The caterpillar of olive, Palpita forficifera, is a major pest of olive cultivation worldwide. This caterpillar damages the olive culture due to its feeding on leaves, especially young shoots, and may also eat fruits at high infestations. Several olive groves were monitored in the municipalities of Santana do Livramento, Bagé, Candiota, Cachoeira do Sul, Pelotas and Rio Grande, Rio Grande do Sul State, since November 2010, aiming to detect the occurrence period and damages caused to olive crops in the State of Rio Grande do Sul. The damages to shoots affect photosynthesis by reducing the leaf area, and the olive yield on the next year, since it is through the shoots that new fruits will be produced. This is the first record of P. forficifera in olive groves in the Rio Grande do Sul, Brazil.
