Investigations into the Ecology of Microtheca ochroloma and control methods for organic farmers

Objectives The original objectives of the project were as follows: 1. To determine if beetles remain active into summer if crucifers are present under field conditions. 2. To determine if initial infestation of M. ochroloma arise from within the field from the soil subsurface or whether beetle enter the field from field edges after oversummering. 3. To determine whether intercropping crucifers protects them from YMLB by hiding them among non-host plants. 4. To determine if cutting crucifers makes them easier for the beetles to find, therefore increasing infestation.
