Carpophagous insects of holm oak in southern Spain and their susceptibility to Beauveria bassiana native isolates


Abstract: The carpophagous insects Curculio elephas, Cydia fagiglandana and Cydia splendana are cause of damage to the Quercus trees in southern Spain. We have investigated the insecticidal activity of Beauveria bassiana isolated from these carpophagous insects, on larvae of their respective natural hosts, as well as their cross activity. In addition, the activity of an isolate obtained from the lepidopteran defoliator Phycita sp. was evaluated on these carpophagous species.
