Efficacy of Trap Test capturing of chestnut tortix moth (Pammene fasciana L., Cydia fagiglandana (Zell.) and Cydia splendana Hb.) in Central Italy

Many phytophagus are reported to cause damage to chestnut trees (Paparatti et al. 1998, Pollini 1998, Cinti et al. 1995). However a recent survey carried out in Central Italy has identified chestnut weevil (Curculio elephas Gyll.; Coleoptera, Curculionidae) and tortrix moths (Pammene fasciana L., Cydia fagiglandana (Zell.) and Cydia splendana Hb.; Lepidoptera, Tortricidae) as the most damaging pests of chestnut fruits (Speranza, 1999). During the last years the damage caused by the over cited insects increased remarkably. In order to have an idea of the flight activity of these pests, it has been decided to investigate the presence of adults of the 3 species of tortrix moths in 3 chestnut orchards in the area of the Monti Cimini, Viterbo (IT). Surveys have been carried out in the period 1997-1998
