Managing the low sensitivity of codling moth against the codling moth
Project
Project code: 2805OE023/1
Contract period: 01.01.2006
- 31.12.2009
Budget: 331,490 Euro
Purpose of research: Applied research
The apple developer granulovirus (Cydia pomonella granulovirus, CpGV) is one of the most important control agents of the codling moth in organic apple growing dar. Since 2003, more individual apple beobachtetet developer populations, which have a factor of 1000 lower susceptibility to virus preparations and practically with the virus do not longer be controlled. An extension of this phenomenon poses a significant threat to the efficient control of the codling moth in organic cultivation dar. To further spread of the phenomenon to be avoided, to targeted population genetic studies of Apfelwicklerpopulationen in Germany are carried out and their basic sensitivity to the CpGV are investigated. Furthermore, the genetic and biological mechanisms are elucidated the reduced sensitivity of the codling moth against CpGV. For this purpose, crossing experiments between susceptible and less susceptible to be carried out Apfelwicklerpopulationen. Based on the results should be developed with affected businesses practice strategies to prevent the spread of the phenomenon and help enable the successful and sustainable use of CpGV preparations.
