Augmentation of Parasites/Predators - TABLE 3
Spiders are another group of generalist predators that often consume
the most abundant and most easily captured prey in their habitat.
Encouragement of spider populations at present consist of not
disturbing them; or of observing which species may feed on the larvae
and bringing in more of these spiders from elsewhere to feed on the
target fruit flies.
Patch Complex
A variation of the above, involves the employment of patch complexes,
in which a number of areas are set up inside the entire control area to
promote certain ecological situations advantageous for control within
the economic constraints of a program. Inside the patch (or area), a
complex of increased natural diversity is encouraged. Methods
include the introduction of understory trees or bushes to increase the
provision of nesting sites for birds, the encouragement/introduction of
ant colonies, and so forth.
Augmentation of Parasites/Predators - TABLE 3
Various efforts have been made to suppress fruit fly populations
through augmentation of their parasites/predators. This technique is
useful where more traditional methods such as insecticide-bait sprays
and sterile male releases are impractical. The following table
illustrates past procedures:
