| Sumario: | Damage by Blue-fronted Amazon (Amazona aestiva) to citrus fruits was studied from May to September 1990 in an orchard in the NE of Tucumán province, Argentina. All fruits on the ground beneath 140 sampled trees (orange, lemon, and grapefruit) were counted. Only those fruits exhibiting the characteristic injury produced by Blue-fronted Amazons were accounted for in damage estimates. The damage caused by this psittacid was low (1% in total) and of little economic significance for the orchardist. Oranges were the most affected citrus species (2% damage). |
