Plastic mulch effects on ground beetle communities (Coleóptera: Carabidae) in an organic blueberry field

A study was conducted to determine the effect of synthetic mulch on the diversity and abundance of carabid beetles in an organic blueberry crop. The treatments consisted of plastic mulch, plastic mulch combined with pine needles, pine needles only and bare soil as control. Beetles were captured usin...
