order to correctly associate larvae and adults and provide the basis for accurate specific identification. Photograph by Pest and Diseases Image Library, Bugwood.org. Bactrocera correcta occurs in India, Pakistan, Nepal, Sri Lanka, and Thailand. If an infestation were to go unchecked and to become established in U.S. areas such as California or Florida, Bactrocera correcta has the potential to become a major pest of citrus, peach and several kinds of tropical and subtropical fruit hosts.

Photograph by Pest and Diseases Image Library, Bugwood.org. Ovipositor tip of an adult female guava fruit fly, Bactrocera correcta (Bezzi). The adult lifespan for B. dorsalis is about 90 days, and the flies have been reported to travel up to 30 miles in search of new egg laying sites and food, such as decaying fruit and plant nectar. %PDF-1.6

Bactrocera correcta has been detected numerous times in California since 1986 and in Florida since 1999 (Anderson and Dixon 2008), but has not become established. The results the femalesâ mean longevity of D. ciliatus may also help to understand the life cycle was 42.0 days at 25 C. strategy of B. zonata and D. ciliatus in its Temperature is ⦠Generally, life cycle of fruit fly indicated six development stages: mating, oviposition, egg, larvae, pupae and adults while the larval have three development stages (1st, 2ndand 3rdinstar). In his redescription of Bactrocera correcta (as Dacus correctus), Hardy (1973) noted the close relationship of this species with Bactrocera zonata and that the wing markings and morphological details are similar in the two. Figure 10. California Department of Food and Agriculture Pest Detection/Emergency Projects personnel responded promptly by deploying Jackson/methyl eugenol and McPhail traps at 50 traps in the epicenter miles. The guava fruit fly, Bactrocera correcta (Bezzi) (Diptera: Tephritidae), is an invasive pest of fruit and vegetable crops that primarily inhabits Southeast Asia and which has the potential to become a major threat within both the Oriental and Australian oceanic regions as well as California and Florida. Bactrocera correcta (Bezzi) has also been known as: Chaetodacus correctus Bezzi,
In India, males were found to be attracted to tulsi plant (Ocimum sanctum) which yields aromatic oils, 40% of which are methyl eugenol. Front. Pacific Insects Monograph 31: 1-353. Oxon, UK. ... LIFE CYCLE. Wings are almost entirely hyaline with the subcostal cell yellow, a very faint tinge of yellow along the costal margin in apex of cell R1, and a narrow brown spot at lower apex of cell R3 and upper apex of cell R5. The duration of various immature stages varies at different temperatures. Larval: Larvae plays a key role in damaging guava fruits as it feeds on fruit pulp for its development. The wings are clear with a light brown band along the leading edge and a spot at the tip. A transcriptional and functional analysis of heat hardening in two invasive fruit fly species, Bactrocera dorsalis and Bactrocera correcta Evol Appl .

This study focuses more on life history of B. carambolaethat are need to be determine before any management control takes place. This marking sometimes is interrupted in the median portion, but in fully hardened specimens it appears to be complete at least as a narrow brown to black line. After introduction, it can easily disperse as it has a high reproductive potential, high biotic potential (short life cycle, up to 10 generations of offspring per year depending on temperature), a rapid dispersal ability and a broad host range. Genet. The adults laid their eggs in the fruit causing blemishes and discoloration and the larvae bored inside the fruit.
