Resumo(s)
In this study, we address the theory behind
the ecological functions provided by biodiversity
and ecological infra-structures, as well
as their role in enhancing the performance of
natural enemies, in agrarian ecosystems.
This study focuses on the processing tomato
agrarian ecosystem. In this crop, the
key pest is the tomato fruitworm, which is
followed by a complex of natural enemies,
essentially parasitoids. This parasitoid complex
has been monitored from 2002 to 2004
under the scope of the project AGRO 189 –
“Integrated pest management in processing
tomato”; it has been observed that this community
is present in the field every year and
may strongly influence the populations of the
tomato fruitworm.
Some field observations that arose during
field studies are addressed and interpreted
bearing in mind the availability of ecologi-cal infra-structures present in the fields surveyed,
namely aspects related to population
dynamics of both the key pest and its natural
enemies, and to the biodiversity of the parasitoid
complex.
Assuming that natural enemies and pests
benefit differentially from ecological infrastructures,
the possibility of habitat manipulation
of agrarian ecosystems in order to
favour antagonists is discussed.
