Bactrocera dorsalis females produced significantly more eggs when fed on guava (623.30 eggs female −1) than on papaya (527.80 eggs female −1) or banana (399.60 eggs female −1). The following is a generalized life history for Bactrocera fruit flies. 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. It is one of the major pest species in the genus Bactrocera with a broad host range of cultivated and wild fruits, second in damage only to Bactrocera … Several bacterial genera viz, Listeria, Citrobacter, Enterobacter, Serratia, Vibrio, Proteous and Klebsiella identified from gut of B. dorsalis in the present study were quiet common for other Tephtriitd fruit flies like, Bactrocera tau (Walker), Bactrocera tryoni (Frogatt) Ceratitis capiata (Wiedemann) (Behar et al., 2008; Khan et al., 2014; Kuzina et al., 2001; Wang et al., 2011). The hobo vector transposed in a plasmid-based excision assay in several drosophilid species (Handler and Gomez 1995), and in cells of Trichoplusia ni and Helicoverpa zea (DeVault et al. THE Oriental fruit fly (OFF), Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is a destructive polyphagous pest on a range of wild and cultivated fruit crops1,2. importance of Bactrocera invadens. Three larval stages develop inside the fruit, feeding on the plant tissue. Eggs are minute cylinders laid in batches. parameters of four Bactrocera species (Bactroceracorrecta, Bactrocera dorsalis, Bactrocera cucurbitae, and Bactrocera tau) reared on a semi-artificial diet comprising corn flour, banana, sodium benzoate, yeast, sucrose, winding paper, hydrochloric acid ... can develop through all or part of its life cycle… This species was discovered by Drew and Hancock in 1994. It is a major pest … Keywords: Bactrocera dorsalis, climate change, geo-graphical distribution, Oriental fruit fly. Bactrocera dorsalis (Hendel) is a polyphagous and destructive insect pest of mango fruits which causes yield losses ranging from 5 to 80 per cent (Stonehouse, 2001). ... while in Bactrocera tryoni (Froggatt), B. dorsalis and B. cucurbitae, they are produced in their rectal diverticula [29,30,31,32,33,34]. The female has a pointed slender ovipositor to deposit eggs under the skin of host fruit. Fruit flies have a great influence on fruit and vegetable industry of Pakistan. The d uration of total life cycle was 16.81±2.18days during 2015 in June and July under room temperature in meerut condition. Oriental fruit fly (Bactrocera dorsalis) covers 4 previously described fruit fly species: Bactrocera dorsalis, B. papayae, B. philippinensis and B. invadens. The adult flies congregate on foliage and fruit to feed on bacterial colonies and later to mate. The oriental fruit fly, Bactrocera dorsalis (Hendel), is an important and destructive pest species that can infect many commercial tropical and subtropical crops (fruits and vegetables) worldwide, resulting in severe economic losses (Clarke et al. Many species of Bactrocera have not been well-studied. near Bactrocera dorsalis A), xoas conducted in the laboratory (26.5°C± 1.5°C). Outline 1.Background 2.General life-cycle of fruit flies 3.Biology of B. invadens 4.B. total life cycle was finalized in 24.50 to 46.50 days on different hosts however; it was little on mango than rest of the fruits. The adult oriental fruit fly is somewhat larger than a housefly, about 8 mm in length. The oriental fruit fly, Bactrocera dorsalis (Hendel) belongs to the B. dorsalis complex. Mated females deposit eggs within the flesh of the fruit on a host plant.Larvae hatch in a few days and burrow into interior of the fruit to feed on the pulp for 4 - 12 days. Primers for the amplified of the complete mitochondrial of Bactrocera dorsalis, Bactrocera papayae, Bactrocera carambolae, Bactrocera philippinensis, were designed based on the complete mitochondrial genome of Bactocera oleae and Ceratitis capitata in GenBank. Keywords: Bactrocera dorsalis, climate change, geo-graphical distribution, Oriental fruit fly. A study ofthe life-cycle ofBiosteres persulcatus Silvestri, a larval parasitoid of (Bactrocera (B) sp. 9.15.5 hobo. Bactrocera dorsalis females produced significantly more eggs when fed on guava (623.30 eggs female-1) than on papaya (527.80 eggs female-1) or banana (399.60 eggs female-1). Biology and morphometry of different life stages of oriental fruit fly, Bactrocera dorsalis on custard apple reared under laboratory condition Ashoka KS, B Thirupum Reddy, Bharathi MC and Abhishek BM Abstract The oriental fruit fly Bactrocera dorsalis (Hendel) is a very serious pest of fruit crop globally causing considerable economic losses.
