and Their Speculated Dominancy over Native Fruit Fly Species in Tanzania]]>MwatawalaM.W. MeyerM. De MakundiR.H. MaerereA.P. 1200961The dominancy of introduced Bactrocera species
(Diptera: Tephritidae) over the native fruit fly species was assessed
based on data collected from a trapping and sampling program in Morogoro,
Tanzania, from 2004 to 2006. Two invasions by Bactrocera species
namely the invasive fruit fly Bactrocera invadens Drew, Tsuruta
and White and the Solanum fruit fly Bactrocera latifrons (Hendel)
have been recorded in 2003 and 2006, respectively. These add to an earlier
introduced melon fly Bactrocera cucurbitae (Coquillett). Points
and exact times of entry of these species are still unknown. Dominance
of Bactrocera species over the native Ceratitis species
has been speculated from other parts of the world. Results of this study
also suggest the dominancy of Bactrocera species over native Ceratitis
species in Tanzania. B. cucurbitae seems to dominate the other
cucurbit infesters in terms of abundance and infestation rate. Similarly,
B. invadens seems to dominate the native Ceratitis species
in orchard fruits in terms of abundance, host range and infestation rate.
B. latifrons, whose distribution in the country is still unclear,
seems to be the dominant species in its main hosts from family Solananaceae.
The outcome of the competition resulting from these introductions is speculated
upon. Presence of these pests calls for strong surveillance systems and
quarantine regulations to protect the infant fruit industry of Tanzania.]]>Byers, J.E.,20008112251239CABI.,20051st Edn.,Copeland, R.S., R.A. Wharton, Q. Luke and M.
