Keywords: Bactrocera dorsalis, climate change, geo-graphical distribution, Oriental fruit fly. 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 life cycle from eggs to male (146.95 ± 3.43 d) and female (164.94 ± 3.85 d) adults was significantly longer on papaya than those on banana and guava. Bactrocera dorsalis completed its development at temperatures ranging between 15 and 33 ᵒC with the mean developmental time of egg, larva, and pupa raging between 1.46 – 4.31 days, 7.14 – 25.67 days, and 7.18 – 31.50 respectively. Marjorie A. Hoy, in Insect Molecular Genetics (Third Edition), 2013. 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. Three larval stages develop inside the fruit, feeding on the plant tissue. 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. However, lack of genetic information on this organism is an obstacle to understanding the mechanisms behind its development and its ability to resist insecticides. Five male Bactrocera dorsalis specimens were detected in five separate Methyl Eugenol baited traps in urban areas in the coastal town, Jeffreys Bay between 28 February and 21 May 2019.
