Commercial tree plantations cover around a million ha in Uruguay, mostly with stands of eucalypt and pine trees. Uruguayan forestry was relatively free of serious health threats until the end of the XX century. Beginning in the 90?s, both forestry area and international trade exhibited an exponential growth, soon followed by an increase of invasive insect records. More than half of the pests currently affecting Eucalyptus entered the country after 1995. The high percentage of plantation area currently under FSC and/or PEFC certification schemes (90%) restricted the use of pesticides and pushed the Uruguayan forestry to rely mainly on silvicultural and biological control to suppress insect pest outbreaks. However, there was almost no regulations regarding the use of biological control agents until the last decade, even when biological control for forest pests in the country can be traced back to the 1940s. Here, we present the state-of-the-art of biological control in Uruguayan commercial forestry. Currently, biological control with entomophagous or entomopathogenic organisms has been, or is currently being, implemented for eight insect pests. More than five parasitoid wasps and a nematode have been released and installed in the field. There are also at least two cases of adventive introduction of entomophagous organisms, simultaneously with the pest. Building capacity for biological control and improving the regulatory framework are key issues towards the success of biological control of forestry pests under the current pest scenario.

ABSTRACT.
Members of the Fusarium graminearum species complex (FGSC) are the primary pathogens causing Fusarium head blight (FHB), Fusarium graminearum is the main pathogen of FHB and can produce various mycotoxins in wheat, in particular type B trichothecenes. This review presents information on the Fusarium species and chemotypes diversity associated to FHB in wheat in Uruguay. In surveys performed in 2001 and 2002, Fusarium graminearum was the most frequently isolated species (76 %), while other non FGSC species were also identified. Among species from FGSC Fusarium graminearum sensu stricto was the most frequently isolated (97 %), while F. cortaderiae and F. austroamericanum were also identified. The predominant chemotype was 15ADON (95 %), followed by 3ADON (3 %) and NIV (2 %). Isolates identified as F. graminearum sensu stricto were characterized according to the levels of DON production, the aggressiveness on different wheat cultivars, the ability to form perithecia on wheat straw. The sensitiveness to the fungicide tebuconazole of FGSC isolates was evaluated. Most isolates showed high sensitivity levels, but a few resisted higher levels of fungicide. Lower sensitivity seemed to be tied to species since F. cortaderiae isolates showed the highest MIC values. |
