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. %%EOF The developmental time of the egg, larva … 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). Kapoor VC, Hardy DE, Agarwal ML, Grewal JS. Hardy (1973) stated that Bactrocera correcta is differentiated from other species known from Thailand and surrounding regions by having the face with the black transverse band at the lower third and by having the costal end of the wing interrupted in cell R3, beyond the tip of vein R2+3. Anterior view of an adult guava fruit fly, Bactrocera correcta (Bezzi). The results show that with B. dorsalis (Liu et al. endstream endobj 246 0 obj <. Legs mostly yellow.

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. A genetic sexing strain (GSS) is an essential component for pest control using the sterile insect technique (SIT).

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 i… 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. Egg: Eggs are laid in fruit by female. The larvae then drop from the fruit to pupate in the soil. Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. Bactrocera correcta occurs in India, Pakistan, Nepal, Sri Lanka, and Thailand. White IM, Elson-Harris MM. Trap density in the area of the original finds was five traps per square mile. Bactrocera dorsalis and B. correcta are serious pests of agricultural fruit crops. Life History Development from egg to adult under summer conditions requires about 16 days. (ber, jujube, Chinese date). Bactrocera dorsalis and B. correcta were sourced from their first in‐ vaded range in China, from Guangdong province (N 23.40, E 113.22) for B. dorsalis with the annual mean temperature 21.7°C and from Yunnan province (N 23.60, E 102) for B. correcta with the annual mean temperature 25.8°C (Li, Wu, Chen, Wu, & Li, 2012; Liu & Ye, … Bezzi (1915) noted that Bactrocera correcta lives in company with Bactrocera zonata (WW Saunders, 1841) and Bactrocera tuberculata (Bezzi, 1915), feeding on the same fruits.

Description Bactrocera correcta (Bezzi, 1916), commonly known as the guava fruit fly, is of concern as an invasive pest in tropical and subtropical countries. Guava Fruit Fly (Bactrocera correcta), ... A life cycle is an estimate of insect phenology based on a heat degree day temperature driven model. Immature stages of Bactrocera correcta have not been described in the literature, and specimens were unavailable to the senior author from which to prepare descriptions. Bactrocera correcta is similar to the exotic B. dorsalis but differs in having transverse facial spots, an apical wing spot instead of a costal band and costal cells devoid of microtrichia. Hardy DE. 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.

Recorded hosts include Citrus spp., Coffea canephora Pierre ex Froehn. Pupal duration is … 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. Adults emerge 7 - 10 days later and feed for a period of ti… Sterna of both 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. The adults laid their eggs in the fruit causing blemishes and discoloration and the larvae bored inside the fruit. We monitored the spread of B. correcta in the field during 2017 and 2018, and found that it had … The guava fruit fly, Bactrocera correcta, is one of the major pests affecting mango (Mangifera indica) and guava (Psidium guajava) production in China.

Photograph by Pest and Diseases Image Library, Bugwood.org. 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. Cubital cell faintly yellow and no cubital streak developed. 44-134. Bactrocera correcta is a brightly-colored brown and yellow fly approximately 6.0 millimeters (mm) in length. Of the two additional adult males detected, one was trapped in a Jackson/methyl eugenol trap hung in a peach tree in Westminster, the other in a Jackson/methyl eugenol trap deployed in a grapefruit tree in Midway City. 1980.

Ovipositor tip of an adult female guava fruit fly, Bactrocera correcta (Bezzi). 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%. These eggs get hatched within 1-2 days. 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. However, George Steyskal, in his letter dated 26 August 1986, observed that specimens in the (U.S.) National Museum of Natural History collection, all identified by Hardy, show distinct interruption of the two facial bars. Individual flies at different developmental stages, from 6-h-old eggs to third instars, were exposed to 0.92 mg/liter phosphine for 1–7 d at 5°C. Ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). Single adults were captured in fruit fly detection trap in Apopka (Orange County) on 4 May 2001, in Oviedo, FL, on 30 July 2001, in Orlando (Orange County) on 29 February 2008 (Anderson and Dixon 2008), and in Orange County in late August 2011.

There is no developmental information on B. correcta, but it is probably similar to B. zonata and B. … 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. Thoracic-Lateral view of an adult guava fruit fly, Bactrocera correcta (Bezzi). Bactrocera correcta (Bezzi) Asian guava fruit fly is less well known than other economic fruit flies, because, in its native areas it usually occurs in mixed assemblages of more aggressive competitors, such as oriental fruit fly and peach fruit fly. Larvae hatch in a few days and burrow into interior of the fruit to feed on the pulp for 4 - 12 days. Caudal view of an adult female guava fruit fly, Bactrocera correcta (Bezzi), showing ovipositor sheath and fully extended ovipositor.
