bactrocera correcta life cycle

1973. Adult female oriental fruit fly, Bactrocera dorsalis (Hendel), laying eggs in fruit. Ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). The other principle species recorded were B. dorsalis and B. zonata, although they were not as abundant as B. correcta. Larvae hatch in a few days and burrow into interior of the fruit to feed on the pulp for 4 - 12 days. Pupation occurs in the soil. A genetic sexing strain (GSS) is an essential component for pest control using the sterile insect technique (SIT). Abdomen rufous above except for black basal marks on terga 2 and 3 and a median black vitta from terga 3 over 5. Ovipositor tip of an adult female guava fruit fly, Bactrocera correcta (Bezzi). 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. 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. Triology, Vol 47, No.1.

Alston (as Eugenia jambos) (roseapple), and Ziziphus spp., including Ziziphus jujuba Mill. 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 . Bactrocera zonata Bezzi.

Description Bactrocera correcta (Bezzi, 1916), commonly known as the guava fruit fly, is of concern as an invasive pest in tropical and subtropical countries. 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. Front. The wings are clear with a light brown band along the leading edge and a spot at the tip. Sterna of both Bactrocera dorsalis performed better than B. correcta in the 37–40°C hardening range, while B. correcta differed from B. dorsalis in the 34–36°C range. This is the actual fly captured in Apopka, Florida on 4 May 2001. For integrated management of both Bactrocera species, understanding their olfactory behavior is vital for designing reliable control strategies. Jallundur, India. 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.

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).

On the fruit-flies of the genus. 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. Oxon, UK. Both are strongly attracted to methyl eugenol.Malaysia has also completed a thorough nation-wide survey of fruitfly. Hosts: Important hosts include mango, peach, orange, jujube and tropical … The adult female detected in California was found in a methyl eugenol-baited Jackson trap. In recent years, B. … The guava fruit fly, Bactrocera correcta, is one of the major pests affecting mango (Mangifera indica) and guava (Psidium guajava) production in China. No stages develop at 15°C or less, the optimum temperature is 25-30°C (Qureshi et al., 1993). Figure 2. Two additional adult males were detected in Orange County on 9 August 1986. Once sexual maturity is reached (which takes approximately 9 days), adults engage in the mating process and the life cycle repeats. 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). 601 pp. He indicated that Bactrocera correcta is readily differentiated by having the mesonotum predominantly black through the median portion of the mesonotum, covered with gray pubescence and with three rather indistinct subshining black, narrow vittae, rather than rufous; and usually by having a complete transverse band in the furrow across the lower part of the face, rather than the usual two black facial spots of related species. Microreticulation near base of the ovipositor of an adult female guava fruit fly, Bactrocera correcta (Bezzi). 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, … Larval: Larvae plays a key role in damaging guava fruits as it feeds on fruit pulp for its development. 1977.

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. hÞbbd```b``þ"H¦• ’ÕÌv“'@$ÛzÉRYV3,þ̞&÷ƒIe0é"'öIÆ¢Ý vRˆd‰0øY‚Ùš Ù41°™;A¤{=\œAùX¼DòùÉú[˜€nn»–‘æä&•÷ xj‚ Closeup of ovipositor tip of an adult female guava fruit fly, Bactrocera correcta (Bezzi). It is similar to B. zonata but has a predominantly black scutum. RT-PCR revealed that B. dorsalis tra (Bdtra) and B. correcta tra (Bctra) transcripts contained conservation of both constitutive exons and male-specific exons as in other Bactrocera.However, new Bdtra male-specific exons were retained, diversifying the pattern of the male-specifically spliced transcripts. 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.

Bactrocera correcta occurs in India, Pakistan, Nepal, Sri Lanka, and Thailand. Anderson PJ, Dixon WN. 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. Life History Development from egg to adult under summer conditions requires about 16 days. These eggs get hatched within 1-2 days. Figure 8.
