Natural enemies in Maine lowbush blueberry

While it is speculated that natural enemies play a role in lowbush blueberry insect pest management, it is unclear how different management practices impact commonly occurring natural enemies and to what extent they reduce insect pest populations. We have found the predominant insect natural enemies to be ground spiders, phalangids, carabids, staphylinids, and hymenopteran parasitoids of the Ichneumonoidea. We report on the diversity and abundance of natural enemies as it relates to the temporal and spatial attributes of blueberry production. We also report on the difference in diversity and species composition between conventionally and organically managed lowbush blueberry fields in Maine and the susceptibility of these natural enemies to the commonly used insecticides.

COMMENTS AND CORRECTIONS

  • From Sophie Gagnon, Agronomist, project manager, Centre de recherche et de développement en agriculture (CRDA), July 18, 2006
    Hi, I take part of the blueberry team of researchers at the CRDA, on Lac-Saint-Jean's region, in Quebec. I am working with four authors on publishing an identification guide (insects, weeds and diseases) in the lowbush blueberry production. We took note of one of your publications that have a great interest for us. I already have the poster, but I would be grateful to you if you should forward me this publication, or say to me how I can have it.
