The objective of this work was to determine, in the field, the preference of the palm weevil (Rhynchophorus palmarum) for trunks of oil palm (Elaeis guineensis), caiaué (Elaeis oleifera), and for the interspecific hybrid between caiaué and oil palm. The experiment was carried out at the oil palm germplasm bank of Comissão Executiva de Planejamento da Lavoura Cacaueira, Brazil. Among the three tested genotypes, caiaué is significantly less preferred by Rhynchophorus palmarum, followed by the interspecific hybrid, and oil palm.
