Photograph by Pest and Diseases Image Library, Bugwood.org. 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). Figure 11. Legs mostly yellow. A guava fruit fly. Figure 8. Life Cycle of Fruit Fly is divided in to four stages . Figure 3. 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. Bactrocera correcta occurs in India, Pakistan, Nepal, Sri Lanka, and Thailand.

Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. Adults emerge 7 - 10 days later and feed for a period of ti… A GSS is developed using a combination of Y-autosome translocation and a selectable marker such as pupal color, resulting in heterozygous males and homozygous females that possess wild … endstream endobj 246 0 obj <. Figure 2. Dacus (Strumeta) correctus (Bezzi) Egg: Eggs are laid in fruit by female. 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. Within Florida, two flies were captured in the Titusville area (Brevard County) in August 1999. Adult female guava fruit fly, Bactrocera correcta (Bezzi). Microreticulation near base of the ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). The following is a generalized life history for Bactrocera fruit flies. Adult female oriental fruit fly, Bactrocera dorsalis (Hendel), laying eggs in fruit. The effect of temperature on the development and survival of the guava fruit fly,Bactrocera correcta (Bezzi) (Diptera: Tephritidae) from egg to adult’s pre-ovipositional stage was studied in laboratory under 5 different constant temperatures: 18, 24, 30, 33 and 36°C. Larvae of many species of fruit flies are unknown. Photograph taken in Australia. Two additional adult males were detected in Orange County on 9 August 1986. Cubital cell faintly yellow and no cubital streak developed. It has spread to other parts of the world, in particular to several countries in the Near East and to Egypt. 11:451. doi: … 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. A quarantine is established against the following pest, its hosts and possible carriers.

Figure 7. Mated females deposit eggs within the flesh of the fruit on a host plant. (ber, jujube, Chinese date). Description Bactrocera correcta (Bezzi, 1916), commonly known as the guava fruit fly, is of concern as an invasive pest in tropical and subtropical countries. 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. Oxon, UK. For integrated management of both Bactrocera species, understanding their olfactory behavior is vital for designing reliable control strategies. %PDF-1.6 %âãÏÓ The adult female detected in California was found in a methyl eugenol-baited Jackson trap. 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 … We monitored the spread of B. correcta in the field during 2017 and 2018, and found that it had … This stage of larvae development takes around 10-12 days. sexes entirely yellow. Wing of an adult guava fruit fly, Bactrocera correcta (Bezzi). Family Tephritidae, pp. Basal segment short, approximately equal in length to terga 5 and 6 and about 0.8 mm long. The duration of various immature stages varies at different temperatures. 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. Hardy DE. 1977.

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. 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. The results the females’ 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 … Anterior view of an adult guava fruit fly, Bactrocera correcta (Bezzi).
