Abstract A rearing technique was developed for two species of
fruit fly, Bactrocera melanotus (Coquillett) and B. xanthodes
(Broun), and key life-cycle parameters were determined. The technique
included developing a novel larval diet with no bulking agent. The mean
life-cycle parameters for B. melanotus and B. xanthodes,
respectively, at 26 +/- 1deg.C were: egg hatch, 40 h and
44 h; egg to pupa, 10 days for both species; preoviposition period, 21
days and 12 days; egg to egg, 44 days and 35 days. Colonies were maintained in
the laboratory for over 20 consecutive generations. Results are discussed in
relation to production of eggs and various larval instars for postharvest
disinfestation research.
