| Summary: | The apiines (Hymenoptera : Braconidae) are important
parasitoids of the oriental truit fly. Bactrocera dorsalis
(Hendel) (Diptera : Tephritidae). In an attempt to exploit
their potential in the integrated control of this pest. field
and laboratory studies were conducted to generate information
about the biology and abundance of the major species,
Based on contribution to overall parasitisation. the opiine
parasitoids associated with B. dorsalis in star fruit can be
arranged in the following order of importance : Biosteres
persulcatus Silvestri, 46.53% B. arisanus (Sonan), 32.82% B. lonqicaudatus Ashmead, 5.69% Opius fletcheri Silvestn,
4.95%. field populations of fruit fly and parasitoids had two
peak periods yearly, and both were significantly correlated
with abundance of their respective host, except B.
lonqicaudatus. However, their activities were significantly
unaffected by size and height of host fruit in the tree. |
