The effect of seed predation by acorn weevils on the acorns of Quercus insignis was assessed in the context of frequency of infestation and the extent of damage incurred by the larvae on individual acorns. The effect of such damage on early fruit abscission and germination potential of infested acorns was also examined in this study. Acorns were collected from five Q. insignis trees in the lower montane forest of the Cordillera de Tilarán in Costa Rica. Frequencies of infestation varied greatly among the five trees, from 3.3% to 75%. However, there was no evidence for early abscission of infested acorns by the parent trees. Finally, the larvae were found to produce considerable damage to individual acorns after abscission that could potenti...
