Holistic approach for an effective control of white grub of European cockchafer (Melolontha melolontha) in organic strawberryplantations in Poland

摘要

In recent years, in Poland, it has been registered an increasing threat to crops, particularly organic ones, from the white grub of European cockchafer (Melolontha melolontha L.) and forest cockchafer (Melolontha hippocastani L), with strawberry plantations being among the most vulnerable. Due to the pests' biological cycle, which make difficult the control, we have developed a holistic strategy aiming at the control of these soil-borne pests which includes the use of various biocontrol agents (BCA) andagronomical methods (physical and rotation). For biocontrol, agents such as entomopathogenic fungi (Beauveria bassiana, Beauveria brongniartii, Metarizum anisopliae,) and entomopathogenic nematodes (Heterorhabditis bacteriophora^ allowed to reduce the soil population of grubs. The strategy has resulted in a high efficacy in controlling the grubs.
