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. Genet. Pacific Insects Monograph 31: 1-353. Figure 4. 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. Both species are widely distributed in tropical and subtropical countries, especially in Asia. 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.
This laboratory-based study examined the effects of low-temperature phosphine fumigation on the survival of the eggs and larvae of the guava fruit fly, Bactrocera correcta (Bezzi). Bactrocera correcta Interior Quarantine. Figure 3. (a) Pest. Bactrocera dorsalis performed better than B. correcta in the 37â40°C hardening range, while B. correcta differed from B. dorsalis in the 34â36°C range. Trap density in the area of the original finds was five traps per square mile. Wing of an adult guava fruit fly, Bactrocera correcta (Bezzi).

The wings are clear with a light brown band along the leading edge and a spot at the tip. The following is a generalized life history for Bactrocera fruit flies. 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. Steck GJ. Figure 5. Bactrocera correcta is a brightly colored little fly, predominately black with lateral yellow stripes, approximately 5.4 mm in length. 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.

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.

Thoracic-Lateral view of an adult guava fruit fly, Bactrocera correcta (Bezzi). The adults laid their eggs in the fruit causing blemishes and discoloration and the larvae bored inside the fruit. The effect of temperature on the development and survival of the guava fruit fly,Bactrocera correcta (Bezzi) (Diptera: Tephritidae) from egg to adultâs pre-ovipositional stage was studied in laboratory under 5 different constant temperatures: 18, 24, 30, 33 and 36°C.

Larval: Larvae plays a key role in damaging guava fruits as it feeds on fruit pulp for its development. 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. It is similar to B. zonata but has a predominantly black scutum. 1977. It was first recorded in China in 1982 in Yuanjiang, in southern Yunnan Province. 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. A quarantine is established against the following pest, its hosts and possible carriers.

In light of ⦠tion on the survival of the eggs and larvae of the guava fruit fly, Bactrocera correcta (Bezzi). 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). B. correcta (Guava FF), etc. The larvae then drop from the fruit to pupate in the soil. 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. Figure 6.

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.

Abdomen rufous above except for black basal marks on terga 2 and 3 and a median black vitta from terga 3 over 5. Photograph taken in Australia. 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. This is the actual fly captured in Apopka, Florida on 4 May 2001. 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.

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. 1980. Front. Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. Larvae hatch in a few days and burrow into interior of the fruit to feed on the pulp for 4 - 12 days. Bactrocera dorsalis and B. correcta are serious pests of agricultural fruit crops. CAB International. The adult female detected in California was found in a methyl eugenol-baited Jackson trap. Many species of Bactrocera have not been well-studied. These eggs get hatched within 1-2 days. %%EOF
Bactrocera zonata, in India called "the Ranchi peach-pest," is very injurious to peach, mango, and several other fruits, including ripe Aegle marmelos (L.)

Family Tephritidae, pp. Within Florida, two flies were captured in the Titusville area (Brevard County) in August 1999. 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.
