Abstract: Commercial tree plantations cover around a million ha in Uruguay, mostly with stands of eucalypt and pine trees. Uruguayan forestry was free of serious insect pest until the end of the twentieth century. Beginning in the 1990s, both forestry area and international trade experienced an exponential growth, followed by an increase of invasive insect records. More than half of the pests currently affecting Eucalyptus entered the country after 1995. The use of pesticides is greatly restricted, provided around 90% of the plantations are under FSC and/or PEFC certification schemes. Hence, the Uruguayan forestry has relied mainly on silvicultural and biological control to suppress insect pest populations. Biological control for forest insect pests in Uruguay can be tracked back to 1941. Currently, biological control with entomophagous or entomopathogenic organisms has been, or is currently being, implemented for eight insect pests in plantations in Uruguay. More than five parasitoid wasps and a nematode have been released and installed in the field. There are also at least two cases of introduction of entomophagous organisms simultaneously with the pest. I discuss the future of biological control in Uruguay, focusing on the advantages it possesses and the challenges it faces under the current pest status. |

ABSTRACT.
Semiarid forests are worldwide threatened by land use changes, particularly agriculture. However, in some cases, due to particular economic or social processes, agriculture ends and forests may or may not recover to their original state. Using different databases and satellite images integrated into a geographical information system, we located in the central region of the semiarid Chaco forests of Argentina adjacent land use patches of secondary forest (SF), remnant forest (RF) and crops (CP). Using a chronosequence approach, we evaluated changes in the fraction of the photosynthetic active radiation absorbed by the vegetation (FAPAR) between SF and RF and CP, using the enhanced vegetation index (EVI). We evaluated both intra and inter-annual changes in EVI mean (EVImean), EVI maximum (EVImax), EVI minimum (EVImin), and EVI relative range (EVIrr) as descriptors of FAPAR dynamics and analyzed their changes through time (2000 to 2010) and their relation to rainfall. Secondary forests showed higher seasonality and higher EVImean values than RF, but differences disappeared as time since agricultural abandonment increased, suggesting that SF recover their functioning (when compared to RF) after 10 to 15 years. Our results suggest that Chaco's SF have intermediate seasonal patterns in-between RF and CP, as expected by successional theory, and that FAPAR interception by RF appears to be dependent on previous year's precipitation. We found that, although all land uses showed similar precipitation use efficiency (PUE), SF and cropland's productivity were less stable across the years and showed faster increases or decreases compared to RF, depending on precipitation (higher precipitation marginal response- PMR). Our results suggest that at least some aspects of ecosystem functioning can be restored after agricultural abandonment. Future research that combines floristic and structural changes is necessary to fully understand secondary forests regrowth process after agricultural abandonment in the Chaco region.
