| Sumario: | In Argentina, agroecology has grown in last years as a scientific paradigm that
seeks to design and evaluate agroecosystems considering sustainability, complexity, and uncertainty.
Diversity is a key factor in the design and management of production systems and a
necessary component for conservation biological control and the reduction of agrochemicals
use. Cotton (Gossypium hirsutum) crop in northern Argentina is usually managed with high
load of agrochemicals: agroecological production arises as an alternative. This study evaluated
the diversity, richness, and abundance of soil arthropods using pitfall traps in two experimental
cotton plots under conventional (CONV) and agroecological management (AE) in
Chaco, Argentina. AE system presented higher diversity and richness of predators compared
with CONV, even when natural preparations were used for pest control. The phytophagous
arthropods showed higher diversity and richness in CONV, even when pyrethroid insecticides
were applied for pest control and preventively. The abundance in AE was lower for predators
and higher for phytophagous arthropods. Agroecological production of cotton can be a tool
that favors conservative biological control and an alternative for areas where protecting the
health of farmers and the ecosystem is a priority. |
