A quarantine is established against the following pest, its hosts and possible carriers. 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. In light of … Anterior view of an adult guava fruit fly, Bactrocera correcta (Bezzi). 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). Ovipositor of female red, rather short, measuring approximately 3.0 mm when fully extended. Larvae hatch in a few days and burrow into interior of the fruit to feed on the pulp for 4 - 12 days. The major fruitfly species in Thailand are Bactrocera correcta and B. dorsalis. 601 pp. Photograph by Division of Plant Industry. Figure 2. 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. Front. Photograph by Division of Plant Industry. 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. Fruit Flies of Economic Significance: Their Identification and Bionomics. Two additional adult males were detected in Orange County on 9 August 1986. This stage of larvae development takes around 10-12 days. 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. Export India Publications. Many species of Bactrocera have not been well-studied. There is no developmental information on B. correcta, but it is probably similar to B. zonata and B. … 111 pp. B. correcta (Guava FF), etc. 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). The guava fruit fly, Bactrocera correcta, is one of the major pests affecting mango (Mangifera indica) and guava (Psidium guajava) production in China. tion on the survival of the eggs and larvae of the guava fruit fly, Bactrocera correcta (Bezzi). In recent years, B. … These eggs get hatched within 1-2 days. In this study, the response of female B. dorsalis and B. correcta … Egg: Eggs are laid in fruit by female. It is similar to B. zonata but has a predominantly black scutum. 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. No stages develop at 15°C or less, the optimum temperature is 25-30°C (Qureshi et al., 1993). 293 0 obj <>stream Full-grown larvae enter the soil for pupariation. 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. Bactrocera correcta is a brightly colored little fly, predominately black with lateral yellow stripes, approximately 5.4 mm in length. 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, … 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%. Piercer gradually tapered to a short point, about 1.0 mm in length. Photograph by Division of Plant Industry. 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. Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. A genetic sexing strain (GSS) is an essential component for pest control using the sterile insect technique (SIT). (August 2002). Microreticulation near base of the ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). Figure 7. Hardy DE. Kapoor VC, Hardy DE, Agarwal ML, Grewal JS.

The mature larva emerges from the fruit, drops to the ground, and forms a tan to dark brown puparium. The adult female detected in California was found in a methyl eugenol-baited Jackson trap. Ovipositor tip of an adult female guava fruit fly, Bactrocera correcta (Bezzi). Bactrocera correcta occurs in India, Pakistan, Nepal, Sri Lanka, and Thailand. 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. Larvae can be collected from infested fruit, killed in boiling water, and placed in 50% alcohol for two days, then to 75% isopropyl alcohol, but specific identification based solely upon larvae is difficult. 0 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), 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… 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.
