Grape cane girdler

Grape cane girdler
Rufus Isaacs, MSU Entomology

The grape cane girdler is a black snout beetle. In late spring, the female makes holes encircling the cane and lays her eggs in the holes. She then encircles the cane with anoth-er series of punctures a few inches below the first girdle. The leg-less grub is white with a brown head and feeds in the cane pith between the girdles. After larvae com-plete their development, they pupate. Adults appear in late summer and hibernate over the winter. Injury from this insect has the great-est impact on vines during establishment.
