Unidentified borer found on blueberry bushes in Florida

From Growing Produce

According to a Florida Blueberry Growers Association member alert, several farms have recently discovered signs of an unidentified borer on blueberry bushes. At the time of the alert, no farm had been able to find or catch this insect, but growers were asked to thoroughly scout for any dead plants or holes and sawdust in and at the base of the plants.

Oscar E. Liburd, UF/IFAS professor of fruit and vegetable entomology, was able to get an up-close look at the potential problem as samples with injury on blueberry stems resembling girdling and some levels of tunneling were brought to the University of Florida Small Fruit and Vegetable IPM Lab. “After inspecting the samples with a high powered microscope, we found insect frass inside the tunnels,” he said. “No insects or larvae were recovered; preliminary conclusions indicate that a borer may be causing the injury on blueberry stems; however, further investigation with samples containing larvae is needed to confirm that it is indeed a borer causing the injury.”
