D3316: Phenology and distribution of ambrosia beetle in Michigan apple orchards

The black stem borer (Xylosandrus germanus) poses a significant threat to apple orchards in Michigan, with many apple growers reporting complete tree death. Understanding the phenology and spatial distribution of these beetles within orchards is crucial for developing effective management strategies. We highlight the spatial distribution patterns and phenology of black stem borer populations within apple orchards. Factors such as tree age, tree health, and proximity to neighboring wooded areas will be reviewed as their potential determinants of spatial distribution. This study provides valuable insights into the phenology and spatial distribution of black stem borer in apple orchards in Michigan. These findings can aid in the development of targeted management strategies to mitigate beetle damage and protect apple orchards from infestation.
